Hypoparathyroidism is usually the result of an inadvertent surgical removal of all the parathyroid glands, In some instances, not all the tissues are removed, but the remainder undergoes vascular supply compromise secondary to the fibrotic changes in the neck after surgery, Previously, the surgery for hyperthyroidism was the most frequent cause of acquired hypoparathyroidism. Idiopathic hypoparathyroidism is a relatively rare disease that is characterized by hypocalcemia and hyperphosphatemia due to a parathyroid hormone deficiency of an unknown cause, It usually develops at a young age, and shows various clinical symptoms and signs accompanied with hypocalcemia. In addition, it is rarely associated with polyglandular autoimmune syndrome during the follow-up. Hypocalcemia and idiopathic hypoparathyroidism associated with labor and lactation are rarely reported condition previously. We here describe a case of a woman in whom the symptomatic severe hypocalcemia appeared after her delivery. We reviewed all the previously reported cases and suggest a possible physiological explanation for the association between pregnancy, lactation, and the appearance of symptomatic hypocalcemia.

Convulsive disorder is the most part of the pediatric neurologic disease. As far as the treatment of convulsive disorder concerned, we must consider familys' understanding, and the close cooperation between the epileptic child, parents, and doctors. We compared to Kim's report in 1985, to study the change of parents of epileptic children thinking. A prospective study was undertaken the analysis of 100 epileptic children parents visited to the pediatric dept, of Soonchunhyang university hospital from May to July, 1995. Psychological assessment, questionnaires which contains 17 items were given them, and these items were compared to Kims report in 1985 The results were as follows: 1) Parents of epileptic children answered convulsive disorder has influenced to children growth and development( 60.8% in 1985, 65.0% in 1995 ). 2) For asking the causes of children disease, 40.5% of them in 1985 and 50.0% of them in 1995 answered to uncertain, but only 7.8% of them in 1985 and 7.0% of them in 1995 answered to relation with familial inheritance. 3) The feelings at time of the diagnosis were gloomy or uncomfortable: 52.3% in 1985, 38.0% in 1995 and shameful 28.1% in 1985, 9.0% 1995. parents had belived in the epilepsy was treatable disease: 41.0% in 1995. 4) According to the this survey, patients explained reasons why their children take the medication increased from 23.5% in 1985 to 65.0% in 1995. 5) Only family, knew that their children had the convulsive disorder about 50.3% in 1995 and 22.0% in 1995. Family, patients and other people except family knew that their children had the convulsive disorder about 6.5% in 1985 and 43.0% in 1995. 6) The parents opinion and expectation toward the medical doctors were that they wanted to get full explanation for the disease 81.0% in 1985 and 35.1% in 1995, and others were explantation about toxicity and side effects of the medication and advises for the childrens life and activities.

In this study, thermal diffusion caused by using air cooled condenser at LNG power plant in Yulchon was simulated through in numerical method (Matsuno scheme). The input data of model was used to seasonal wind components (u, v) of automatic weather system (AWS) and seasonal temperature ranges between inflow and outflow of opening air. The aim of this study was twofold : (1) to investigate sensibility analysis of thermal diffusion coefficient : (2) to simulate diffusion of heat source through the calculated effect height for season and stability variations. These sensibility analyses were performed in detail using two case studies one is to apply horizontal and vertical thermal diffusion coefficient as 50 m-ls-1 and 10 m-ls-1, the other is 30 m-ls-1 and 10 m-ls-1 respectively. It is well known that the sensibility for thermal diffusion coefficient is low owning to very similar results. Consequently, thermal diffusion for the first case is simulated by using effect height for season and stability variation. The temperature is under 1℃ at surface whereas that is high at near the center of effect height.

The data were obtained through a number of senior and junior students at Cheju national university in December 2007. From the gathered information, which resulted in 202 responses that have been used in the study, were analyzed by frequency using SPSS/PC 12.0 program. The result of this study are the following : First, we need to provide practical education to help the student employment and to increase the interest in major by strengthening the major training course. Second, we need to provide various information related to employment around the country. Most students gain career information from their friends and seniors, and mass media, not from school. The thoughtful consideration of finance and policy is requested which can offer systematic information in school, in order that they may easily adapt themselves to their environment. Third, various career counseling programs need to be developed and applied to each student according to their leaming stages. The field of support is increase of job preparation education, english education, strengthening the major training course and the interview training course. Fourth, we need to develop various programs considering necessity and specific of each college. Fifth, it need to be aproached the career guidance according to their gender. Women's needs of job-seeking were very intensive but their preparation level is relatively low. Colleges' career support system and organization utility were uneffective because their programs were not specified for women, It is important to offer various counsel and guidance to women. Sixth, a professor of college needs to increase career counsel with their students, It is important to job-seeking of students. In addition, the limitations of the study and possible follow-up projects are proposed in the conclusion section.

The purpose of this study was to investigate the effect of knee exercises on the onset times of vastus medialis oblique muscle (VMO) and vastus lateralis muscle (VL) and in healthy subjects. Fifteen subjects (7 men, 8 women) in a mean age of 25.4 years participated in the study. Electromyographic (EMG) signals were recorded from the VMO and VL under four exercises. Knee exercises consisted of open kinematic terminal knee extension, straight leg raising, isometric hip adduction exercise, and closed kinematic terminal knee extension. No significant differences were found in the onset times of EMG activities of VMO and VL in the four exercises. There were also no significant differences among the exercises. These results coincided with previous studies that found no difference between onset of VMO and VL. However, it is difficult to say that there is no difference between onset of VMO and VL in healthy subjects. To confirm this results, further researches that follow same onset determination metod and exercises are needed. Not only is the study of onset time of muscle needed, but also the studies of the amount of activation and the rate of increase of muscle activation are needed.

Eleven phenols including two chlorophenols, eight alkylphenols and bisphenol A were derivatized with isobutylchlomformate to form their isobutoxycarbonyl derivatives. Standard phenol mixture was concentrated for the isebutoxycarbonyl (isoBOC) derivatization and analysed by gas chromatography/mass spectrometry (GC/MS). The recoveries of the derivatization method of alkylphenols, chlorophenols, and bisphenol A were calculated by gas chromatography/mass spectrometry -selected ion monitoring mode using two work-up methods for comparison; shaking and heating method. The linear detector responses were obtained in the concentration range of 5 -400 ng, with correlation coefficients varying from 0.9755-0,9981. Recoveries of the alkylphenols, chlorophenols, and bisphenol A were determined by gas chromatography /mass spectrometry -selected ion monitoring mode using two work-up methods for comparison; the US-EPA method and the isoBOC derivatization method. Eleven phenols in water samples were extracted with dichloromethane and then concentrated. Also, solid-phase extraction (SPE) with XAD-4 and subsequent conversion to isobutoxymbony derivatives for sensitive analysis with the selected ion-monitoring (SIM) mode. The recoveries were 85.1~109.9% and 90.3~126.6% for the US-EPA method and the isoBOC derivatization method, respectively. The method detection limits of bisphenol A for SIM were 0.732 ㎍/ℓ and 0.002 ㎍/ℓ for the two methods above, respectively.
