This paper presents the policy directions of total maximum daily loads(TMDL), which was recently adopted in Korea, for scientific management of water quality. The basic principles of water quality management are also discussed in this paper, along with the TMDL policy in United States as well as the previous policy in Korea. We discussed several unreasonable points out of the previous approaches, such as regulation of all point sources with equal standards, negligence of an assimilative capacity of the receiving water, and emphasis only on drinking water supply, etc.. For successful applications of the TMDL policy in Korea, the following directions are suggested: 1) the unit drainage basin for each TMDL application should be given, 2) the water body where the water quality standards should be maintained, needs to be guided, 3) the water quality parameters of TMDL should be given, 4) the technical guidances should be given for applications of water quality models, and 5) the seasonal TMDL would be allowed. In order to maximize the benefits of the TMDL policy, the local governments would need to implement the following strategies: 1) the increment of an assimilative capacity of the receiving water, 2) the effective controls of the non-point source pollution, 3) the advanced treatment of the point sources, 4) application of system optimization techniques along with effluent trade, and 5) utilization of watershed management systems.

This paper reviews the literature on life course as a perspective in family studies. Life course approach on family studies have been emerged since 1960. This approach, which is challenging accepted knowledge and theory, partly reflects a shift in analytic perspective from structural models to a more behavioral thrust that views as a actor in structured situations, Life course approach is a theoretical orientation for our understanding of the linkage between individual and family development in context of changing historical context. Life course approach contributes time, process, and context to receiving in sociological perspectives on family and kinship.

In construction work, safety accidents often occur in combination with unstable physical and human conditions during preparation and execution of work. In Korea, the accident rate is higher to that of any country in the world. Therefore, it is necessary to take measures by fundamental prescription. In this paper, in the case of construction safety management, we tried to find a reasonable alternative through a questionnaire survey to apply to subcontracting and small-scale construction. In conclusion, workers who are well aware of the task could be able to reduce the accident rate by deploying them as safety management officers after receiving the training.

Purpose: The purpose of this study was to evaluate food carving among hemodialysis patients and to identify factors affecting the food carving. Methods: A descriptive correlational study was conducted. Data were collected from 129 patients receiving hemodialysis between March 15 and April 15, 2017. Measurement instruments included the general food craving questionnaire trait, the center for epidemiological studies-depression scale, and stress response inventory-modified form. The statistical analysis included t-test, analysis of variance, pearson correlation analysis, and stepwise multiple regression analysis. Results: Mean food craving score was $53.00{\pm}12.36$. Food craving was higher in patients younger than 40 years (F=4.36 p=.006) and having occupation (t=2.18 p=.031). Patients receiving hemodialysis demonstrated higher levels of depression ($21.37{\pm}9.62$) and stress ($39.68{\pm}15.95$). Factors influencing food craving were depression (${\beta}=.52$, p<.001), stress (${\beta}=.65$, p<.001), and age 50~59 years old (${\beta}=-.28$, p=.001) and 60~69 years old (${\beta}=-.19$, p=.026), which accounted for 25.6% of total variance. Conclusion: Food craving among hemodialysis patients was influenced by patients' depression, stress and age. Assessment and management of depression and stress needs to be incorporated as a nursing strategy for dietary management for hemodialysis patients.

By means of the qualitative data analysis their statements were analyzed. 6 groups were classified on the basis of clothing-wearing motives. Generally consumers began to cognize the necessity of clothing and develops it to situational appropriateness psychological comfort impression management distinction desire and finally attention -receiving desire. The levels of clothing-wearing motives were also interpreted as introversion-extroversion theory. These 6 groups were named in consideration of the highest level of their clothing -searing motives They were respectively the least clothing-cognizing group situation-appropriateness cognizing group psychological comfort cognizing group impression management group distinction desire group attention-receiving desire group. The characteristics of each group were represented based on the interview results and the consuming-behavior of each group was compared. finally the interaction of the clothing-wearing motives and the fashion phenomenon was discussed.

Purpose: The objectives of this study were to investigate the current status of the pain in and the dysfunction related to the musculoskeletal system experienced by patients with end-stage renal failure receiving hemodialysis. Methods: A questionnaire survey was given to 107 patients undergoing hemodialysis in M Hospital. The survey was conducted by using a brief pain inventory(BPI) to investigate the body parts in pain, degree of pain, difficulty in daily life, correlation with hemodialysis and the degree of satisfaction with their own health. Results: The investigation of the patients undergoing hemodialysis showed that 89(83.2%) of the 107 patients experienced pain in their musculoskeletal system. Their pain's incidence was highest in the knees(46.1%) and 68.5% of the patients reported that the most severe pain they had experienced within the past 24 hours was at a level between "moderate" and "severe." The limitation of daily life by pain is high most as 47.7% in the accomplishment of works. Conclusion: Most hemodialysis patients experience musculoskeletal related pain that affects their daily life. Hemodialysis patient management programs should include an assessment and management of such pain.

This study proposes a collaboration system framework on the web service in a supply chain to implement an efficient virtual supply chain and improve an ability to fulfill received orders over a supply chain. The system based on the framework proposed in this paper plays an important role for automatic order negotiation and placing/receiving an order noticed in web service by the main system. Furthermore, it can evaluate the fulfillment of received orders over a supply chain by using the transaction results from hierarchically related vendors and establish efficient manufacturing plans. In a word, this system is the automated system for creating manufacturing plans, placing and receiving orders. A little more important main function of this system is that it has a dynamic evaluation capability about fulfillment with received orders over a supply chain, and improves the evaluation method of fulfillment ability with received orders with related to direct dealing vendors, which is a main problem in existing system. As a result, this system is able to reduce the work load of the sales and purchasing materials, production control division, to manage accurate inventory promptly, to maintain the optimal inventory level by analyzing the information of fulfillment ability with received orders, and to enhance the level of service for customers.

SNMP에서는 관리정책에 따라 Manager가 특정 Object 에 대하여 MIB 값을 Agent에 요청하고 Agent가 이에 응답하는 식으로 정보를 송수신하므로 많은 네트워크 traffic이 발생한다. 특히, Traffic의 경향분석 기능 수행시 동일 Object에 대한 반복적인 정보 송수신 발생은 매우 비효율적이다. 본 논문에서는 기존의 SNMP에 시간 기능을 수용할 수 있는 새로운 PDU를 추가하고, 이를 이용하는 Manager와 Agent간에 불필요한 정보 송수신을 최소화하면서 경향 관리 정보를 수집할 수 있는 효율적인 방안을 제시하였다. 시험 결과 구현된 SNMP는 기존 SNMP와 호환성을 유지하면서 네트워크 Traffic을 크게 감소시켰다.
