Objectives : This study was peformed to identify the risk factors related to the development of hypertension in a rural area. Method : Total of 3,573 subjects in Chung-Song County were interviewed and examined in 1996. The study cohort comprised 2,580 hypertension-free subjects aged above 20. One-year follow up was completed for 1,781 subjects(69.0%) in 1997. General characteristics(age, gender, education level, economic status, marital status), the family history of hypertension, diet, alcohol, smoking, coffee, stress, past history of oral contraceptive and menopausal status in female, height, weight, waist and hip circumference, baseline blood pressure, and serum total cholesterol were considered as risk factors. Results : Multivariate analysis using logistic regression model indicated that age(RH=1.50, 95% CI; 1.15-1.96), the family history of hypertension(RR=2.11, 95% CI; 1.04-4.26), waist-hip ratio(WHR) (RR=2.09, 95%, CI; 1.15-3.79), and baseline systolic blood pressure(130-139/<120mmHg)(RR=3.34, 95% CI; 1.47-7.60) were significant risk factors associated with the development of hypertension above the borderline level in male. In female, age(RR=1.06, 95% CI; 1.03-1.09), change in menopausal status$(no{\rightarrow}yes/no{\rightarrow}no)$ (RR=3.32, 95% CI; 1.01-10.87), baseline systolic blood pressure(120-129/<120mmHg: RR=2.00, 95% CI; 1.02-3.90)(130-139/<120mmHg: RR=2.64, 95% CI; 1.34-5.20) and baseline diastolic blood pressure(85-89/<80mmHg)(RR=4.09, 95% CI; 1.86-8.96) were identified as risk factors. Conclusions : Age and high normal blood pressure were significant risk factors for the development of hypertension above the borderline level. In addition, the family history of hypertension and WHR in men, and the change of menopausal status in women might be significant risk factors in Korea.

The conclusion for this paper is as following as to plan for advancing security. First, Depending on situation, security martial arts technique is necessary in security work, but the case that the client need to be covered by security guards to avoid the danger often happens. If there is no self-sacrifice and loyalty to the clients, the meaningful security work is not completed in this situation. Therefore, the basic views on education of security leaders need to be defensive than aggressive, and be spirit-equipped than technical feature. Second, more time has to be taken training mentality along with focusing on technical education of security martial arts. To escape from danger spreaded around, security guards must be strong mentally and physically, then they are able to finish the situation. If someone is chosen as a security guard, one's physical strength is already approved. This means that the rest part for the perfect accomplishment is strict discipline on mental one's mind, and basically physical training has to be continued. In conclusion, The elements that the instructor has to acquire are not only extensive theoretical knowledge of the security martial arts and real experiences through techniques but also personality cultivation which maximize the morality training. Accordingly, this could bring the client personally change in perception of the security guard, furthermore greatly expand the academic and professional security work of security department.

Purpose: Adaptive statistical iterative reconstruction (ASIR) technique is a reconstruction method of CT image using statistical noise modeling which is known to reduce image noise and to preserve image quality despite reducing radiation dose. The aim of this study is to evaluate images using ASIR on bone SPECT/CT which is primarily performed in our hospital. Materials and Methods: We compared the images of applied ASIR (ASIR level: 20-80%) and none ASIR by changing the mA based on 120 kVp, 100 mA using Discovery NM/CT 670 (GE, U.S.A). First, we evaluated attenuation correction in SPECT image by changing the ASIR level using Anthropomorphic phantom. Second, we compared the contrast to noise ratio (CNR), image noise and spatial resolution in CT image using ACR phantom. Third, after selecting the ASIR level applicable patient using lower torso phantom, we examined 2 patients who followed up bone SPECT/CT and we performed blind test. Results: The degree of attenuation correction in SPECT image showed no significant difference between applied ASIR and none ASIR (P>0.05). When applied ASIR, the noise of CT image were reduced at least 17 up to 52% by changing the mA. The CNR of image with ASIR was maintained more than 0.8 at 40 mA (ASIR 60%) while those without ASIR showed 0.42 at standard 40 mA. In comparison of the high contrast object, we distinguished 12 line pairs/cm at 40 mA regardless of appling ASIR. Comparison of the patients image applied ASIR level 60% (40 mA) which found out by spine image of lower torso phantom showed no signigicant difference between applied ASIR and none ASIR in blind test. The CTDIvol and DLP for applied ASIR 60% showed decreased by 60%, 60% on average than using standard mA. Conclusion: The study show that the radiation dose in SPECT/CT using ASIR can be reduced despite degradation of SPECT and CT images. In addition, higher ASIR level could be possibly applied characteristics of SPECT/CT that region of interest is limited to bone.

Currently, cultivation of mushrooms using the Information and Communication Technology (ICT)-based smart farming technique is increasing rapidly. The main environmental factors for growth of mushrooms are temperature, humidity, carbon dioxide (CO₂), and light. Among all the mentioned factors, currently, only temperature has been maintained under automatic control. However, humidity and ventilation are controlled using a timer, based on technical experience.Therefore, in this study, a Pleurotus eryngii first-generation smart farm model was set up that can automatically control temperature, humidity, and ventilation. After installing the environmental control system and the monitoring device, the environmental condition of the mushroom cultivation room and the growth of the fruiting bodies were studied. The data thus obtained was compared to that obtained using the conventional cultivation method.In farm A, the temperature during the primordia formation stage was about 17℃, and was maintained at approximately 16℃ during the fruiting stage. The humidity was initially maintained at 95%, and the farm was not humidified after the primordia formation stage. There was no sensor for CO₂ management, and the system was ventilated as required by observing the shape of the pileus and the stipe. It was observed that, the concentration of CO₂ was between 700 and 2,500 ppm during the growth period. The average weight of the mushrooms produced in farm A was 125 g, and the quality was between that of the premium and the first grade.In farm B. The CO₂ sensor was in use for measurement purposes only; the system was ventilated as required by observing the shape of the pileus and the stipe. During the growth period, the CO₂ concentration was observed to be between 640 and 4,500 ppm. The average weight of the mushrooms produced in farm B was 102 g.These results indicate that the quality of the king oyster mushroom is determined by the environmental conditions, especially by the concentration of CO₂. Thus, the data obtained in this study can be used as an optimal smart farm model, where, by improving the environmental control method of farm A, better quality mushrooms were obtained.

There is a growing demand for agrometeorological information that end-users can use and not just interesting information. lo achieve this, each region/community needs to develop and provide localized climate and weather information for growers. Additionally, provide tools to help local users interpret climate forecasts issued by the National Weather Service in the country. Real time information should be provided for farmers, including some basic data. An ideal agrometeorological information system includes several components: an efficient data measuring and collection system; a modern telecommunication system; a standard data management processing and analysis system; and an advanced technological information dissemination system. While it is conventional wisdom that, Internet is and will play a major role in the delivery and dissemination of agrometeorological information, there are large gaps between the "information rich" and the "information poor" countries. Rural communities represent the "last mile of connectivity". For some time to come, TV broadcast, radio, phone, newspaper and fax will be used in many countries for communication. The differences in achieving this among countries arise from the human and financial resources available to implement this information and the methods of information dissemination. These differences must be considered in designing any information dissemination system. Experience shows that easy across to information more tailored to user needs would substantially increase use of climate information. Opportunities remain unexplored for applications of geographical information systems and remote sensing in agro meteorology.e sensing in agro meteorology.

As the number of online game user has been rapidly increased thanks to the recent vitalization of online contents market, not only new business opportunity but also the opportunity to create high profits have been provided as well. However, the increase of the number of online game user and the rapid expansion of the market evoke a cutthroat completion among online game service providers, and also high barriers to entry to online game market have been erected. Thus, what kinds of efforts need for the business success and sales increase in online game market? In lots of researches regarding online contents business, the deepening of loyalty was considered as a critical factor for the business success. According to the study on user's behavior in online environment, users would experience the Flow while using online service, and then, if they were in state of the Flow, they would use the service constantly. High customer loyalty to online game means high will to use the online game too. The purpose of this research was i) to examine what factors enable users to be naturally immersed in online game while playing it, ii) to examine what properties of online game can make game more interesting and exciting, iii) to verify that such factors are critical in deepening customer loyalty, and iv) to suggest some essential factors to be fun and exciting games, on where the focus should be put, and the directionality for the development for sales expansion of online game developer or online game service provider. The research results are as below: First, the involvement and the perceived quality which were characteristics of brand appeared to be factors most affecting Flow. This shows that once game user get interested in online game that user has played frequently, even though new games are released, user will continuously flow the game not moving to new games, and also shows that users not only get more interested but also put more trust in games in the site to where users are frequently going than games in other sites, and consequently user can increasingly flow the game. Second, the compensation and graphics which are the characteristics of contents appeared to be factors affecting Flow. Proper compensation which is given to game users triggers fun and interests in game and makes them flow more and more. And graphics make users to feel game space as if real space and let them flow in game with more reality. Third, challenges, support, and the stability which are technical characteristics appeared to be factors affecting Flow. Challenges enable users to not only experience new virtual world but also solve various difficulties and obstacles. Once users feel fun and interests through this challenge, they can naturally flow games. In addition, the stability of network provides reliability in security and hacking. By doing so, it can induce users to flow more and more. Lastly, when aforementioned characteristics including contents characteristics, technical characteristics, and brand characteristics are organically combined each other, game users feel fun and total minutes are naturally increased, so that game users experience Flow, and consequently the customer loyalty will be deepened as well.

As an element of education, the educational space cannot be separated from the purpose of education. The place of education is not only the passage to deliver actual curriculum, but also the purpose itself that can be accomplished through educational content. That is because the purpose of education cannot be achieved only with instructors, students, curriculum, and methods, but requires a change in the perception of the educational space that represents the goal and the place where it all can be implemented. Nevertheless, the problem that lies with educational space is easy to be overlooked and it has been rather considered as an issue related to the finances or scale of the church. The church educational space gives birth to faith and growth, where spiritual development and experience may occur. However, the reality follows the drawbacks of conventional school classroom arrangements and structures. In addition, even if the church educational space can be arranged according to the needs of its students, it cannot deviate much from the standard uniform format. In particular, the basic environment of church educational space is similar to that of standard school system in terms of arrangement of furniture such as chairs, desks, and its physical structure. As the school system was originally designed and tailored for the purpose of delivering knowledge and standardization, the space for church education must stay away from it. Humans are born and die in a space, where encounter with God also happens. Also, communication with God causes spacial conversion to humans, changing the place of their visitation. So the church educational space must be more meticulously designed and comprehensive than that of school which pursues physical, educational, psychological, social, and artistic purposes because the church educational space pursues the liturgical elements, as well. Therefore, the Christian learning environmental arrangements must seek liturgical elements, which is the major Christian value, by placing Christian artwork or symbols for church visitors. So in this research, I want to stress the role of Christian educational space for spiritual growth and pursue intrinsic and extrinsic changes in learning environment, leading to a greater awareness of the Christian educational space.
