The purpose this study was to investigate the distribution of VO_2max and changes of blood components during Taekwondo competition. Subjects as a Experimental group were seven well-trained Taekwondo players. Control group was composed of seven healthy male students who are taking participated in Taekwondo club in D university. With K4b^2 telemetry, VO_2max was determined for each subject by administering a treadmill exercise test(5% slope, start speed: 120m/min, increased 20m/min each 2min) Data were analyzed by ANOVA with post test The 0.05 level of significance was as critical level for the study In the Taekwondo competition, glucose and FFA in both group, were increased as each round was repeated, while TG of the Taekwondo player group was increased to the 2nd round, and then decreased in the 3rd round. But in the control group TG tended to increase gradually.

The purpose of this research is to develop the robot vision technology based on pattern recognition for non-contacting inspection optical lens slant or precision parts, and including external form state of lens or electronic parts for the performance verification, this development can achieve badness finding. And, establish to existing reflex data because inputting surface badness degree of scratch's standard specification condition directly, and error designed to distinguish from product more than schedule error to badness product by normalcy product within schedule extent after calculate the error comparing actuality measurement reflex data and standard reflex data mutually. Developed system to smallest 1 pixel unit though measuring is possible 1 pixel as 37㎛×37㎛ (0.1369×0-4mm²) the accuracy to 1.5×10^(-4)mm minutely measuring is possible performance verification and trust ability through an experiment prove.

Various transition metal carbonyl complexes catalyzed the carbonylation of p-xylylene dibromide to give p-phenylenediacetic acid in moderate yields in the presence of phase transfer agents such as crown ether and quaternary ammonium salt at atmospheric pressure of carbon monoxide. These metal complexes were less effective in the case of carbonylation of ortho- and meta-xylylene dibromides. On the other hand, p-tolylacetic acid was predominantly obtained when p-xylylene dichloride was applied to this two phase system. And also, meta-and para-xylylene dibromides reacted with carbon monoxide in the presence of palladium (0) complexes such as tetrakis(triphenylphosphine) palladium (0), and bis (1,2-diphenylphosphinoethane) palladium(0) under phase transfer catalyst to give selectively mono-carbonylated products in reasonable yields.

CdS thin films have been widely used a window material in heterojunction solar cells. In solar cell systems, where CdS thin films have been proved to be useful, partial substitution of Zn for Cd increases the optical window of the hetero-junction and also the diffusion potential. In this thesis, effects of the thickness of indium films and the annealing temperature on structural, optical and electrical properties of chemically deposited CdZnS films for the efficiency of the Cd_(1-x)Zn_(x)S/CdTe solar cells were investigated. Cd_(1-x)Zn_(x)S films were grown by chemical bath deposition (CBD), which is a very attractive method for low-cost and large-area solar cells. The open circuit voltage of Cd_(1-x)Zn_(x)S/CdTe solar cells increased due to reduced electron affinity difference between Cd_(1-x)Zn_(x)S and CdTe films. However, the conversion efficiency of Cd_(1-x)Zn_(x)S/CdTe solar cell decreased because of the higher series resistance(R_(s)) than CdS/CdTe solar cell. The series resistance and conversion efficiency of Cd_(1-x)Zn_(x)S/CdTe solar cell were improved by using indium-doped Cd_(1-x)Zn_(x)S films as window layer. Cd_(1-x)Zn_(x)S/CdTe solar cells fabricated with optimal conditions exhibited V_(oc)=630mV, J_(sc)=38.89mA/㎠ , FF=0.53, and η=13.2%

The purpose of this study is intended for effective recycling of waste concrete. It analyzes the quality 0 the recycled coarse aggregate with production types. The conclusions of the study are as follows. 1. The recycled coarse aggregate which is produced through 5th Crushing Process (A-Type) shows the improvement in grading and particle shape, reduction in an absorption rate until 1.14% due to removal of attached the mortar and paste. Therefore, it satisfies the standards of KS F 2573(recycled aggregate for concrete) as the first grade. 2. The recycled coarse aggregate which is produced through 3rd Crushing Process(B-Type) is suited to the quality prOVlSlOns of the standards of KS F 2573, shows a 3.12% absorption rate that is second grade as recycled coarse aggregate. Based on the above results, it is possible to product first and second grade recycled coarse aggregates with production types. It is concluded that recycled coarse aggregate with production types can be used as aggregate within required conditions. And more researches are also needed to make recycled coarse aggregate better to use for concrete.

Objectives:This study was to identify weight & metabolic changes in first-episode psychotic patients with antipsychotics use and investigate the differences of weight & metabolic changes between first-episode psychotic patients and controls with antipsychotics use. Method:In this retrospective study, twenty eight first-episode psychotic patients and twenty eight controls with schizophrenia, schizoaffective or bipolar disorder defined by DSM-IV criteria were included. Information about demographic and clinical characteristics of the subjects was gathered from the medical records. Also body weight, sBP, dBP, fasting glucose, lipid profile and WBC count were evaluated before and after antipsychotics use. Rogistic regression was conducted to assess factors associated with weight gain. Results:First-episode psychotic patients showed more weight and BMI changes than controls after antipsychotics use, and these changes continue over 12 months. On the other hand, there were no significant factors associated with weight gain. Conclusion:The results of present study suggest that antispychotics is one of the major causes inducing weight gain of psychotic patients and antipsychotics-induced weight gain is more vulnerable to drug-naive first-episode psychotic patients.

Keratosis pilaris (KP) is a common inherited disorder of follicular hyperkeratosis, which is characterized by small, folliculocentric, keratotic papules with surrounding erythema. A 13-year-old boy presented with asymptomatic rough and linear follicular papules on the right flank. The lesion occurred on pre-existent hypopigmented patches several months ago. His past medical history was unremarkable. His father also had KP on the bilateral extensor surfaces of the upper extremities, buttocks, and upper thighs. Skin biopsies were done from follicular papule and hypopigmented patch on the right flank. Histopathologic finding from follicular papule was consistent with keratosis pilaris and revealed decreased melanin from hypopigmented patch. There was only one case of unilateral linear KP on hypopigmented patch in pubmed searching, in which FGFR2 gene mutation may participate in the pathogenesis. We tried to detect FGFR2 gene mutation in our patient but could not find FGFR2 gene mutation from tissues of both lesional and normal skin. We report an extremely rare case of unilateral linear KP occurring on hypopigmented patches and discuss pathogenesis of this peculiar clinical presentation.

Rhabdomyomatous mesenchymal hamartoma (RMH) is a rare congenital skin disease. The lesion commonly presents as a solitary sessile papule or nodule on the head and neck in childhood. Its pathologic finding is characterized by aberrant existence of striated muscle fibers in the dermis and subcutaneous tissue. The treatment of typical RMH usually can be a simple excision. However, certain variant of acquired RMH presenting as a plaque on the chin tends to be difficult to be simply excised. To the best of our knowledge, there have been only two reported cases of plaque-type variant of acquired RMH in pubmed searching. A 22-year-old man presented with an asymptomatic erythematous indurated plaque on the chin. The lesion appeared 18 months ago and has shown recent increase of size. Incisional biopsy was performed on the chin and histopathologic finding showed mature striated muscle fibers interspersed haphazardly with collagen fibers and adipocytes in the dermis and subcutaneous tissue. The diagnosis of plaque-type RMH was made based on clinicopathologic finding. We recommended observation with regular follow-up because the lesion was too wide to be excised. We report an extremely rare case of plaque. type variant of acquired RMH and discuss its peculiar clinicopathologic features with the review of literatures.
