Maintaining the permanence of a company in the current rapidly changing business environment is not an easy task. Rather, the lifespan of a company can be said to be gradually decreasing. As such, the author of this paper, which describes the current market environment, is the sales organization of a large company. While leading the company, I thought about how to overcome the rapidly changing market and create an organization that continues to grow. As a result, I succeeded in creating an organization that continued to grow over the past two years, and the main activity of this result was the use of sales computer. It was clear that it was an information sharing activity. This can be said to be a result of proving that a series of activities to create and share information is important for the sales organization of ICT companies to actively respond to the rapidly changing market environment. Therefore, this study attempted to examine the relationship between knowledge management and business performance in the sales field of ICT companies, which has not been covered so far. Knowledge management is a four-stage activity from a process perspective, divided into knowledge creation, knowledge storage, knowledge transfer, and knowledge utilization. did. As a result of the study, first, knowledge management activities, such as knowledge creation and knowledge storage, were found to have a significant impact on financial performance. Second, knowledge management activities such as knowledge creation, knowledge storage, knowledge transfer, and knowledge utilization were all found to have an impact on non-financial performance. In the end, this study confirmed that efforts to turn tacit knowledge into knowledge in order to respond to the ever-changing ICT market are ultimately an important factor in growing a company.

영농형 태양광 시스템은 노지 작물 경작과 동일한 토지 상부에 설치된 태양광 패널을 통한 발전을 동시에 하는 시스템이다. 지금까지 영농형 태양광은 에너지와 식량의 양자구도로만 집중되어있다. 영농환경 중 하나인 토양수분은 강우 또는 관개수로 증발 및 유출⋅침투로 손실된 수분을 공급받아 노지 작물 생산에 기여한다. 본 연구는 식량, 에너지와 함께 물의 개념을 포함하여 영농형 태양광 시설을 보고자 하였으며, 미기상 관측을 통해 봄 기간 동안 휴경논에서 영농형 태양광 시설 하부의 토양수분과 지온의 변화를 분석하였다. 영농형 태양광 하부는 패널로 인한 부분차광 조건으로 지면에 입사되는 광 에너지량이 감소하여 지온이 낮아질 뿐만 아니라 토양수분 손실이 적어 대조구인 노지에 비해 습윤한 조건을 보인다. 또한, 태양광 하부는 에너지 제한 환경이며, 상대적으로 지온이 높은 노지는 수분 제한 환경으로 설명된다. 노지와 태양광 하부의 상이한 토양수분 환경은 필연적으로 작물에 영향을 미칠 것이며, 농업 환경과 농촌 경제를 고려한 지속가능한 대처가 필요하겠다.

This paper presents the implementation of two-arm modulation (TAM) technique for the independent control of a two-induction motor drive fed by a five-leg inverter (FLI). A carrier-based space vector pulse width modulation technique for TAM is proposed to generate switching signals for FLI. Two independent three-phase space vector modulators are utilized to control two motors. The motor drive system applies two separate indirect field-oriented control methods. The stationary voltage outputs from the vector control are synthesized in the three-phase space vector modulator to generate switching signals for FLI. The performance of the independent control of the motors and the voltage utilization factor are likewise analyzed. Simulation and experimental results verify the effectiveness of the proposed method for the independent control of the two-motor drive system. The proposed technique is successfully validated by dSPACE DS1103 experimental work.

As mass media has come to intervene with politics in a more proactive way during modern times, the image of a politician has evolved into a more relevant factor compared with political content. This phenomenon is known as "image politics", and such externalized images as non-verbal cues have grown in importance, along with the numbers of female politicians. Thus image strategy has been instituted as a major research theme in the field of political marketing, especially for female politicians. In accordance with this theme, this study aims to approach fashion as part of image strategy of female politicians, in order to reemphasize political fashion as a valuable resource. The methodologies employed in this study are based on both the literature and positive research. Female politicians have long utilized fashion styles that are, or are assumed to be, the most appealing to their target base of support in a predominantly male-centered sector. In this sense, appropriate choices in the usage of apparel items, colors, hair styles, accessories, and others according to each situation and respective hierarchies are of the utmost importance. When attending official ceremonies and other related meetings, the strategic superiority afforded to a scientific approach based on thorough fashion research, compared with personal taste is imperative. The significance of this study lies within the recognition of the importance of fashion image, and how to utilize fashion for image strategy in practice, through the investigative synthesis and review of major preceding research.

The purpose of this study is to analyze the concept of 'Gradual Differentiation' in parametric design in terms of pure model logic and thus describe the distinctive feature from the previous design method. To meet the purpose, it explores external cases like gradual factor identified in natural phenomenon and artworks and define the inherent model principles into "Self-similarity', "Correlation', and 'Temporality' by examining these features in terms of algorithm. Meanwhile, it identified the principle of gradual model representation in parametric design within a single system called 'Attractor System' by applying these three concepts into specific methods of parametric design, and by interpreting the logical structure through the association among 'Attractor', 'Field', and 'Differentiation'. The creative utilization of parameter shows that gradual model process in parametric design does not mean a passive "conversion process" merely replacing natural parameter with algorithm; rather, it refers to an active "generating process" creating new meanings and value. By continuing this process of conceptual understanding and insight, creative perspective and practical ability to interpret parameter can be improved.

This paper discusses a new perspective in health approach and the effect of health life on health status, and suggests some points to be improved in the establishment of health policies hereafter. Today's health problems changed from the acute epidemic diseases caused by simple factor to the multifactorial chronic diseases. Therefore, the health approach tries the holistic health approach, that is, the integrative approach by the interdisciplinary cooperation. With the advent of holistic health and holistic medicine in 1970's, the behavioral medicine was born in 1977, which is the interdisciplinary field concerned with the development and integration of behavioral and biomedical science knowledge and techniques relevent to prevention, diagnosis and treatment. As a means to the reducement of the unnecessary medical utilization and medical expense, the medical self care and self-help movement is well under way in the countries of America, England, and Canada, in which lay persons are encouraged to actively function for themselves to prevent, detect and treat common illnesses and to promote positive health habits through the health activation programs such as The Course for Activated Patients and The Health Activated Person. This study shows that the individual health life gives great positive effect to his health status with the reducement of medical expense. These above facts suggest that the preventive health programs such as health education should be developed and strengthened instead of medical care-oriented health policy.

This study examined the characteristics of generative design methodology, and it selected and analyzed 11 sites that provide design development services using generative methodology, INPUT data were classified into design form factor based on the choices of each and the variable form associated with each participant's movement. In designing the algorithms, designers set the meth- od and range of participation according to the characteristics of the design, and linked them with design components. This provided the study with a discriminative design process. This resulted in a type with morphological characteristics and a type that emphasized epidermal formability. The generative design methodology has value as an alternative process in the field of fashion where the utilization of digital technology is becoming universal based on contingency and variability. The results of this study can be used as basic data for the study of personalized design through the extension of methodology of digital-based fashion design and generative methodology.

Currently, many high-rise buildings are built in Korea for land-efficient utilization and vista. In high-rise buildings this tall, the use of high-strength concrete is essential to reduce the cross-section of structure members and secure axial load. However, this high strength concrete is vulnerable to spalling by fire, due to the water vapor pressure caused by the very high temperature in fire. To prevent this, the main method used is to reinforce the concrete with fiber. However, there has been little research on the pumpability of fiber reinforced high strength concrete. For this reason, this study features a performance review based on the properties and pumpability of fiber reinforced high strength concrete. In addition, the parameter of rheology was measured by extracting mortar from the concrete, and friction factor was measured through a 400 m horizontal pipe pumping test using the fiber reinforced high strength concrete. The basic information on fiber reinforced high strength concrete that we obtain through the experiments and review will contribute to the field.
