  • From May 1988 to December 1995, 77 patients underwent surgical re ection for primary non-small cell lung cancer at GNUH, and were evaluated clinically. There were 65 males and 12 females(M:P=5.4:1), and the peak incidence of age was 6th decade of life(44.5%). The major symptoms were cough, hemoptysis and chest pain due to anatomical effects of the mass. Histopathologically, squamous cell carcinoma was 81.8%, adenocarcinoma 14.3%, and adenosquamous carcinoma 3.9% . There was no significant difference in survival among three groups. The pneumonectomy was performed in 26 cases(33.8%), lobectomy 30 cases(38.9%), bilobectomy 9 cases(11.7%), and overall resectability was 84.4%. The postoperative official stagings were as follows ; 26 patients of stage I(34%), 14 patients of stage II(18%), 22 patients of stage IIIa(29%), 14 patients of stage IIIb(18%), and one patients of stage IV(1%). In all cases, 3 year survival rate are showed stage 183%, stage II 26%, stage IIIa 17%, and stage IIIb 0%.

  • Soft-tissue expansion is a new surgical technique of providing donor tissue in modern reconstructive surgery. This technique provides a quantity of tissue of similar color, texture, and hair-bearing qualities for reconstruction of adjacent defects. It is known that the expanded skin shows several constant histologic changes including the increase in collagen fibers and vascularity within dermis, and thinning of subcutaneous tissue and dermis. In this study, the author observed serial histologic changes of rabbit skin induced by progressive tissue expansion upto excessive expansion of 6 times. The results are as follows : 1. Changes in the thickness of the epidermis was minimal until 3 times of expansion, but slight thinning was observed at excessive expansion state. 2. The thickness of the dermis was progressively decreased, and collagen fibers in the dermis was rapidly increased in early phase of expansion. 3. The vascularity in the dermis was also progressively increased. 4. The skin appendages showed no structural changes even in excessive expansion. 5. The panniculus carnosus showed no atrophic changes and the thickness was maintained in excessive expansion.

  • The objectives of this study were to investigate soil chemical properties for forest rehabilitation and suggest design and management in abandoned coal mine areas in Mungyeong, Gyeongsangbuk-do. Total study sites were 10 sites, and soil analysis particular were soil pH, TOC, total-N, C/N ratio, A.v. $P_2O_5$, and CEC. Because most of study sites showed soil pH from 5.0 to 7.0, it seems that soil pH does not affect growth of vegetation. But soil pH in Danbong1 was acidic (pH 4.6), so it is needed to improve with ameliorant such as limestone. Most of study sites is necessary to manage for organic matter and Nitrogen, because there sites showed lower value of TOC and total-N than general forest. The values of A.v. $P_2O_5$ and CEC were good in most of study sites, so it seems that they do not have effect on vegetation growth. All of soil factors has no regression according to elapsed time after rehabilitation. TOC, total-N and A.v. $P_2O_5$ among soil properties have positive relationship between each other. It is necessary to fertilizer for organic matter and Nitroge because of value in TOC, total-N and C/N ratio. The results of this study were analyzed only one time. So, long-term monitoring for soil properties is important for the correct forest rehabilitation and management.

  • The pulmonary giant cell carcinoma is classified as a variant of a large cell carcinoma and is diagnosed by the minimum component of 10% huge, pleomorphic and multinucleated giant tumor cell and emperipolesis of the neutrophils into the tumor cells. This tumor is characterized by local recurrences and early metastasis with extremely short patient survival. However, there are some reports that state that the survival time was extended by the operative resection and postoperative adjuvant chemotherapy and radiotherapy. A 46-year old male was admitted with complaint of hemoptysis for 2 months. Through chest X-ray and chest CT, a 5cm sized mass was found in the apical segment of the right upper lobe. During the preoperative evaluation, stenotic lesion in the left anterior descending coronary artery was found and treated by percutaneous transarterial coronary angioplasty. Four weeks later, right upper lobectomy was performed and the mass was proven to be a giant cell carcinoma. The patient received adjuvant chemotherapy and radiotherapy.

  • 한국산 천연수정은 보석장식용으로서는 그 품질이 이미 알려져 있으나 수정진동자로서의 특성에 관해서는 아직 보고된 바가 없다. 본 연구는 특히 경상도일대에서 채굴되고 있는 천연수정을 채집, 선별, 가공하여 그 수정진동자로서의 사용가능성을 실험을 통하여 검토한 것이다. 필자들은 채굴현장 근처에서 채집한 원석을 특별히 고안제작된 검사경을 이용하여 분석선별하였으며 X-ray를 사용하여 AT-cut로 orientation 한후 시판을 절단하였다. 다음 적용하여 전기적, 광학적 쌍수상태를 검토하고 다시 선별하였다 Dimensioning은 5MHz를 목표로 하였는데 연잠제를 사용하여 5MHz의 조도까지 연마하고 전극으로서 표준형의 은막을 부착하여 시판을 완성하였다. 시판을 대한 측정결과는 모든 등가정수가 대표적인 수입수정판의 것과 대등하였으며 특히 Q는 모두 105를 넘었다. 온도특성도 AT-cut의 이론치와 대차가 없었으며 -20℃-+100℃ 범위에서 최대 20PPM 이내의 편차를 보였다. 즉, 한국산 천연수정은 적절히 선별, 가공 한다면 부유한 수정진동자의 원재로서 사용할수 있음이 증명되었다. Samples of domestic natural quartz were collected and screened optically and chemically, and, after weeding out portions unfit for electrical resonator, were cut into AT-cut wafers, which in turn were dimensioned, trimmed and lapped into 5MHz resonator units. The results of measurements obtained from the specimens indicated excellent electrical characteristics of domestic natural quartz with the average Q quotient of 10s or higher. Temperature characteristics also showed typical AT-cut corves with the frequency deviation of 20PPM at maximum throughout the range of -20 to 100℃. The experiment on the initial batch of samples amply indicates the excellent electrical quality of domestic natural quartz as quartz resonator units.

  • Asplenium septentrionale (L.) Hoffm., belonging to the family Aspleniaceae, was recently recorded for the first time in Gyeongsangbuk-do, Uljin-gun, Buk-myeon, Docheon-ri. This species is distributed in Northern America, Europe, and Asia. This species, which is related by taxa of Asplenium, is distinguished in that it possesses a leaf blade that is more or less dichotomously divided, forked 1-2(-3) times, and narrowly linear (5- 20 mm length) sori. The newly given Korean name, 'Sol-ip-go-sa-ri' reflects the presence of a linear leaf similar to Korean pine needles. A description of the key characteristics, an illustration, and photographs of the habitats of this plant are provided in this report.

  • Background; Post-intubation injury is known to be the most common cause of tracheal stenosis. Treatment strategy for tracheal stenosis varies accoring to the extent of pathologic lesion. Focal mucosal lesion can be treated with laser photoablation, but full thickness tracheal lesion should be treated with resection and anastomosis. Material and Method; From Aptil 1998 to May 1999, twelve patients suffering from tracheal stenosis as a complication of endotracheal intubation were managed by resection and end-to-end anastomosis in the Department of Thoracic and Cardiovascular Surgery, Gyeongsang National University Hospital. Result; There was no operative mortality. Five temporary vocal cord paralysis and one wound infection occurred as early complications. During 18 months of follow-up, re-stenosis was not found. Conclusion; Tracheal resection and anastomosis can be considered as an excellent surgical treatment for tracheal stenosis which developed as a complication of endotracheal intubation.

  • This paper aims to explore the innovation milieu of red-pepper agro-industry in Bonghwa County, in the northern part of Gyeongbuk Province, and suggest policy recommendations for bringing up local agro-industry from a cluster perspective. It turns out that the capabilities of Bonghwa red-pepper agro-industry to innovate are remarkably weak let alone soft infrastructures such as learning networks between innovation agents and social capital. In this sense Bonghwa red-pepper agro-industry can be viewed as an agricultural area simply specialized in production sector rather than a kind of agro-industry cluster. For moving up Bonghwa red pepper industry into an innovative cluster, the paper suggests that the policy makers need to focus on cultivating local learning communities, building a region-wide incorporated brand, promoting the local agricultural technology centre as a network hub of cluster and fostering the functional links between universities and local innovation agents, covering farmers, agricultural organizations, agro-food producers and the local government.

  • Stone cultural heritages quantitatively as well as qualitatively occupy a large proportion in the designated heritages in Korea. The Stone Buddha statue in the Gulbulsa temple site, designated as the No. 121 treasure in 1935, is located in the southwestern slope of Mt. Sogeumgang, Dongcheon-dong, Gyeongju-si, Gyeongbuk Province and Buddhist images are sculptured on four sides of a 3.5m-tall gigantic rock. The damage states result from the weathering degree and indicate high correlation with the water contents. The water contents in the Stone Buddha of Gulbulsa temple site are highest at the east side and then decrease in order of north, south and west sides. These are proportional to the durations of sunshine. Moreover, the Stone Buddha of Gulbulsa temple site with dense joints, repaired areas and vegetated areas by lichens shows high water contents and damage states.
