This study evaluates the poverty experiences of low-income single mothers according to the Capability Approach of Amartya Sen. In this approach, the capability to achieve the basic functionings of life, not income itself, is the criterion of poverty. 26 single mothers were interviewed using focus-group interviews and in-depth interviews. 21 functionings on the existence level, 18 on the relatedness level, and 15 on the growth level were found in the areas of work, health, food consumption, clothing, housing, child rearing, and leisure. The results of this study suggest that low-income single mothers can achieve only some of the existence level functionings with significant help from welfare services. They can scarcely achieve higher level functionings in any of these areas.

This study is an attempt to evaluate the effect of the medication and symptoms self-care education on the psychiatric patients' quality of life. This exploratory study was designed to a quasi-experiment of pretest-postest with a non equivalent control group. Subjects of 40 patients who were discharged from a mental hospital in Pusan were selected to be experiment and control group, with each group consisting of 20. The research period was from March, 6 to May, 29, 1999 and the pre-post test was given before and after implementing MSSE to the both experiment and control group. The results finding were summarized as follows ; 1. subjects who attended self-care education scored significantly higher than control group in quality of life.(Z=-2.06, P=0.034) 2. Those who were in the experiment group reported more significant higher scores than control group in item of quality of life, living situation(A=-2.62 P=0.012), relations with spouse (Z=-2.31 P=0.038) and children (Z=3.37, P=0.008), fear (Z=-1 95, P=0.049) and anger(Z=-2.07 P=0.041), work functioning (Z=-2.34, P=0.021), environmental adjustment.

This study was mainly aimed to investigate on the perceptions of occupational suitability for speakers who stutter and the associated factors. 90 college students who do not stutter participated in this study and asked to hear one of three audio recordings(i.e., fluent version, mildly-stuttered version, and severely-stuttered version) of a male speaker who stuttered. Then, the participants were asked to rate the speaker's communicative functioning, personal attributes, and suitability for 31 occupations, along with perceptions of the occupations' speaking demands and educational requirements. Results show that speakers who stuttered (i.e., mildly-stuttered and severely-stuttered version) received lower suitability ratings for high speaking demand occupations than for low speaking demand occupations. In addition, it has been shown that perceived speaking demand strongly affected occupational suitability ratings at both levels of stuttering severity. However, it has been shown that occupational suitability ratings were not associated with ratings of the speaker's personal attributes and perceived educational requirements. From these findings it can be argued that adults who stutter may face occupational stereotyping and/or role entrapment in work settings.

Sudden voltage drops and outages frequently disturb the operation of sensitive loads for domestic, commercial, and industrial use. In some cases, these events may even impair the functioning of relevant equipment. To maintain power under such conditions, a UPS system is usually installed. Once a disturbance happens at the grid side, the line-interactive UPS system takes over the load to prevent an interruption. But, due to magnetic saturation of the transformer, a significant inrush current may occur for the transformer-coupled loads during this transition. The generation of such transient currents may in turn decrease the line voltage and activates over-current protecting devices of the system. In this work, a cost-effective, line-interactive UPS system is proposed that eliminates the inrush current phenomenon associated with transformer-coupled loads. The strategy was implemented by connecting a standard current-regulated voltage source inverter (CRVSI) to the secondary winding of the load transformer. During any transient condition at the grid side, the load current is monitored and regulated to achieve either seamless compensation of the load current or complete transferal of load from grid to the inverter. Experimental results were obtained for a prototype under all possible operating conditions so as to validate the performance of the proposed topology.

The Tridosha theory, which is the cornerstone of Ayurvedic physiology governs all the functions of human body and mind. Tridosha are responsible in determining one's Prakriti and their functional status may vary in both gender of different Prakriti. No research work is available to assess the functions of Dosha by objective parameters. Therefore, this study was planned to find out the variation in functional status of different types of Pitta, using certain objective parameters, in 201 young healthy volunteers of both gender belonging to different Prakriti. Serum level of triglycerides, cholesterol, total protein and glucose level were estimated for Pachaka Pitta and hemoglobin concentration for Ranjaka Pitta, visual acuity for Alochaka Pitta, memory and reaction time for Sadhaka Pitta and RGB value for Bhrajaka Pitta were measured. Except the functioning of Bhrajaka Pitta, variation in functional status of all type of Pitta was not the same in different Prakriti of both gender. However these findings were not significant which may have occurred due to small sample size and homogenous population. Thus we propose the consideration of sex differences while planning and evaluating the studies that are based on Prakriti.

This work deals with dynamic analysis of a monorail system with magnetic caterpillar where magnets are embedded inside each articulated element of the caterpillar, augmenting traction force of main rubber wheels to climb up slope up to 15 degree grade. Considerations are first given to determine stiffness of the primary and secondary suspension springs in order for the natural frequencies of car body and bogie associated with vertical, pitch, roll and yaw motion to be within generally accepted range of 1-2 Hz. Equations for calculating magnetic force needed to climb up given slope are derived, and a magnetic caterpillar system for 1/6 scale monorail is designed based on the derivation. To assess the hill climbing ability and cornering stability, and make sure smooth operation of the side and vertical guiding wheels which is critical for safety, a multibody model that takes into account of every component level design characteristics of car, bogie, and caterpillar is set up. Through hill climbing simulation and comparison with measurement of the limit slope, the validity of the analysis and design of the magnetic caterpillar system are demonstrated. Also by studying the curving behavior, maximum curving speed without rollover, functioning of lateral motion constraint system, the effects of geometry of guiding rails are studied.

Protecting an infant from a risk of accident was an absolute responsibility and duty of parents in the past. As increase in the ratio of entering kindergartens, the demand of all day program also increases. In infancy, safety concerns are higher than other periods since infants are curious about objects and environments and that have stronger impulse of the spirit of inquiry. Since baby's functioning is poor, an ability of balance maintenance and an exercise function are not sufficiently developed. Further more, they lack a cognitive power about self-control or situation. According to Korea Consumer Agency, safety accidents in infant institution have increased in 115% as 294 cases compared with 137 cases in 2004. Major causes of infant deaths are street accidents, drowning, and deaths from a fall in order. Considering this situation, we need to prevent and deal with accidents. Therefore this thesis grasp the situation and analyze an actual condition of an safety education about teachers who work in such institutions and infants who are educated in institutions to prevent from accidents and make up pleasant environments. Then, it will suggest all efficient safety education plans for infants to them.

The extract of European mistletoe ( Viscum album, L) has been used in adjuvant chemotherapy of cancer and mistletoe lectins are considered to be major active components. The present work was performed to investigate the effects of Korean mistletoe lectin (Viscum album L. coleratum agglutinin, VCA) on proliferation and apoptosis of human hepatoma cells as well as the underlying mechamisns for these effects. We showed that VCA induced atoptosis in both SK-Hep-1 and Hep 3B (p53-negative) cells through p53- and p21 -independent pathways. VCA induced apoptosis by down-regulation of Bcl-2 and by up-regulation of Bax functioning upstream of caspase-3 in both cell lines. In addition, we observed down-regulation of telomerase activity in both VCA-treated cells. Our results provide direct evidence of the anti-tumor potential of this biological response which comes from inhibition of telomerase and consequent inducing apoptosis. VCA-induced apoptosis is regulated by mitochondria controlled pathway independently of p53. These findings are important for the therapy with preparation of mistletoe because they show that telomerase-dependent mechanism can be targeted by VCA in human hepatocarcinoma. Taken together, our results suggest that the VCA, considered as a telomerase-inhibitor, can be envisaged as a candidate for enhancing sensitivity of conventional anticancer drugs.

Homelessness became a major social problem in Korea. And the homeless presents many kinds of problems in social functioning. In studies on the homeless, Physical and mental health, alcohol and subtance abuse, the vulnerability of the social support have been frequently described as major characteristics of the homeless. Of the homeless' psychosocial characteristics, this article focused on the lack of the social support, which plays a important role on the exit from homelessness. The lack of social support has been mentioned as cause for homelessness. But a few researchers stressed the perspective that the homelessness causes the lack of social support. This article analyzed empirically the lack of social support among the homeless in terms of "social disaffiliation". This article hypothesized: (a) as longer homeless duration, the extent of the perceived social support would be decreased, (b) as longer homeless duration, the magnitude of the social network would be decreased, (c) as longer homeless duration, the ratio of the homeless in social network would be increased. Survey data collected from 355 homeless persons (sheltered homeless) at 82 shelters in Seoul. The result of analysis supports 'social disaffiliation hypotheses'. The result of this study suggests that the social work intervention to strengthen social support and social network be critically important in homeless shelter.
