The Kind of Knowledge that makes Network Stronger
( Woojung Jang ) 서암순창장학회 2014 Journal of Marketing Thought Vol.1 No.3
It is a key ability that a network members manage a variety of knowledge to survive in the volatile environment to improve the competitiveness of the network. This paper examines how knowledge sharing influences on network solidarity. The purpose of this research is to find out which knowledge type is more useful for robust network. This study classified knowledge into explicit versus tacit and examines how these knowledge types influence network solidarity respectively and which knowledge has stronger effect on the network solidarity. The empirical test was conducted with workers in networks of Korean engineering firms. The result of this study shows that two types of knowledge place different influence on network solidarity. Explicit knowledge sharing has a positive relationship with network solidarity as tacit knowledge sharing does and but, tacit knowledge sharing helps the network solidarity more firmly.
The Present and Future of the Reformed Fixed Book Price Regulation
( Woojung Jang ),( Jonghak Chay ) 서암순창장학회 2015 Journal of Marketing Thought Vol.2 No.3
A year has passed since implementing the reformed fixed book price regulation. It is time to evaluate how the reformed regulation has affected the book and publishing industry in Korea. The Fixed Book Price (FBP) regulation was reformed in 2014 to improve the book and publishing structure where small and midsized book stores have been struggling. The main purpose of the reformation is to establish a sound book distribution which can help small and midsized book stores to survive and to provide books of good quality and diversity. The current positive evaluation of this reformed regulation can be summarized in a 6.2% decline for the average price of new books published 18 month prior, and an increase in operating profits of large bookstores. However, ratings about a more important issue - small and medium-sized bookstore can coexist or not - are undecided as of yet. Also consumer’s opinions on the reformed fixed book price regulation are not viewed in a positive way. Consumers are still very price - sensitive and are not willing to spend their money on books. Therefore a worry about a vicious circle has come up in the book - publishing industry. The solution to this problem can be as follows: The book - publishing industry needs to adopt a complete fixed book price regulation and a fixed supply rate to encourage mutual growth of grand book stores and small-midsized book stores. Moreover, it is important to convince consumers of the importance and benefits of a reformation fixed book price regulation.

Carry out analysis the cross member’s different mounting bracket base no FR (Front engine Rear drive) vehicle. Studying the structure of cross member different mount bracket, figure out the approach method of cross member’s fatigue and stiffness improvement before full car test. As design the cross member, take advantage of this study. Design will be more improved result.
딥페이크 합성물에 대한 국내외 입법동향과 형사법적 수용문제 - 딥페이크 포르노(Deepfake Pornography)를 중심으로 -
장우정 ( Jang Woojung ),김주찬 ( Kim Juchan ) 한국소년정책학회 2020 少年保護硏究 Vol.33 No.2
Even though the provision of punishment is newly established in terms of the “possession” of Deepfake porno, it is virtually impossible to arrest and punish those who possess Deepfake porno in advance. However, it is time to take countermeasures to legitimately punish a new crime that have not been committed before, such as ‘nth rooms’, which is very harmful. Next, for virtual child pornography with Deepfake, the vertifiability of reproduced composites with realism will have to be considered. Advances in technology make it difficult to distinguish between reality and something similar to reality, There is no confirmation that such imaginary images or composites reduce or stop sexual abuse against children. The legal interests to be protected from these Deepfake virtual child pornography should be perceived as ‘social legal interests’ beyond the scope of a child's personal legal interests, and appropriate legislation and judicial judgments accordingly should be followed. Finally, in measures, for advanced criminal such as AI technology, criminal policies should be sought in a way that the community can recognize the social burden of them and accept. There is no denying that the development of intelligent information technology is definitely an area of increasing competitiveness at the national level. But along with the development of technology, the risk of abuse of technology that it has is also a goal that criminal law must confront. Therefore, it is necessary to have a realistic attitude to establish a predictable level of the response system through public-private partnership and to develop a gradual step-by-step legislation plan within a long-term framework.
습식 DCT(Dual Clutch Transmission) 클러치 팩 내부에서의 체결 동작에 따른 변속기유 거동 연구
김우정(WooJung Kim),이상호(SangHo Lee),장시열(Siyoul Jang) 한국트라이볼로지학회 2017 한국윤활학회지(윤활학회지) Vol.33 No.3
This work studies the flow behaviors in the gap between the friction pad and separator in wet-clutch systems. The fluid volume of the lubricant is modeled using the entire system of wet-clutch pack of a dual clutch transmission that has larger outer radius of odd gear shifts and smaller inner radius of even gear shifts. Flow behaviors in the gap of the clutch pad are computed using the gear shift modes that consider the real relative velocities between the friction pad and separator. Flow behaviors in the gap of the disengaged clutch pad are mainly investigated for the wet-clutch system, whereas the engaged clutch pad is modeled with no fluid rate through the contacting surfaces. The developed hydrodynamic fluid pressures and velocity fields in the clutch pad gap are computed to obtain the relevant information for managing flow rates in wet-clutch packs under dual operating conditions during gear shifts. These hydrodynamic pressures and velocity fields are compared on the basis of each gear level and gap location, which is necessary to determine the effects of groove patterns on the friction pad. Shear stresses in the gap locations are also computed on the basis of the gear level for the inner and outer clutch pads. The computed results are compared and used for the design of cooling capacity against frictional heat generation in wet-clutch pack systems.
