Pinic acid (PA) and cis-pinonic acid (CPA) in the atmospheric particulate matter with an aerodynamic diameter of less than or equal to a nominal $10{\mu}m$ ($PM_{10}$) were analyzed for the samples collected during the period of April 2010 to April 2011 at Jongro in Seoul. Both pinic acid and cis-pinonic acid showed higher seasonal average concentrations in summer (PA; $18.9ng/m^3$, CPA; $16.0ng/m^3$) than winter (PA; $5.3ng/m^3$, CPA; $5.9ng/m^3$). They displayed a seasonal pattern associated with temperature reflecting the influence on emissions of ${\alpha}-pinene$ and ${\beta}-pinene$ from conifers and their photochemical reaction. These results were confirmed through Pearson correlation coefficient between CPA, PA and $O_3+NO_2$, temperature. CPA was only correlated with n-alkanes ($C_{29}$, $C_{31}$, $C_{33}$) from biogenic source. PA was correlated with n-alkanes ($C_{29}$, $C_{31}$, $C_{33}$), n-alkanoic acid ($C_{20}$, $C_{22}$, $C_{24}$) from biogenic source and n-alkanes ($C_{28}$, $C_{30}$, $C_{32}$), and n-alkanoic acid ($C_{16}$, $C_{18}$) from anthropogenic source. These results showed that the formation of PA and CPA from ${\alpha}-pinene$ and ${\beta}-pinene$ is related to organic compounds from biogenic source. And it is possible for PA to be effected by organic compounds from anthropogenic source.

Angelicae Koreanae Radix has been used for controlling inflammatory respiratory diseases in folk medicine and their components, imperatorin, marmesinin and oxypeucedanin were reported to have diverse biological effects. In this study, we investigated whether imperatorin, marmesinin and oxypeucedanin affect adenosine triphosphate(ATP)-induced mucin secretion from cultured airway epithelial cells. Confluent primary hamster tracheal surface epithelial(HTSE) cells were metabolically radiolabeled using $^3H$-glucosamine for 24 h and chased for 30 min in the presence of varying concentrations of each agent to assess the effects on $^3H$-mucin secretion. The results were as follows: 1) imperatorin significantly inhibited ATP-induced mucin secretion; 2) However, marmesinin and oxypeucedanin did not affect ATP-induced mucin secretion, significantly. We conclude that imperatorin might inhibit ATP-induced mucin secretion by directly acting on airway mucin-secreting cells. Therefore, imperatorin should further be investigated for the possible use as mucoregulators in the treatment of inflammatory airway diseases.

The Purpose of this study was to grasp the status of drug uses in college students, and to investigate the knowledge and attitude when they use it. We collected through questionnaires from Sep. 1 to Oct. 30 in 1999. The subjects were 490 college students in Seoul and northern of the Kyunggi-do. The data analysis was performed using SPSS (version 7.0) and ANOVA. The results of this study were as follows. 1. There was no correlation for all factors in the relationship between general characteristics of subjects and knowledge for drugs. On the contrary, in the relation of the general characteristics and attitude for drug of subjects, some factors are statistically significant e.g., department (F=3.049, p<.010), satisfaction for school life (F=6.167,p<.002), body shape(F=8.092, p<.000), and the relationship with ones parents (F=3.728, p<.005). 2. In the analysis of drug use status and knowledge, only in the factor of administration control was statistically significant(F=4.304, p<.014) and in the relation of attitude for drug uses, drug administration was statistically significant (F=4.521, p<.004). 3. In the mean scores for the drug knowledge analysis, the highest factor was 'A narcotic make deformed persons through poisoning of physical and mental' (M=4.14), the lowest factor was 'If catch the flu during the pregnancy, should be take drug as possible as quickly to reduce negative effect for fetal' (M=1.94). 4. In the analysis for drug attitude, the highest factor was 'A drug is alike a poison' (M=3.48), 'Should be keep the usage and dosage of drug' was the lowest (M=1.48). 5. From the investigation for status of drug use, it was revealed that the most subjects (73.6%) were purchase drugs after explain their symptoms to pharmacist. And they take drugs only when they felt painful in 43.1%. The most students (70.4%) were experienced control of drug administration. It was inquired that subjects were mainly obtained information about drugs from pharmacist and television (or radio) advertisement, 33.5% and 33.1%, respectively. In the examination for existence of long-term administrators in their family, 'none' and 'only parents' are 49.6% and 37.3%, respectively. When their parents have illness, the persons go to drugstore and hospital for heath-care, 47.8% and 44.3%, respectively. On the basis of results of this study, we suggest as follows. 1. This study was analyzed data from questionnaires for college students in a part of local areas, so we suggest that the next research should be perform for national-wide students as subjects to generalize the results. 2. It is need more intensive research methodologies such as interview and observation. 3. Additional research is required for knowledge and behaviors of drug uses that will how impact on ones health behavior.

본 연구에서는 전호추출물의 주름개선에 대한 효능을 측정하기 위하여 인간의 섬유아세포에 전호추출물을 처리하여 총콜라겐과 type I procollagen, MMP-1의 생합성에 미치는 영향을 조사하였다. 전호추출물을 인간 섬유아세포에 처리 시 콜라겐의 생합성은 증가시켰지만, MMP-1의 발현에 대해서는 영향을 미치지 못하였다. 이는 전호추출물이 자외선에 의해 영향을 받는 광노화보다는, 노화에 의해 콜라겐 생합성율이 감소되는 내인성노화에 훨씬 유효함을 시사한다. 전호추출물을 처리시 95% EtOH 추출물의 경우 25%까지 총콜라겐의 생합성을 증가시켰고, EtOAc층은 28%, EtOAc의 E6 소분획의 경우 50% 증가시켰으므로, 콜라겐 생합성에 영향을 미치는 유효성분은 EtOAc층에 대부분 함유되어 있을 것으로 사료되고, 이는 확인되지 않은 미지의 효능 성분이 존재하거나, 다양한 활성 성분들의 상호 작용에 의한 것으로 판단된다. 결론적으로 전호추출물은 콜라겐 생합성을 촉진함으로 내인성노화에 의한 주름생성 및 탄력저하를 개선할 수 있는 천연 유용자원으로 이용할 수 있을 것으로 사료된다.

Objectives: This study examined the characteristics and nutritional risk of the elderly who receive home delivery services. We then analyzed the effects of the characteristics of the elderly who receive the home-delivery meal service on their nutritional risk. Methods: A total of 220 respondents who receive home-delivery meal service in Seoul participated in the survey. The survey consisted of the characteristics of the elderly (health status, tooth condition, physical activity, social participation activity, depression and relationship with neighbors), nutritional risk assessment and other general matters. The data was analyzed by using the SPSS program. Cross-tabulation analysis, t-test, correlation analysis and regression analysis were all conducted. Results: 47.0% of the subjects were under 80 years old and 53.0% were over 80 years old, The nutritional risk score, as evaluated by a Nutrition Screening Initiative (NSI) checklist was 10.7 points, and the high nutrition risk group was 91.5% of the subjects. The subjective self-health status score was 2.24 points (out of a total of 5 points) and the tooth status score was 3.30 points. The physical activity level was 2.17 points for the under 80 years old group and 1.76 points for the over 80 years old, and there was a significant difference according to age (p<0.01), The higher the health status, tooth condition, physical activity and social participation activity level, the lower was the nutritional risk. Further, the higher the degree of depression, the higher was the nutritional risk. Conclusions: For the healthy life of the elderly in the community, various welfare policies should be planned to increase social participation as well as to promote physical health and reduce depression.

Purpose : This study aimed to introduce a 12-week muscular endurance exercise program and β-glucan consumption to obese elderly people with sarcopenia. We evaluated the program's impact on appendicular skeletal muscle strength and function, muscle function-related physical strength, blood lipids, and IGF-1. The results will serve as foundational data for preventing and improving sarcopenia. Methods : Forty elderly people aged 65 or older were recruited and underwent dual-energy X-ray absorptiometry. Based on criteria related to appendicular skeletal muscle mass (ASM/Height2: less than 5.4 kg/m2) and body fat percentage (at least 30% for women and 25% for men), we selected 24 obese elderly people with sarcopenia and excluded 56 who did not meet the criteria. Variables related to sarcopenia, blood lipids, IGF-1, and muscle function were measured before the 12-week muscular endurance exercise program. Results : In sarcopenic obese elderly participants, the 12-week muscular endurance exercise program significantly increased bone density and muscle mass while decreasing fat mass and percentage (p<.05). This program also improved grip strength, static balance, and SPPB in sarcopenic obese older adults. Furthermore, their 6-minute walk distance significantly increased (p<.05). Conclusion : Muscular endurance exercises combined with supplement intake can increase appendicular skeletal muscle and improve muscle strength and function, thereby improving the daily physical performance of the elderly.

It is utmostly important to establish the efficient fitable way of peoples' active participation in primary health care especially in the areas where the public or governmental service input for the basic health care is insufficient like as in rural areas of Korea. In light of above reason, this study focused mainly on the evaluation of roles and activities of village health workers (VHWs) who were selected from grass- root level of village people in order to derive further motivation for active participation. This is believed to be a sort of feedback mechanisms. Actually, the authors collected the activity reports of VHWs who had been devoting themselves in the primary health care services of Jeomdong Area, of Yeoju Gun one of Korea University Community Health Action Programmes and survey record on the VHWs activity from correspondent people. 1 hose data were analyzed through computer programmed package. The activities performed by VHWs were limited to the performance in 1985 for conveniance. The summarized results were as follows; 1) General characteristics of VHWs. Among a total of 28 VHWs in the area, about 39.3g of them have been replaced up to the date since the implementation in 1983, because of moving out, occupational employment and of others. The age of majority (75.0%) lied between the range of 30-50, and educational background of 67.9% belonged to category of primary school graduation, about 50% of them experienced to be or were also entiled "chief of women club" of corresponding villages. 2) Work-load of VHWs. Each VHW was assigned for tasks of health care for average 55 households of 248 persons. They shared approximately 6 days a month for the activity in average and it covered 17 cases of basic health care in a month. A half of the VHWs performed home visits irregularly without solidified schedule. 3) Work performance analysis. Informations collected through VHWs were compared with data from official vital registration at local administration center "Myon Office" in 1985. VHWs collected 100.8 of new born, 116.2 of death, 58.3 of move in and 74.8 of move out in comparison with 100.0 of official registration each. Pregnant women of 79.8% of mothers among the total pregnancy of 94 which were confirmed as normally delivered or aborted cases by all means afterwards had been detected by VHWs as being pregnant and all of them received some of antenatal cares by VHWs. All(100%) of delivered women were detected by VHWs through home visits and they were cared postnatally. Whereas, according to the records of birth registration, the places of delivery were clinic in 33.7%, and mother's home in 66.3%, VHWs reported them to be clinic in 48.9%, midwifery in 20.2%. It was cleared that most of misinformation was caused by uncautious filling of birth registration at notification. Among the total of 717 eligible women under age 44 years, family planning status of 92.6% was reported by VHWs confirming practice of control to be 70.8% of reported fertile women. 4) Attitude of VHW on the roles and functions. Although 92.0% of VHWs expressed VHWs to be worthwhile, only 52.0% of them had dignity and satisfaction in their activity and 44.0% of them had passive attitude of working saying they followed direction regardlessly. Concerning difficulties in performance as a VHW, 60.7% of them pointed out lacking of medical and health related knowledge by themselves. Still, 64.0% of them thought visiting unfamilier house to be awful and 40.0% complained forms of activity to be difficult and hard. It was also revealed that 56.6% confessed lack of interest on community health service itself. Most of VHWs needed more educational training especially on clinical fields such as cares of gynecological diseases, hypertension, diabetes, and other chronic diseaes of the aged. Regular on-the-job basic trainings were said to be needed twice a year.
