Purpose: The purpose of this study was to investigate the relation between perceived health status and health-promoting behaviors in female college students. Method: Data were collected from December 10 to 31. 2007. In 160 female college students, perceived health status was measured using the Medical Outcomes Short-Form Health Survey (SF-36), and health-promoting behaviors using the Health Promoting Lifestyle Profile (HPLP). Results: The major findings of this study were as follows: 1) The mean scores of the level of health promoting behaviors, physical health status, and mental health status were 2.44 (SD=0.39), 51.9 (SD=8.03), and 42.56 (SD=10.77), respectively. 2) Health-promoting behaviors were correlate with physical health status (r=-.361) and mental health status (r=.498). 3) Health-promoting behaviors were significantly associated with allowance and mental health in capability, which explained 28.9% of variance in health-promoting behaviors. Conclusion: The results suggest that it is necessary to strengthen female college students' practice of exercise and responsibility for health in order to improve their health promotion behaviors. Also, the results of this study give useful information for designing interventions and program development for female college students' appropriate health promoting life.

This study investigated the relationship between infants' temperament and mothers' parenting stress. This investigation is done by focusing on the interaction effects between the infants' temperament and maternal factors. A total of 1,120 infants and their mothers from a national sample were selected as subjects for carrying this investigation. The EAS (Emotionality, Activity and Sociality) Temperament Survey for Children: Parental Ratings was used to measure the infants' emotionality temperament, and PSI-SF(Parenting Stress Index-Short Form), KMSS(Kansas Marital Satisfaction Scale) and a survey on socio-demographic variables were used for the maternal factors. Two-way ANOVA revealed that the parenting stress was significantly different according to the infants'emotionality temperament. Most importantly, there were significant interaction effects between the infants' emotionality temperament and maternal factors(education level, employment status and marital satisfaction). The results were discussed in terms of the goodness of fit of the temperament and parenting models.

The nuclear hormone receptor superfamily currently includes approximately equal numbers of conventional receptors and orphan receptors, which do not have known ligands. Here, we review recent progress from this laboratory on three orphans, two of which are moving from orphan to conventional receptor status. Perhaps the most unusual is CAR, which is a constitutive transactivator in the absence of ligands but becomes transcriptionally inactive in the presence of its ligands, which are androgen metabolites. The response of CAR to its ligands is thus opposite to that of the conventional receptor paradigm. RIP14 (also known as FXR) is activated by both all-trans retinoic acid and a synthetic retinoid previously thought to specifically target the retinoic acid receptors (RARs), and thus appears to be a novel retinoid receptor. Finally, SHP is a novel orphan that lacks a DNA binding domain and interacts with a number of other receptor superfamily members. While it generally inhibits its targets, including CAR, the retinoid X receptor (RXR), and the estrogen receptor (ER), it stimulates transactivation by the orphan SF-1.

북극 스발바르의 사면 지형에는 걸리가 발달되어 있다. 이러한 걸리는, 그 성인에는 여러 의견이 있으나, 화성에도 중고위도를 중심으로 다수 분포한다. 화성의 걸리는 2000년대에 들어 비로소 본격적으로 규명되고 있으나, 지형적 특성으로 인한 탐사의 한계로 지구에 분포하는 유사지형을 통한 비교 연구가 일반적이다(Costard, et al. 2007 등). 이 연구에서는 스발바르의 주도 롱이어비엔에서 UAV을 이용하여 획득한 DEM으로 스발바르 걸리를 측량하고, 이를 화성 중위도의 테라 사이메리아, 테라 시레넘, 노아 키스 테라에 분포하는 걸리와 비교하였다. Longyearbreen 빙하 전방에 위치한 사면을 UAV로 촬영하고, 이를 SfM-MVS(Structure from Motion & MultiView Stereo) 기법으로 3차원 점군 모델과 고해상도 DEM을 제작하여 분석하였다. 화성의 경우 MRO궤도 탐사선이 촬영한 HiRise DTM을 이용하여 분석하였다. 두 걸리는 기후와 지질 조건에 차이가 있음에도 불구하고 유사한 패턴을 보였다. 특히 테라 사이메리아에 위치한 걸리와 롱이어비엔 북사면의 걸리는 기준거리, 단면적, 폭, 경사, 제방 두께 등에서 상당한 정량적 유사관계가 있었다. 이는 두 행성의 걸리가 유사한 성인 및 형성 프로세스를 거쳤을 가능성을 시사한다. 측량 기법과 UAV 의 안정성을 개선시키면 지형 모델의 품질 향상 및 극지에서의 UAV 운용이 용이해질 것으로 기대된다. 또한 스발바르의 기후 요소 및 물리량 적용은 향후 화성 지형연구에도 응용할 수 있을 것으로 사료된다.

This study was carried out to investigate the protective effect of Red Ginseng Saponins on 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) induced toxicities in guinea pigs ($200{\pm}10$ g). Normal control (NC) group guinea pigs ($200{\pm}10$ g) received vehicle and saline, while the TCDD-treated (TT) group was given water-extract (WE), saponin fraction (SF) and non-saponin fraction (NSF). Korean red ginseng fractions were administered from 1 week before TCDD-exposure for 4 weeks. Body weight loss and deteriorated clinical parameters related to sugar metabolism and liver function such as lipase and AST, respectively, these were significantly reduced by both saponin and non-saponin fractions. However, increase of lipase was attenuated by the saponin fraction in a dose-dependent manner. Only AST was affected by the saponin fraction. The results suggest that saponins are active substances in the Korean red ginseng water extract against TCDD induced toxicities in Guinea pigs.

This experiment was carried out to examine the effects of urea-treated rice straw feeding on the growth performance of crossbred Holstein heifers under different feeding conditions. In the first experiment, the animals were given diets having 2 levels of TDN and CP and 3 levels of crude fiber (22, 30 and 36%) which were formulated with urea-treated rice straw and concentrates. Daily weight gain of heifers was not different between 22% and 30% CF diets, but the reduction of TDN or CP level to 90% of the requirements decreased the weight gain. Fiber content of 36% also reduced the body weight gain. The reduction of TDN significantly reduced DM intake and increased feed conversion ratio. Feed cost per kg weight gain was significantly increased by an increase in CF to 36%. In the second experiment, separate feeding and total mixing feeding were compared. There were no significant differences between the two feeding systems in body weight gain although the possibility of superiority in SF to TMF remained. DM intake was not affected by the feeding system, but 30% CF diet gave higher DM intake. Feed cost per kg weight gain was lower in the 30% CF diet.

In order to investigate the abundance and transboundary fluxes of air pollutants over the Yellow Sea, airborne measurements were made aboard the SF-600 aircraft (Pan-Asia Engineering) in March, 1996. The data presented in this paper are preliminary results and airborne experiment will be carried out until 1999. The vertical profile of relevant meteorological parameters such as temperature, water vapor, wind direction and wind speed were also observed at Taean. Mixing layer height was about 1000~1100m during the flights. The SO$_2$ and NO$_{x}$ concentrations were 3~6 ppb and 5~7 ppb below 1000 m, within 1 ppb and 3~5 ppb at 1000~2000m, respectively. Backward trajectory analyses were also carried out. A mathematical method by Lelieveld et al.(1989) was used to estimate the flux of air pollutants through the planetary boundary layer of Yellow Sea area. Transboundary fluxes were calculated using the measurement results with respect to the pollutants concentration, depth of the planetary boundary layer, wind speed and wind direction. The estimated transboundary flux of SO$_2$through the western boundary of Korea was about 39~42 tons/hour.r.

The purpose of this study was to analyze the effect wool in patients with chronic obstructive pulmonary disease. The study was conducted experimentally on 53 patients with chronic obstructive pulmonary disease attending the chest diseases polyclinic of a hospital located in Erzurum. A randomized selection method was used to categorize patients into two groups; a treatment (n = 27), and a control group (n = 26). Patients in the treatment group (pre-test measurements were taken) wore wool vests for a period of three months, while patients in the control group wore cotton vests (placebo) for the same duration; post-test measurements were taken for both groups at the end of the three-month period. The Medical Outcomes Study Short Form 36, the St. George's Respiratory Questionnaire, and pulmonary function tests were used to collect data. Results concluded that there was a significant decrease (p < 0.05) in the overall score of the St. George's Respiratory Questionnaire, and the symptom, effect, and activity mean scores, while there was a significant increase (p < 0.05) in the SF-36 physical functioning, general health, bodily pain, role physical, vitality, role emotional, social functioning, mental health, physical and mental component summary mean scores of patients in the treatment group. Results of the study concluded that the symptoms, activity, disease effectiveness, and quality of life improved in patients that wore wool vests.

Objective : The low back pain was the main reason of receiving acupuncture treatment. Despite its widespread prevalence, objective data assessing the pain and the results of various forms of treatment were difficult to find in korea. In order to compare the value of different types of treatment, it was necessary to use standard and meaningful forms of assessment. Methods : Pain and functional disability scales for low back pain were reviewed for contents, measurement properties and current methodological issues. Results and Conclusions : 1. The SF-36 Bodily Pain Scale and the Graded Chronic Pain Scale were commonly used for the standard pain scale. 2. The Oswestry Disability Questionnaire and the Roland-Morris Disability Questionnaire were commonly used for the standard function scale. 3. When evaluated, there was no definite answer to the results of the treatment. In the literature, the responsiveness of the Roland-Morris Disability Questionnaire ranged from 2 to 8 points but clinically, the ranges should be minimally changed from 2 to 3 points. 4. In the future, scale for low back pain should be standardized in multiple dimension so that the computerized adaptive testing by Item Response Theory could be widely used.

현재 사용되고 있는 진동감쇠능 Mg-Zr 합금인 K1A는 우수한 진동감쇠능을 갖으나 열악한 기계적 특성과 Zr이 고가이면서 고융점 원소로 합금화가 어렵다는 문제점 때문에 진동테이블, 미사일 유도시스템 및 레코딩 장비 등에 소량만 적용되고 있다. Mg-Ni 합금의 경우Ni가 Mg 용탕 내에 고용되지 않아 우수한 진동감쇠능을 갖으나 Fe, Cu등과 함께 Mg의 부식을 가속시키는 원소로 사용이 제한적일 뿐 아니라 Zr과 마찬가지로 Ni도 고융점 원소로 합금화가 어렵다는 것도 문제점으로 작용하고 있다. Mg-Si 합금의 경우 Si이 극소량만 고용되어 우수한 진동감쇠능을 보이며 Ni과 달리 부식에 영향을 받지 않는 원소이지만 Zr, Ni와 마찬가지로 고가이면서 고융점 원소로 합금화가 어렵다는 문제점이 있다. Mg 용탕에 첨가하게 되면 용탕의 표면에 MgO, CaO 피막을 형성하여 발화현상을 억제할 뿐 아리라 첨가량의 증가에 따라 발화온도를 상승시키는 Ca의 경우 Mg 내에 고용되어 진동감쇠능을 감소시킬 뿐 아니라 유동성 저하 및 열간균열을 야기하는 것으로 나타났다. 그러나 CaO의 경우 Mg내에 고용되지 않고, 가격이 저렴하며 Mg 고유 특성의 변화가 적다. 또한 Ca와 같이 Mg 용탕의 발화를 억제하여 보호가스인 $SF_6$를 사용하지 않아도 된다. 이런 다양한 장점을 갖는 CaO를 첨가한 Mg합금이 진동감쇠능을 유지하면서 기계적 특성이 향상된다면 주행 시 안전성 및 정음성이 요구되는 수송기기 분야와 외부충격으로부터 데이터 보호가 필수적인 휴대용 전자정보통신기기 분야에서 적용이 증가할 전망이며 이에 따라 이 분야에 대한 지속적인 연구와 투자가 이루어져야 할 것이다.
