With the paradigm shifts towards consumer-centered health service, it is expected that more health care consumers will keep their health information and manage their own health in the future. Thus, this study was conducted to compare "Understanding", "Utilization" and "Management" of Personal Health Record(PHR) between medical users(healthcare students) and health care providers(medical students). We collected data from 208 health and medical students via using self-reported questionnaires form April to June, 2011. The collected data were analyzed using frequency, t-test, Chi-square on SPSS 19.0 version. There was no significant difference in "Understanding" of PHR between two groups. Looking at the order of the importance of PHR contents, two groups equally emphasized medical records, surgical history, and test results. There was significant difference in both time and effectiveness of PHR(p=0.02). Intergrated type of PHR was preferred by both groups. Recently, PHR reflects needs and demands of users more than ever. However there are many limitations to promote the utilization. In the future, it is necessary to implement targeted strategies for the elderly groups and specific types of disease.

Objectives: This study is to identify the effect of detraining on lipoprotein and body composition after 8 week calorie restriction and different level of aerobic exercise among obese middle-aged women. Methods: The 30 middle-aged women whose body fat were over 30% were randomly allocated into three groups of control, exercise group of 40% $VO_2$max level, and exercise group of 60% $VO_2$max level. All the participants were taught to record their calorie intake and restrict daily 500kcal intake. After eight-week exercise and daily 500kcal restriction, their body compositions and blood lipid levels were measured again. Results: The weight, BMI, body fat, total cholesterol, triglyceride, and LDL-cholesterol levels showed significant decreases after eight-week exercise and calorie restriction in the two exercise groups. However, detraining tended to increase them again after detraining of 4 weeks, and even more after 8 weeks. Conclusions: Detrainging after calorie restriction and exercise tended to increase levels of indices for body composition and lipoprotein among obese middle-aged women.

The purpose of this study was to analyze the change of body temperature and pain by application of Gaussian magnetic for the elderly delayed muscle pain. For the purpose, we selected 15 elderly women(age;$69.47{\pm}1.60$) and conducted repeated experiments. The Gaussian magnetic field area was divided into three areas (1000G, 1500G, 2000G). The applying arbitrarily manufactured magnetic field wristbands changes of body heat and pain before and after wearing Gaussian magnetic were measured and collected data were analyzed using SPSS 19.0. To examine the pre-and post-treatment differences by treatment areas, we conducted paired t-test. Group differences and interaction effects were analyzed using two-way ANOVA and Duncan post hoc tests. The significance level was set to ${\alpha}=.05$. The results are as follows. The change of body heat by the Gaussian magnetic field area showed significant differences in all three groups(P<.05). There were also significant differences in the results of group interactions and in the delayed muscle pain scale between groups(P<.05). The area with the largest difference appeared in the area of 1500G field. The 1000G-1500G Gauss field is considered to be the most ideal magnetic field for body heat and muscle pain changes. In conclusion, the Gaussian magnetic field of 1000G-1500G may affect body temperature and muscle pain in the elderly, and may have a significant impact on the quality of life in old age.

한국산 담수어류의 잉어목, 황어아과(Leuciscinae) 어류 2속 5종의 계통적 유연관계를 구명하기 위하여 mtDNA분석을 실시하였다 6 base를 인지하는 10개의 제한효소를 처리하여 얻어진 강tDNA의 크기는 16.5-17.5 Kb였으며 Bcl I, Bgl I, Bgl II, Hin dIII, Pvu II, Xba I 등은 종간 차이가 뚜렷하였다. 각종의 집단간 mtDNA분화정도는 매우 낮았으나(p=1% 미만) M. oxyephalus의 무주집단과 제주집단은 예리적으로 큰 차이를 보였다(p=5.3%) Moroco속의 종간 분화정도를 비교한 결과 M. oxycephafus와 M. lagowsk서 사이가 평균 f=7.2%로 근면관계가 제일 가까웠고 M. keumkang과 M. semotilus는 타종들과 근연관계가 제일 멀었다. Moroco속과 Phoxinus속간의 평균 유전적 분화정도는 f=13.7%로 현저한 차이를 보였다. Brown 등(1979)의 공식을 이용하여 이들 황어아과 2속 5종의 분화시기를 추정한 결과 이들은 후기 선신세(Pliocene)와 흥적세(Pleistocene) 사이에 분화된 것으로 추정되었으며 이 결과는 동위효소 연구에서 얻어진 결파(Yang and Min, 1989)와 잘 일치한다.

Surveys of elecirophoretic variations in isozymes and proteins encoded by 25 persumtive loci were conducted to estimate the degree of genic variation and to assess species recognition for three species of the Family Gasterosteidae (Pisces) in Korea. The average degree of genic variation of Gasterosteus aculeatus was HD = 0.086, HG = 0.084, and P =36% and it was similar to Pungitius sinensis (HD = 0.080, HG = 0.091, P = 29%). But P.kaibarae was less variable than these species (HD = 0.034; HG = 0.034, P = 13%). The average genetic similarities among the populations in each species of Gasterosteus aculeatus pungitius sinensis and P. kaibarae were S = 0.963, S = 0.953 and S = 0.800 respectively.Yongchon and Kyongiu populations of P. kaibarae were genetically remote from the rest of the conspecific populations (S = 0.690). Chae (1988) also observed morphological differences between them. The value of genetic similariiy coefficients of S = 0.606 between P. sinensis and P. kaibarae is low enough to consider as specific level of genetic difference, but moderate rate of hybridization (44%) between them at a synpatric area of Kangnung indicates that isolating mechanism is incomplete. Therefore it is concluded that P. sinensis and P. kaffarae are semispecitic status. Intergeneric genetic similarities between the genus Gasrerosteus and Pungitius were S = 0.052 and this value is the lowest estimate up to date in freshwater fishes.

The purpose of this study was, base on the observation that the leg movement has effect on muscles around trunk, to provide clinical fundamental data to develop effective abdominal draw-in technique by investigating the effect of abdominal draw-in exercise accompanying leg movement on the thickness of transversus abdominis muscle and trunk control ability in patients with stroke. The subjects were assigned randomly to experimental group I (n=9) on which the abdominal draw-in technique is applied and experimental group II (n=9) on which the abdominal draw-in technique accompanying leg movement is applied. The thickness of transversus abdominis muscle in the affected side and the trunk control ability were measured before and after treatment using ultrasonography and trunk impairment scale. A session of 30 minutes per day were performed four days a week for four weeks and the measured outcomes were analyzed. The in-group comparison showed significant difference both thickness of transversus abdominis muscle during abdominal draw-in technique application (p<0.01) and trunk control ability (p<0.001) between before and after treatment. The significant difference between two groups were observed only in trunk control ability (p<0.05). It was concluded that the abdominal draw-in technique accompanying leg movement is an intervention that has positive effect not only on transversus abdominis muscle but also on tunk control ability by inducing more efficient contraction reaction in muscles around trunk through autonomic pelvic movement caused by leg movement.

This study, to confirm the mediating effect of knee pain on cognitive functions and depression in older adults, and as an interdisciplinary research between the physical and psychological mechanisms, confirmed the identifying group differences by gender, age, and educational attainment of older adults, and aimed to research the improvement of cognitive functions, which is a main factor of dementia's risk prediction. The analysis data was from the 8th Korean Longitudinal Study of Ageing (KLoSA) in 2020, and the research model was verified using Process macro and model #4. The main analysis results are as follows. First, depression partially mediation effect of knee pain on cognitive functions. Second, the mediation effect of depression by gender was significant, but the direct effect in the male older adults group was twice that in the female older adults; the indirect effect did not vary significantly based on gender. Third, the mediating effect of depression by age was relatively greater in the old-old aged group than in the young-old aged one. Fourth, as for the mediating effect of depression according to the classification of educational attainment, the mediating effect was not significant in the group with a college degree or higher education but was significant in the remaining three sub-groups. Based on the results, this study makes implications for the need for active intervention strategies to improve cognitive functions, focusing on group differences by gender, age, and educational attainment in the management of knee pain and depression.

The genetic relationship was examined with PCR-RAPD markers among three scallop species, Chlamys farreri farreri, Patinopecten yessoensis, and Agropecten irradians. Six primers were selected from 60 primers used to compare PCR-RAPD profiles among species. All primers showed distinct RAPD band patterns between the three species. In Chiamys farreri farreri, the morphological characteristics such as shell size and color were considerably different between the two geographical populations. RAPD profile, however, showed that no significant genetic differences were found between the two geographical populations. Polymorphic alleles were observed within a population of each species. Thus, PCR-RAPD markers are useful in identifying scallop species and in understanding scallop population genetic structure.
