The purpose of this study is to review an overview of the current tax system for real estate and provide the directions for developing tax system for real estate in Korea. The taxation of acquisition of real estate are Acquisition Tax, Registration Tax, Inheritance Tax and Gift Tax, Value Added Tax, Stamp Tax and License Tax. The taxation of holding real estate are Property Tax, Aggregate Land Tax, Urban Planning Tax, Community Facility Tax, Income Tax, Corporation Tax, Value Added Tax, Farmland Tax, Asset Revaluation Tax, Business Place Tax, and Inhabitant Tax. And the taxation of selling real estate are Income Tax, Corporation Tax, Value Added Tax, Stamp Tax, Inhabitant Tax and Special Tax for Rural Development. The goals of developing tax system for real estate are to enhance economic justice and facilitate the sound development of the national economy. The property tax system will be renewed by reinforcing taxation on real estate holdings. This includes; a progressive aggregate land tax consolidating the property tax on land; a ceiling on ownership of residential land. In addition the scope of tax preferences on capital gains from real estate transfers will be sharply narrowed. In an effort to broaden tax bases, the government also curtailed tax exemptions and reductions.

Objectives: This study was conducted to evaluate individual susceptibility to carpal tunnel syndrome (CTS) by ultrasonographic measurement of the carpal tunnel configuration in workers doing repetitive work. Methods: The study subjects consisted of 24 male and 11 female workers in a soundproof material manufacturing company in Gyeongju. We conducted a self-reported questionnaire survey, a physical examination and an electrodiagnostic study (EDS) in April 2000. After the examination, jobs were rearranged for workers with CTS. A follow up physical examination. EDS, and measurement of the carpal tunnel by ultrasonography was done six monsths later. Results: Of those studied. prevalence or CTS was 63.6/100 persons among women and 29.2/100 persons among men. Mean depth and width of wrist was shorter in those with CTS compareal to the controls (p<0.05). The risk of CTS was higher in workers whose carpal tunnel ratio (displacement/width) was 0.17 or higher (OR 7.13, 95% confidence interval 1.18-43.1), and in workers whose carpal tunnel area was less than 300 ㎟ (OR 8.00, 95% confidence interval 1.18-68.5). Carpal tunnel depth and depth/width ratio had a positive correlation with motor latency of the median nerve and median-ulnar sensory latency difference (p<0.05). whereas the carpal tunnel width. displacement/depth ratio, and area (width×displacement) had a negative correlation with median nerve latencies after adjusting for gender. Workers who showed an improvement in the clinical stage of CTS after job rearrangement had a significantly lower carpal tunnel displacement/width ratio and displacement/depth ratio. They also had smaller upper carpal tunnel area (width×displacement) and larger upper carpal tunner\l area [(depth-displacement)×width] than the controls (p<0.05). Conclusions:Ultrasonographic measurement of the carpal tunnel is a good predictor of susceptibility and prognosis of CTS in workers doing repetivive work.

The purpose of this study was to investigate the perception and eating behaviors of middle school students on Kwangju area about food and nutrition section of Home Economics course. The subjects were 480 middle school students. The major results were as follows; On the perception of food and nutrition section, the 1st graders learned 'how to settle the problems related to food and nutrition and food choices.' The 2nd grades learned 'the knowledge and principle of food and nutrition for improving dietary life.' The 3rd graders learned 'actual dietary life functions like arranging menu and preparing meals.' Consequently, there was a significant difference ineach grade and all boy and girl students have the highest response to the item 'they learn how to settle the nutrition problem and foods choices.' On the interests in the food and nutrition section, lower graders and girl students have higher interest than higher graders and boy students. The area which was considered as most interesting in food and nutrition sections was 'cooking' in all students. The perception of the concern on dietary life after learning food and nutrition section, the 1st graders responded there was a great change in 'balanced dietary life', the 2nd graders in 'eating habit and nutrition of adolescence' and the 3rd graders in 'cooking'. Especially, girl students showed more changes. On the perception of degree which food and nutrition section gives a help to actual life, students over 50% responded that it was helpful to their actual life, This showed that the lower the grades, the more help it grove to those students. On the perception of mother's job, the students with working mother considered that they learned 'actual dietary life functions like arranging menu and preparing meals' from the food and nutrition section. In addition, they had high interests in the area of 'cooking'. It was recognized that as the family size was greater, the food and nutrition section gave more helps to actual life. On eating behaviors of breakfast, the higher the grads, the more frequent they don't have breakfast, boy students have more frequencies of having breakfast than girl students and the primary reason of not having breakfast is poor appetite. On whether going without a meal affects study or not, most of the 1st, 2nd and 3rd graders whether they are boys and girls or not responded it affected their study. On eating behaviors of lunch, most of boy and girl students in the 1st. 2nd and 3rd grade have lunch box. On eating behaviors of supper. eating time is usually between 7:00 and 8:00 p.m and eating hour is mostly 10 or 15 minutes. On eating behaviors between meals, frequencies of eating between meals and mostly once or twice a day and girl students have more frequencies of eating between meals, and the cause was hunger commonly in boy and gill students and 'killing time' in girl students, The focus in getting the foods is 'taste' and favorite food is fruit regardless of the grade.

We reviewed 10 years experiences of the clinical aspects and early postoperative results in 544 pediatric patients(age less than 16 years old). Among them. 529 cases had the congenital heart diseases, and 15 had the acquired diseases. Open heart surgery was performed in 413 patients. 115 cases were treated with non-open heart surgery. 16 with interventional catheterization. Annual increase of the cardiac patients was not significant in recent 10 years, except slight increase in 1994. The mean age of the study patients had been evidently changed to younger year by year. Total mortality rate of the open heart surgery was 6.4%. The cyanotic congenital heart diseases were high in early postoperative mortality by 25.7%, whereas 4% in acyanotic group. The age group less than one month was most highest in surgical mortality(66.7%). There were no deaths in patients with patent ductus arteriosus(103 cases), atrial septal defect(83 cases) or pulmonary stenosis(17 cases). Among 220 patients with ventricular septal defects(VSD). 10(4.5%) were died early postoperatively. In cyanotic group, the patients with pulmonary atresia with ventricular septal defects(PAVSD), transposition of the great arteries(TGA), interrupted aortic arch(IAA), complex cardiac anomalies with isomerism seemed to be most susceptible to an early death.

초고진공에서 공상에피택시(solid-phase epiyaxy, SPE) 방법으로 CoSi₂를 Si(111)기판 위에 에피택시 성장시켰다. 2MeV⁴He++ ion후방산란 분광기와 사중결정 x-선 회절기 및 고분해 투과전자 현미경을 이용하여 성장된 CoSi₂의 상과 조성, 결정성, 그리고 계면의 미시구조를 조사하였다. 초고진공상태의 실온에서 Si(111)-7X7기판에 Co를 약 20 ~50 ?? 중착한 후 SPE에 의하여 실리사이드를 형성시키는 경우 600℃에서는 B-형의 CoSi₂가, 그리고 700℃에서는 A형의 CoSi₂가 선택적으로 에피택시 성장하였으며, 정합성은 B-CoSi₂[110]//Si[110] and CoSi₂(111)//Si(111)이, 그리고 700℃에서는 A-CoSi₂[110]//Si[110], CoSi₂(002)//Si(002)을 나타내었다. Epitaxial films of CoSi₂were grown on Si(111) substrates by in situ solid-phase epitaxy in a ultrahigh vacuum. The phase, the chemical composition, the crystallinity, and the microstructure of the Silicide/Si interface were investigated by 2-MeV⁴He++ ion-backscattering spectrometry, quadruple crystal X-ray diffractometry, and high-resolution transmission eletron micorscopy. High-quality films of either B-type or A-type CoSi₂ could be grown selectively on Si(111) substrates by depositing ~ 20 ~ 50 ?? of Co on a Si(111)-7X7 substrate followed by in situ annealing at 600℃ or 700℃ for 10 min. The matching face relationships are CoSi₂[110]//Si[110] and CoSi₂(111)//Si(111) by B-type CoSi₂ and CoSi₂[110]//Si[110]//Si[110] and CoSi₂(002)//Si(002) for A-type CoSi₂.
