Kinship testing in forensic casework is largely based on a likelihood ratio (LR) approach with short tandem repeat (STR) markers; however, in order to efficiently identify potential relatives in a specific population, the threshold values for kinship prediction should be determined by analyzing the kinship index distributions of the population in question. In this study, 250,000 DNA profiles were simulated using allele frequencies at 20 autosomal STR loci in Koreans, then the LRs were calculated for true close relatives and unrelated pairs. The LR distributions in related and unrelated pairs under a given relationship were compared in 2 sets of 13 Combined DNA Index System (CODIS) and 20 STR profiles. Using 13 CODIS STRs, true relatives in parent/child and full-sibling relationships were sufficiently discriminated from unrelated pairs with LR thresholds of 1,000 and 100, respectively. However, the CODIS STRs lacked the discriminatory power to differentiate between related and unrelated pairs in uncle/nephew and first cousin relationships due to high false-positive and false-negative rates with a LR threshold of 10. Increasing the number of STR loci to 20 increased discrimination of close relatives, but high false results remained in uncle/nephew and first cousin relationships. The kinship index data from this study will help make decisions on various kinship testing and familial searching in Koreans.

The goal of cleft lip surgery is to reconstruct normal shape of the lip. To acomplish this goal, various operative method were contrived and concept of the method decided the shape of reconstructed lips. According to the operative result, some operative methods were disappeared or have been developed with a little modifiation. Traditional Millard's rotation-advancement method for unilateral cleft lip patients is largely accepted and developed as proper method for acquiring these functional and anatomic purposes. As a trial for this development, Mulliken add some modifications. He uses exaggerated high rotation incision and it lengthens into midcolumella without backcut. Also he dosen't steal from alar base or lateral lip for vertical height. C-flap is used to lengthen the affected columella and upper lip. The isolated orbicularis oris muscle is coaptated each other for more functional result. With supraperichondral dissection of alar cartilage and transpositioning of caudal septum, he performs synchronous repair of cleft lips, nose and sometimes alveolus. It is still debated when is most suitable age for surgical correction of nasal deformity of cleft lip patients. Done at the time of primary lip repair, there are both some apprehension and inducement. The former are based on technical difficulties due to shortage and fragility of neonatal tissue and possibility of progressive deformities with growing because of iatrogenic injuries to the alar cartilages. But te latter is rationalized because early reposition of deformed nasal cartilage in proper position would induce more natural growth of nasal structures. Some long-term follow up reports reveal the early operation innocent of any growth deterioration. Mulliken treats his cleft lip patient for separated lip and nasal deformities with single operation, and does gingiovoperiosteal alveoloplasty at the same time if necessary. He uses Latham appliance from 4 to 6 week after birth in case of severly collapsed lateral alveolar segment or wide alvolar gap, and perform the definitive opertation at the age of 4 to 6 months. I use lip adhension method to correct more than 10 mm alveolar gap without severe collapse of lateral alveolar segment, but if lateral segment was severely collapsed and away from alvolar arch, I apply the Latham appliance somewhat modificate from original type, which has a metal ring fastened at the front limb of appliance for rubber banding to coaptate easily. I have experienced repair of cleft lip by Mulliken's concept with some modification of my own to 44 cases of unilateral cleft lip patients and conclude that it was very flexible method. Doing with synchonous repair of cleft lip nose, we could get harmonious lip and nose with symmetric nostril sill, cupid's bow and red line. Columella was lengthened primarily. Normal growth of nose was anticipated by anatomic repositioning of alar septal cartilage.

To determine size and shape discrepancy between the bone of Korean women and the prostheses in total knee arthroplasty, the height(antero-posterior length) and width(medio-lateral length) of the distal femur and the proximal tibia were measured at the bone resection level for 104 knees of 62 female patients who underwent primary total knee arthroplasty and compared with the same parameters of the total knee prostheses designed by five different companies. On the condition that the height of the prostheses matched with each cases of the bone were optimal, the difference in the width was evaluated, and the criteria of the discrepancy were overhang if the width of the prosthesis was larger than bone, optimal if width of the prosthesis was same or smaller and difference was within 5 mm, and down-size if smaller and difference was over Smm. In femoral prostheses, 34.6% of all were optimal, 13.1%, overhang and 52.3%, down-size. In tibial prosthesis, 54.1% of all were optimal, 13.9%, overhang and 32%, down-size. In conclusion, although further investigation for clinical application is needed, there were discrepancies in size and shape between the femur and tibia of Korean women and total knee prostheses and improvement in design should be considered.

Biofilms are commonly associated with an increased risk of catheter-associated infection. To study the efficacy of materials designed to reduce biofilm formation, microbial biofilms on clinically used urinary catheter were examined. We performed 2, 3-bis (2-methyoxy-4-nitro-5-sulfo-phenyl)-2H-tetrazolium-5-carboxanilide (XTT) reduction assay to determine of biofilm formation ability and observed with scanning electron microscopy (SEM) to analyze biofilm architecture. Additionally, we calculated relative cell surface hydrophobicity (CSH) to measure hydrophobicity of microorganisms. On SEM, catheter surfaces made of latex or anti-infective (IC)-latex were rough but those of silicone, hydrogel-coated silicone (HCS), or silver-alloy-coated silicone (SCS) were relatively smoother. According to XTT reduction assay, biofilm formation was reduced on the surface of smooth silicone-based catheters compared to rough latex-based catheters. The greatest to lowest formation of microbial biofilm were as follows for these material types: silicone-elastomer-coated (SEC) latex > latex > silicone > IC-latex > HCS > SCS. Catheter materials can affect the microbial biofilm formations. First, rougher surfaces on the catheter made the microbial attachment easier and a greater amount of biofilm was formed. Second, when chemicals that inhibit growth and attachment of microorganisms on the inner and outer surfaces of the catheters were applied, the biofilm formation was inhibited. SCS was found to be the most effective in reducing the microbial biofilm formation. These results indicate that microbial biofilm formation may be closely related to the surface roughness and microbial CSH.

PURPOSE: Candida albicans is an opportunistic pathogen that is commonly found in human microflora. Biofilm formation (BF) is known as a major virulence factor of C. albicans. The aim of this study was to examine the influence of bacterial presence on biofilm formation of C. albicans. MATERIALS AND METHODS: The BF of Candida was investigated when it was co-cultured with C. albicans (C. albicans 53, a yeast with a low BF ability, and C. albicans 163, a yeast with high BF ability) and bacteria. BF was assessed with XTT reduction assay. A scanning electron microscope was used to determine the structure of the biofilm, and real-time reverse transcriptase polymerase chain reaction was used to amplify and quantify hyphae-associated genes. RESULTS: Co-culturing with two different types of bacteria increased the BF value. Co-culturing with C. albicans 53 and 163 also increased the BF value compared to the value that was obtained when the C. albicans was cultured individually. However, co-culturing with bacteria decreased the BF value of C. albicans, and the BF of C. albicans 163 was markedly inhibited. The expression of adherence and morphology transition related genes were significantly inhibited by co-culturing with live bacteria. CONCLUSION: Bacteria have a negative effect on the formation of biofilm by C. albicans. This mechanism is the result of the suppression of genes associated with the hyphae transition of C. albicans, and bacteria particles physically affected the biofilm architecture and biofilm formation.

BACKGROUND: The level of physical adaptation through active lifestyle can result in changes in appetite; and caused by physical activity and exercise, physical adaptation may change carbohydrate and fat metabolism during exercise. This study investigated the differences in carbohydrate and fat metabolism after moderate treadmill running and the difference in appetite response before and after exercise in active, regularly exercising individuals and those inactive. METHODS: We analyzed the effects of moderate physical activity (70% of oxygen uptake reserve, 30 minutes on the treadmill) on free fatty acids, glucose, growth hormone, insulin and an appetite visual analogue scale (VAS). Our subjects included 28 healthy males who were divided into two groups, the activity group (n=14) and the inactivity group (n=14) according to the International Physical Activity Questionnaire (IPAQ). The serum samples and VAS were collected at pre, post and 30 min post-exercise. RESULTS: The results of the serum analysis showed no significant effects on free fatty acids, glucose, growth hormone and insulin between the groups, but showed significant changes in free fatty acids and growth hormone between points of measurement. Significant increases in VAS were seen with moderate exercise in both groups, with the inactivity group expressing greater hunger than the activity group. CONCLUSIONS: This study found that inactive persons were hungrier than active persons after moderate exercise. This information might be useful to staff and participants of weight loss programs.

Akt, heat shock protein (HSP72)72, and HSP90 induced by ischemic preconditioning protect cells from the ischemic injury. The purpose of this study was to examine the alterations of the level of phospho-Akt, HSP72, and HSP90 in the rat tibialis anterior and soleus muscles after cyclic episodes of ischemic preconditioning. Sprague-Dawley rats aged 35 weeks were divided into control and ischemic preconditioning (IP) groups. The IP group was divided into 3 subgroups based on cycles of IP. Left common iliac artery was occluded 3, 6, and 10 times for 5 minutes, followed by 5 minutes reperfusion. The experimental animals were sacrificed at 0, 3, 6, 24, and 72 hours after reperfusion, and left tibialis anterior and soleus muscles were removed. The expression of phospho-Akt, HSP72, and HSP90 were examined with immunohistochemical methods and Western blot analysis. The results were as follows; 1. In the 3 and 6 times of IP groups, the expression of phospho-Akt (p-Akt) was increased at 0 and 3 hours after reperfusion, compared with control group. The expression of p-Akt in the 10 times of IP group was lower than that in 3 and 6 times of IP groups. At 72 hours after reperfusion, the expression of p-Akt showed no difference among the IP groups. The expression of p-Akt was higher in Soleus than that in Tibialis anterior. 2. The expression of HSP72 in 3 times of IP group increased at 0 and 3 hours after reperfusion, compared with 6 and 10 times of IP groups. The expression of HSP72 in the 10 times of IP group was lower than that in 3 and 6 times of IP groups. At 72 hours after reperfusion, the expression of HSP72 showed no difference among the IP groups. The expression of HSP72 was higher in Soleus than that in Tibialis anterior. 3. In the 3 and 6 times of IP groups, the expression of HSP90 increased at 0 and 3 hours after reperfusion, compared with control group. The expression of HSP90 in the 10 times of IP group was lower than that in 3 and 6 times of IP groups. At 24 hours after reperfusion, the expression of HSP90 showed no difference with increasing episode of IP. The expression level of HSP90 was higher in Soleus than that in Tibialis anterior. These findings suggest that ischemic preconditioning increases the expression of p-Akt, HSP72 and HSP90 at early phase after reperfusion in the rat tibialis anterior and soleus muscles. However, increased cycles of ischemic preconditioning may not induce the expression of them.

Operating Room nurses are required to have special skills and knowledge to do their job. However, because there is no systematic education program, which considers special circumstances in the OR, novice nurses have a great deal of difficulty adapting themselves to the work environment. The purpose of this study is to develope a multimedia education program, which provides the systematic learning environment, so novice nurses can adapt to the OR environment more effectively. This study has been implemented according to Computer Assisted Instruction Design Model(Il-Joo Na and In-Sung Jung, 1990), which goes through the following steps; 1). Education program analysis 2). Development, evaluation 3). CompletionLearning goals, objectives, motive strategy, and analysis of the education program are analyzed by the concepts based on basic education materials for novice surgery nurses of 6 Medical Centers in Seoul and 'Development of the job training program for newly employed nurses in operating rooms. 'written by Ji-Young Yoon(2000). We divided 9 areas of the contents in surgery education; 1. Basic orientation 2. OR nurses' roles and responsibilities 3. Asceptic technique 4. Disinfection and sterilization 5. OR safety 6. OR nursing care 7. Surgical positioning 8. OR Material management 9. Anesthetic care. We selected asceptic technique, which is the most fundamental concept in OR nursing care. The program screens consist of cover screen, screen for guide, mini menu screen, and test screen. We distributed questionnaires to fifteen experts and investigated their opinions to analyze learning contents and effects of the Courseware. The education program was modified based on respones provided by experts. This study offers an educational program, which allows the individuals to choose the areas they want to learn. The program is easy to use, which encourages the individuals to search for additional information more than one area.
