Purposes of this paper are focused on researching that employees in small and medium-sized construction company embraced green growth policy by Korean government's strong will and they have try to improve it to take advantage of strengths. Specifically, the purpose of this study includes: Firstly, to examine the effects of employee's cognition of green growth policy and their organizational commitment. Secondly, to examine the mediating and moderating effect of the policy trust and company trust between employee's cognition of green growth policy and organizational commitment. In addition, th examine the facilitating effect of employee's self-efficacy between company trust and organizational commitment. In order to verify the relationship, moderating and mediating effects, data were collected from 168 individuals in 19 small and medium sized company to test theoretical model and its hypotheses. Findings are as followed: first, the relationship between the cognition of green growth policy and organizational commitment is positively related. Second, the employee's company trust played as a partial mediator and moderator on the relationship between cognition of green growth policy and organizational commitment. Finally, employee's self-efficacy also played as a partial mediator on the relationship between company trust and organizational commitment. This study contributes to deepen our understanding of employee's organizational commitment by suggesting an alternative theoretical model regarding how the cognition of green growth policy and organizational commitment work to relate employee's company trust, and how the company trust and organizational commitment work to facilitate employee's self-efficacy. These results reveal that the study contributed to combining variables of employee's cognition of green growth policy, company trust, self-efficacy and organizational commitment, and expanded it.

In spite of the transitional changes in the shoe industry in Busan area, regular academic studies on the management plan to improve the practical competitiveness of footwear industry focused in the materials, bio-dynamics, components, and designs, etc. in the engineering viewpoint are very rare. Many reports of policies were published from late 190's to 2000's but they were limited to the identification of practical situations and the measures for strategic alternatives and were not developed to be the academic studies to improve the competitiveness in terms of management control. It is intended to seek for the measures to be reviewed as the alternatives to improve the self-competitiveness of footwear companies by approaching the problems limited to such specific area in the viewpoint of management control. The core of this study is to provide the alternative plans for expansion of the industrial foundation by seeking for the measures to improve competitiveness with application of knowledge management as an alternative for improvement of not transient but sustainable industrial competitiveness, in order to help the export of shoes from Busan area which has been rapidly increased since the Korea-USA FTA and Korea-EU FTA. In such viewpoint, in the study, a questionnaire survey was performed related with the issues of Busan's footwear industry and the plan to implement knowledge management was discussed for improvement of the competitiveness of footwear industry based on the result of such questionnaire survey. As most of studies and directions have been focused in functional shoes, designs, materials, and components, etc., which are related with the properties of human dynamics, as the alternatives for improvement of the footwear industry of Busan area and did not suggest the measures to make basic changes in the management of companies, the implementation of knowledge management was emphasized in order to seek for the direction of such plan. The purpose of this study is to suggest an alternative for construction of industrial eco-system for high added value by seeking for the probability of knowledge management for conversion of footwear industry into knowledge industry. In order to accomplish the effect of increased export as the result of FTA, current management method of footwear companies is limited and the effect of FTA should be maximized by improving the competitiveness with implementation of knowledge management methods. Settlement of such knowledge management will act as the momentum to improve the competitiveness of footwear companies and, in a long-term viewpoint, will be able to maximize the improvement of knowledge industry and creation of job opportunities.

The purpose of this study was to empirically verify the effect of social entrepreneurship on market orientation. total of 500 questionnaires were distributed to workers in social enterprise and preliminary social enterprise. 202 questionnaires were used for final validation of research model, The hypotheses set in this study were validated through SPSS18.0 and LISREL8.3 based on the research model. The results showed that all hypotheses were accepted, except for 5 hypotheses(Hypothesis 1-1, Hypothesis 1-2, Hypothesis 1-3, Hypothesis 1-6, Hypothesis 1-9). First, we examined the effect that empathy might have on market orientation in connection with social entrepreneurship. The results suggested that empathy did not have a statistically significant effect on customer-orientation, inter-department cooperation and coordination, and competitor orientation. Second, we examined the effect that innovativeness might have on market orientation in connection with social entrepreneurship. The results showed that innovativeness had a positive(+) effect on customer-orientation and inter-department cooperation and coordination but did not have a statistically significant effect on competitor-orientation. Third, we examined the effect that risk-taking might have on market orientation in connection with social entrepreneurship. The results implied that risk-taking had a positive(+) effect on customer-orientation and inter-department cooperation and coordination but did not have a statistically significant effect on competitor-orientation. Finally, the relationship among market orientation variables was like this: The inter-department cooperation and coordination had a positive(+) effect on both customer-orientation and competitor-orientation. The results of this study are expected to provide a useful basis for overall understanding about the effect of social entrepreneurship on market orientation and present important theoretical and practical implications.

Background : Drowning represents the third most common cause of all accidental deaths worldwide. Although few studies of submersion injury were done in Korea, the subjects were mainly pediatric patients. The purpose of this study is to describe the clinical feature of submersion injury in adults. Methods : The medical records of 31 patients with submersion injury who were >15 years of age and admitted to Kyungpook National University Hospital from July 1990 to March 2003 were retrospectively examined. Results : The most common age-group, cause, and site of submersion accidents in adults were 15-24 years of age, inability to swim, and river followed by more than 65 years of age, drinking, and public bath respectively. The initial chest radiographics showed bilaterally and centrally predominant distribution of pulmonary edema at lung base in about 90% of patients with pulmonary edema represented by submersion injury but at only upper lung zone in 10%. Eventually, 25 patients (80.6%) survived without any neurologic deficit and 2 patients (6.5%) with significant neurologic deficit, and 4 patients (12.9%) died. Age, arterial gas oxygenation, and mental status among baseline variables showed significant difference for prognosis. Conclusions : More than 65 year of age, drinking, and occurrence in public bath were relatively important in submersion injury of adults, and the successful survival of 80.6% of patients suggests that cardiopulmonary resuscitation should be intensively done in even adults.

Background : IGFBP-3 inhibits the mitogenic and anti-apoptotic activity of IGF by blocking the binding of IGF to its receptor. However, under certain circumstances, IGFBP-3 can enhance the activity of IGF by protecting IGF from its degradation. More than half of the interindividual variations in IGFBP-3 levels are known to be genetically determined by the polymorphism at -202 locus of IGFBP-3 gene. Method : We attempted to ascertain whether A-202C polymorphic variation of IGFBP-3 gene constitutes a risk factor for non-small cell lung cancer (NSCLC), using PCR-restriction fragment length polymorphism (RFLP). Our study included 104 NSCLC patients and 104 age-, gender-, and smoking status-matched control subjects. Result : In the 104 NSCLC subjects, the genotypic frequencies at the -202 site were as follows: AA = 67 (64.4%), AC = 35 (33.7%), and CC = 2 (1.9%). We did detect significant differences in the genotypic distribution between the NSCLC and the control subjects (p<0.05), and the NSCLC risk correlated significantly with AA genotype at the -202 locus (AA>AC>CC). Using CC genotype as a reference, the odds ratio (OR) for the subjects with AC genotype was 2.60 (95% CI: 0.89 - 8.60), and the OR associated with AA genotype was 5.89 (95% CI: 1.92 - 21.16). Conclusion : These results indicate that the dysregulation of IGF axis should now be considered as another important risk factor for NSCLC, and a potential target for novel antineoplastic therapies and/or preventative strategies in high-risk groups.

Background : The fact that only 10-20% of chronic cigarette smokers develop chronic obstructive pulmonary disease (COPD) reflects the presence of genetic factors associated with the susceptibility to COPD. Recently, it was reported that the surfactant protein A increases the secretion of matrix metalloprotease 9, which degrades extracellular matrices of the lung, through a Toll-like receptor 2 (TLR2). In this context, possible role of TLR2 in the pathogenesis of COPD was postulated, and a functional dinucleotide repeat polymorphism in intron II of TLR2 was evaluated for any association with COPD. Method : Male patients with COPD and male smokers with a normal pulmonary function were enrolled in this study. The number of Guanine-Thymine repeats in intron II of the TLR2 gene were counted. Because the distributions of the repeats were trimodal, the alleles were classified into three subclasses, 12-16 repeats: short (S) alleles; 17-22 repeats: medium length (M) alleles; and 23-27 repeats: long (L) alleles. Result : 125 male patients with COPD and 144 age- and gender-matched blood donors with a normal lung function were enrolled. There were no differences in the distribution of each allele subclass (S, M and L) between the COPD and control group (p=0.75). The frequencies of the genotypes with and without each allele subclass in the COPD and control group were similar. Conclusion : A microsatellite polymorphism in intron II of TLR2 gene was not associated with the development of COPD in Koreans.

Anderson(1937), Power and Barnes(1941) reported a study concerning a method of tubal sterilization in association with peritoneoscopy or laparoscopy in which they cauterized the tubes. There appears to have been a hiatus of interest in sterilization (cold or hot) associated with laparoscopy until reintroduction by Palmer(1963), Frangenheim(1964) and Steptoe(1967). On the other hand, for interval female sterilization, however, minilaparotomy is relatively new. By Saunder and Munsick(1972), John Lyle(1974), Frank Stubb(1974), Vitoon(1973) and B.C. Bai(1975), their own technique for interval female sterilization requires 2.0 to 2.5cm, incision at the margin of the mons pubis. In Korea, female sterilization by means of minilaparotomy firstly reported by B.C. Bai using Bai's uterine elevator, of his own device, early in 1975. Recently inteval female sterilization by laparoscopy and minilaparotomy are widely accepted throughout the world especially in Asian countries. Minilaparotomy is carried out from 1974, laparoscopic sterilization from 1976, and in this study each of 250 cases of those were analysed and discussed for the comparison at Seoul Red Cross Hospital. (1) In the age distribution, numerous clients were in their age of $31{\sim}35$ in laparoscopy as well as minilaparotomy. Average 33.7 years in L and 33.2 years in M. (M=minilaparotomy, L=laparoscopic sterilization) (2) As regarding living children, women having 3 children represented the greatest number, 113 cases out of 250 in M group and 102 cases out of 250 in L group. Average No. of child are 2.9 in Land 3.1 in M. (3) Concidering the operation day in the menstrml cycle, the greatest number of cases, those who underwent tubal sterilization during the days of $26{\sim}$, next during the $6{\sim}10$ days of the cycle in both group. (4) Concidering the operation time, 188 cases by laparoscopy were performed in $6{\sim}10$ minutes, 33 cases within 5 minutes and 24 cases in $11{\sim}15$ minutes. Maximum 50 minutes, minimum 4 minutes and average 8.3 minutes. The majority of cases (154 cases) by minilaparotomy required $6{\sim}10$ minutes and 67 cases $11{\sim}15$ minutes, 6 cases within 5 minutes. Maximum 30 minutes, minimum 4 minutes and average 10.4, minutes. In both groups, most of the reasons for the extra length were surgical difficulties such as thick abdominal wall, pelvic adhesion, less cooperation of patients in early period of this study. (5) Hospital stay after operation in L group required $3{\sim}4$ hours in 125 cases, $2{\sim}3$ hours in 41 cases, $4{\sim}5$ hours in 32 cases out of 250. Maximum 8 hours, minimum 1 hour and average 3.8 hours. In M group hospital stay required $6{\sim}7$ hours in 100 cases, over 7 hours in 85 cases, $5{\sim}6$ hours in 46 cases and so on. Maximum 14 hours, minimum 2 hours and average 6.5 hours. (6) The time between operation and gas passing in the majority cases of both groups, were $12{\sim}36$ hours. A veragetime 20.3 hours in L and 27.2 in M. (7) Laparoscopic sterilization coincident with induced abortion were carried out in 27 cases, laparoscopy with minilaparotomy to control for mesosalpingeal hemorrhage in 1 case. Minilaparotomy coincident with induced abortion were performed in 65 cases, D and C whit polypectomy, menstrual regulatian, and remaval of IUD in 1 case respectively. (8) In L group, 1 case of mesosalpingeal hemorrhage, 1 case of abdominal wall infection were complicated during operation. In M group, 1 case of uterine perfaration, 1 case of abdominal wall infection, 1 case of hemorrhage from omentum and 1 case of bloody vaginal discharge were complicated. No intensive medical treatment was required for those minor complications in both groups. (9) No failure has been recognized and these two sterilization techniques might be the simple, safe and the most effective method for permanent contraception at present time. There is no significant clinical defference between L and M group in this study.

There are numerous reports on the relative risk of pelvic inflammatory disease among the users versus the nonusers of intrauterine device. Reported relative risk varied from no difference between the two groups to 3-9 fold increase in the users. In an attempt to define this relative risk of pelvic inflammatory disease and related microorganisms ,pelvic organ observation and bacteriological study were done through laparoscopy. Specimens for microbiologic culture were obtained simultaneously from the fallopian tubes via laparoscopy and from the endocervix via regular pelvic examination method. The study population was consisted of 30 I.U.D.users and 35 J.U.D.nonusers who visited the Yonsei University Severance Hospital and the Sung-Ga Hospital for laparoscopic sterilization. The results obtained were as follows: 1. There was no difference in age distribution, economic status and numbers of parity and abortion between I.U.D. users and I.U.D. nonusers. 2. The pelvic inflammatory findings were noted on laparoscopy in 2 cases of I.U.D. users, with an incidence of 6.6%. And no pelvic inflammatory finding was noted in any of the nonusers,but this difference was not statistically significant (p>0.005). 3. All the bacteriologic culture of the specimens from the fallopian tubes of both groups yielded negative results. 4. The bacteriologic culture of the spec imens f rom the endocervix revealed more frequent isolation of possible pathogen such as Hem ophilus ,alpha-Streptococcus ,Corynebacteria, Bacteroides in the I.U.D.users than in the nonusers.But,this difference was also not statistically significant (p>0.005).

Background : Pleural effusions with high amylase levels are reported frequently in patients with pancreatic diseases, a rupture of the esophagus and a malignancy. However, there is no data available on the clinical features of an amylase-rich pleural effusion in Korea. This report describes the causes of the high amylase levels in a pleural effusion and analyzes its association with malignancy. Methods : The records of patients with an amylase-rich pleural effusion who were assessed at the Gyeongsang National University Hospital from January 1998 to August 2002 were examined retrospectively, and the distribution of amylase levels in those patients, the causative diseases, and the histological type in the case of a malignancy were analyzed. Among the 532 patients whose pleural effusion was evident on a chest X-ray, there were 36 cases with an amylase-rich pleural effusion. The amylase levels were determined by an enzyme method (Hitach 747 autoanalyzer). Results : Of the 36 patients with an amylase-rich pleural effusion, there were 18 patients(50%) associated with a malignancy, 8 patients(22%) with a parapneumonic effusion, 7 patients(19%) with pancreatic disease, and 3 patients with other causes. The amylase level in a pleural effusion due to pancreatic disease was much higher than that due to other causes(p<0.01). Among the malignant pleural effusions with high amylase levels, the origin of the malignancy was a primary lung cancer in 13 cases and metastatic lung cancer in 5 cases. The histological types of malignant causes were adenocarcinoma in 10 cases(56%), squamous cell carcinoma in 2 cases(11%) and unknown type of carcinoma in 6 cases. The amylase level in the adenocarcinoma cases was much higher than that in the other cell type carcinomas(p<0.01). There was no significant association between the amylase level and the glucose level among the malignant cases with amylase-rich pleural effusion(p=0.21). Conclusion : The most frequent cause of an amylase-rich pleural effusion was a malignancy. Primary lung cancer and adenocarcinoma were the most common malignancies and histological types associated with a malignant pleural effusion with high amylase levels. The amylase level in a pleural effusion secondary to pancreatic disease was much higher than from any other causes.

Introduction : Diffuse interstitial lung diseases (DILD) comprise of a large group of lung diseases with diverse etiologies. They are classified into four categories based on the etiology and pathological findings. In Korea, epidemiological data on DILD has never been reported in a prospective manner. Method : From May 2002 to April 2004, total 487 patients with DILD were prospectively registered at Samsung Medical Center. The prospective observational analysis of the etiologies, its classification based on 2002 ATS/ERS (American Thoracic Society/European Respiratory Society) guidelines, as well as diagnostic tests and the retrospective analysis of the treatment modalities were carried out. Any infectious and malignant causes were excluded. Results : 1) The patients were classified into idiopathic interstitial pneumonia (IIP) in 269 patients (55.2%), known causes of DILD in 168 patients (34.5%), sarcoidosis in 27 patients (5.5%), other forms of DILD in 14 patients (2.9%), and undetermined DILD in 9 patients (1.9%). 2) The diagnostic test showed that most patients had undergone chest high resolution computed tomography (HRCT) and pulmonary function test (PFT) (97%, 89%). Transbronchial lung biopsy (TBLB) and surgical lung biopsy (SLB) were performed in limited patients (38%, 29%). 3) Among 269 patients with IIP, 220 (82%) had idiopathic pulmonary fibrosis (IPF) while 23 (9%) had nonspecific interstitial pneumonia. SLB was carried out in 36% of patients with IIP. 4) Symptomatic supportive care was given to 67% of IPF, but specific medical treatment including corticosteroids was administered to 89% of non-IPF patients. Conclusion : A nationwide registry of DILD patients is required to determine the annual incidence, etiology, and practice pattern of diagnosis and treatment in Korea.
