A survey was conducted on 222 students in two elementary schools in rural areas, one was a rural small city and the other was in the countryside. By measuring their skin-foldness in 4 spots by caliper, the body fatness of 5 grades(BFGr) of the subjects was resulted as follows ; 28.0% of boys and 6.7% of girls were classified as obese the and 34.1% of boys and 31.1% of girls as overweight. Comparing by region, children in the small city seemed to be fatter than the ones in the countryside(21.7% vs. 17.2% as obesity). Comparing by gender, boys were fatter than girls(28.0% vs. 6.7% as obesity). When recategorizing body fatness from 5 grades(BFGr) into 3 groups(BFGp) as overweight group(obesity+overweight), normal and underweight group(underweight+severe-underweight), we observed no significant difference in childrens dietary habits and food intake frequencies by BFGp. Overweight and underweight groups enjoyed snacking before dinner more frequently than the normal group(42.1-59.3% vs. 31.5%). The subjects showed poor nutrition knowledge score with relatively high attitude score about weight control and dietary behavior score was a little lower than the attitude score. Nutrition education programs, like camps, should stress on childrens nutrition knowledge. BFGp related to obesity attitude positive, a very low level and the latter related to diet, exercise and fasting attitudes at positive levels. Therefore overweight children seemed to be motivated easily. Also the higher the in exercise-value score, the more increased was shown in exercise attitude at positive, very low level. Emphasizing exercise-value in camp programs might make childrens exercise attitude more positive. As strategies for a rural obesity camp program are being developed by obese and non-obese children. The camp would be held over summer vacation for 3 days(2 nights) at the participants expence not exceeding 50,000 won. Contents of the program cover nutrition knowledge, and exercise-value as well as cooking lessons, exercise practice, and self-esteem enhencement.

Recently many hospitals in Korea have become interested in JCI (Joint Commission International) accreditation. As the medical market opens to medical tourism and to attract foreign patients, JCI accreditation has become the prime object. It is compatible with government policy for upgrading the medical industry and necessary to strengthen compatibility with foreign hospitals. JCI accreditation means that the medical services provided by a hospital are equivalent in quality and patient safety to medical services internationally. It also means that the hospital is reliable in treating patients according to international policies and regulations. The most important meaning of JCI accreditation is that the staff in the hospital have promised to provide safe patient care according to the hospital policies and bylaws made and approved by the staff members. During the process for JCI accreditation, the hospital staff's concept regarding patient safety has been changed and many of them are now voluntarily involved in quality improvement and patient safety activities in the hospital.

PURPOSE: To predict pulmonary arterial hypertension by comparing the extent of honeycombing lesion with the diameter of main pulmonary artery (MPA). MATERIALS AND METHODS: We retrospectively reviewed 21 patients (20 men, one woman) who showed honeycombing lesion on HRCT, and also analysized a control group of 30 (29men, one woman) who had no cardiopulmonary symptom and no abnormality on chest CT. On Chest HRCT, we scanned at four levels [1)aortic arch, 2) bifurcation of bronchus, 3) mid-portion of left ventricle, 4) dome of right diaphragm], and two radiologists then evaluated the proportion of honeycombing lesion within the entire lung field. According to the extent of this, we divided the patients into five groups [<20% (I), 20-39% (II), 40-59% (III), 60-79% (IV), > or = 80% (V)], and then divided Group I into two subgroups [<10 % (I|1), 10-19% (I-2)]. Using contrast-enhanced routine CT, the main pulmonary artery (MPA) was measured at its the widest diameter perpendicular to the long axisat the level of its bifurcation. RESULT: In group I (n=11) MPA was 28.4+/-2.6mm ; in group II (n=6), it was31.7+/-2.0mm ; in group III (n=2), 33.5mm ; in group IV (n=1), 33mm ; and in group V (n = 1), 39mm. In subgroup I-1MPA was 26.1+/-1.9mm, and in subgroup I-2, it was 29.8+/-1.6mm. In the control group, MPA was 25.1+/- 2.0mm. CONCLUSION: The extent of honeycombing lesion is closely related to the change in diameter of the MPA. Honeycombing lesion extending over more than 10% of the lung field may lead to pulmonary arterial hypertension.

An attempt has been made to discriminate synaptic diversity in the neostriatum of the cat with emphasis on the characteristic structures of axon terminals and postsynaptic profiles. The differentiation of the axon terminals was based on the size and shape of synaptic vesicles in the axoplasm. Three types of axon terminals could be differentiated: Type I, the terminals contained small round (45 nm in diameter) vesicles; type II, the terminals with large pleomorphic (50 nm) vesicles; and type III, the terminals contained flattened (45 x 25 nm) vesicles. The type I terminals were making asymmetrical or symmetrical synapses in contact with the somata, dendrites and dendritic spines of neurons in the neostriatum, and a few type I terminals making asymmetrical or symmetrical contact with axons were also observed. The type II and III terminals were making symmetrical contact with the somata and dendrites of neostriatal neurons. A few type II terminals formed at the node of Ranvier of myelinated nerve fibers were making symmetrical contact with large dendrites. Additionally, dendro-dendritic and serial syanpses were rarely found in the neostriatum. In the serial synapses composed of axo-dendritic and dendro-dendritic synapses, the type I terminals making asymmetrical contact and the type II making symmetrical contact were identified.

The incidence of postspinal headache is one of the well known complications of spinal anesthesia. Several factors such as needle size, bevel direction, multiple dural puncture and previous history of postspinal headache were thought to influence the incidence of postspinal headache. This studies were done to see the effect of needle size (22 and 25 gauge needle) and needle bevel direction (parallel, vertical, oblique insertion to the longitudinal dural fiber) on the incidence, duration, severity and location of spinal headache in the 548 patients underwent spinal anesthesia. The following results wre observed: 1) Neither needle size nor needle bevel direction had effect on the incidence of severity, duration and location of postspinal headache. 2) The ineidence of headache was 8.8% (48 cases), 3) The onset of headache was 1~2 day (67%) and duration of headache was 4~5 day (85%) in postanesthetic day. 4) The severity of headache was mild and moderate in 77% cases. 5) In the half cases, headache was relieved by means of bed rest alone.

PURPOSE: The dual-specificity phosphatase PTEN/ MMAC1/TEP1 has recently been identified as the tumor suppressor gene most frequently mutated and/or deleted in human tumors. However, PTEN mutations have rarely been detected in sporadic thyroid cancers. Therefore, this study investigated the PTEN expression of thyroid cancer and the relationship between PTEN, clinical status and other biologic factors such as HER-2/neu and p53. MATERIALS AND METHODS: The study samples consisted of 62 thyroid cancer specimens and 24 benign thyroid tumor specimens from patients who were operated on the Department of Surgery, Uijongbu St. Mary's hospital during the 5 years from January 1995 until January 2000. All tumors were studied by immunohistochemical staining using monoclonal antibodies against PTEN, HER-2/neu and p53. The results were analyzed statistically. RESULTS: PTEN protein was found to be under-expressed more frequently in thyroid cancers (29%) than in benign thyroid tumors (4.2%). The reduction in PTEN expression in thyroid cancers was not significantly related with the recorded clinical factors such as size, age, lymph node metastasis and p53, except for HER-2 which was found to be significantly related (p=0.001). HER-2 over- expression was noted in thyroid cancer (83.8%) more frequently than in benign tumors (16.7%). CONCLUSION: This study has demonstrated that the under-expression of PTEN protein and the over-expression of HER-2 protein may play a role in the carcinogenesis and development of thyroid cancer.
