Hormone replacement therapy combined with progestogens induces changes in effect of estrogen on serum lipid levels and it has been known that the changes depend on a type and dosage of progestogen. It is also known that progestational agent induces positive ch-ange in bone mineral density. To study the effects of progestogen on lipoprotein and bone metabolism, we administ- ered conjugated equine estrogen 0.625 mg alone to 50 postmenopausal women, in combinat- ion with medroxy- progesterone acetate 5 mg to 40 postmenopausal women. The data demonstrated a beneficial effect in lipoprotein profiles in both groups. Total cholesterol in two groups decreased from the baseline values, LDL-cholesterol decreased significantly by 4.8 % in group I and 16.2 % in group II(p < 0.05), HDL-cholesterol increa- sed significantly by 11.3 % in group I and 14.7 % in group II(p < 0.05), triglyceride incre- ased slightly in both groups. Bone mineral density of femur was maintained and BMD of vertebrae increased by 1.1 % in group I and 2.0 % in group II, but it is not statistically significant. The differences of changes between two groups were not statistically significa- nt. Our results suggest that medroxyprogesterone acetate have no adverse effect on HDL -cholesterol and have no additive effect on bone mineral density in hormone replacement therapy.

OBJECTIVES: The 2nd to 4th digit length ratio(2D : 4D) is a sexually dimorphic trait regardless of ethnicity and shows sex differences. According to previous research, men usually have a relatively shorter 2nd digit than 4th digit. There is tendency that men with lower 2D : 4D are perceived as being more masculine and tend to perform better in some physical sports. Furthermore, 2D : 4D is negatively associated with trait aggression. In this study, we examine gender difference of 2D : 4D and compare 2D : 4D of female Korean national team members to 2D : 4D of control subjects. Besides that, we also compare 2D : 4D of female Korean national team members according to their sports entries. METHODS: The sample of this study is 396 people, 67 female Korean national team member, 216 control women and 113 control men. We measured 2nd to 4th digit length of their right hand. In addition, we collected demographic information of female Korean national team members using a self-report questionnaire. RESULTS: The mean 2D : 4D of female Korean national team members is 0.96(SD=0.04), smaller than control women's 2D : 4D(0.97, SD=0.03) and significantly higher than control men's 2D : 4D(0.95, SD=0.03). We also found differences between control men and women. Non-martial arts related sports athletes have significant difference with control men in 2D : 4D. However, martial arts related sports athletes' 2D : 4D is not significantly different from other groups, including control men. CONCLUSION: These results are consistent with the findings of previous research that there is a significant difference between men and women in their 2D : 4D. Furthermore, 2D : 4D of martial arts related sports athletes have not shown any difference from the 2D : 4D of control men that 2D : 4D of non-martial arts related athletes have shown. This fact is important in consideration of masculine characteristics. For further research, it is necessary to examine 2D : 4D difference according to sport ability and gender differences.

A case of Aicardi syndrome with cleft lip and palate was experienced at the Department of Pediatrics, College of Medicine, Hallym University, and the patient's infantile spasm was treated with ACTH. In previous studies, four cases of Aicardi syndrome accompanied by cleft lip and palate were reported. We present the fifth case of Aicardi syndrome with cleft lip and palate in the world. Thus, facial clefts may be found as an occasional manifestation of Aicardi syndrome.

Upper extremity replantation is relatively less commonly performed than finger or hand replantation. We have experienced one case of forearm replantation and one case of upper arm replantation. After the replantation, limb volume at the biceps brachii muscle level below the replantation level appeared to be appropriate, however, the motor function of the muscles and the sensitivity were disappointing. For replantation of forearm and upper arm, restoration of the motor function and sensitivity of the extremity below the amputation level as well as the morphologic reconstruction have to be considered.

Pneumoconiosis is one of the most important occupational disease in Korea. In Pusan, most of pneumoconiosis is welders' pneumoconiosis developed in shipyard. With clinical (including interview with every patients) and radiological (chest radiographs) methods, author purposed to know the factors related to development of pneumoconiosis in shipyard welders and to apply the results to the concept for health care (management) of shipyard welders. The prevalence rate of welders' pneumoconiosis was calculated by the means of reading of chest radiographs of 547 shipyard welders. The prevalence rate of welders' pneumoconiosis (including suspected pneumoconiosis, category 0/1) was 7.9%. It was lower than that (8.9%) in same area studied in 1989. Prevalence rate increased as total welding duration increased and the welding work began early. It was higher in welders who did not use antidust mask. Probability of the occurance of welder's pneumoconiosis was related with the time that the welder began welding work. Sixteen cases among the 37 who were diagnosed as pneumoconiosis returned normal in the follow-up chest radiographs. There was no case aggrevated. The pertinent management for the personnels and their working environment contributed to the decrease of incidence of the welders' pneumoconiosis and the improvement of the disease. To prevent the occurance of the pneumoconiosis in shipyard welders, it seems to be necessary for the company to be supervised under the any legislation and to educate the welder to use the protective apparatus. It is suggested that considerate and continuous observation under the adequate management is preferable to the immediate conversion of the working department for the pneumoconiotic welders.

Anaplasma species are obligate intracellular pathogens that can cause tick-borne diseases in mammalian hosts. To date, very few studies of their occurrence in Korean native goats (Capra aegagrus hircus) have been reported. In the present study, we investigated Anaplasma infection of Korean native goats on Jeju Island, Republic of Korea, and performed phylogenetic analysis based on the 16S rRNA gene sequences. Our results showed that Anaplasma infection was found mostly in adult female goats. The phylogenetic tree revealed that the 7 sequences identified in Korean native goats could belong to Anaplasma sp. and were distinct from A. marginale, A. centrale, and A. ovis. The results indicated that the sequences identified to belong to Anaplasma were closely related to sequences isolated from goats in China and were clustered within the same group. To our knowledge, this is the first study to detect Anaplasma sp. infection in Korean native goats.

PURPOSE: Nursing is regarded as a female-dominated profession. However, the number of Korean males entering the field of nursing is increasing. This study examines which of the following factors influence professionalism in male and female student nurses: area of nursing, gender identity, gender stereotypes, satisfaction with the field, emotional intelligence, and interpersonal relationships. METHODS: In total, 133 male and 293 female student nurses were selected from four Korean provinces between July 2013 and February 2014 to participate in this study. The data were analyzed with descriptive statistics, t-tests, chi2-tests of independence, and multiple regression analyses using SPSS/Win 20 software. RESULTS: In males, 47.4% of variance in nursing professionalism was accounted for by grades, interpersonal relationships, gender stereotypes, and satisfaction with the field. In females, 41.9% of variance in nursing professionalism was accounted for by satisfaction with the field, interpersonal relationships, area of nursing, age, emotional intelligence and grades. Common factors that influenced both genders included satisfaction with the field, interpersonal relationships and grades. CONCLUSION: Although males and females revealed no significant differences in overall mean scores of nursing professionalism, several factors influencing nursing professionalism did differ by gender. Therefore, gender-specific nursing educational and training programs may be necessary to promote professionalism among student nurses.

OBJECTIVE: To gain basic information regarding the biologic stability of plasma ion-implanted miniscrews and their potential clinical applications. METHODS: Sixteen plasma ion-implanted and 16 sandblasted and acid-etched (SLA) miniscrews were bilaterally inserted in the mandibles of 4 beagles (2 miniscrews of each type per quadrant). Then, 250 - 300 gm of force from Ni-Ti coil springs was applied for 2 different periods: 12 weeks on one side and 3 weeks contralaterally. Thereafter, the animals were sacrificed and mandibular specimens including the miniscrews were collected. The insertion torque and mobility were compared between the groups. The bone-implant contact and bone volume ratio were calculated within 800 microm of the miniscrews and compared between the loading periods. The number of osteoblasts was also quantified. The measurements were expressed as percentages and analyzed by independent t-tests (p < 0.05). RESULTS: No significant differences in any of the analyzed parameters were noted between the groups. CONCLUSIONS: The preliminary findings indicate that plasma ion-implanted miniscrews have similar biologic characteristics to SLA miniscrews in terms of insertion torque, mobility, bone-implant contact rate, and bone volume rate.
