The sodium-sulfur batteries which operate at $350^{\circ}C$ have been mainly used in the field of energy storage system. This batteries consist of liquid sodium anode, sulfur cathode and ${\beta}^{{\prime}{\prime}}$-alumina solid electrolyte. The conditioning process for stabilization of the batteries is essential since the cells show considerable fluctuation of discharge voltage at the beginning of discharge/charge cycles. It is found that one of the reasons of the fluctuation is the gradual change of contact area between molten sodium and solid electrolyte.

The purpose of the study was to identify the effects of inpatient cardiac rehabilitation programs on motivation, the performance of health behavior, and quality of life in patients with coronary artery disease. The subjects consisted of 31 patients who participated in the rehabilitation program during their hospital stay, and were compared with 34 patients who did not participate. The study results are as follows: 1. The mean of cardiac risk factor scores for the subjects was 22.5 (SD = 5.5) at the level of low to moderate risk with some possibility to improve. The physiological and behavioral risk factors for the subjects were also in the normal range or slightly above the normal range. 2. The motivation level to preform health behaviors for both groups was improved after discharge. Also, perceived self-efficacy was significantly higher for the program participants than for the comparison group at the post-test. 3. The performance of cardiac related health behaviors improved for both groups after discharge, but there were no significant differences between the two groups. The program participants reported better performance in most health behaviors at the post-test, but the results failed to reach a statistical significant level. 4. As for motivation and health behavior, the subjects in the both groups showed an improved quality of life after the discharge. In addition, the program participants produced significantly higher scores in health and functioning dimension than the comparison group during the post-test. In conclusion, the study partially supported the effects of the inpatient cardiac rehabilitation program to motivate and improve the quality of life, and provide the need to apply early rehabilitation interventions for the patients after cardiac events. Further study with a longitudinal design is also suggested to verify the effect of cardiac rehabilitation program from hospitalization to discharge and subsequently to fully recover to the level of pre-hospitalized state.

An external electrode fluorescent lamps (EEFLs) have the advantage of a long lifetime in the early stages of the study on plasma discharge, interest in the lamp continues. Studies on the operation of external electrode fluorescent lamps have focused mainly on its use of a type of high frequency (MHz). By performing high brightness using a square wave operation method with the low frequency below 100kHz, which is applied to a narrowed tube type lamp that has several mm of lamp diameter. To solve these problems of CCFL, EEFL (External Electrode Fluorescent Lamp) is introduced. Because electrode of EEFL is on the outer surface of discharge tube, the electrode is perfectly prevented from the sputtering by accelerated ions. And it is possible to drive the many CCFLs at the same time, because EEFL shows the positively resistant characteristic. But EEFL has the large non-radiative power loss in sheath. In this study the novel electrode structure was introduced in order to reduce non-radiative power loss in sheath of EEFL. The novel electrode structure comes from the idea to combine conceptually capacitive discharge with inductive discharge. Thus, this study verifies the change in the optical characteristics according to the change in electrode structure through a Maxwell's electromagnetic field simulation and examines the relationship between the change in the EEFL electrode structure and brightness by measuring the optical characteristics.

The purpose of this study is to understand the life experience of youth who discharged from out-of-home-care and lived as the unemployed NEET(Not in Education, Employment or Training) youth not established in life. For this study, we collected in-depth interviews with five youth in career moratorium or early discharge from out-of-home care. The results of the study were as follows: we divided into six themes such as "I cannot lean on family of origin", "unstable life", "strayed by wandering and prejudice", "I need someone to rely on", "belated regrets", and "constantly dreaming of resurgence"; and the six themes were analyzed separately in the sub-categories. As a result, we found out that the youth in career moratorium lived a life of regret and recovery in the unstable life journey. Based upon the results, we suggested social welfare practice and policy implications in order to systematically support the NEET youth after discharge from out-of-home-care.

The purpose of this study is to investigate the nutritional status and dietary intake of gastrectomized cancer patients. For this study, from 1993. 1 to 1993. 8, 50 postoperative gastric cancer patients were selected to examine anthropometric and laboratory data(Body Weight, Body Fat, serum Albumin, Total Lympocyte count), and dietary intake related symptoms. The results were 1) All anthropometric and laboratory data were significantly deteriorated by gastrectomy(s-Albumin, TLC. Body Fat : p<0.001). Weight loss of gastrectomized patients was 8.23$\pm$3.72% from admission to discharge. 2) In many gastrectomized cancer patients, preoperative dietary intake was decreased by abdominal discomfort, indigestion, early satiety, and anorexia. 3) Postoperative energy intake was 602$\pm$158㎉, and it is correspond to 31.18$\pm$.90% of daily energy requirement(1918$\pm$236㎉). The cause of poor oral intake is mostly fear, abdominal distension and fullness, and early satiety. In consideration of the fact that an inadequate energy intake was the main cause of the decreasing nutritional status, a careful nutritional care and dietary education is necessry after gastrectomy.

Insulation aging diagnosis system provides early warning in regard to electrical equipment defects. Early warning is very important in that it can avoid great losses resulting from unexpected shutdown of the production line. For solving this problem, many researchers proposed a method that diagnose power plant by using partial discharge. In this paper, we design the intelligent sensor to diagnose insulation degradation state that uses a Microprocessor and Al. Proposed sensor has MCU that is used to diagnose insulation degradation and communicate with main IDD system. And we use a fuzzy model to diagnose insulation degradation.

To study on the behavior of the early stage of the spark kernel at constant pressure condition, the expressions of the thermal properties such as compressibility factor, thermal conductivity, and electrical conductivity of the high temperature air were newly suggested. The newly suggested simple expressions of the thermal properties of the high temperature air showed good results. Under the assumption of constant pressure, one dimensional numerical analysis was executed by varying surrounding conditions and discharging current of electrical spark. Numerical results show tat high surrounding pressure suppresses the growth of the spark kernel but supplies much electrical energy into the air, on the other hand high surrounding temperature increases the growth of the spark kernel but supplies less electrical energy. Also the result shows that , in case of direct current discharge, deposited electrical energy is able to be expressed in linear function of time approximately.

The purpose of this study was to compare the breast feeding practice rates and mothers' breast feeding empowerment in preterm (gestation age [GA]<34), late preterm ($34{\leq}$GA<37), early term infants ($37{\leq}$GA<39). We surveyed 33 preterm, 22 late preterm, and 30 early term infants at a 'Baby-Friendly Hospital' in D city. The data were collected from October 1st, 2008 to February 28th, 2010 through the medical records of the infants and their mothers. We also checked the mothers' breast feeding empowerment at discharge day. The rate of breast feeding in the late preterm and preterm infants was significantly lower than that of the early term infants. The score of mothers' breast feeding empowerment in the late preterm and preterm infants was also significantly lower than that of the early term infants. The breast feeding education program is required for the mothers who have preterm and late preterm infants considering the low rate of breast feeding.

Upper gastrointestinal (GI) bleeding (UGIB) is the most common GI emergency, and it is associated with significant morbidity and mortality. Early identification of low-risk patients suitable for outpatient management has the potential to reduce unnecessary costs, and prompt triage of high-risk patients could allow appropriate intervention and minimize morbidity and mortality. Several risk-scoring systems have been developed to predict the outcomes of UGIB. As each scoring system measures different primary outcome variables, appropriate risk scores must be implemented in clinical practice. The Glasgow-Blatchford score (GBS) should be used to predict the need for interventions such as blood transfusion or endoscopic or surgical treatment. Patients with GBS ${\leq}1$ have a low likelihood of adverse outcomes and can be considered for early discharge. The Rockall score was externally validated and is widely used for prediction of mortality. The recently developed AIMS65 score is easy to calculate and was proposed to predict in-hospital mortality. The Forrest classification is based on endoscopic findings and can be used to stratify patients into high- and low-risk categories in terms of rebleeding and thus is useful in predicting the need for endoscopic hemostasis. Early risk stratification is critical in the management of UGIB and may improve patient outcome and reduce unnecessary health care costs through standardization of care.
