Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

목 적 : 산후우울증의 발생은 출산 직후부터 1년까지 지속될 수 있고 출산 이후에도 오랜 기간동안 발생 가능성이 있으며, 산후우울증을 단순히 선행하는 감정적 문제, 통제 소재, 사회적지지, 출산과 동반된 생리적 변인만으로 설명할 수 없다. 그러므로 산후우울증은 출산후 산모-영아 상호관계에서 겪게되는 어려운 영아의 기질, 산모가 영아를 양육하면서 겪게되는 양육 스트레스, 그리고 산모의 대처 방식과 연관이 있을 것이다. 본 연구는 산후우울증과 영아 기질, 양육 스트레스, 대처방식을 변인으로 하여 산후우울증과의 연관성을 평가하기위해 산후의 우울성향과 각 변인의 관계를 연구하였다. 방 법 : 연구의 대상은 1996년 7월 16일부터 8월 27일까지 인제 대학교 의과대학 부속 상계백병원 소아과 외래에 예방 접종을 위해 내원한 4개월에서 12개월 사이의 영아를 둔 산모 105명을 대상으로 하였다. Beck우울척도(BDI), 영아기질척도(EAS), 부모 양육스트레스 목록표(PSI), 대처방식척도(WCC)를 사용하여 산후의 우울성향과 이들 변인과의 연관성을 평가하여 다음과 같은 결과를 얻었다. 결 과 : 1) 어머니의 우울성향 점수는 영아의 기질중 부정적 정서성(r=.26 p<0.05), 과도한 활동성(r=.22 p<0.05)과 유의미한 상관 관계를 보였다. 영아의 사회성 척도와는 부적 상관이 있었으나 통계적으로 유의미하지는 않았다. 2) 어머니의 우울성향 점수는 양육 스트레스와는 정적 상관관계가 있었다(r=.44 p<0.001). 3) 어머니의 우울성향 점수와 대처방식과 유의미한 상관관계를 보이지 않았다. 4) 영아의 부정적 정서성과 양육 스트레스는 정적 상관관계가 있었으나(r=.49 p<0.001) 사회성, 활동성과의 상관관계는 유의미하지 않았다. 양육 스트레스와 대처방식과도 통계적으로 유의미한 상관관계를 보이지 않았다. 결 론 : 본 연구 결과, 산모의 산후 우울성향과 첫째, 영아 기질 중 정서성과 활동성이 연관관계가 있고 둘째, 양육스트레스와 연관이 있으나 세째, 대처방식과는 연관이 없었다. 이런 결과는 산후의 우울성향과 각 요인과의 연관성을 살펴볼 때 산후우울증에 더 중요한 영향을 미치는 것은 산모의 대처 방식이라는 어머니 측의 변인보다는 출산과 동반된 양육 스트레스 혹은 영아의 어려운 기질일 것이라고 추론할 수 있다. Objectives : This Study examined the relationship of depressive tendency in postpartum women with psychosocial factors such as infant temperament, parental stress and coping style. Methods : The subjects consisted of 05 postpartum women, each of whom had an infant aged 4 to 12 months. They were assessed on demographic variables and on measures of the depressive symptomatology, infant temperament, parental stress and the coping style using Beck Depression Inventory(BDI), the EAS temperamental survey, Parenting Stress Index(PSI), the Way of Coping Checklist(WCC). And then we assessed the relationship of depressive tendency in postpartum women with psychosocial factors. Results : The results were as follows : 1) Depressive tendency in postpartum women had significant relationship with emotionality(r=.26 p<0.05) and activity(r=.22 p<0.05) of infant temperament. 2) Depressive tendency in postpartum women had significant relationship with parenting stress(r=.44 p<0.001). 3) Depressive tendency in postpartum women had no significant relationship with coping style. 4) Parental stress had significant relationship with emotionality(r=.49 p<0.001) but did not have any relationship with sociability and activity of infant temperament. Parenting stress had no significant relationship with coping style. Conclusion : These results suggest that depressive tendency in postpartum women correlated with emotionality and activity of infant temperament correlated with parenting stress but not correlated with coping style. Infant temperament and parenting stress to child rearing are more significantly correlated with depressive tendency in postpartum women than coping style of postpartum women.

Bioequivalence of two cilostazol tablets, the Pletaal^(R)(Korea Otsuka Pharmaceutical Co., Ltd.) and the Cilozol^(R)(Hanmi Pharmaceutical Co., Ltd.), was evaluated according to the guideline of KFDA, Sixteen normal male volunteers(age 20~29 years old) were divided into two groups and a randomized 22 cross-over study was employed. After two tablets containing 50㎎ of cilostazol were orally administered. blood was taken at predetermined time intervals and the concentration of cilostazol in plasma was determined with an HPLC method using UV detector. The pharmacokinetic parameters(C_(max), T_(max) and AUC_(t)) were calculated and ANOVA was utilized for the statistical analysis of parameters. The results showed that the differences in C_(max), T_(max) and AUC_(t) between two tablets were 4.99%, 1.74% and 7.68%, respectively. The powers(1-β) for C_(max), T_(max) and AUC_(t) were83.92%, 80.12% and 85.03%, respectively. Detectable differences(Δ) and confidence intervals were all less than 20%, and confidence interval of all the parameters were also less than 20% at the significance level(α) of 0.05. All of these parameters met the criteria of KFDA for bioequivalence, indicating that Cilozol^(R) tablet is bioequivalent to Pletaal^(R) tablet.

This research aims to prove that relaxation practice that includes abdominal breathing and progressive relaxation is an effective method in lowering the blood pressure by comparing·approving the effect on state anxiety and the blood pressure, which was proceed to divide middle-aged women into relaxation practiced group, aerobic trained group and controlled group randomly and to compare each group and the period of measurement with the data of state anxiety and blood pressure were measured before the test, during the test and after the test under rest from the program was performed for 4 weeks. The research was carried out from Aug. 05 to Sep. 06, 2002 with the measurement that includes the test of 2 times of high pressure under rest for one week to the subject of 21 persons of woman hypertensives from forties to sixties who reside in Busan and then, with the instruction of abdominal breathing and progressive relaxation 2 times a week to the relaxation practiced group, the instruction of aerobic exercise 3 times a week for 4 weeks to aerobic trained group and non-instruction to controlled group. 2 weeks after the test, state anxiety and blood pressure were measured and post investigation was made after then. For the process of data using SPSS Program 10.0, repeated measure ANOVA was used at significant level p=.05 in the comparison of each group and the change of relevant variable, one-way ANOVA was used in the analysis of the period of the test among each group and multiple comparison by Tukey test was made in the post approval. From this process of date, the following conclusion was drawn. First, state anxiety of relaxation practiced group was decreased significantly in comparison to that of aerobic trained group and controlled group. Second, the systolic blood pressure of relaxation practiced group was decreased significantly in comparison to that of aerobic trained group and controlled group. Third, the diastolic blood pressure of relaxation practiced group was decreased steadily in comparison to that of aerobic trained group and controlled group, but statistical significant decrease was not found Consequently, its been proved that the relaxation practice which consists of abdominal breathing and progressive relaxation didn't affect on the diastolic blood pressure but did affect on the control of state anxiety and the systolic blood pressure.

The characteristics of ichthyofauna and fish community in the Lagoon Gyeongpo, Korea were investigated from May to October 2005. The total number of fish caught during the period was representing 26 specis and 18 families. Most dominant species was T. hakonensis(50.65%) and subdominant specis was A. flavimaus(25.41%). K. punctatatus(11.07%), M. cephalus(6.53%), E. japonicus(1.46%), C. castaneus(1.01%) were also numerous. The total biomass of collected fish showed 147.00kg, 135.83kg, 85.60kg,23.76kg, repectively. A pattern of the fish community according to seasonal veriations appear to be related tp spawning periods of species. Comparison of the ichthyofauna in present study with the references from early years suggests that there has been a gradual decrease, in composition, of primary freshwater specis accompanying with the increase of peripheral freshwater and seawater specis.
