This study presents a comparative analysis of enforcement and regulatory compliance issues in Korean and American fisheries. The comparison involves characterizing factors which affect regulatory compliance. The study also suggests policy directions and strategies by characteristics of factors suitable to Korean fisheries circumstances in order to induce voluntary compliance from fishers and to make compliance friendly environment for the fishers. In detail, this study has 3 steps as follows. First, this study characterizes factors influencing compliance and non - compliance caused by various reasons and categorizes these factors by considering theories for fisheries regulatory compliance. Major categories of compliance factors consist of fisheries resources, users(fishers), and the government. Each category is composed of several factors and sub - factors by characteristics. Second, this study seeks to diagnose problems and limitations from the regulatory compliance in Korean and US' fisheries by analyzing the current status of the compliance in both countries. The comparative analysis between two countries highlights the problems and limitations of each country's regulatory compliance and leads to implications for Korean fisheries. Third, this study suggests policy directions and strategies suitable to Korean regulatory compliance environment through detailed understanding of U.S.' fisheries regulatory compliance. The suggested strategies are based on the concept of voluntary compliance and compliance - friendly environment, not command and control regulations. Furthermore, this study provides policy suggestions for Korean fisheries regulatory enforcement and compliance issues.

In this paper, we propose a correction method for astronomical telescope using recursive least square method. There are two ways to move a telescope : equatorial operation and altazimuth operation. We must align polar axis of a equatorial telescope with the north celestial pole and adjust the horizontal axis of a altazimuth telescope exactly to match the celestial coordinate system with the telescope coordinate system. This process needs time and expertise. We can skip existing process and correct a tracking error easily by deriving the relationship of the celestial coordinate system and the telescope coordinate system using the proposed correction method. We obtain the coordinate of a celestial body in the celestial coordinate system and the telescope coordinate system and derive a transformation matrix through the obtained coordinate. We use recursive least square method to estimate the unknown parameters of a transformation matrix. Finally, we implement a telescope control system using a microprocessor and verify the performance of the correction method. Through an experiment, we show the validity of the proposed correction method.

Purpose : The purpose of this study was to identify effects of virtual reality-based closed kinetic chain (CKC) exercise on lower extremity muscle activity in chronic stroke patients Methods : Subjects were assigned randomly either to VR+CKC exercise group (n=15) or the CKC exercise group (n=15). When the study began, both groups received conventional physical therapy five times per week. The VR+CKC exercise group received virtual reality programs and the CKC exercise group received close kinetic chain exercises. Each exercise program was performed for six weeks (5 times per weeks; 20 minutes per time). Participants were measured on lower extremity muscle activity using EMG. Results : There was a significant increase of muscle activity (%RVC) in vastus lateralis and vastus medialis. Conclusion : In this study, the virtual reality-based closed kinetic chain exercise program was an effective exercise for improving lower extremity muscle activity in chronic stroke patients.

DNJ concentration in silkworm, Bombyx mori was traced through the life. DNJ absent in egg existed over the concentration of 5 mg gdw-1 from 1st instar to 4th day of 5th instar during larva period. DNJ concentration decreased drastically with body weight about at 7-8th day of 5th instar when silk production became a major process. (omitted)

The development of cDNA microarray has permitted the analysis of thousands of genes simultaneously. cDNA microarray has been used to analyze gene expression profiles during developmental stage in both single and multicellular organisms. Two significant factors contributing to the limitation of the development of cDNA microarray in the Bombyx mori are the shortage of accessible repositories of cDNA clones and ESTs and the relative scarcity of facilities to produce microarrays and analyze the data generated.

$Fe_2O_3,\;Ag_2O,\;CaWO_4$ and $Gd_2O_2S$:Tb loaded on titanium dioxide photocatalysts (P25, Degussa) were prepared by a calcination. Their composite films containing water-born polyurethane used as a material for immobilization were obtained by spray coating technique. The photocatalytic activity of the titanium dioxide films was characterized by decrease of UV-vis absorption spectra for methylene blue and gas chromatography for photocatalytic decomposition of formaldehyde diluted in water. It was shown that the $Gd_2O_2S$:Tb modified titanium dioxide films had good photocatalytic properties and followed the first-order kinetic model with regard to photocatalytic decoloration of methylene blue. Especially in formaldehyde photodegradation experiment, decrease rate of concentration of the titanium dioxide films with $Gd_2O_2S$:Tb modifying was about 35% larger than that of the unloaded titanium dioxide film.

Purpose: This study was to assess the prevalence of workplace bullying and the relationship workplace bullying to self-esteem and turnover intention among clinical nurses. Methods: The subjects were 223 clinical nurses at 3 small and medium-sized hospitals in K and B cities. The data were collected from February 1st throughout 28th, 2013. The collected data were analyzed using the SAS program through the frequency, percentage, mean, and Pearson's correlation coefficients. Results: The rate of self-reported bullying in the nursing workplace was 24.6% of respondents. There was a negative correlation between workplace bullying and self-esteem (r=-.39, p<.001). Also there was a positive correlation between workplace bullying and turnover intention (r=.14, p=.031). Conclusion: Prevalence of self-reported bullying is high among small and medium-sized hospitals and is clearly associated with lower levels of self-esteem and higher levels of turnover intention. Therefore, an organizational nursing management program as a monitoring regularly the psychosocial work environment and policies and procedures to prevent and manage workplace bullying is strongly recommended for the promotion of self-esteem and reducing the nurse's intention to leave the organization.

The result of the previous work leads to the idea that the inner area of the hyperbolic shell generator should be minimized for the cooling tower with higher first natural frequency. In this study the inner area of the hyperbolic shell generator was graphically established under varying height of the throat and angle of the base lintel. From the graph, several shell geometries were selected and analysed in the aspect of the natural frequency. Three representative towers reinforced differently due to different first natural frequencies were analysed non-linearly and evaluated using a damage indicator based on the change of natural frequencies. The results demonstrated that the damage behaviour of the tower reinforced higher due to a lower first natural frequency was not necessarily advantageous than the others.

Annular pancreas is a rare congenital anomaly with the descending duodenum encircled by a ring of pancreatic tissue, which may cause partial or complete obstruction of the duodenum. In newborn, the symptoms can be those of duodenal stasis resulting from partial intestinal obstruction secondary to some degree of duodenal stenosis. A male newborn weighing 2.0 Kg was born by C-section delivery at 37 weeks' gestation to a 27-year-old mother who had a hydramnios. He was in relatively good condition at birth except regurgitation of saliva and intermittent apnea. A plain film of the abdomen showed the double-bubble of gas filled stomach and proximal duodenum, and upper gastrointestinal series showed a dilated proximal duodenum, with a complete obstruction of the descending duodenum. Intraoperative finding revealed encirclement of the duodenal second portion by pancreatic tissue. Duodenojejunostomy was performed. After the operation, he had developed two serious complications, neonatal septicemia by Enterobacter cloacae on postoperative day 12 and systemic candidiasis on postoperative day 19, and been managed with ventilatory support, antibiotics, and antifungal agents with recovery.
