외래 유전자를 이식하여 형질전환동물을 생산하는 방법은 현재 약 3가지 정도가 실제 이용되고 있다. 현재 가장 많이 사용되고 있는 방법으로는 DNA 미세주입법인데 생쥐와 비교하여 다른 동물에서의 형질전환효율은 상당히 낮은 것으로 나타나 형질전환가축의 생산을 위해서는 많은 비용과 시설 및 노동이 필요하여 실용성에 문제를 갖고 있다. 각 가축에 적합한 DNA 미세주입 조건을 확립시키고 형질전환동물의 생산효율을 높이는 연구가 필요하다. 가축에서 형질전환기술이 실제로 응용되고 있는 분야로는 대량생산이 어려운 의약품을 형질전환가축의 젖으로 합성 분비시키게 함으로써 생리적으로 활성이 있는 의약품의 대량생산이 가능할 것으로 예상된다. Growth Hormone이나 Growth Factor들을 이용한 성장과 관련된 형질전환가축의 기술은 예상했던 것보다 큰 성과는 없었는데 이식 유전자의 과잉발현으로 인한 부작용으로 실용화될 수 없었다. 그러므로 형질전환동물의 실용화를 위해서는 효율적인 유전자 이식방법의 개발과 이식 유전자의 발현으로 인한 부작용을 최소화하면서 좋은 표현형을 얻을 수 있도록 이식유전자의 발현을 인위적으로 조절할 수 있는 regulatory system의 개발과 가축의 경제형질에 관여하는 유전자의 식별이 필요하다.

Purpose : Early identification of developmental disabilities allows intervention at the earliest possible point to improve the developmental potential. The Ages and Stages Questionnaire (ASQ), a parent- completed questionnaire, can be used as a substitute for formal screening tests. The purpose of this study was to evaluate the validity of the Korean version of the ASQ (K-ASQ) as a screening tool for detecting developmental delay of young Korean children in the setting of a busy pediatric outpatient clinic. Methods : Parents completed the K-ASQ in the waiting room of the pediatric outpatient clinic of St. Mary's Hospital, Catholic University Medical College. Out of 150 completed the ASQ, 67 who were born term and had no previous diagnosis of developmental delay, congenital anomalies, or neurological abnormalities were enrolled. The cut-off values of less than 2 standard deviations (SD) below the mean for the ASQ were used to define a "fail", and children who failed in one or more domains tested were classified as "screen-positive". Diagnosis of developmental delay was made when the developmental indices fell below -1 SD of the Bayley Scales of Infant Development-II. Results : (1) The mean age of children was $16.4{\pm}7.4$ months. Ten children (14.9%) were small-for- gestational age infants. The mean birth weight and gestational age were $3.1{\pm}0.6kg$ and $38.8{\pm}1.4$ weeks. Nine children (13.4%) were twins and 33 (49.0%) were male. The mean maternal education in years was $13.6{\pm}2.4$, and 31.3% had full-time jobs. The time for completing the ASQ was $10.2{\pm}3.0$ minutes. (2) Seventeen children (25.4%) were classified as screen-positive, four of them were delayed in development. Among eight children diagnosed with developmental delay, four were screen-positive and the other four were screen-negative by the ASQ. (3) The test characteristics of the ASQ were as follows: sensitivity (50.0%); specificity (78.0%); positive predictive value (23.5%); negative predictive value (92.0%). Conclusion : The high negative predictive value of the K-ASQ supports its use as a screening tool for developmental delay in the setting of a pediatric outpatient clinic.

From February 1996 to May 1997, 18 patients underwent mitral valve repair for mitral regurgitation. There were 9 male and 9 female patients aged from 19 to 68 years(mean, 53). Thirteen patients were in New York Heart Association(NYHA) class III and IV. The cause of mitral regurgitation was degenerative in 12 patients, rheumatic in 5 patients and infective in 1 patient. Fifteen patients were in Carpentier's functional classification II, 2 patients in Carpentier's class III and 1 patient in Carpentier's class I. Surgical procedures included prosthetic ring annuloplasty(16 cases), rectangular resection of posterior leaflet(15 cases), chordal shortening(5 cases), triangular resection of anterior leaflet(2 cases), commissurotomy(2 cases), partial transposition of posterior leaflet(1 case). These procedures were combined in most patients. There was no operative death. These patients have been followed from 1 to 15 months, mean of 6.7 months. There was one late death resulted from low cardiac output following mitral valve replacement. The function of the repaired valve in other 17 patients has remained satisfactory during the observed interval. We consider that mitral valve repair is highly satisfactory in patients with mitral regurgitation.

The stone artifacts in Bronze age from the Sinsongri sites in Seosan, Korea were studied on material characteristics and provenance presumptions. The use and rock names of the artifacts are a stone before processing, two semifinished stone arrowheads and a grinding stone plate by slates. In addition, there is semifinished stone arrowhead by andesitic rocks. The slate could be observed easily around the site, and the andesitic rock could be confirmed typical occurrences of the all kinds of rocks around the Kanwoldo and Hwangdori, Anmyun area above 10km from the site. As a result of analysis which is comparing between stone artifacts and same kinds of raw material rocks, the stone artifacts made by slates have similar lithology and geochemical characteristics however, the stone artifacts made by andesitic rocks are found a some different part of characteristics to the same kind of raw material rocks. Comparing of major, rare earth, compatible and incompatible elements about stones artifacts made by slates and by the same kinds of raw material rocks have same geochemical patterns. However stone artifacts made by andesites and the raw material rocks are confirmed some differences of geochemistry. Therefore the slate stone artifacts in Sinsongri site suggest that these are domestic-type which are made of the rocks around the site, and it was understood that the andesitic stone artifacts are foreign-type which need to get more geological survey and study about different volcanic artifacts of the site around the area.

The studies were carried out to develop an urban forest aromatic bath in the idle space within city area for handicapped persons, patients and city workers, who having less chance to visit the natural forest aromatic bath. The environmental conditions were checked in the experimental double vinyl house where native and exotic aromatic woody and herbaceous plants were growing with minimum energy input in the periods of mid-winter and mid-summer. The growth and photoperiodic responses of the plants to the low and high temperatures were observed during winter and summer respectively. The most of herbaceous plants in the double vinyl house with the controlled minimum night temperature of $-2^{\circ}C$ had no winter injury but did not grow and started the growth in April. The exotic herbs such as Catnip faassen's(Nepeta x faassenia) and Lemon bergamot(Monarda citriodora) grew better in the longer photoperiodic conditions. The growth rates of Abies koreana, Thuja koraiensis and Pinus sylvestriformis in the early spring were affected mainly by the night minimum temperature and less affected by the photoperiodic conditions during winter. The native aromatic herbs such as Robdosia japonica, Molsa punctulata, Agastache rugosa and Codonopsis lanceolata showed stimulatory growth at the 16 hours day-length in case of the high temperature vinyl hose. The height and root collar diameter growth of pine seedlings were inhibited in maxim temperatures over $40^{\circ}C$ during summer.

The concept of innate immunity in insects which refers to the first line of host defense constitutes the humoral and cellular components which are involved in recognition and actively participate in the elimination of the intruding foreign micro- or macro-organisms. Several recent studies suggest that juvenile hormone (JH) modulates the cellular immune reactions in response to pathogen. In this study, pyriproxyfen (a JH agonist as an insect growth regulator) was tested in its any inhibitory effect on the immune reactions of the beet armyworm, Spodoptera exigua. To this end, five different hemocyte morphotypes of final instar S. exigua were identified by phase contrast microscopy. Plasmatocytes and granular cells, which constitute about 90% of the total hemocyte count, were prominently distinguished based on their basophilic/acidophilic nature using Giemsa stain. The role of pyriproxyfen on the functional ability of hemocytes was analyzed using FITC-labeled Providencia vermicola for the phagocytic potential of the hemocytes. Both granular cells and plasmatocytes exhibited phagocytosis behavior. Pyriproxyfen significantly inhibited the phagocytosis of both cell types, proposing its novel action as an immunosuppressant.

Malignant mesothelioma has been considered a uniformly fatal disease associated with a median survival of 4 to 18 months. However, a multimodality approach toward therapy may Increase the length of palliation when a maximal resection of tumor is achieved. Recently we have experienced a 49 years-old male patient who had d ffuse malignant mesothelioma. The patient has complained of blood-tinged sputum and right chest pain for several months. Chest x-rays and CT scans showed compact haziness in the right entire thorax with massive bloody elusion, diffuse pleural thickening and collapsed underlying lung. We performed extrapleural pneumonectomy, and postoperative chemotherapy with cisplatin and mltomycin (Memorial Sloan-fettering Cancer Center method) was done. We are observing him for months now and there is no evidence of local recurrence.

Objectives:The present study investigates the status of inpatient psychiatric consultations at a general hospital in order to find factors that contribute to treatment compliance related to psychiatric consultations. Methods:The subjects were 333 patients who were hospitalized at Korea University Medical Center Ansan Hospital from 1 September 2009 to 31 July 2010.The patients were referred for psychiatric consultation during hospitalization. This study investigates demographic data, request department, referral causes, requestor, psychiatric history and diagnosis, andpsychiatric treatment compliance. Treatment compliance was defined as whether or not the patient had accepted psychiatric treatment during hospitalization or outpatient department(OPD) follow-up. This study ascertains the factors that have impact on compliance, by taking binary logistic regression with compliance and other variables. Results:Among the patients that were offered psychiatric treatment during hospitalization(N=310), treatment compliance was 82.9%. Among the patients that were offered OPD treatment(N=111), compliance was 55.8%. Elderly group(>65 years) showed better compliance to treatment during hospitalization than the younger patient group(OR=4.838, p=0.004). Patients with secondary psychiatric disorders showed better OPD follow-up compliance than patients with secondary psychiatric disorders(OR=8.520, p=.008). Conclusion:Elderly patients showed better compliance for psychiatric treatment during hospitalization. However they commonly have disorders such as delirium and mood disorders that have impact on the patient's physical state, hence further active measures should be carried out. Patients referred due to primary psychiatric disorders showed poor OPD compliance. Therefore clinicians have to suggest multidisciplinary interventions that will improve treatment compliance of such patients.
