The purposes of this study are to identify effectiveness of the hospital-based home care project, to manage patients' problems in comprehensive way, to decrease the patients' economical burden to the arthritis patients. The design is nonequivalent control group pretest-posttest design with matched samples in terms of age, sex and disease severity. Fifty two patients were assigned in each of the experimental and control groups in Seoul, Kyunggi, Kangwon and Kwangju. Before the experiment and after 3-month period of experiment of home care, level of pain, duration of morning stiffness, Richie Index, ADL, self-efficacy and depression were measured. Nine patients were excluded from the control group because of denial of participation. Contents of home care provided to the experimental group include distribution of prescribed drugs, assessment of patient's condition and side-reactions of drug, pain control, depression control, nutrition guide, exercise teaching, and family counselling. Patients assigned to the control group visited the outpatient clinic once a month as usual. Null hypotheses were selected because physicians concerned about the ineffective change of patients' conditions due to indirect communication with patients through nurses. Level of pain, Richie Index, ADL, self-efficacy, depression and duration of morning stiffness did not significantly different between two groups as expected. In the experimental group, level of pain, ADL, Richie Index and duration of morning stiffness changed to the positive direction from the pretest to the posttest. However, level of depression and self-efficacy did not show any changes. Ninety percent of patients in the experimental group satisfied with the home care provided to them. Since this is the intermediate report, more detailed and long-term report will be prepared.

This paper will discuss about how we can foster educational support mechanisms to facilitate health promotion programs at the local level. Health promotion in Korea is in the early developmental stage; it has only been since the Health Promotion Act was legislated in 1995, the health promotion programs have been planned and implemented. In the context of the recent decentralization process, local health departments have a major responsibility for developing and implementing health promotion programs at the local level. The short history of health promotion in Korea has meant that local public health departments have limited experience and organizational capacity for health promotion planning ＆ practice. The results of one survey for investigating the progress of health promotion at the local level are instructive. The survey demonstrated that the public health workers recognized that the lack of personnels, insufficient budget, the lack of policy ＆ the organizational support, the lack of skill ＆ knowledge to be effective health promotors, the lack of guidance for health promotion practice were major barriers to implementing health promotion programs at the local level. The object of this paper is to suggest some ways of overcoming barriers to implementing health promotion programs at the local level This paper emphasizes on the importance of educational supports as well as environmental supports - legislative, policy, organizational, economical - in building the organizational capacity and infrastructure of local health department for health promotion. It suggests some ways of providing educational supports to the public health workers at the local level. and supports the positions that educational opportunities for training in health promotion can be better provided to the public health workers at the provincial level rather than at the national level. It argues that the educational ＆ training programs should be developed and based on the educational need assessment; that the application of the main educational principles ＆ theoretical models for health promotion be used to develop educational programs for the public health workers; and that professional health organizations should make plans to provide more educational programs at their annual conferences or at other convenient times. These kinds of educational supports facilitate the ability of public health workers to improve their capacity for health promotion practice at the local level and help to alleviate some of the pressure on state resources.

Due to the occasional occurrence of a localizedcorrosion such as a SCC and pitting in steam generator tubing(Alloy 600), leading to a significant economical loss, an effective repair technology is needed. For a successful electrodeposition inside a tube, many processes should be developed. Among these processes, an anode to be installed inside a tube, a degreasing condition to remove any dirt and grease, an activation condition for a surface oxide elimination, a strike layer forming condition which needs to be adhered tightly between an electroforming layer and a parent tube and a condition for an electroforming layer should be established. Through a combination of these various process condition parameters, the desired material properties can be acquired. Among these process parameters, various material properties including a mechanical property and its variation along with the height of the electrodeposit inside a tube as well as its thermal stability and SCC resistance should be assessed for an application in a plant. This work deals with the material properties of the Ni electrodeposits formed inside a tube by using the anode developed in this study such as the current efficiency, hardness, tensile property, thermal stability and SCC behavior of the electrodeposit in a 40wt% NaOH solution at $315^{\circ}C$. It was found that a variation of the material properties within the entire length of the electrodeposit was quite acceptable and the Ni electrodeposit showed an excellent SCC resistance.

Effort has been performed for latest 20 years to improve resident's comfort and indoor environment in building. And interest and effort to improve indoor air environment among various indoor environment elements have continuously increased since 1990s, because it is examined scientifically that various contaminants generated indoor affect human body. Specially, indoor air contaminants generated from apartments are those exhausted from resident's indoor environment, closing materials and household. Indoor air environment in buildings is different according to pollution degree, existence availability of pollution source, ventilation amount, and meteorology. It is known that other contaminants more than about 900 kinds generate according to a kind of work or action in a room. Specially, nowadays buildings are well insulated and confidentiality-centered for environment protection and economical side. So indoor air contaminants are generated from indoor air pollution sauces of unprepared ventilation, human body carbon dioxide emissions, and various building materials. when these are accumulated in long term human body, it is harmful to resident's health, but awareness for this is very insufficient. Because bedroom is space that people inhabit for a long time by unconscious state and indoor environment occupies important part for resident's health and quality of life at sleep, the actual condition of air quality is investigated, improvement countermeasure is considered, and ventilation amount is analyzed. In this study, putting case that the most longest stayed time is sleeping time when people inhabit in the apartment, the air quality according to volume of bedroom space at sleep was measured and analyzed, and the data acquired will be the basis for improvement on this.

Purposes of this study were to identify a hospital-based home care model and to improve the physical, emotional and economical effectiveness of arthritic patients through medical and nursing team approach. The design in nonequivalent control group pretest-posttest design with matched samples in terms of age, sex and disease severity. Fifty two patients in each group were assigned in Seoul, Kyunggi, Kangwon and Kwangju. Before and after 6-month period of home care, level of pain, duration of morning stiffness, Richie Index, ADL, self efficacy, depression, cost expenditure were measured. Nine patients were excluded from the control group in the period of study because of denial of participation. Contents of home care provided to the experimental group include mainly distribution of prescribed drugs, 'assessment of patients' condition and side-reactions of drug. All of the information related to the home care patient were reported to the physician. On the bases of these data, the physician prescribe the specific drugs to each patient. Each patient visited the physician every 2 or 3 month for laboratory test. Patients assigned to the control group visited the outpatient clinic once a month as usual. Null hypotheses were selected because physicians concerned about the ineffective change of patients' conditions due to indirect communication with patients through nurses. Level of pain, Richie index, ADL, self-efficacy, depression, duration of morning stiffness and direct medical cost were the home care provided to them. If a family member accompany in a home care group can save 10,676 Won/month in Seoul, 34,000 Won/month in other districts. Other in-direct cost for transportation and meal can also be saved. In conclusion, those patients with low level of ADL, high level of pain and Richie index, living in the remote area definitely need the home care.

본 연구에서는 해상교량의 선박충돌 해석을 위한 설계선박을 결정하기 위한 선박충돌 위험도 분석을 수행하였다. 확률기반 해석과정을 포함하는 Method II를 이용하여 선박충돌 위험도 해석결과로부터 선박충돌에 대한 설계선박을 선정하였다. 계산연간파괴빈도와 허용기준을 반복 비교하는 해석과정에서는 연간파괴빈도 허용기준의 분배방법이 포함된다. 주탑집중 분배방법이 주탑에 비해 과대평가되는 교각의 설계 수평내하력을 적절히 수정할 경우에는 보다 경제적인 결과를 가져오지만, 교량부재의 중요도를 고려한 가중치에 의한 분배방법이 설계인자의 특성들을 정량적으로 고려하기 때문에 보다 합리적인 것으로 보인다. 선박충돌에 노출된 교각 각각에 대한 선박충돌위험도 평가로부터 교량의 대표 설계선박이 선정되었다. 설계선박은 같은 교량에서도 선박통행량 특성에 따라 많은 차이가 있다.

One hundred ninety-five countries reached agreement on a new climate treaty in Paris, France to reduce the carbon emissions. South Korea has been selected as a target country for reducing greenhouse gas (GHG) obligations since 2020. In this context, the Korean government developed several GHG emissions reduction programs using forests called the "Forest carbon offset scheme (FCOS)." The forest management method is one of the tools to implement FCOS. Most of the participants registered forest management as the preferred methodology to participate in the FCOS. For a successful implementation of the FCOS, it is necessary to explore the optimal methods by considering the cost-effective aspect of conducting the forest management as a tool to increase carbon absorption. In this context, this study investigated the value optimized FCOS projects based on the forest management methodology in South Korea. Three forest management scenarios, 1) extending the final age of maturity of Pinus densiflora stands (S1), 2) extending the final age of maturity of Quercus acutissima stands (S2), and 3) reforestation with new species (Pinus densiflora to Quercus acutissima) (S3), were examined and evaluated to identify the optimal carbon absorption and value optimized economic perspective. The results of the scenario-based modelling indicated that S3 showed value optimized from an economical perspective, and S2 was the most effective method to absorb carbon among the scenarios. It is anticipated that this paper will contribute to provide valuable information by presenting innovative approaches as a value optimized FCOS implementing tool in a GHG reduction program in South Korea.
