Even if Korea has established various legal guidelines as well as plans for the purpose of systematic management of urban citycapes, various problems have been pointed out, such as a decrease in operational efficiency because the legal framework is not clearly defined and the guidelines do not fully reflect regional characteristics. In the midst of this, Singapore is being mentioned as a representative example of enhancing international competitiveness by forming an outstanding urban cityscape through successful urban planning and operating system. Therefore, this study aims to suggest a direction for the improvement of Korea's urban planning and design guidelines by investigating and analyzing the characteristics of Singapore's urban planning system and design guidelines. As a result of the research and analysis, it was concluded that Singapore's urban planning system was based on the unified planning and management system. In particular, the Singapore Urban Design Guidelines provide differentiated guidelines to maintain and strengthen regional characteristics based on linkage with higher-level plans as detailed practical guidelines, and were operated as flexible guidelines reflecting the changes of the times and the needs of members of society. It also provides a direction for the improvement of the Korean urban design system, such as to increase the executionablity of the plan and the efficiency of operation by utilizing various guidance and support policies, rational and simplified deliberation procedures, and allow a platform that enhances the accessibility and convenience of related information.

Although rational genetic engineering is nowadays the favored method for microbial strain improvement, building up mutant libraries based on directed evolution for improvement is still in many cases the better option. In this regard, the demand for precise and efficient screening methods for mutants with high performance has stimulated the development of biosensor-based high-throughput screening strategies. Genetically encoded biosensors provide powerful tools to couple the desired phenotype to a detectable signal, such as fluorescence and growth rate. Herein, we review recent advances in engineering several classes of biosensors and their applications in directed evolution. Furthermore, we compare and discuss the screening advantages and limitations of two-component biosensors, transcription-factor-based biosensors, and RNA-based biosensors. Engineering these biosensors has focused mainly on modifying the expression level or structure of the biosensor components to optimize the dynamic range, specificity, and detection range. Finally, the applications of biosensors in the evolution of proteins, metabolic pathways, and genome-scale metabolic networks are described. This review provides potential guidance in the design of biosensors and their applications in improving the bioproduction of microbial cell factories through directed evolution.

The purpose of this study was to investigate the disposition of adolescents in their ornament wearing pattern associate with their life style and clothing behavior. The subject of this study consists of 345 middle and high school girls living in Chung-Nam Province and Taejon Metropolitan City. SPSS/PC+ program was utilized to calculated frequency(N), mean value(M) and standard deviation(SD) for statistical analysis. Differences among the populations were examined through f test, ANOVA. The results of this study reveals that the ornaments wearing patterns are significantly different according to their life style and clothing behavior as follows: 1. Correlation between the wear of ornaments and the life style: School girls who pursue the modernistic life style prefer the fashionable ornaments (e.g. sunglasses) and they are always in contact with the latest information. On the contrary, school girls who pursue the practical life style emphasize on the practical use when they purchase the ornaments, e.g. umbrella. School girls having romantic or passive nature have a preference for the brand name and brand image of the ornaments and they in general would like to buy ornaments such as the bracelets. 2. Correlation between the wear of ornaments and the clothing behavior: School girls having sympathetic nature and being deeply interested in clothing put a stress on the latest fashion of the ornaments. They usually want to buy fashionable ornaments such as the cellular phone, beeper and sunglasses. Subjects who estimate themselves by their garments are sensitive to the price of the ornaments while aesthetes emphasize the brand image of the ornaments. Chaste school girls put their emphasis on the quality of the ornaments and they most want to have functional hair bands. Following suggestions can be made based on the discussions above: It is necessary for us to have correct understanding about the correlation between the ornaments and clothing of school girls in order to lead them to have appropriate clothing behavior. Furthermore, it is required to construct a bridge linking a course of study to rational habits guidance which will provide us more appropriate tools for clothing behavior guidance.

This research was about analyzing students' major error types in the field of elementary 1st grade mathematics numbers and operations, and formulating and applying effective teaching methods to find out their effects. Among the errors the students were making, it was found that in the field of numbers there was more than 50% chance of making calculation mistakes in 50 rounds of rational counting. Also, in the field of operations, it was discovered that most of students' mistakes had to do with subtraction. The results from the classification of the 4 types of error showed that most errors were made from having inaccurate concept of knowledge and definition. Thus, it can be concluded that when elementary 1st grade teachers teach students mathematics, it is most important that they put best effort into firmly establishing the students fundamental concept, definition, facts, and functions. For that matter, students were interviewed one by one, and by implementing learning method using some concrete materials as tools, students were able to fix their own errors. More importantly, students were able to gain interest and become more willing to participate by joining in this program, which led to more effective guidance.

Objective: To analyze cost-effectiveness of morphine, MS contin and oxycodone in the treatment of cancer pain, providing guidance for rational drug use in the clinic. Methods: Confirmed by histology, a total of 171 patients with various cancers who required analgesic treatment were selected and divided into 3 groups, 57 cases for each group, given morphine, MS contin and oxycodone, respectively. If there appeared a poor short-term effect or aggravated sudden pain during the treatment, a short-acting morphine injection was given and adverse reactions were processed by symptomatic treatment. The pain relief rate and adverse reactions of groups were observed and pharmacoeconomics evaluation was undertaken. Results: The pain relief rates with morphine, MS contin and oxycodone were 89.5%(51/57), 91.2%(52/57) and 93.0%(53/57), respectively, with no difference samong groups (${\chi}^2=4.4489$, P=0.6162). The occurrence rates of adverse reactions were 59.7%(34/57), 54.4%(31/57) and 43.9%(25/57), again with no significant variation (P>0.05). The ratios of cost-effectiveness (C/E) for the 3 groups were $14.6{\pm}7.21$, $15.0{\pm}7.44$ and $16.1{\pm}8.10$. When the price of 3 kinds of analgesics was reduced by 10%, the ratios of cost-effectiveness were $12.2{\pm}6.53$, ($13.4{\pm}6.08$ and $14.5{\pm}6.74$ but there was no differences when compared with before the price adjustment (t=1.86, P=0.0651; t=1.30, P=0.1948; t=1.17, P=0.2453). Conclusion: Morphine, MS contin and oxycodone give similar pain relief and adverse reaction rates but of all, morphine is the preferred drug for the treatment of cancer pain from the perspective of pharmacoeconomics.

The solid oxide fuel cells (SOFCs) are the one of the most promising energy conversion devices which can directly convert chemical energy into electric power with high efficiency and low emission. The lowering operating temperature below 800 ℃ has been considered as the mostly considerable research and development for commercialization. The major issue is to maintain reasonably high performance of SOFCs at reduced temperatures due to increment of polarization resistance of electrodes and electrolyte. Thus, the alternative materials with high catalytic activities and fast oxygen ion conductivity are required. For recent advances in electrolyte materials and technology, newly designed, highly conductive electrolyte materials and structural engineering of them provide a new path for further reduction in ohmic polarization resistance from electrolytes. Here, a powerful strategy of the bilayer concept with various oxide electrolytes of SOFCs are briefly reviewed. These recent developments also highlight the need for electrolytes with greater conductivity to achieve a high performance, thus providing a useful guidance for the rational design of cell structures for SOFCs. Moreover, cell design, materials compatibility, processing methods, are discussed, along with their role in determining cell performance. Results from state-of-the-art SOFCs are presented, and future prospects are discussed.

This study explored the internal world through sandplay therapy for an elementary school boy who had social and emotional difficulties of poor peer relations, anxiety and withdrawal. This study examined the changing processes of sandboxes, how a boy expressed his internal world by the content themes in sandplay according to Turner (2009) based on analytical psychology and sandplay theories. There were 72 sessions. The initial phase was 1-6 (The beginning of war) expressing confusing wars as the start of a long internal journey. The intermediate phase was 7-55 (Struggle), dividing by phase I 7-18 (Hero's fight I), phase II 19-36 (Hero's fight II), phase III 37-48 (Seeking for a male identity), and phase IV 49-55 (Centering). The client identified himself as a teenaged hero and expressed the conflict between good and bad, between death and rebirth and struggled for seeking treasures in the fight of heroes. He found identity as a male by finding a sense of existence, establishing order in the middle of confusion, and expressing strong and rational masculinity. The final phase was 56-72 (The winner of the struggle). In the fights repeating, he expressed an adventurous and positive male energy such as racing, speed contests and a union in the opposites of hero and heroine as well as the birth of a new conscious. This study provides a basic knowledge of educational guidance in school and counseling fields by expanding the understanding of a boy's unconsciousness.

Objectives: South Korea's occupational safety and health legislation appears on the surface to have stronger regulations than any other country, but it is criticized for having many problems when viewed from the perspective of the effectiveness and universality of these regulations. Therefore, it is necessary to consider the validity of the regulatory content and the methods for contract work in South Korea. Methods: The main issues in contract work are compared and analyzed in terms of the occupational safety and health laws systems in South Korea and other developed countries. Based on this, problems related to contract regulation are derived from the perspective of legal policy studies. In addition, effective improvement measures for the derived problems will be proposed. Results: Other developed countries impose obligations suitable for the status and role of persons who entrust work in consideration of the fact that they do not directly manage risks and in terms of the effectiveness of industrial accident prevention. These countries generally impose obligations such as management of facilities and machinery, cooperation and coordination with subcontractors, cooperation and coordination obligations between subcontractors, and guidance obligations on a person who entrusts a work. Conclusions: It is difficult to achieve effectiveness in preventing accidents with based on unreasonable regulations that do not conform to safety principles or legal theory. Regulations on contract work need to be converted to rational cogent regulations based on science and rationality, not ideology and emotion. To this end, the legal system for contract work must have international universality.
