본 연구에서는 분동식 기준압력계의 기준분동(reference weight)의 부피를 측정하는 새로운 측정방법인 기체용적계(gas pycnometer) 측정방법을 제안하였다. 제안된 측정방법에 의한 측정결과로서 기준분동 1 kg, 2 kg, 5 kg에 대한 부피 측정불확도는 신뢰수준 95%에서 0.2%를 나타내었다. 기체용적계의 주요 장치는 샘플용기와 팽창용기, 정밀압력계, 정밀온도계, 진공펌프로 구성되며, 측정 원리는 일정한 용기 내에 들어 있는 일정한 양의 기체의 압력과 부피는 서로 반비례한다는 보일(boyle's law)의 법칙을 용용하였다. 본 결과는 현재까지 문헌이나 제조사로부터 기준분동 재질에 대한 밀도값을 적용하여 오던 것을 기준분동의 부피를 직접 측정하여 밀도값을 적용함으로서 압력기준기의 압력 기준값에 대한 국가측정표준의 신뢰도 향상에 기여될 것이다.

The American Law Institute(ALI) has presented drafts of "Principles of the law of software contracts" to clarify and unify the law of software transactions. These principles apply to agreements for the transfer of or access to software. Providing these principles means something in software contracts. First of all, these principles seek to limit the scope to cover only contracts involving software exchanged or accessed for consideration, while UCITA includes a wide variety of "computer information". Secondly, this project is "Principles" instead of "Restatement" which means that these principles are not the law unless a court adopts it. This is for flexibility not to hinder law's adoptability of new legal issues that might be created in the future since the software industry has developed. Third, the project seek to balance between software transferor's interest and transferees to permit the use of remote disablement in limited circumstances. These principles, however, should be considered some concerns in the future work. For example, not to be a unconscionable agreement, it is better to suggest the specific click-wrap procedure and be more illustrative about what types of browser-wrap language are acceptable and what types are not.

저작권법은 저작권 소유자의 권리와 이용자의 권리 간에 균형을 유지함으로써 지식정보에 대한 접근을 촉진하는 최선의 법적 도구이다. 이러한 측면에서 도서관을 위한 저작권의 제한 및 예외는 학습과 연구를 지원하고 정보의 흐름을 촉진하며, 대중에게 공정한 정보접근을 제공하고 지적 문화유산을 보존하는 데 중요하다. 이에 본 연구는 국내 저작권법의 도서관관련 권리제한조항을 축조분석하여 도서관 보관자료의 보존 및 제공용 복제, 도서관에서 인터넷 정보의 출력과 송신, 재생수단의 입수가 곤란한 자료 및 정부간행물의 보존용 복제와 제공, 장애인을 위한 도서관의 복제와 공중송신에 대한 개선방안을 제시하고 공정이용을 위한 일반규정의 도입방안을 제안하였다.

Five layers in mean flow are proposed by using the direct numerical simulation data of turbulent pipe flow up to Reτ = 3008. Viscous sublayer, buffer layer, mesolayer, log layer and core region are investigated. In the buffer layer, the viscous force is counterbalanced by the turbulent inertia from the streamwise mean momentum balance, and a log law occurs here. The overlap layer is composed of the mesolayer and the log layer. Above the buffer layer, the non-negligible viscous force causes the power law, and this region is the mesolayer, where it is the lower part of the overlap layer. At the upper part of the overlap layer, where the viscous force itself becomes naturally negligible, the log layer will appear due to that the acceleration force of the large-scale motions increases as the Reynolds number increases. In the core region, the velocity-defect form is satisfied with the power-law scaling.

An anti-dumping has become the trade policy of choice for developing countries as well as advanced countries, hence it is the impending issue to the export-oriented countries including Korea. After colligating the analysis on the trade and industrial policy between Korea and China as well as the analysis on the preceding research, the main reasons of anti-dumping were selected as followings; an unemployment rate, real GDP growth rate and consumer price increase as internal factors, and trade balance, regional coefficient and trade specification index as external factors. Then, the research on how the above seven variable factors can affect the number of anti-dumping measures was accomplished. For the empirical analysis, the above information was used after reorganizing them by on the quarterly basis. Through the use of the correlation analysis, backward elimination of multiple regression analysis model and time-series analysis, it has appeared that the unemployment rate appeared to be the most important factors of anti-dumping measures in addition to the increase rate of trade balance. The variable such as the unemployment rate is uncontrollable for us, so it is appropriate to establish and operate an preemptive monitoring system based on the increasing rate of the amount of export and increasing rate of trade surplus.

전산유체역학(CFD)을 이용하여 테일러 반응기 내 입자간 응집과 분해반응을 고려한 유동해석을 수행하였다. 입자크기분포를 파악하기 위하여 모멘트 적분법(QMOM)을 이용하여 집합체 균형방정식(Population Balance Equation)을 계산하였다. 초기 여섯 개의 모멘트를 이용하였으며, 응집커널은 Brownian kernel 과 turbulent kernel의 합을, 그리고 분해커널은 멱법칙 커널(power-law kernel)을 사용하였다. 입자의 초기 부피분율에 따른 최종 입자크기를 예측하였다. 그 결과, 초기 부피분율이 증가할수록 입자의 크기와 초기 성장속도가 증가하는 것을 확인하였다.

The purpose of this study is to examine the factors related to how Korean working mothers balance work and family. We used the first year data of 1661 working mothers participating Korean Longitudinal Study of Women and Families. When mothers were living with their parents-in-law, reported higher level of work-family spillover; whereas satisfaction with husband's household chores was more their related to lower level of work-family spillover. Attitudes placing lower priority on family, disagreement on their works with husband, and traditional family role perception were related to higher level of work-family interference. We also found that salary, working hours, job satisfaction, and a series of maternity protection programs, including maternity leave, were significantly related to work-family balance.

Logistics industry is being an important industry in Vietnam with the contribution from 8-10% of GDP recently. This industry employs about 15 millions people. Increasing the employees' job satisfaction is become one of the most concerns of managers in logistics companies to strengthen the employee engagement and improve their business performance. The aim of this study is to investigate how employees' perceptions of job satisfaction are influenced by factors such as job stress, leadership capability, work-life balance, and demographics. 426 workers in the logistics sector in Vietnam were surveyed online. The acquired data was analyzed using a structural equation model. In total 16 hypotheses were established, 13 of which were deemed to be significant. The results demonstrate how the literature-informed second-order constructs can potentially explain the overall job stress, leadership capability, and work-life balance of employees in the Vietnamese logistics industry. These variables account for 54.8% of job satisfaction. This study makes a theoretical contribution to the extant literature by showing how researching second-order constructs can improve the theory's capacity to predict employees' job satisfaction. The paper concludes with a set of recommendations for the management of logistics firms in Vietnam.

This empirical research aims to identify the relationship between fiscal and financial macroeconomic fundamentals and the volatility of government bonds' borrowing cost in an emerging country - Vietnam. The study covers the period from July 2006 to December 2019 and it is based on a sample of 1-year, 3-year, and 5-year government bonds, which represent short-term, medium-term and long-term sovereign bonds in Vietnam, respectively. The Generalized AutoRegressive Conditional Heteroskedasticity (GARCH) model and its derivatives such as EGARCH and TGARCH are applied on monthly dataset to examine and suggest a significant effect of fiscal and financial determinants of bond yield volatility. The findings of this study indicate that the variation of Vietnam government bond yields is in compliance with the theories of term structure of interest rate. The results also show that a proportion of the variation in the yields on Vietnam government bonds is attributed to the interest rate itself in the previous period, base rate, foreign interest rate, return of the stock market, fiscal deficit, public debt, and current account balance. Our results could be helpful in the macroeconomic policy formulation for policy-makers and in the investment practice for investors regarding the prediction of bond yield volatility.
