Purpose: This study was conducted with a focus group interview that drew out experiences, limitations, and difficulties in the workplace according to the employment conditions of visiting nurses in the public health centers. Methods: A total of 12 visiting nurses are those working in the public sector in Seoul and Gyeonggi province who were willing to participate in the interview. Analysis categories and coding were divided into three categories: compensation system, occupational status, and opinions to improve their treatment. Using the content analysis method, the current working status and compensation system of visiting nurses were described. Results: The main themes derived from the significant statements of visiting nurses were 'Ten years of frozen salary system', 'Full-time workers of their own league', 'Excluded from performance benefits', 'Every visiting nurses are virtually precarious', 'Experience of exclusion and discrimination', and 'Reasons and barriers to be a full-time worker'. All of the visiting nurses working in the community insisted on having equal treatment for work of equal value. Visiting nurses in the public health sector wanted to be set to the same payment system and the fair allowance system as well. It is necessary to continuously seek solutions to the problems left in insisting on the civil service of visiting nurses. Conclusion: Visiting nurses who were working in a precarious job position felt job insecurity, and experienced discrimination, alienation, and exclusion. Legal and institutional reform is needed to improve the treatment of visiting nurses.

Purpose: This study was to provide basic information for preventing high school students from smoking by examining their actual smoking condition and their knowledge and attitude about smoking. Method: The subjects were 515 students selected from six(6), high schools in Jecheon. Data were collected using a questionnaire from the 1st to the 17th of December 2002. The author prepared the tool by modifying the scale of knowledge and attitude about smoking developed by Moon(2001). Data were analyzed with SPSS/WIN program using frequencies, percentages, $x^2$-test, t-test, ANOVA. Duncan test and Pearson's correlation coefficient. Result: 1. The percentage of ex-smoking students was 29.9% of male students and 18.6% of female ones. The percentage of currently smoking students was 23.9% of male students and 3.0% of female ones. The percentage of non-smoking students was 46.2% of male students and 78.4% of female ones, 2. There were not significant differences in smoking knowledge according to smoking status in male and female students. 3. There were significant differences in smoking attitude according to smoking status in male(F=32.70, p=.000) and female(F=11.15, p=.000) students. 4. In smoking status according to general characteristics, there were significant differences according to the type of school($x^2$=32.93, p=.000), grade($x^2$=11.91, p=.018), educational level of the father($x^2$=30.52, p=.000) and the mother($x^2$=14.23, p=.027), monthly allowance($x^2$=17.19, p=.028), harmony of family members($x^2$=15.23, p=.019), school life($x^2$=26.96, p=.00l) and school record($x^2$=30.24, p=.000). 5. In smoking status according to smoking-related characteristics, there were significant differences according to experience in cigarette purchase($x^2$=150.04. p=.000), experience in errands for cigarette($x^2$=20.00, p=.000), knowledge of cigarette price($x^2$=72.52, p=.000), close friends' smoking($x^2$=107.41. p=.000) and smoking of brothers and sisters($x^2$=16.97, p=.002). 6. There were significant correlation between knowledge and attitude about smoking in the whole students(r=.337. p=.000), ex-smokers(r=.324. p=.000), non-smokers(r=.369. p=.000) but there was not a significant correlation between knowledge and attitude about smoking in current smokers(r=.128. p=.30l). Conclusion: Smoking prevention education should considered students' smoking status. Current smokers need smoking prevention education aiming to change their attitude toward smoking in order for them to reduce smoking and to practice smoking cessation.

Purpose: This study conducted a survey on the elderly of 65 years and over with physical debilities and ones capable of living at home residing in Jeju Special Self-Government Province to compare and analyze demo-sociological characteristics and factors influencing on oral health related living quality. And also this study intended to provide basic data for developing effective public medical policies and health promotion programs to increase oral health related living quality of the elder. Methods: The elderly of 65 years and over living in Jeju Special Self-Government Province were interviewed individually from 7 February 2011 to 18 April and interview results of a total of 220 subjects were analysed for this study. Results: Current status of the elderly including ones with & without physical debilities influenced functional limitation and behavioral aspects of GOHAI criteria used in this study. The elderly with physical debilities experienced less limitation in food chewing and swallowing, and pronunciation than ones capable of living at home. On the analogy of the previous study(by Park, N. G., 2010) in which oral health related quality and satisfaction of life of the elderly with physical debilities were different due to their physical, circumstantial and psychological limitations, the former's oral health conditions are worse than the ones capable of living at home and because of medical care accessability limitation they suffer from deteriorated oral condition. By the comparison of factors influencing on the living quality relating to the oral health of the elderly with physical debilities and ones capable of living at home, 2 factors, age and living area, were meaningful factors commonly influencing on the oral health related living qualities of both. The elderly of 75 years and over were more affected by psychological and behavioral aspects of oral health related living quality than the ones of 65-74 years, and the ones living in country suffered from functional limitations, pains and discomfort more than ones in city. Additionally, being different from the elderly capable of living at home, the ones with physical debilities were influenced by the factors of average monthly income and medical security type. Conclusion: Improvement of programs and systems to increase oral health related quality of life needs to be carried out preferentially for the elderly of 75 years and over, and dwelling in country. Also this study suggests that the policy of paying the denture insurance allowance in 2012 need effective planning considering the elderly's current status, age, living area, medical security type.

루미네센스(luminescence)는 석영이나 장석 등과 같은 무기결정이 외부에서 에너지를 받아 흡수된 에너지를 빛으로 바꿔 외부에 방출하는 물리적인 현상이다. 가전자대(valence band)에 존재하는 하전입자들은 전리성 방사선에 의해 전자와 정공(hole)으로 이온화 되고, 이온화된 전자와 정공들은 결정 내에서 자유로이 움직이다가 결정 내에 존재하는 격자결함에 포획된다. 이러한 결정을 빛으로 여기하면 격자결함에 포획된 전자들이 결함에서 빠져 나와 발광중심(recombination center)에서 정공과 재결합하면서 빛을 동반하게 되는데, 이를 광 여기 루미네센스(optically stimulated luminescence; OSL)라 한다. 열 루미네센스(thermoluminescence; TL) 연대 측정법의 원리와 같이, 광 여기 루미네센스를 적당한 조건에서 관측하면 퇴적층의 연대 계산에 응용할 수 있다. 광 여기 루미네센스를 연대측정에 이용하면 빛에 민감한 전자들만 여기시킬 수 있는 장점이 있다. 이 연구에서는 신기 퇴적층으로부터 분리된 석영을 청색 파장의 빛으로 여기하여 그로부터 검출된 광 여기 루미네센스를 신기 퇴적층의 연대 산출에 응용하였다. 논문에서는 광 여기 루미네센스 연대측정법과 관련된 일련의 실험방법 및 최근에 소개된 연구성과, 그리고 앞으로 보다 신뢰도 높은 연대측정 결과를 얻기 위해 연구되어야 할 내용을 이 연구에서 수행한 신기 퇴적층의 연대측정 결과와 함께 기술하였다.

The objective of this study was to determine the effect of replacing corn with soy hulls on nutrient digestibility of growing pigs. Three experimental diets were tested using a 3 × 3 Latin square design using three barrows per group (Landrace × Yorkshire × Duroc, average initial body weight of 36.9 ± 4.0 kg) in individual metabolic cages. The dietary treatments were the control (CON) basal diet (corn-soybean meal based diet), whereas in the test diets, soy hulls were included at 5% (H1), 10% (H2), gradually replacing corn. The daily feed allowance was adjusted to 2.7 times the maintenance requirement for digestible energy (DE) (2.7 × 110 kcal of DE/kg BW^0.75). Intake of crude fiber (CF) was different among treatments (p < 0.05). Pigs fed with H2 diet excreted higher concentrations of dry matter (DM), and CF than pigs fed with H1 diet and basal diet (p < 0.05). Pigs fed with H1 and H2 diets excreted higher concentrations of crude protein (CP) than pigs fed with CON diet (p < 0.05). The apparent total tract digestibility (ATTD) of CF from H1 and H2 diets were higher than CON diet (p < 0.05). Pigs fed with H2 diets were significantly lower (p < 0.05) the ATTD of CP than the pigs fed with CON and H1 diets. The current data suggest that 10% inclusion soy hulls can slightly decrease CP digestibility. However, soy hulls considerably increased CF digestibility.It is concluded that 5% soy hulls may be a usable alternative to corn in growing pig diets.

This study was carried out to investigate the effects of stocking density on eating and ruminating behavior of Hanwoo steers (Bos taurus coreanae) in the finishing period. A total of 30 finishing Hanwoo steers ($631.3{\pm}11.4$ kg, 25 months old) were allocated to one of four stocking density groups comprising 1, 2, 3, and 4 steers per 32 $m^2$ pen [G1 (32 $m^2$), G2 (16 $m^2$), G3 (10.7 $m^2$) and G4 (8 $m^2$), respectively] in triplicate. Eating, rumination behaviors, as well as dry matter intake of steers were measured, and the results were subjected to analysis of variance with stocking density as the main effect. The results of eating behaviors over 48 hours are summarized as follows: Total intake was significantly (p<0.01) higher in G1, G2, and G3 compared to G4. Eating time was not different among the treatments, whereas ruminating time increased in the order of G1 > G2 > G3 > G4 (p<0.01). However, resting time and chewing time (sum of eating and ruminating) were not significantly different among the treatments. Number of boluses and number of total chews were highest in G1 (p<0.01), whereas number of chews per bolus was highest in G3 (p<0.01). Ruminating time per bolus as well as number of boluses per minute was not significantly different among the treatments. Number of defecations was higher in G1 and G2 animals compared to G3 and G4 animals (p<0.01). However, stocking density had no effect on drinking or urination. In conclusion, increasing stocking density (i.e. G4) per pen decreased voluntary intake, ruminating time, and total chewing number in the finishing period of Hanwoo steers. However, care must be taken in discussing stocking density in the present study as the space allowance per animal was satisfactory to meet the current animal welfare regulation in Korea and in Europe, although the beef production system in Korea is more intensive than in Europe.

The primary aim of this study was to investigate biosecurity practices in pig farms and to determine the major risk factors associated with PCV2 infection for a sampled swine population in Korea. To this end, we analyzed data from a cross-sectional study of 296 farrow-to-finish farms, which was conducted between March and September 2014 to explore the prevalence of swine disease at farm level. Face-to-face interviews by on-site visit of trained veterinarians were conducted with the farm owners or managers using a standardized questionnaires with information about basic demographical data and management practices. Farms were classified as negative or positive through the use of infection profiles that combined data on serological testing including PCR antigen test result, antibody titer and sero-conversion pattern at each age category taking into account vaccination status. Data were analyzed using multivariate ordinal logistic regression. Results from this study indicated that biosecurity level of the farms was considered not good given low compliance of the biosecurity programs and facilities in the farm: off-site removal of dead stocks (7%), off-site location of storage facility for incoming feeds (12.6%), off-site pick-up location for finishers (19.3%), restrictions on feed supplier vehicles for farm entrance (19.6%), restriction of finisher trucks entering the farm (22.4%), and restriction on manure disposal trucks entering the farm (26.4%). In the final model (n = 255), allowance of finisher truck driver to the pig unit had increased risk of infection (OR = 2.4, 95% CI 1.22-4.67) whereas farms with a sign forbidding the entrance had decreased risk of infection (OR = 0.19, 95% CI 0.10-0.58). Further comprehensive research with larger sample size is required to better understand the multifactorial characteristic that some predisposing risk factors that were not available in this study. To the best knowledge of the authors, this was the first study to use empirical data to report risk factors associated with PCV2 infection in the Korean pig farms. Results from the current study could be used to decide optimal biosecurity measures to reduce the impact of PCV2 infection to farmers and policy makers.

Sarcopenia, a common clinical syndrome in older adults, is defined as decreased muscle mass, strength, and physical performance. Since sarcopenia is associated with the incidence of functional decline, falls, and even mortality in older adults, researchers and health care providers have been keen to accumulate clinical evidence to advocate the screening and prevention of sarcopenia progression in older adults. The factors that may accelerate the loss of muscle mass and function include chronic diseases, inactivity, and deficiency in appropriate nutritional support. Among these, nutritional support is considered an initial step to delay the progression of muscle wasting and improve physical performance in community-dwelling older adults. However, a nationwide study suggested that most Korean older adults do not consume sufficient dietary protein to maintain their muscle mass. Furthermore, considering age-associated anabolic resistance to dietary protein, higher protein intake should be emphasized in older adults than in younger people. To develop a dietary protein recommendation for older adults in Korea, we reviewed the relevant literature, including interventional studies from Korea. From these, we recommend that older adults consume at least 1.2 g of protein per kg of body weight per day (g/kg/day) to delay the progression of muscle wasting. The amount we recommend (1.2 g/kg/day) is 31.4% higher than the previously suggested recommended daily allowance (i.e., 0.91 g/kg/day) for the general population of Korea. Also, evidence to date suggests that the combination of exercise and nutritional support may enhance the beneficial effects of protein intake in older adults in Korea. We found that the current studies are insufficient to build population-based guidelines for older adults, and we call for further researches in Korea.

본 연구는 평면곡선부에서 나타나는 저속 offtracking현상에 대한 이해를 바탕으로 현 한국 확폭량 산정방법 및 확폭 기준량의 문제점을 살펴보고 이를 보완키 위한 새로운 확폭량 산정방법 및 확폭 기준량을 제시하고자 하였다. 이를 위해 저속 offtracking현상에 대한 기존 연구들을 검토하였으며, 유도과정 없이 결과만 제시되어 있는 외국의 확폭량 산정식에 대해서는 명확한 유도 작업을 수행하였다. 현 한국의 도로의 구조·시설 기준에 관한 규clr 해설 및 지침(이하 도로시 설기준령)에서 제시하고 있는 확폭량 산정방법과 외국의 확폭량 산정방법을 비교하였으며, 그 결과 현재 한국 도로시설기준령에서 제시하고 있는 확폭량 산정방법은 해당 도로의 차로폭과 설계속도를 고려치 않는 일률적인 산정방법이라는 문제점이 있음을 발견하였다. 이런 문제점을 보완하기 위해 본 연구에서는 확폭에 대한 새로운 개념을 도입하였다. 즉, 기존의 차량 기하와 곡선반경의 관계만에 의한 확폭개념이 아니라 곡선 부에서 필요로 하는 폭과 직선부 도로 폭과의 차이를 확폭량으로 하는 개념이다. 곡선부에서의 필요폭은 차량의 주행폭과 측면 여유폭, 그리고 곡선부에서의 주행곤란성을 감안한 추가 여유폭으로 이뤄지며, 직선부에서의 필요폭은 직선부 차로폭에 차로수를 곱한 값이 된다. 새로운 개념의 도입결과, 같은 곡선반경 값을 갖는 곡선부에 대해 전반적으로 현재 한국 도 로시설기준령에서 제시하는 기준값을 상회하는 값이 도출되었다. 본 연구는 저속 offtracking을 기준으로 수행되었으며, 보다 정밀한 확폭량의 산정을 위해 평면곡선부의 편경사와 고속 offtracking현상에 대한 연구가 계속되어야 할 것이다. 제대로 정착될 수 있기 때문이다. 이 모델의 타당성 여부는 후속적 실증연구를 통해 해명되어질 수 있을 것이다.정이 가능하여, 일반적으로 실제 OD를 알 수 없는 (기존OD의 오차가 어느 정도인지를 알 수 없는) 도시부 네트워크에서 신뢰성있는 추정력을 보였다.e service again quality perception level. 2) After classifying customers into 3 groups according to two criteria -"will buy the service again" and "will suggest it to others" and making a pair of service providers with each customer, each customer loyalty group compared the service quality perception factor of the food service provider. The result was that the group having both the " will buy the service again" and "will suggest to others" criteria, that is, with higher loyalty, tend to have higher points than other group s in the dimension of ′Employee attitude′ and ′ Cleanliness′(p〈0.05), which means these two dimensions are closely related to customer loyalty. 3) From a regression
