Purpose: We conducted phenomenological qualitative research to provide in depth understanding on infectious disease management. Methods: Participants were 10 nurses working in an isolation ward, where only patients with infectious diseases were institutionalized in one general hospital in Seoul. Data were collected through individual interviews and analyzed according to Colaizzi data analysis method. Results: The main theme of the experience of the nurses who worked in the isolated ward was ‘Nurse's sense of duty to overcome the fear of infection’. Through 83 meaningful re-statements and 13 themes, three sub-themes including ‘Unstable isolation ward’, ‘Taking care of infected patients’ and ‘Insufficient isolation patient care system’. Conclusion: Nurses, working in the new isolation ward, work in a lonely and dangerous environment having fear of infection, being lack of supplies and overcoming various psychological difficulties. In-depth understanding of these needs require efficient infection management policies, measures, and societal recognition.

Purpose: Compassionate act is important factors for staff-nurse to be able for them to work within friendly organizational culture at a hospital setting. The purpose of this study was to investigate the usefulness of the collective compassion process for human resources management in hospital. Collective compassion process was consisted of collectively noticing, collectively feeling, and collectively responding. Collective compassion process can decrease personal suffering at work settings. Compassion process have 3 dimensions-personal, organizational culture, and institutional. Methods: 22 staff nurses and 5 nurse managers were participated in the study. Data were collected with in-depth personal interviews. Collected data were analyzed with content analysis. Results: Staff nurse felt absence of compassion processes of 3 dimensions (personal, organizational culture, and institutional) when they were in suffering. However nurse managers asserted that hospital organization has the compassion processes of 3 dimensions for staff nurses. Absence of compassionate act in the nursing field was one of reasons that they quit their job. Conclusion: The result of this study provided one of the empirical evidences of the importance of compassion process in nursing organizations. Thus we recommend developing an intervention program to increase compassionate act for reducing nurse's suffering.

Low sodium (1,300 mg) containing menu items and recipes applicable to institutional food services were developed while maintaining taste and nutrition contents. These developed recipes were used in a total of 258 dish items, including 39 onedish meals, 43 guk or jjigae (soups or pot stews), 59 meat or fish side-dishes, 94 vegetable side-dishes, 9 jeons (pan-fried dishes), and 14 kimchis or pickles. A total of 90 menu items using 258 dishes were categorized into one-dish menu items or Korean dining table-setting items. They were re-sorted to soup or pot stew containing or not containing items. The protein content was significantly higher in one-dish menus than in Korean dining table-setting menus (p<0.05), whereas the energy, carbohydrates, lipids, and sodium did not differ significantly between them. Menus including guk showed no significant differences in energy, carbohydrates, lipids, or sodium when compared with menus not including guk. For practical application of these developed low sodium menu items for institutional food services, education manuals for nutrition should be developed, and networks among governmental agencies, institutional food services and research institutions should be established.

Purpose: This study investigated the dietary patterns associated with Korean food and the level of proper eating habits according to recognition of the Kimchi cooking method, and aimed to suggest the necessity of dietary education of traditional foods such as Kimchi. Methods: Based on the results of the national dietary survey conducted in 2014 by Ministry of Agriculture, Food and Rural Affairs of Korea, a total of 1200 subjects were classified into two groups, one that knew how to make Kimchi (53.8%) and another that did not (46.2%). Results: The group that knew how to make Kimchi (FG) showed significantly higher scores in knowledge of how to cook most types of Korean foods and traditional fermented foods than the other group (NG). Moreover, FG showed significantly higher scores in regularity in meals and a higher frequency of Korean foods such as rice, Kimchi, and grilled or stewed food, while it showed significantly lower scores in dietary risk factors than NG. In addition, FG showed significantly higher scores in dietary education interest and number of meals with family during the week than NG. Finally, FG had significantly higher scores in the degrees of practice of all eight items related to proper eating habits. Conclusion: Since recognition of Kimchi cooking has a great influence on maintenance of dietary life, dietary education to improve the cooking ability of traditional foods should be further strengthened.

Purpose: The purpose of this study was to understand the lived experience of a main caregiver, in charge of a family member with a severe chronic disease. Methods: The participants of this study were 13 main caregivers, who have a family member with a severe chronic disease. The data were analyzed through the phenomenological research method. Results: This research concluded with: one core theme, five theme clusters and 13 themes. The one core theme was: ‘My Life is Not Mine.’ The five theme clusters include: ‘The Dark Days Ahead, of What We Do,’ ‘Serious Pressure,’ ‘My Body is Broken (caregivers),’ ‘Overcoming,’ and finally ‘Endless, Long and Long tunnel.’ Conclusion: We must emphasize to a main caregiver of a chronic disease patient, to the fact that their life should be theirs, not the patients. In addition, we need to be attentive of their well-being, as well as the chronic disease Patients, and sensitively responsive to their problems.

The purpose of this study was to evaluate the nutrient intake, diversity and prevalence of diseases according to noodle consumption using data from the Korean National Health and Nutrition Examination Survey (KNHANES) of 2010. Korean adults (>20) were classified into two groups, noodle group (NG) and non-noodle group (NNG). NG was found to have higher intakes of protein, calcium, iron, sodium, potassium, and niacin. The DVS and DDS according to noodle consumption were found to be 21.76 and 3.51 for NG, and 18.56 and 3.40 for NNG, this result was thought to show that the diet of NG was more satisfactory than that of NNG in terms of dietary diversity. In the bone mass of entire subjects, NG showed higher figures in the femoral neck and lumbar spine than NNG. For bone mineral density, NG exhibited higher figures in the femoral neck, and for T-scores, the values of NG was significantly higher in the femoral neck than those of NNG. However, the prevalence of osteoporosis of NG and NNG was 11.6% and 9.5%. The prevalence of osteopenia of NG and NNG was 43.0% and 51.7%. Thus, these results showed that overall bone health of NG was better than that of NNG. Dietary balance and quality were also more satisfactory in NG. These results showed that noodle consumption may have an impact on the prevalence of chronic diseases.

PURPOSES : This study compared two measures of traffic flow effectiveness on roads with roundabouts and signalized intersections and determined the more appropriate measure. METHODS: In addition to average delay time, the conventionally used measure, average travel time was introduced to measure traffic flow effectiveness because it is able to be obtained through field survey and reflect different travel distances and speed limits of roundabouts and signalized intersections. Using the two measures, roundabouts and signalized intersections were compared through simulations in terms of traffic flow effectiveness. RESULTS : For one-way single-lane roads, the two measures indicated consistent results that roundabouts were more effective than were signalized intersections when the traffic volume was less than 300 vphpl but vice versa when it exceeded 450 vphpl; however, the measures yielded inconsistent results when the volume was 350~400 vphpl. For one-way double-lane roads, the two measures indicated consistent results that roundabouts were more effective than were signalized intersections when the volume was less than 200 vphpl but vice versa when it exceeded 400 vphpl; however, the measures yielded inconsistent results when the volume was 250~350 vphpl. The results obtained using the two measures differed substantially for double-lane roads because behaviors such as weaving and lane changing at roundabouts are more common in double-lane roads than in single-lane roads. CONCLUSIONS : The average delay time would be lower on roads with roundabouts, but average travel time would be lower on roads with signalized intersections. Thus, evaluating the relative effectiveness of roads with roundabouts and signalized intersections by using average delay time alone would be inappropriate, whereas using average travel time as the evaluation index would yield fairer results.

Purpose: The purpose of this study was understanding of real experiences of the subjects taking anti-psychotics medication. Methods: The subjects of this study were 14 mentally ill patients hospitalized in C National Hospital. The interview data were analyzed with ethnography researchmethod. Results: 26 themes were drawn, and they were categorized into 5 categories. The 1st category was the stage not to acknowledge themselves as mentally ill patients, as mentally ill patients were forced to be hospitalized in the mental hospital by their family, when their mental illness developed. The second category was the stage to endure difficulties while taking medication. The third category was the stage to experience recurrence of disease. The fourth category is the stage to experience improvement of mental illness with medication. The fifth category is the stage to reflect thembecause of the improvement of mental illness, and to express confidence and will about medication after being discharged from the hospital. Conclusion:Nurses actually have to provide total care bymaking thementally ill patients feel comfortable not to have resistance about medication, when they are hospitalized, closely observing medication actions and side effects, and sharing difficulties felt by the patients.

PURPOSES : The purpose of this study is to present a linear programing optimization model for the design of lane-based lane-uses and signal timings for an isolated intersection. METHODS: For the optimization model, a set of constraints for lane-uses and signal settings are identified to ensure feasibility and safety of traffic flow. Three types of objective functions are introduced for optimizing lane-uses and signal operation, including 1) flow ratio minimization of a dual-ring signal control system, 2) cycle length minimization, and 3) capacity maximization. RESULTS : The three types of model were evaluated in terms of minimizing delay time. From the experimental results, the flow ratio minimization model proved to be more effective in reducing delay time than cycle length minimization and capacity maximization models and provided reasonable cycle lengths located between those of other two models. CONCLUSIONS : It was concluded that the flow ratio minimization objective function is the proper one to implement for lane-uses and signal settings optimization to reduce delay time for signalized intersections.

전반적인 경영환경의 글로벌화가 진전되고 기업의 국제 활동이 더욱 증가함에 따라 서비스기업들의 국제 활동 도 증가하고 있다. 다국적 기업의 해외시장 진입방식 선택 문제는 국제화 전략과 관련된 가장 중요한 의사결정 영역 중의 하나이다. 서비스기업에 있어서도 이러한 연구주제에 대한 학자들의 관심이 비교적 많은 편이지만, 서 비스기업 중 외식서비스기업에 대한 연구는 그 해외진출 활동 현황에 비해 아직 부족한 실정이다. 본 연구는 제조업과 구별되는 서비스 특성을 지닌 한국 외식서비스기업을 대상으로 해외시장 진입방식 및 경영 통제수준 결정요인이라는 연구주제를 고찰하고 실증적으로 분석하였다. 84개 기업, 103개 브랜드, 246개 해외 진출 건수를 표본으로 설문조사하여 얻은 107개(응답률 43.5%) 자료에 대한 로짓과 회귀분석 결과 진입방식과 경영 통제수준의 결정요인은 상당히 다르게 나타났다. 한국 외식서비스기업의 해외시장 진입방식 결정에는 서비스의 종류, 경쟁우위, 기업의 규모 등이 통계적으로 유의한 영향을 미치는 것으로 나타났으며, 경영 통제수준에는 경쟁우위, 국제 경험, 문화적 거리, 시장기회, 최고 경영자의 마인드 등이 영향을 미치는 것으로 분석되었다. 이는 진입방식과 경영 통제수준 사이의 관련성에도 불구하고 이 둘에 대한 연구 접근 방식이 달라야 함을 의미하기도 한다.

Background/Aims: The ballooning time in endoscopic papillary large balloon dilation (EPLBD) remains controversial. The aim of this study was to evaluate the significance of the ballooning time comparing an immediate balloon deflation method with a conventional ballooning time of > 45 seconds. Methods: Between January 2010 and December 2010, 126 patients with bile duct stones treated with EPLBD and endoscopic sphincterotomy were divided according to the ballooning time: the immediate deflation group (n=56) and the conventional inflation group (ballooning time 45s to < 60s) (n=70). Results: The overall success rate and the success rate of the first attempt of ERCP (endoscopic retrograde cholangio-pancreatography) were 96.4% (54/56) and 80.4% (45/56) in the immediate group and 97.1% (68/70) and 77.1% (54/70) in the conventional inflation group. There were no statistically significant differences in the overall success and the first attempt of ERCP success rate (p=0.99, p=0.66). The frequency of mechanical lithotripsy was 0% in the immediate deflation group and 7.1% in the conventional inflation group (p=0.065). Complications occurred in 3.6% (2/56) patients in the immediate deflation group and 8.6% (4/70) patients in the conventional inflation group (p=0.298). Conclusions: The ballooning time in EPLBD does not affect the outcomes of the treatment for bile duct stones. And the feasibility of the immediate deflation method in EPLBD is acceptable.

This study was conducted to investigate the degree of practice of dietary behavior and dining out in accordance with intake of sodium among male and female adults aged 20 years or older residing in the Seoul Metropolitan area or Chungcheong Province. A total of 530 copies of the questionnaire were distributed from May to July, 2014. The SH group who responded that they eat a lot of sodium constituted 30.6% (158 people), followed by the SM group who responded that their sodium intake is about average at 55.7% (288 people) and the SL group who answered that they do not eat much sodium at 13.7% (71 people). Those in the SL group showed positive results for dietary behavior patterns. The SL group showed the lowest rate in terms of how often they eat harmful foods, including processed foods, sweet foods, salty foods, or food with high animal fat content such as pork belly. Positive results among the SL group were prominent in terms of avoiding over-drinking, regular exercise, and nutritional knowledge, indicating greater health management. The distribution of each group in terms of self-perceived sodium intake showed significant differences across age, gender, and household income in terms of frequency of fast food intake, regularity of meals, purchase of foods with consideration of sodium amount, frequency of missed meals, balance of food intake, and health management habits.
