중년 이후 많은 환자들이 배뇨 후 요실금을 앓고 있지만 아직 적절한 치료가 이뤄지지 않고 있다. 몇 가지 병태생리학적 기전이 제안되었지만 우리가 주목한 기전은 구해면체근과 해면체 조직의 위축으로 인한 요도의 확장이었다. 본 연구의 목적은 해면체와 요도의 해부학적 변화를 관찰하여 배뇨 후 요실금의 기전을 규명하는 것으로 8주령의 SD 수컷 랫드 그룹과 24개월 이상 된 SD 수컷 랫드 그룹으로 나누었다. 전체 음경에 대한 구부요도 및 해면체 면적의 비율은 두 그룹 간 통계적으로 유의하였다(P<0.05). 평활근 함량과 배뇨 후 요실금의 기전(nNOS, α-SMA)과 관련된 매개변수는 두 그룹 간 유의한 차이가 있었으며(P<0.05), 본 연구의 결과는 배뇨 후 요실금 연구에 기여할 것으로 기대된다.

This study observes the difference in the actual regional ripple effect of the decrease in admission resources due to the decrease in school age population, which has been weak in empirical studies, and how much the decrease in competition rate by department nationwide provides a significant shock to the decrease in enrollment rate in the population unit. An empirical quantitative analysis was attempted. As a result of applying the panel-tobit regression model, a clear gap was confirmed in the decrease in the registration rate due to the decrease in the competition rate both nationally and in the provinces, and in particular, a highly significant relationship was derived with the decrease in the recruitment rate. In particular, the sensitivity of the risk of unrecruitment due to a decrease in competition rate was the highest in the Jeolla region (0.499), followed by the Gangwon region (0.475) and the Gyeongsang region (0.471), and the metropolitan region (0.158) was confirmed to be the most stable. This suggests that the gap in insufficient funding has gradually widened by region over the past 10 years, and that the shock wave becomes more pronounced in the provinces farther away from the metropolitan area. Based on this study, if we deviate from the standardized application of university development policies for the metropolitan area and regional universities, and present a customized higher education strategy for each region, it will be an opportunity to prevent local extinction due to a decrease in the school-age population and achieve coexistence with higher education institutions and regions at the same time.

폐림프관 평활근종증은 주로 가임기 여성에서 발병하며 점진적으로 호흡부전에 이르게 하는 드문 질환이다. 폐의 혈관, 림프관 그리고 기관지를 구성하는 평활근 세포의 비정상적 과오종성 증식으로 인해 기관지 폐쇄, 낭성 기포로의 변환, 림프관 폐쇄 등의 특징이 있으며 대부분 호흡곤란, 기흉, 기침, 흉통, 객혈, 유미흉 등을 동반한다. 호흡부전을 동반한 말기 페림프관 평활근종증은 페이식이 유일한 치료법으로 국내에서 시도된 적은 있으나 아직 성공사례에 대한 보고가 없었다. 본원에서는 폐림프관 평활근종증을 앓고 있던 말기 호흡부전의 40세 여자 환자에게 좌측 단일 페이식술을 시행하여 좋은 결과를 얻었기에 이를 보고하는 바이다.

The lymphangioleiomyomatosis(LAM) is a rare disorder, which afflicts mainly young woman of childbearing age, characterized by proliferation of immature smooth muscle cell in the lymphatics. We experienced a case of LAM in 26-years-old pregnant woman, confirmed pathologically by inguinal lymph node biopsy. She has suffered from exertonal dyspnea and dry coughing. The symptoms and chest X-ray were aggravated with pregnancy, but improved after delivery with two times of pregnancy. The chest X-ray showed diffuse reticulonodular infiltration and chest HRCT showed diffuse scattered tiny thin-walled cyst of lung parenchyma. We noted chylous ascites of which triglyceride level is 396 mg/dl. After delivery, the symptoms were getting better. We treated with medroxyprogesterone and planned close observation and follow-up.

This research investigated the present state of the dress forms used by clothing manufacturers and proposed procedure to bring out the standardized body type and figure for women in twenties. The result of questionnaire showed chief pattern maker's thoughts that dress form should be differently made for each age group and should be more reflected the standard body than the idea body. The standardized body type was made from the standardized posture and size which were analyzed from the interquartile range(IQR) of 314 subjects. The standardized size could be verified as for the balanced body shape of twenties through making the standard dress form. The standardized form(S form) was compared with three kinds of forms(A, K and P) for investigating the suitability of forms. K form was very similar to S form, Educational P form and manufacturer's A form had quite big differences from S form at the important areas for making clothing. The side shapes of A, K and P forms showed differences at back bending, neck angle and hip shape from S form. A form was comparatively smooth and flat. This results could be used as the practical standard to improve the suitability of size and shape in the dress forms of manufacturers and educators.

Post operative maxillary cyst may arise after the surgical treatment for maxillary sinusitis with the symtoms of swelling, pain, and pus discharge in the buccal region. It is examined by Waters' view, panoramic view and other intraoral radiographs, but quite variable radiologically. Most of the cyst is seen round or ovoid shape radiolucency, destruction, expansion and thinning of the lateral wall or posterior wall, and roots of the adjacent teeth may be resorbed. We studied about 117 cases of the post operative maxillary cysts which diagnosed in department of oral and maxillofacial radiology, Seoul National University Hospital. We analyzed and obtained following results. 1. These cysts occured more frequently in male than in female and the incidence is highest in the 4th and 5th decade. 2. Initial radical operation of maxillary sinus were performed mainly between the age of 10 and 45 years, and about 60% of the patients were 15 to 25 years. 3. Pain and swelling on buccal area, pus discharge, and toothache are most chief compaints, seven cases were found at routine examination without symtoms. 4. Most of these cysts were unilocular with smooth and well-defined border. 5. The majority of the cysts occurred in the anterolateral wall of maxillary sinus. 6. Dental changes of the lesional area were loss of lamina dura and root resorption, but about 55% were not changed.

A sleeve lobectomy is an appropriate operative procedure in patients with endobronchial neoplasms of low-grade malignancies in the proximal airways and for a small but significant number of patients with carcinoma. Here, we present eleven cases of sleeve lobectomy which were performed from 1984 to the August of 1991 in the Department of Thoracic Surgery of Seoul National University Hospital. The sex distribution was 6 males and 5 females in the age range from twenty to sixty seven, with an average of 44.9 years. The pathologic diagnoses were 7 cases of pulmonary malignancies: carcinoid in two, mucoepidermoid carcinoma in two, adenoid cystic carcinoma in one, adenocarcinoma in one, and squamous carcinoma in one. Other diagnoses were two cases of tuberculous bronchial strictures and two cases of benign tumors: one case of pesudolymphoma and one case of neurilemmoma. The procedures consisted of five right upper sleeve lobectomies [Fig. 1], four left upper sleeve lovectomies [Fig. 2], one left lower sleeve lobectomy[Fig. 3], and one right middle and lower lobetomy [Fig. 4]. All except one had a normal preoperative pulmonary function. The case which had a poor pulmonary function was a 66-year-old female adenocarcinoma patient. She seemed to be very intolerable to pneumonectomy [predicted FEV1=0.60L]. Therefore, she had a right sleeve upper lobectomy and experienced smooth postoperative course without any pulmonary problems. All cases had good postoperative results and no postoperative complications.

From March, 1985, to June, 1993, 244 patients with 345 episodes of spontaneous pneumothorax treated at Koryo General Hospital were reviewed. Most of the patients were male, and the ratio of male to female was 8:1. The average age of the patients with spontaneous pneumothorax was 32.8 years old. The site of pneumothorax was revealed left side in 53.3%, right side in 42.6%, and bilateral in 4.1%. The cause of pneumothorax were shown primary spontaneous pneumothorax in 73.4%, and secondary spontaneous pneumothorax in 26.6%. The underlying pathologic lesion in secondary spontaneous pneumothorax showed pulmonary tuberculosis in 56patients[86.1%], COPD in 4patients[6.2%], bronchial asthma in 2patients[3.1%], lung cancer in 2patients[3.1%], and pneumoconiosis in a patient[1.5%]. The usual clinical symptomes were dyspnea, chest pain and chest discomfort. Recurrence rate was as follow; 2nd episode 33.6%, 3rd episode in 26.8%, and above in 4th episode in 18.2%. All the patient of pneumothorax was treated as following; Closed thoracostomy tube drainage in 127patients, bullectomy in 88patients, lobectomy in 5patients, wedge resection in 2patients, conservative treatment with oxygen therapy in 21patients, and video assisted thoracoscopic bullectomy in a patient. The course of treatment of all of the patients were smooth and uneventful.
