High level of accuracy in forecasting heat demand of each district is required for operating and managing the district heating efficiently. Heat demand has a close connection with the demands of the previous days and the temperature, general demand forecasting methods may be used forecast. However, there are some exceptional situations to apply general methods such as the exceptional low demand in weekends or vacation period. We introduce a new method to forecast the heat demand to overcome these situations, using the linearities between the demand and some other factors. Our method uses the temperature and the past 7 days' demands as the factors which determine the future demand. The model consists of daily and hourly models which are multiple linear regression models. Appling these two models to historical data, we confirmed that our method can forecast the heat demand correctly with reasonable errors.

Ostomates have suffered from many difficulties due to their physical, psychosocial handicaps and changes of life style to include ostoma management that influences their daily and quality of life. An appropriate nursing education for ostoma management is very important. Practical educational materials needs revision because those were developed by pharmaceutical companies and hospital institutions. The purpose of this study is to provide more practical and reasonable education materials for ostomates by doing analysis and survey of educational materials now being used. We surveyed 8 types of educational materials used in 23 university hospitals and medical centers in Seoul ; four of them were developed by department of nursing and the remainder by an Ostomy Company Data, collected from July 14, 1997 through July 31, 1997 were analyzed. The results are as follows ; 1. The analysis of education guide, on ostomate included 14 subcategories : introduction, structure and function of gastrointestinal tracts, definition of stoma, types of ostomy, definition of peristalsis, methods of defecation management, selection of instrument, resolution of problems and general situations following surgery, daily life, where to ask for help, explanations for terms, information about where to buy instrument, explanations for enterostomal therapist, a matter of consultation with doctor, etc. 2. Introduction contained specific contents on practical ostomate management that ostomates would experience through their lives. Ostomate education guides were developed 3 hospitals except one which missed this point. 3. Most ostomate education guides, except one hospital, helped ostomates to understand their physical structure changes with specific explanations on gastrointestinal tracts with figures. 4. Six institutions did not talk about the definition of peristalsis. 5. All institutions, except two, helped ostomates to understand types of ostomy with figures. 6. More detailed explanations on natural defecation are needed. The benefits and pitfalls of natural defecation should be more specified. 7 No psychosocial difficulties of ostomy management were addressed. 8. The efficiency of enema can be better understood through all explanations with figures. Some institutions did not mention items about definition, benefits, pitfalls of enema, sequency of enema, how to wash, cautions performing and enema, skin management, cleaning instrument after enema proper time to spend. 9. There were no detailed contents and what to do in case of not being able to do enema. 10. Only one educational material mentioned emotional aspects after the surgrey. 11. Most institutions explained subcategory of daily life but did not provide specific contents on the difficulties of physical, psychological, and sociocultural controls. 12. The subcategory of ureterostomy education guides included explanations on normal structure and function of urinary tracts, types of ureterostomy, how to manage skin, usage and types of instrument, commercial urostomy, how to manage instrument, daily life, introduced the general contents.

Purpose: The consistent rise in the number of foreign students in Korea demands an accurate and detailed investigation into their dietary practices and nutritional status. For these international students, assimilation into new cultures can be stressful. The influence this process may have on dietary behaviors as well as overall health cannot be overlooked. Methods: The researchers in this study sought to investigate the nutritional status and dietary practices of Ghanaian students studying in Korea. A total of 81 Ghanaian male students with an average age of $29.4{\pm}4.0years$ were sampled between May and June 2016. Investigations were carried out on the general characteristics of the participants, their daily food and nutrient intakes using a 24-h dietary recall method, meal skipping practices, and the nutritional quality of their diets based on their meal skipping habits. Results: The study revealed that the daily nutrient intake of subjects did not fully meet the daily recommended nutrient intake (RNI) established by Ghanaian Ministry of Health and the World Health Organization (WHO) and Food and Agriculture Organization (FAO), particularly for energy, calcium, iron, zinc, and vitamin B2 requirements. The Nutrient Adequacy Ratio (NAR) for calcium was very low, posing a deficiency risk to the participants. Meal skipping practices among participants changed significantly after arriving in Korea. The study also compared the diet quality indicators (Nutrient Adequacy Ratio and Mean Adequacy Ratio) of those who skipped meals ${\geq}7times/week$ with those who skipped meals < 7 times/week. Participants who skipped meals ${\geq}7times/week$ were shown to have lower dietary intakes of vitamins B1 and B2 than those who skipped meals < 7 times/week. Conclusion: Ultimately, the study found that meal skipping among Ghanaian students was common, and their daily nutrient intakes did not meet the set dietary standards. Those who skipped meals ${\geq}7times/week$ had lower dietary intakes of vitamins B1 and B2 than those who skipped meals < 7 times/week. Based on our study findings, we recommend that nutrition education should be organized for the Ghanaian student community in Korea using our results as a template to draw up a nutrition program that is culturally appropriate.

Objectives: This study was conducted to estimate the cumulative incidence rate (CIR) of unintentional injuries in Korean daily life and to describe the pattern of unintentional injuries. Methods: The study population was the people who used the National Health Insurance because of injuries (ICD code: S00$\sim$T98) during 2006. The stratified sample according to gender, age and the severity of injury (NISS, New Injury Severity Score) was randomly selected. The questions on the questionnaire were developed as a reference for an international classification tool (ICECI, International Classification of External Causes of Injury). The questions included the locations of injury, the mechanisms of injury and the results of injury. Moreover, we used age, gender, region and income variables for analysis. Results: The CIR of unintentional injuries that occurred in daily life for 1 year per 100,000 persons was 17,606, and the CIR of severe injuries was 286. Many injuries were occurred at home (29.6%), public places (19.0%), school (13.7%) and near home (12.0%). The major mechanisms of injuries were slipping (48.8%), contact (14.0%), physical over-exertion (13.8%), and fall (6.6%). Infants and old aged people were vulnerable to injuries, and those who lived rural area and who were in a low income level were vulnerable too. Conclusions: We signified the risk groups and risk settings of unintentional injuries in Korean daily life. These results could contribute to establishing strategies for injury prevention and implementing these strategies.

Background : Validity of WHO guideline of cancer pain management has been proven and many trials have been done to derive solutions for inadequate cancer pain management. We assessed the severity of pain of terminal cancer patients in a few different ways and patients' characteristics influencing inadequate pain management. Methods : This study was based on 100 adult oncological patients who were confirmed as terminal stage in our institution from 3/1998 to 11/1998. Medical records were reviewed and individual patients were interviewed to obtain demographic information and medical characteristics such as: daily activity performance, metastasis, and drug-adjusted pain severity. Adequacy of prescribed analgesics in accordance with WHO guidelines of pain management and patients' characteristics influencing adequacy of pain management were assessed. Results : Among those cancer patients diagnosed as terminal stage, 85% complained of pain, and 68% of those patients reported pain above moderate severity. 38% of those patients received inadequate pain management resulting in greater severity of pain; the less adequate pain relief was(p<0.01). Sex, age, primary cancer site metastasis, symptoms such as depression and anxiety, and daily activity performance were not significantly related. Conclusions : Despite WHO guidelines for pain management, majority of the terminal cancer patients received inadequate pain management. There is a necessity for education on proper pain evaluation and strict implimentation for WHO guidelines of pain management.

The subjects of the study were 673 college students who lived in Seoul and metropolitan areas. Statistical analyses used in the study were factor analysis, Cronbach's a, cluster analysis, ANOVA, Duncan test and $\chi^2-test$. The results of this study were as follows; 1. The body image was categorized into the three factors of personal interest innce, anxiety about weight and physical attraction. Appearance management was categorized into the appearance management through clothing, strict diet therapy and daily appearance management. The psychological well-being was classified as seven factors which include the life goal, self-acceptance, positive personal relations, self-regulation, personal development, environment control and responsibility. 2. The appearance management was classified by 4 groups as below: Daily appearance management group, strict diet therapy group, appearance management through clothing group and no interest in appearance group. 3. There were significant differences among the four groups regarding body image, psychological well-being and life satisfaction. First, appearance management through clothing group had more interest in appearance than other groups. In the case of weight awareness, strict diet therapy group and the appearance management through clothing group intended to have more concerns over their weight.

The purpose of this study was to evaluate the effects of the pain management education on pain of the terminal cancer patients at home. For evaluating the effectiveness of the intervention modified Patient Outcome Questionnaire (APS, 1995) including patients concerns with cancer pain management, pain intensity, and interference of daily activities related to pain were measured before and after the education in control group and experimental group and the differences were compared with each other. Satisfaction with pain management was measured after the intervention. Pain management education was delivered to 16 experimental group patients by home care nurses, who were provided with 3-hour education on cancer pain management by one of the researchers. Pain management education included common misconceptions about cancer pain control and pharmacological and non-pharmacological interventions and emphasis was put on the importance of pain reports and patients' active participation in pain management. The results of the study were as follows. Patients concerns with pain management were decreased more greatly in the experimental group than those of the control group. The worst, average, and present pain intensities during the last 24 hours were decreased more greatly in the experimental group, and total score and each subcategory of the interference of daily living, except walking, were decreased more greatly in the experimental group. And satisfaction score with total pain management and nurses response to the pain reports were higher in the experimental group. The results of this study suggest that pain management education given to the patients by home care nurses is a very useful intervention to improve pain of the cancer patients at home. This positive result is thought to derive from patients' active pain report and participation in pain control and the use of powder form sustained release morphine for breakthrough pain control in part. Further studies with increased sample size from more institutions are recommended and early introduction of short acting morphine is strongly suggested for effective cancer pain control.

Purpose: The purpose of this study was to identify the effects of health status and health management on activities of daily living (ADL) in older, urban-dwelling Koreans. Methods: A total of 206 subjects were recruited from one senior welfare center, six senior citizen centers, and subjects' home in two cities. Data was collected with self-reported questionnaires in order to measure health management, health status, and ADL. Data was analyzed by t-test, ANOVA, and stepwise multiple linear regression using SPSS/WIN 22.0. Results: ADL in this subject were different depending on their age, education, marital status, type of family, and average monthly living expenses. Multivariate analysis showed that age (${\beta}=-0.35$, p<.001), exercise ability (${\beta}=0.20$, p<.001), diabetes (${\beta}=-0.17$, p<.001), osteoarthritis (${\beta}=-0.15$, p<.001), caregiver (${\beta}=0.14$, p=.005), frequency of health management (${\beta}=-0.13$, p=.006), smoking (${\beta}=-0.11$, p=.019), hypertension (${\beta}=-0.10$, p=.027), and type of family (${\beta}=-0.10$, p=.036) were significantly associated with ADL. Overall, approximately 60.2% of total variability in ADL could be explained by the 11 variables in this model ($R^2=0.602$, F=32.06, p<.001). Conclusion: This study suggests that individualized health care should be continued for older, community-dwelling Koreans in order to improve their ADL. Moreover, we need to develop self-care programs and encourage them to participate in those programs.
