Composting is very important in practicing environmentally sustainable agriculture because compost application conserve soil and its fertility. Composting is also another important factor in achieving high national recycling goal above 20%. To encourage composting, it is necessary to revise current regulations on composting. Current regulation set the limit only for 4 metals and the limit is significantly strict, especially for lead, which dictates less than 150ppm. In this paper, authors suggested reasonable standard for some heavy metal concentration in compost taking into account other country's criteria.

고온성이며 호알칼리성인 Bacillus sp. TA-11이 생성하는 Invertase의 생합성 조절 기작을 규명하고자 먼저 이들의 유도와 억제에 관하여 검토하였다. Invertase는 10mM sucrose을 함유한 생합성 조절배지에서 3시간에 효율적으로 유도되었고 glucose는 sucrose에 의한 invertase 유도를 inducer exclusion 방식으로 억제시켰다. CAMP의 첨가로 glucose에 의한 catabolic repression이 다소 줄어들었다.

The regulations for costume were set to improve people's moral fiber and cultural standards. In the 17th and 18th century, the main aim of this regulation was to prohibit luxury. But being the turning point to a modem state, with breaking social status and development of commerce, industry, and the mind of imitation, regulation for luxury wasn't enforced, but rather it brought many revolutionary changes in costume. Restraining human impulse to express beauty was no longer subject to regulation. Therefore, people started to recognize the human figure with shorter Jegory(저고리) and strengthened ceremonial capacity by broadening po's(포) sleeves. The silk fabrics were the most popular fabric during this era, special patterns were added for decoration and also for blessings. Complementary colors were used for contrast on the collar (깃), cuffs (끝동), Gyotrnagi (곁마기), and sash (고름). This color composition gave a younger and more active look. And with red stripes on the sleeves, it emphasized the beauty of the color arrangements as well as providing protection from the devil.

Concerning the regulation of Internet service and the control of electronic commerce in China, It has not specific regulation and various rules or measures to enforce it yet. The common regulatory measures are that online business in some special areas must acquire a license or approval from relative agencies in advance. But whether licensing is an effect regulatory measure still takes time to verify. Accordingly these measures must be unified or coordinated to be enforced effectively. In order to encourage the development of E-Commerce, China will need to focus on developing rules that take advantage of the internet to encourage the economy, and establishing new legal rules or amending the traditional law to create a safe and secure legal environment for online transactions.

The purpose of this study is to examine the tendency of certified organic cosmetics market and the certification standards and regulations they are under, compare one of the most commonly used COSMOS-standard AISBL with the Korea Ministry of Food and Drug Safety (MFDS) organic cosmetic standard regulation. And then examining their differences and any potential issues is to present suggestions to be made as data for certification standard for natural & organic cosmetics in Korea regulation. This contents of study will be used as good research and development to promote the sustainable growth of the natural & organic cosmetic ingredients which have been grown by organic farmers certified. Also certified organic ingredients may help to growth the organic industry. I believe these are actual comparative for application to develop of natural and organic cosmetics in Korea as well the strengthening of the competitiveness of organic cosmetics certified in the world.

A comparative study on the prevention regulation of historical heritage between Korea and Japan. Every years fire accident to historical building is increasing such as Daewoongjun, Naksansa, Namdaemun and so on. The aim of this comparative study is to investigate and compare the prevention regulation in the side of fire safety of historical building between Korea and Japan. This study focus on the background of development and exchange of Fire safety law in Japan because of same condition, building material and prevention regulation.

This paper presents a new switch-control approach for multiphase interleaved converters. Development of the proposed technique is based on control-signal generation for multi-unit synchronization. Current sharing among the switching cells and voltage regulation are achieved by means of a multi-loop control scheme regardless of changes in input voltage and load. System stability is ensured by single-pole compensation. This proposed technique is straightforward, reliable and inexpensive, and can be applied to any higher number of cells without difficulty.

In this paper, a new development in the time optimal control theory in sliding mode control systems for multi-quadrant buck converters with a variable load is presented. In general, the closed-loop time optimal control system is applied to multi-quadrant buck converters for output regulation, so that an optimal switching surface is obtained. Moreover, an adjusted optimal sliding mode controller is suggested which adjusts the controller parameters to give an optimal switching surface. In addition, a description of the transient response of the closed-loop system is proposed and used to damp any output or input disturbances in minimum time. Numerical simulations and experimental results are employed to demonstrate that the output regulation time and transient performances of dc/dc converters using the proposed technique are improved effectively when compared to the classical sliding mode control method.

Purpose: Recently, the government of China has established new safety regulations for towing devices. The new Chinese regulation has more unfavorable conditions than the conditions of other countries. So the various measures have been reviewed to satisfy this regulation. Methods: The regulation conditions were compared through analysis of strain energy, and a method for improving the accuracy of analysis is suggested. In addition, the test method considering the tolerance is presented through tolerance analysis. This paper also explained importance of confirming the quality of products through a case of poor quality of Chinese products such as poor heat treatment. Result: We could know how strong Chinese regulations are stronger than other national laws and investigated which member receives a lot of strain energy. In order to cope with these Chinese regulations, we suggested improvement of analysis accuracy, test method through tolerance analysis, and heat treatment quality. Conclusion: This paper contributed to general counterplan of the strengthened new Chinese regulations for towing device.

The small ubiquitin-related modification molecule (SUMO), one of the post-translational modification molecules, is involved in a variety of cellular functions where it regulates protein activity and stability, transcription, and cell cycling. Modulation of protein SUMOylation or deSUMOylation modification has been associated with regulation of carcinogenesis in breast cancer. In the dynamic processes of SUMOylation and deSUMOylation in a variety of cancers, SUMO proteases (SENPs), reverse SUMOylation by isopeptidase activity and SENPs are mostly elevated, and are related to poor patient prognosis. Although underlying mechanisms have been suggested for how SENPs participate in breast cancer tumorigenesis, such as through regulation of target protein transactivation, cancer cell survival, cell cycle, or other post-translational modification-related machinery recruitment, the effect of SENP isoform-specific inhibitors on the progression of breast cancer have not been well evaluated. This review will introduce the functions of SENP1 and SENP2 and the underlying signaling pathways in breast cancer for use in discovery of new biomarkers for diagnosis or therapeutic targets for treatment.
