This study is conducted to apply the insight of Johnson and Libecap(1982) to Korea's coastal vessel fishing. According to Johnson and Libecap(1982) the differences in fishing ability are largely attributed to acquired knowledge and innate skills. Since those skills are unlikely to be readily transferable assets, economic rents exist in the fishery, even under open access conditions. Therefore the paper tries to examine whether the acquired information from fishing experience and innate skill could also have an effect on catch variation of coastal vessel fishing in Kyung-Nam province. To do so, the paper is performing the analysis by establishing econometric model. Results show us that the acquired information from fishing experience have a significant effect on catch variation, but the innate skill does not.

Our study was carried out to develop the severity-adjustment model for length of stay in hospital for community-acquired pneumonia so that we analysed the factors on the variation in length of stay(LOS). The subjects were 5,353 community-acquired pneumonia inpatients of the Korean National Hospital Discharge In-depth Injury Survey data from 2004 through 2006. The data were analyzed using t-test and ANOVA and the severity-adjustment model was developed using data mining technique. There are differences according to gender, age, type of insurance, type of admission, but there is no difference of whether patients died in hospital. After yielding the standardized value of the difference between crude and expected length of stay, we analysed the variation of length of stay for community-acquired pneumonia. There was variation of LOS in regional differences and insurance type, though there was no variation according whether patients receive their care in their residences. The variation of length of stay controlling the case mix or severity of illness can be explained the factors of provider. This supply factors in LOS variations should be more studied for individual practice style or patient management practices and healthcare resources or environment. We expect that the severity-adjustment model using administrative databases should be more adapted in other diseases in practical.

This study aimed to find an effective intervention measure through establishing the correlation between self-regulation (control over life style) and height growth through neuro-feedback training. 40 elementary students in grades two to four with height growth programs (20 experimental group students, 20 control group students) were examined for the changes before and after undergoing neuro-feedback training. The experiment lasted for three months with one 30-minute training session two times a week. After analyzing the differences in self-regulation among the control group with no neuro-feedback training and the experimental group with neuro-feedback training, the differences in height growth were analyzed. First of all, there were positive changes in self-regulation of the experimental group compared with the control group. Secondly, the experimental group showed larger changes in height growth. In conclusion, neuro-feedback training had positive effects upon the self-regulation that adjusts the acquired factors of height growth, which led to positive effects.

Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula are acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection(prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis), obstruction (stricutre, impacted stone, Cunningham clamp or condom catheter) and trauma(instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and infection. These calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors. 1) a ureteral or bladder calculus that is lodged in the urethra, 2) urethral trauma or stricture, 3) calcification around a foreign body or hair. The treatment of urethral diverticulum conbined with stone is excision of the diverticula with removal of stone. We treated two cases of urethral diverticulum combined with stone in the male, and report with review of literature.

There are two types of organizational knowledge in terms of its creation process: experiential and analytical knowledge. The experiential knowledge is created by repetitive experiences of an individual or team through task execution, while the analytical knowledge is acquired by analyzing accumulated data or information in the organization. The experiential knowledge often remains tacit or implicit in the organization because it is primarily acquired at an individual or team level. Therefore, the issue on the experiential knowledge is to share it actively within the organization. On the other hand, the analytical knowledge is explicit in its nature since it is extracted from data or information. Thus, it is important to guide a systematic creation of the analytical knowledge rather than encourage to share it. The current trend of "knowledge management" mainly focuses on the experiential knowledge - know-how, idea, case, etc - and neglects another important knowledge in the organization. i. e., analytical knowledge. This paper tries to shed a new light on the "knowledge management" arena by introducing rather new perspective in the concept of knowledge. The purpose of this study is to identify the factors affecting the analytical knowledge creation in the organization. We conducted an exploratory case study of three companies with a previously defined research framework and found some critical factors for the analytical knowledge creation. They are "organizational resource", "effectiveness of feedback process", "data source management", and "experimental mind set". Finally, we proposed research model and propositions regarding the analytical knowledge creation in the organization.

Background : Acquired tracheoesophageal fistula(TEF) results mostly from Prolonged tracheal intubation and insertion of nasogastric tube. Although the incidence has decreased since the usage of low pressure, high volume cuff of endotracheal tube, it is seldom cured spontaneously and needs surgical treatment. Material and Methods : We have retrospectively reviewed five cases of TEF who underwent surgical treatment for cure from March, 1990 to September, 2001 and analyzed the cause, treatment, postoperative complications and prognostic factors. Results : Majority were men(80% : 4 of 5 patients) and the mean age was 29.4 years old(range, 11-58). The most predominant etiology was prolonged intubation or tracheostomy(80% : 4 of 5 patients) and 3 of 5 patients were treated by tracheal resection and end to end anastomosis with primary closure of esophagus. Postoperative complications occurred in 4 patients the most common complications were wound infection(4 cases) and esophageal leakage(2 cases). Extubation was done on postoperative day 11.5(range, 1-33) days, and factors causing delayed extubation were status esophagus. epilepticus, edema, and tracheal stenosis. Conclusion : Spontaneous closure of TEF is seldom possible and the surgical treatment of choice is tracheal resection and end to end anastomosis with primary repair of the esophagus. preoperative pulmonary rehabilitation and early extubation postoperatively are important factors for success.

Purpose: This study aims to identify factors influencing the stigma communication concerning HIV (Human Immunodeficiency Virus)/AIDS (Acquired Immune Deficiency Syndrome) patients between health and medical college students. Methods: In this descriptive study, the participants were 158 college students from a certain university. Data were collected from September 18 to September 30, 2018. Self-reported questionnaires were used to measure AIDS-related knowledge, homosexual awareness, fear of HIV/AIDS patients and stigma communication. The collected data were analyzed with descriptive statistics, an independent t-test, one way analysis of variance, Pearson's correlation and a stepwise multiple regression analysis using the SPSS 23.0 program. Results: The factors influencing the stigma communication between health and medical college students were a fear of HIV/AIDS patients (β=.47, p<.001) and homosexual awareness (β=-.15, p=.040), which together explained 28.0% of the variance in the model. Conclusion: The study findings suggest that an education program for health and medical college students should be developed. Additionally, when designing the education program, it is recommended that the contents for inducing attitude changes should include affective areas as well as knowledge-oriented contents. The study suggests that it is necessary to provide a systematic education program to decrease the stigma for HIV/AIDS patients before health care providers enter clinical practice.

Objective: The purpose of this study was to analyze correlation effect size between Basic Psychological Needs (BPN) and factors affecting BPN. Methods: This research was reviewed and synthesized systematically by meta-analyse. Fifty-eight published studies between 2008 and 2016 were sampled and the effect sizes were acquired. Results: The major findings were as follows. In general, medium correlation effect sizes were found. Competency among sub-factors of BPN showed highest effects. Parental factor was more related to BPN than school and individual factors. Parenting behavior and family psychological backgrounds were the most crucial factors in the parental factors. School adjustment was the most critical factor in the school factors. In school grade, the elementary school was more related to BPN than junior high school and high school. Conclusion: Based on these results, we suggest a number of components for parent-education programs, and information for future research.
