Purpose: This is a descriptive study to investigate the relevance between biological nursing science subjects (structure and function of the human body (SFHB), mechanism and effects of drugs (MED), clinical microbiology) and examination workbook items for Registered Nurse Licensure Examination (RNLE) in Republic of Korea (ROK) and the United States of America (USA). Methods: RNLE 8 workbooks which were published by the Korean Nurses Association were utilized for analysis of Korean RNLE. Saunders comprehensive review for the $NCLEX-RN^{(R)}$ examination was used for analysis of US RNLE. The relevance between items in the standard syllabuses of biological nursing science subjects (SFHB, MED, clinical microbiology) and the RNLE items of these workbooks in ROK and the USA was analyzed. Results: The relevance rates of ROK and the USA were 3.6% vs 0.4% in SFHB, 8.9% vs 23.0% in MED, and 4.5% vs 5.8% in clinical microbiology. Conclusion: In SFHB, the relevance of the RNLE in ROK was higher than that of the USA. However in MED the relevance of the RNLE in USA was higher than that of the ROK. Since medications are one of major tasks of nurses, it is necessary to increase the number of related items in the RNLE in ROK.

The purpose of this study was to investigate the effects of vitamin E on the histochemical change of kidney tissue in diabetic rats. Sprague Dawley male rats weighing 100$\pm$10g were randomly assigned to one normal and three STZ induced diabetic groups, which were subdivided into vitamin E free diet(DM 0E group), 40mg vitamin E per kg diet(DM 40E group) and 400mg vitamin E per kg diet(DM 400E group). Vitamin E level of normal group was 40mg per kg diet. Diabetes was exper imentally induced by intravenous injection of 55mg/kg of body weight of streptozotocin(STZ) in citrate buffer(pH 4.3) after 4 weeks feeding of experimental diets. Animals were sacrificed at the 6th day of diabetic states. The contents of thiobarbituric acid(TBARS) in kidney were increased 119%, 84% and 33% in DM 0E, DM 40E and DM 400E groups, respectively, compared to normal group. That of DM 400E group was decreased 39% compared to DM 0E group. Content of 2 microglobulin in urine in DM 0E, DM 40E, and DM 400E groups were increased by 248%, 181%, and 164%, respectively, compared to normal group. The diabetic groups showed the regressive lesion such as renal tubule, intumescence of epithelial cell, vacuolization. The results of the observation through electronic microscope showed the mitochondria shape of proximal tubule epithelial cell, irregular array, increase of ribosome, and irregular arrangement of small villosity, etc. These types of changes appeared severer in DM 0E group than in DM 400E group. These results indicate that the TBARS productions on kdney in STZ induced diabetic rats were increased, consequently those leaded to damage of renal tubule and minuteness structure. But a large quantity vitimin E supplementation was suppressed in TBARS production and improved in peroxidative damage of renal tissue so that relieved degenerative changes of renal tubule epithelial cell.

This paper deals with numerical analyses in the context of estimations of hydrodynamic motions and dynamic loads for a floating type offshore platform using some exclusive simulation code such as code for the simulation of a floating type of offshore crane based on multi-body dynamics, along with the commercial code AQWA. Verifications of numerical models are carried out by comparing the RAO results from the simulation code. In the verification analyses, hydrodynamic motions are examined in the frequency domain for the floating type offshore platform according to the mooring lines. Both the hydrodynamic motions and dynamic loads are estimated for floating type offshore platforms equipped with the catenary type and taut mooring lines. A review and comparison are carried out for the numerically estimated results. The structural safety of the connection parts in an offshore structure such as a floating type offshore platform is one of the most important design criteria in view of fatigue life. The dynamic loads in the connecting area between a floating type offshore platform and its mooring lines are estimated in detail according to variations in the mechanical properties of the mooring lines. The dynamic tension load on the mooring lines is also estimated.

Author reviewed psychodynamics and psychoanalytic treatment of obesity. A variety of psychodynamics and unconscious conflicts have been described in obese patients : eating as a defense against depression, eating as a substitute for maternal love, obese body as a larger penis, and eating as a self-soothing. There was a gross neglect of certain normal parenting roles in obese family. The parenatal superego structure was not as perfectionistic. As with children and other patients with preoedipal pathology, in obese patients the analyst in addition to being transference object is a new and different object who promote healthy maturation. Because of obese parients, in there projective identification, can provoke intense countertransference, the analyst have to consider it. On the other hand, many analysts' countertransferences to superobese patients is that huge person recalls one's own childhood relationship with adults and bring forth a feeling of helplessness.

As smart environment is spread out in our living environments, the needs of an approach related to Human Computer Interaction(HCI) is increases. One of them is head pose estimation. it related to gaze direction estimation, since head has a close relationship to eyes by the body structure. It's a key factor in identifying person's intention or the target of interest, hence it is an essential research in HCI. In this paper, we propose an approach for head pose estimation with pre-defined several directions by random forest classifier. We use canny edge detector to extract feature of the different facial image which is obtained between input image and averaged frontal facial image for extraction of rotation information of input image. From that, we obtain the binary edge image, and make two accumulated histograms which are obtained by counting the number of pixel which has non-zero value along each of the axes. This two accumulated histograms are used to feature of the facial image. We use CAS-PEAL-R1 Dataset for training and testing to random forest classifier, and obtained 80.6% accuracy.

Most of oven range doors are opened from top to down. Feeling of door in case of home appliances including oven ranges affects the quality of product. The major factors to evaluate the feeling quality are opening force, closing force, and bouncing effect happened when the door is opened completely. If opening and closing forces become large, consumers may have complaints. If the bouncing effect becomes large, the impact can cause the body as well as the door to damage. Opening and closing forces, and bouncing effect must be minimized to improve the feeling quality. In this study, the mechanism which improves the existed dual compressive spring and cam structure is suggested by using nonlinear cam and spring. After the nonlinear cam is designed and manufactured for the suggested mechanism, this cam is confirmed to become more superior than the existed one by applying it to the practical oven range.

Optical and microwave remote sensing data have been widely used in land cover and land use classification. Thanks to the spectral absorption characteristics of ground object in visible and near infrared region, optical data enables to extract different land cover types according to their material composition like water body, vegetation cover or bare land. On the other hand, microwave sensor receives backscatter radiance which contains information on surface roughness, object density and their 3-D structure that are very important complementary information to interpret land use and land cover. Separate use of these data have brought many successful results in practice. However, the accuracy of the land use / land cover established by this methodology still has some problems. One of the way to improve accuracy of the land use / land cover classification is just combination of both optical and microwave data in analysis. In this paper for the research, the author used LANDSAT TM scene 127/45 acquired on October 21, 1992, JERS-1 SAR scene 119/265 acquired on October 27, 1992 and aerial photographs taken on October 21, 1992. The study area has been selected in Hanoi City and surrounding area, Vietnam. This is a flat agricultural area with various land use types as water rice, secondary crops like maize, cassava, vegetables cultivation as cucumber, tomato etc. mixed with human settlement and some manufacture facilities as brick and ceramic factories. The use of only optical or microwave data could result in misclassification among some land use features as settlement and vegetables cultivation using frame stages. By combination of multitemporal JERS-1 SAR and TM data these errors have been eliminated so that accuracy of the final land use / land cover map has been improved. The paper describes a methodology for data combination and presents results achieved by the proposed approach.

Purpose: Paragonimiasis is infectious disease occurred by Paragonimus Westermani, which invades into human body as a final host. Habitual eating the freshwater crab or crawfish unboiled is one of the reason of infection. Paragonimiasis raged in 1970s in Korea, Japan, China and other Asian countries but the incidence decreased rapidly. Once people eat infected second host, parasite penetrates the duodenal wall and migrates to the lung. During this migration period, the parasite can migrate to other organ, such as brain, spinal cord, liver and subcutaneous tissue, but the cases are rarely reported. The objective of our study is to present our experience of the ectopic migration of parasite to the subcutaneous tissue of the abdomen, which was easily treated with excision and Praziquantel medication. Methods: A 59-year-old woman who likes eating unboiled freshwater crab was diagnosed as Paragonimiasis 15 months ago. Her symptoms were fever and cough, and she was treated with Praziquantel medication. 3 months after discharge, she visited our hospital with left pleuritic chest pain, cough with fever, and palpable mass formation on left lower quadrant of the abdomen. Wedge resection of the left lung and Praziquantel medication was maintained for a week. Nevertheless, fever persisted after the treatment. The patient received total excision of the abdominal soft tissue mass, and the fever was relieved. Results: Pathologic findings of the mass showed multiple cyst and abscess formation with crystal structure which is suspicious parts of the parasite or calcified egg shells. Uncontrolled fever was relieved after the operation, and there was no evidence of recurrent Paragonimiasis and ectopic migration for 1 year follow up period. Conclusion: Ectopic migration of Paragonimus is rare, but multiple organ can be involved. Patient with Paragominiasis who was refractory in fever control after Praziquantel medication or surgical evaluation of the lung should be considered as ectopic migration of the Paragonimiasis.

The astronomical understanding of the heavens in "Hwangje-Naegyeong" can be divided into three main fields: the theory of cosmos, astronomy and calender. "Hwangie-Naegyeong" comprised the theory of cosmos, astronomy and calender established in the Han period. Astronomy was to describe the heavenly world and to interpret its phenomena. Calendar was to make numerical representations of the observations of all kinds of celestial bodies and to give them number-mystical meanings. Theory of cosmos treated what ancient Chinese speculated on the structure of the heavens including the earth. These three fields developed independently. However, they can also be be combined into one tradition, the astronomical knowledge. In the Han period that the astronomical knowledge grew from the mere accumulation of primitive knowledge to the established form. Throughout the Chinese history, the essential contents of astronomical knowledge including the theory of calendar, did not change much from what they were in Han period. "Hwangje-Naegyeong" use the lunisolar calendar(太陰太陽曆) and the Calendar in the late Han period(後漢四分曆). The use of the subdivisions of the seasons(24節氣) and the leap month(閏月) in "Hwangje-Naegyeong" means that it adopted the lunisolar calendar. Also "Hwangje-Naegyeong" adopted the Calendar in the late Han period by the four points: "Hwangje-Naegveong" ruled the circulation of the universe(周天度數) at 365, 1/4 terms, use the The Twenty Eight Constellations in astronomical observation, view the heavenly body by the ecliptic(黃道) and mark down year by the Heavenly Streams & Earthly Branches(干支紀年), The 24 solar terms is made by amount of Yang-Gi(陽氣) and samyum and samyang(三陰三陽) represent the amount of Yang-Gi in the earth.

Advanced fiber fabrics have been utilized in not only anti-stabbing and bullet-proofing for body armor but also various industrial fields including vehicular armor and spacecraft structure. Furthermore, there have been a number of research to improve the ballistic performance of advanced fabrics introducing many computational approaches. In our research, an advanced fabric, Heracron manufactured in South Korea was modelled firstly using Autodyn, a commercial software specializing in impact and explosion phenomenon. The sensitivity of the input parameters was also confirmed by conducting simulations. To verify the numerical modelling, we measured and compared the simulation results with velocity decrements after impact involving one, three, and five layers of Heracron under 200-500 m/s impacts by an aluminum spherical projectile. The Heracron fabric was successfully modelled using Autodyn.
