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.

This study was conducted to analyze the dental care utilization pattern of the city residents. An interview and questionnaire survey was carried for 1008 people who lived in Kimchun-city, Kyungsangpook-do, from february 1 to March 30, 1992. The summarized results are as follows : The rate of persons who experienced the oral disease was 32.7 per 100 persons during 1 year and it was highest in the age group of 20$\sim$29. During 1 year period, 90.3% of the cases had treated the perceived oral disease, 9.7% had done no action. 65.8% had treated experienced oral disease at dental clinics. The rate of person who dad experienced dental prosthesis during ten-year period was 37.5% among 18year and older, and it was higher in male as compared to female and it was highest in age group of 40$\sim$64 year old. The rate of person who had treated dental prosthetics by the unauthorized illegally was 27.0%, and the reason for it was cheap-price free(44.2%). Of the person who dad treated dental prosthetics by the unauthorized illegally, 64.3% had satisfied and 4.3% had done out of use, while each was 80.1%, 2.7% at dental clinics. The rate of persons with missing teeth was 18.0%. Of the persons with missing teeth, 57.6% did not treat the missing teeth due to economic reason and 89.6% hopped treating the dental prosthetics at dental clinics. In consideration of above finding, we may conclude that oral health community program to prevent oral diseases should be intensified, oral health education to raise oral health knowledge should be performed periodically and the control of unlicensed activities should be enforce at community health center and allows benefits for prosthetics.

The Environmental Impact Quotient(EIQ) has been used to organize the extensive toxicological and soil residue data available on some fruit vegetables pesticides into a usable form for field use. It addresses a majority of the environmental concerns that are encountered in agricultural systems including farm worker, consumer, ecological and environmental safety. The EIQ made use of the rating system by using the EIQ equation. The EIQ of pesticides registered for oriental melon was higher than that of other in terms of farm worker, consumer and environmental safety. Pesticides registered for red pepper showed highest EIQ in ecosystem. The EIQ decreased in order of insecticide> fungicide> herbicide> plant growth regulator. The environment Impact Quotient for the pesticides registered in fruit and vegetables decrease gradually.

Microbial desulfurization characterlstics of a bituminous coal have been determined by using Thiobacillus ferrooxidans. The effects of process variables (such as coal pulp density, particle size and addition of surfactants) on pyrite removal have been investigated in both shake and airlift-bioreactor culture experiments. In shake experiments, pyrite could be removed over 78% for pulp densifies below 20% (w/v) and removed below 40% for pulp densities over 30% (w/v) in 8 days. Pyrite removal decreased with increasing pulp densities, and it also decreased sharply with increasing particle sizes. In airlift bioreactor experiments, pyrite at 50% (w/v) pulp density could be removed about 50%. Its value is much higher than 15% at the same pulp density in a shake experiment. With addition of surfactants, pyrite removal was enhanced in shake experiments significantly, whereas it was slightly decreased in an airlift bioreactor experiment.

The purpose of this study is to develop New-IT internship and to search for the way to reduce quality mismatch and unemployment ratio and to ultimately enhance its effectiveness of university-industry collaboration(UIC) in the field of information technology in Korea. To achieve the goal of this study, we tried to come up with more job creation than working on educational collaboration between university and industry. The survey based on the reaction of companies and interns participating in IT internship program promoted by MKE(Ministry of Knowledge and Economy) shows that intern experience helped them to get jobs and longer intern period gave them to find job more easily. Intern companies preferred to local college students majoring in special technology area related to regional innovation industry cluster. It also found that intern companies wanted to hire interns who had some project experiences and theoretical knowledges. IT Internship program affected students good images about small and medium enterprises(SME) after finishing internship.

This paper proposes a method of generalizing the clocking scheme in the Switched Capacitor Filter(SCF) design using Voltage Inverter Switches (VIS's). Parallel RC and RL elements, and parallel LC resonators can be implemented by the proposed clocking schemes Applying these new elements and the generalized clocking schemes to the SCF design, the total number of required operational amplifiers and capacitors can be reduced. Experimental results of a band- stop filter and a low-pass filter using a new type grounded VIS show good agreements with t he theoretical characteristics.

Cultivation of winter cover crops and its soil utilization for summer main crops in slope upland is very important at the respects of diminution of soil erosion and non-point pollution source. The effects of cover crop, hairy vetch as no-tillage or conventional tillage on prevention of soil erosion and reduction of chemical nitrogen fertilization were investigated in the slope upland with whiter clover living mulch (partial tillage) in Suwon for three years and with rye (conventional tillage) in Hongcheon for two years, respectively. In Suwon, amounts of soil lost by rainfall runoff decreased as much as 90% by hairy vetch-no tillage (HV-NT), white clover-partial tillage (WF-PT) together with the decrease of rainfall runoff compared to winter fallow with conventional tillage (WF-CT). In addition, amounts of weed also decreased as much as 80-90% by HV-NT and WF-PT. Corn yield decreased much at the plot of WF-PT mainly due to competition for soil water and nutrients between clover and corn at the early corn growth stage. On the contrary, corn yield increased by HV-NT compared to WF-CT regardless of weed control. In Hongcheon, amounts of soil eroded during winter season before corn seeding were reduced as much as 95% by cultivation of hairy vetch and rye compared to winter fallow. Amount of soil eroded during waxy corn growing season was reduced as much as 98% by HV-NT compared to WF-CT. Also, soil incorporation of hairy vetch and rye as green manure with conventional tillage at corn seeding time could reduce soil erosion as much as 70% compared to no soil cover with conventional tillage. Ear yields of waxy corn were increased 10% higher at hairy vetch green manure (HV-CT) without nitrogen fertilizer, 20% higher at HV-NT with standard nitrogen fertilizer, respectively than WF-CT. But ear yields of waxy corn were decreased by rye green manure (R-CT) and HV-NT at the condition of no nitrogen fertilizer. It was concluded that hairy vetch was better as winter cover crop to reduce both soil erosion and chemical nitrogen fertilizer simultaneously in slope upland than other cover crops.

The purpose of this study is to develop New-IT internship and to search for the way to reduce quality mismatch and unemployment ratio and to ultimately enhance its effectiveness of university-industry collaboration(UIC) in the field of information technology in Korea. To achieve the goal of this study, we tried to come up with more job creation than educational UIC. The survey(based on CIPP model) based on the reaction of companies and interns participating in IT internship program promoted by MKE(Ministry of Knowledge and Economy) shows that intern experience helped them to get jobs and longer intern period gave them to find job more easily. This program is designed to focus on intern matching between students' major and their intern jobs, and requires new employees' level of job quality. They(56%) preferred to hire local college students majoring in special technology area related to regional innovation industry cluster. It also found that intern companies(87%) wanted to participate in this program again and hired intern students(61%) as showing the possible connection of internship and employment. IT Internship program affected students(68.3%) good images about small and medium enterprises(SME) after finishing internship.
