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.

In the East, Probably one of the most commonly performed esthetic operation is the piercing of the earlobes for earring. the complication of this procedure includes infection, the formation of the hypertrophic scar or keloid, and tearing. Keloid formation is one of the disaterous common complications of the ear piercing. the patients regard the keloid as a cosmetic blemish and they complain that they cannot wear earrings. We have experienced 5 patients of earlobe keloid complicated from piercing of the earlobes. We used intralestional steroid njection, in conjunction with surgical excision and pressure therapy for treatment of the keloid. Among various techniques for reconstructing a piercing, we chose modified Pardue's method for artificial earlobe cleft after wide excision of the keloid. the result was good and satisfactory without any complication after 4 to 24 months of follow-up. the purpose of this paper is to present a simple method of treatment of the earlobe keloid with preservation of the perforation for an earring.

OBJECTIVE: This study was performed to evaluate the effect of cervical cerclage and the clinical characteristics in incompetent internal os of the cervix (IIOC). METHODS: A study was conducted on 170 patients with IIOC, 199 cases of IIOC were admitted and treated with McDonald operation or modified Shirodkar operation at department of Obstetrics and Gynecology Il Sin Christian Hospital from January 1. 1994 to December 31. 1998, of this 14 cases were follow up lost, so 185 cases were analyzed. RESULTS: 1) The incidence of IIOC was 0.43%, 1 in 233 deliveries. 2) The mean age of IIOC patients was 30.54yrs old and the most frequent age group was in 30-34yrs old group (43.78%). 3) The average number of gravida and parity before operation were 4.71 and 1.62. & the success rate of operation was low at high gravida & parity. 4) The predisposing factor was previous history of dilation & curettage (43.75%), Cx. laceration after delivery (6.49%), midtrimester termination (4.32%) etc. 5) The operation methods were McDonald operation (91.35%) and modified Shirodkar operation (8.65%) & the success rate of McDonald operation and modified Shirodkar operation were 85.80% and 87.50%. 6) The successful fetal salvage rate was 85.95% and the highest success rate was 87.50% in 14-16 weeks of gestation group. 7) The more cervix dilate, the more failure occurred. 8) The causes of operation failure were premature rupture of membrane (50.00%), preterm labor (34.62%), FDIU, anomaly, APH etc. 9) The delivery methods after operation were vaginal delivery (65.54%), cesarean delivery (34.46%). CONCLUSION: The 14-16th weeks of gestation group & no cervical dilatation have higher success rate indicating that early diagnosis and appropriate timing of operation is associated with a greater operation success rate.

BACKGROUND: CD34 positive cell enumeration by flow cytometry is currently used to determine the optimal timing of peripheral blood stem cell collections (PBSC) and to predict engraftment of stem cell transplantation. However, the technical problems and lack of a standardized method are sources of significant variability in the quantitation of the CD34 positive cells. ProCOUNT(TM) (Beckon Dickinson Immuno- cytometry System, USA) kit for three color flow cytometric analysis was introduced to enumerate CD34 positive cells using a standardized method. This study was conducted to evaluate the usefulness of the three color method, ProCOUNT(TM), in comparison with two color method. METHODS: CD34 positive cells from 25 cord blood samples were enumerated by two methods, two color (CD34-PE/CD45-FITC) and three color (ProCOUNT(TM) , nucleic acid dye/CD34-PE/ CD45-PerCP) flow cytometric analysis, in which CD34 positive cells were counted directly in comparison with counting beads introduced in the sample. RESULTS: The count of CD34 positive cells in the cord blood was 28.3(+/-20.0)/uL and 20.9 (+/-16.0) /uL by three color and two color methods, respectively, The number of CD34 positive cells enumerated by ProCOUNTTM kit was well correlated with that by two color method, but the count was significantly higher in the former method (p<0.01). CONCLUSIONS: In the three color method, loss of stem cells was significantly lower than that in the two color method, and it was possible to obtain a direct count of CD34 positive cells by using a standardized procedure.

The purpose of this study was to verify the use of Seo's Elderly Stress Scale (SESS), which was developed in 1996. Through the modified tool, it is possible to examine the stress of Korean elders and to contribute to the welfare of them. The subjects were 350 elders over 65 years old who live in Seoul, Kwang-Ju, Yang-Ju Gun Kyung-ki Do, Ui-Jong Bu, and Young-Am Kun, Jeun-Ra Nam Do. the data of 331 elders (94%) were analyzed. Data were collected between January and March in 1996 and analyzed using the SPSS Win 8.0. The result are as follows: 1. Items with low correlation with the total items were removed. So 27 items were removed and 37 items remained. This 37 items were death in the family and/or close friends, family member's behavior not meeting expectations, marriage of daughter, marriage of son, friction with daughter- in-law, argument among children, children refuse to live with parent, children leaving home, sex injury or accident, in frequest visits from children and grandchildren, providing care for your daughter or daughter-in-law post-partum, decrease in decision making and authority in home, Lunar new year and the harvest featival, house sitting, working in the house, performing a sacrificial rite, missed birthday, not living with the eldest son, decreased eyesight, decreased strength, decreased memory, sleep pattern changes, thoughts about death, loneliness, decreased hearing, change of dental condition, change in your diet or eating style, difficulty in self care, moving because of disease or aging, argument with friend or neighbour, travel, dealing with the procedure of heritage, loss of money or property, not enough pocket money, hearing on elderly neglect in television or radio, hope of going home and ignorant from others. 2. Overlapped items were discussed by colleagues and were modified. 'marriage of daughter' and 'marriage of son' were modified in 'marriage of children'. 'self injury or accidents' and 'family accidents' were modified in to self or family accidents. 3. Factor analysis was done in order to identify validity and three factors were obtained from the result. The first factor familial relation area, included 17 items. The second factor, physical area, included 9 items. The third factor, psycho-socio-economic area, included 9 items. Cronbach coefficient alpha for the 35 items was .923. 4. Pearson's correlation was .704 between SESS and SOS (Symptoms of Stress) in order to confirm construct validity. Based on the result, the following is suggested; 1. The modified SESS needs to be reverified with elder. 2. Korean elder's health promotion can be made by development of stress intervention which was accurately measured with SESS.

The incidence of conjoined twins is so rare that few anesthesiologists have an opportunity of managing them. Especially in Korea, there are only a few reports describing the anesthetic management for surgical separation of newborn conjoined twins. We experienced the successful anesthetic management for surgical separation of thoraco-xiphopagus conjoined twins without any particular problems. After applying the noninvasive monitors (ECG, pulse oximeter), one of the twins (twinA) with congenital heart disease was administered with intravenous ketamine for induction of anesthesia and intubated without neuromuscular blocker. Anesthesia was maintained with N2O-O2 and hand ventilation using Mapleson D breathing circuit. After maintaining airway of the twinA, the twinB was intubated and maintained with the same manner. Eighteen days after the separation procedure, the twinA with congenital heart disease died and the other one, twinB has been alive with normal growth and development.
