This study aims at providing exercisable basic data for the management of protection areas in China by investigating into their legal system such as current laws, regulations, other relevant laws and international treaties and the management system such as history, classification, organization, personnel, funds and main management work.. In People's Republic of China (1954), several laws have been enacted in succession, such as Environment Law (1989), Regulations of Natural Reserves (1994) and Land Management Methods of Natural Reserves (1995). The development process of China's natural reserves is divided into the following five phases. In the initial phase (1956-1965), about 20 natural reserves were established; in the lag phase (1966-1978), a part of the natural reserves was destroyed under the influence of the Great Cultural Revolution; in the development phase (1979-1998), a normative legal system began to appear after the reform and opening up; in the leap phase (1999-2006), the number of natural reserves increased dramatically; in the stable phase ( 2007-present), the protection and restoration of the ecological environment have been implemented, and the supervision and management have been strengthened. China has established natural reserves of national, provincial, municipal and county levels according to the relevant laws. According to the resource categories, natural reserves can be divided into natural ecosystem reserves, wildlife reserves and natural relic reserves. The Ministry of Forestry is in charge of 1,958 natural reserves which account for 74.2 % of the total natural reserves in China. In China, there are 1,384 natural reserves (52.4 %) for which management institutions have been set up. 1,702 natural reserves (64.47 %) are equipped with management staff, showing a higher ratio than the natural reserves which have set up management institutions.

Previous test results showed that the current ASTM(American Standard for Testing and Materials) grip adapter for GFRP(Glass Fiber Reinforced Polymer) rebar was not fully successful in developing the design tensile strength of GFRP rebars with reasonable accuracy. It is because the current ASTM grip adapter which is composed of a pair of rectangular metal blocks of which inner faces are grooved along the longitudinal direction does not take into account the various geometric characteristics of GFRP rebar such as surface treatment, shape of bar cross section as well as physical characteristics such as poisson effect, elastic modulus in the transverse direction and so on. The objective of this paper is to provide how to proportion the optimum diameter of inner groove in ASTM grip adapter to develop design tensile strength of GFRP rebar. The proportioning of inner groove in ASTM grip adapter is based on the force equilibrium of GFRP rebar between tensile capacity and minimum frictional resistance required along the grip adapter. The frictional resistance of grip adapter is calculated based on the compressive strain compatibility in radial direction induced by the difference between diameter of GFRP rebar and inner groove In ASTM grip. All testing procedures were made according to the CSA S806-02 recommendations. From the preliminary test results on round-type GFRP rebars, it was found that maximum tensile loads acquired under the same testing conditions is highly affected by the diameter of inner groove in ASTM grip adapter. The grip adapter with specific dimension proportioned by proposed method recorded the highest tensile strength among them.

The purpose of this study was to examine how the contents and pedagogical styles of Food and Nutrition in the middle school home economics textbooks could promote constructivist learning. For this, Food and Nutrition contents of 12 current textbooks were analyzed, based upon the learning factors derived from both a practical problem-focused curriculum from the constructivist perspective, and the current home economics curriculum from the objectivist perspective. Pedagogical styles of the texts and exercises were classified into four types- neutral informative, injunctive, persuasive, and participative, out of which 'persuasive' and 'participative', in particular reflect the constructivist perspective. The major findings were as follows: First, the analysis results of Food and Nutrition contents showed that of 14 learning factors, 13 of the textbooks corresponded well to the current curriculum(92.9%). On the other hand, Out of the 26 learning factors, 18 of the textbooks corresponded to the practical problem-focused curriculum(72.4%). Classified into each stage of the practical problem solving processes, only learning factors related with 'the concepts of the valued ends' were fully covered. However, the other learning factors related with the concepts of 'the practical problem', 'the context', 'the action' and 'the consequence', that is the factors particularly related with 'the concepts of the context', were not properly addressed. Besides, learning factors were not addressed from diverse viewpoints, especially from the social perspective. Second, the analysis of pedagogical style related to Food and Nutrition illustrated that the neutral informative(59.9%) in texts, and the participative in exercises(60.4%), were most common. However, persuasive and participative were insufficient in texts(22.1%). Furthermore even though the exercises, are more likely to be described from the constructivist perspective, nearly none of the exercises was considered from the social perspective. In conclusion, this study showed that Food and Nutrition in Korean home economics textbooks need to reflect constructivist learning better.

This study attempted to analyze the contents of Practical Arts(Technology Home Economics)Textbooks written by the 7th national curriculum in a gender equity education. The objective of this study was to suggest some improvements which should be solved in terms of gender equity in Practical Arts, Technology and Home Economics education through analyzing their teaching and learning contents. Quantitative analysis were carried out for the objective of this study, Practical Arts(Technology Home Economics)Textbooks were divided into Technology and Home Economics fields. The pictures and illustration were analyzed in terms of sexual discrimination considering the social status and role. The analysis results were as follows. First, there were few cases of sexual discrimination in the texts. On the other hand, there were some cases of sexual discrimination in the pictures and illustration. Considering the results of some studies carried out in the 6th national curriculum, many problems raised in a gender equity education standpoint in the studies were solved. However, there were some cases of sexual discrimination which should be improved in the textbooks written by the 7th national curriculum. Second, there were few cases of sexual discrimination in Practical Arts textbooks. On the contrary many problems in terms of gender equity education were found in the textbooks of Technology and Home Economics. This result may be caused by the characteristics of Technology and Home Economics. The traditional viewpoint toward Technology and Home economics Textbook needs to be changed. In other words, their textbooks have to include practical contents for the positive sense of value and right sexual roles in terms of gender equity education. The contents of Practical Arts(Technology Home economics)Textbooks should be designed considering the articulation among the subjects and grades especially in terms of gender equity education.

This study was conducted to provide basic data for a transparent and fair bidding system by identifying problems and suggesting improvement measures through an analysis of the bidding status for construction projects and service-related landscaping of multi-family housing. To this end, we used the data from the "Multi-Family Housing Management Information System (K-apt)" that provides the history of apartment maintenance, bidding information, and the electronic bidding system to examine the winning bid status and amount, along with the size and trends of the winning bids by year, and the results of the selection of operators by construction type. As a result, it was found that out of the total number of successful bids (36,831), 4.4% (16,631) were in the landscaping business, and the average winning bid value was found to be about 24 million won. According to the data, 73% of the landscaping cases were valued between 3 million won and 30 million won, and 58.6% of the cases were in the field of "pest prevention and maintenance". 36% of the total number of bids were awarded from February to April, with "general competitive bidding" accounting for 59.8% of the bidding methods. As for the method of selecting the winning bidder, 55% adopted the "lowest bid" and "electronic bidding method," and 45% adopted the "qualification screening system" and "direct bidding method." As an improvement to the problems derived from the bidding status data, the following are recommended: First, the exception clause to the current 'electronic bidding method' application regulations must be minimized to activate the electronic bidding method so that a fair bidding system can be operated. Second, landscaping management standards for green area environmental quality of multi-family housing must be prepared. Third, the provisions for preparing design books, such as detailed statements and drawings before the bidding announcement, and calculating the basic amount shall be prepared so that fair bidding can be made by specifying the details of the project concretely and objectively must be made. Fourth, for various bidding conditions in the 'business operator selection guidelines', detailed guidelines for each condition, not the selection, need to be prepared to maintain fairness and consistency. These measures are believed to beuseful in the fair selection of landscaping operators for multi-family housing projects and to prepare objective and reasonable standards for the maintenance of landscaping facilities and a green environment.

생물학적 동등성 시험은 동일 성분을 동량 함유한 제제가 유사조건에서 투여되었을 경우 그 유효성분이 전신순환혈이나 작용부위에서 유용하게 되는 속도 및 양에 큰 차이가 없음을 입증하는 시험이다. 즉 이미 제조허가 되어 시판중인 의약품과 동일한 품목의 제조허가를 받기 위한 경우이거나 생체이용률이 동일함을 증명하기 위해 실시하는 시험이다. 우리 나라에서는 1989년 1월 1일 이후 허가된 전문의약품으로서 신약과 동일한 의약품, 패취제제, 제제개선을 통해 흡수율을 높이는 경우에 생물학적 동등성 시험을 하도록 의무화하고 있다. 미국 FDA는 1975년 6월 생체이용률, 생물학적 동등성에 관한 규제안을 발표하였고, 우리 나라에서도 1988년 10월에 생물학적 동등성 시험 기준을 제정하였다. 유럽에서는 1991년 12월 CPMP(Committee for Proprietary Medicinal Products)에 의해 최초로 "생체이용률 및 생물학적 동등성에 대한 가이드라인"이 채택되었다. 그후 전문가 회의를 거쳐 규정 전반에 관한 것과 일반적 항목에 대한 검토가 이루어져 최종 개정된 가이드라인이 만들어졌다. 현재 in vivo 생체 이용률을 비교하는 생물학적 동등성 시험의 중요성이 증대되고 있고, 국제적으로도 각 국가별 생물학적 동등성 시험의 평가방법이나 기준설정에 대한 연구가 다양하게 이루어지고 있다. 또한 ICH에서도 생물학적 동등성 시험의 국제적 조화를 위한 시도가 이루어지고 있다. 우리 나라의 현행 생물학적 동등성 기준은 1998년 개정된 것을 사용하고 있으나 국제적 발전 추세에 맞추어 기준의 제고를 모색하고 있다. 그 일환으로 유럽의 "의약품의 생체이용률 및 생물학적 동등성 시험 가이드라인"을 소개하고자 한다., globunlin II의 두 component로 분리(分離)되었고 oryzenin은 시료(試料) 육우(陸羽) 132호(號), 등판(藤坂) 5호(號), 관산(關山) 재건(再建)에서는 oryzenin I, oryzenin II, oryzenin III의 3 component를 분리(分離)하였고 팔달(八達), 진흥(振興), 서광(瑞光), 은방주(銀坊主), 다마금(多摩錦), Pin Galw56의 6시료(試料)에서는 oryzenin II, oryzenin III의 2 component만 분리(分離)하였다. 3. 각(各) fraction을 여지전기영동(濾紙電氣泳動)하여 각(各) component의 농도곡선(濃度曲線)에 의해 함량(含量)을 구(求)한 결과(結果) albumin 0.26%, globulin I, 0.35%, globulin II, 0.32%, prolamin, 0.41%, oryzenin I, 0.30%, oryzenin II, 2.23%, oryzenin III, 2.66%이었다.미국의 경우 3일 이내 전화나 FAX로 보고하고, 10일이내 문서로써 보고하도록 되어 있다. 이러한 임상적 안전성 자료 관리에 대한 신속 보고 정의 및 기준에 대해서는 ICH에서도 논의가 되어 Step 4까지 다다르고 있으므로 앞으로 각 국에서의 적용만 남아있는 상태이고 보면 신약의 개발과 더불어 임상시험에서의 부작용등의 안전성 자료 관리에 대한 중요성은 더욱 강조될 것이다.공하는 음식의 섭취정도에도 영향을 주고 있으므로 학생들에게 학부모와 전담교사 및 학교영양사는 학생들에게 이상적인 아침식사에 대한 교육은 물론이고 아침식사를 실천할 수 있도록 다양한 방안에 대해 함께 연구해야 하겠다. 정부차원에서 학교급식에 아침식사 프로그램을 도입할

The objectives of this study were to evaluate the sensory characteristic quality of commercial milk brands selling in the market under the preservation at the temperature of $7^{\circ}C$ and $10^{\circ}C$ stored during the period of shelf-life. Quantitative descriptive analysis after developing of descriptive terms and cluster characterization by PCA analysis over a total of 128 LTLT, HTST, UHT and UHT-ESL milks, were conducted by 8 trained panelists. A total of fourteen attributes; three aroma attributes (grassy, milky, cultured milk aroma) and seven flavor/taste attributes (sweet, salty, sour, milk, cooked, cheesy, paper board) and one aftertaste attributes (rancid flavor) and one texture attributes (viscous), were developed as descriptive terms. Significant differences (P<0.01) in the sensory attributes; sweet, milky, cheesy etc. in UHT milk and sour, cheesy, paper board, rancid etc. in UHT-ESL milk were also found between the two different temperatures within the shelf life, but both type of pasteurized milk samples (LTLT and HTST) showed significant differences (P<0.01) in the attributes, such as cultured milk aroma, salty, sour, cheesy, rancid in LTLT milk and grassy, milky, salty in HTST milk and difference (P<0.05) in cultured milk aroma for HTST milk. Therefore, from the viewpoint of not only hygienic quality but also sensory characteristics, it is required for the better acceptance of milk consumers to amendment on the regulation in relation to the preservation standard of pasteurized milk as well as UHT milk to lower than $7^{\circ}C$.

The executive authority of the Ministry of Public Administration and Security on the 'management of security of the government complexes' is not sufficiently secured only with the organization law, the Government Organization Act. It is needed to establish an administrative actions law, an individual law that sets detailed contents and limitations of the executive authority to be stipulated. The current regulation, Regulation on the Management of the Government Complexes which is a Presidential Decree, is a legal decree that lacks a legal basis. The decree does not match with the current constitutional framework and raises the issue of its legality. The regulation may have the characteristics as a public property management law so far as it stipulates such matters as supply and maintenance management for the complexes, acquisition and disposition of complexes, facilities management of complexes, etc. However, the regulation includes high authority actions by an administrative organization, such as facilities security and order maintenance including restriction and control of access. This makes the regulation have the characteristics of a public property policy act as well. To supplement the legal framework for this situation, it is needed to level up some of the provisions relating to protection and security management to the level of an act as they stipulate high authority actions by an administrative organization. Other matters in the Regulation on the Management of the Government Complexes such as provisions relating to supply and allocation of complexes, etc. may be maintained as they are. In addition, the protection officers (general service official) does not own legal authority and have limitations on securing the capability to deal with the situations on implementing the on-site protection duty. Therefore, it is needed for the protection officers to secure protection duty-related authority by stipulating in a law. The main contents of the law on the protection and security of the government complexes may be those matters providing reservations on the implementations of laws. These may include the limitation of rights of and charging obligations on the people such as restricting the actions of personnel in the complex, rights and obligations of protection personnels relating to their duties, use of weapons, training of protection personnel, penal provisions, etc. These legal reservations should be included in an individual act.

The applicability of photostimulated-luminescence (PSL) and thermoluminescence (TL) for the detection of 12 food materials (potato, onion, garlic, dried pumpkin, black mushroom, black soybean, Cheongkukjang powder, sea mustard, pepper powder, Ramyun soup, corn tea, and green tea powder) irradiated with an electron beam, gamma ray, and X ray at a range of 0.15 to 10 kGy was investigated. For PSL, negative results (less than 700 photon counts (PCs)) were observed from non-irradiated foods while the irradiated foods showed intermediate (879 to 2,414 PCs) and/or positive (19,951 to 65,919,035 PCs) values. In all irradiated samples, the maximum peak of the TL glow curve was observed between 150 and $250^{\circ}C$. Our findings demonstrate the successful application of PSL and TL to determine whether food items were irradiated or not. However, there were no significant differences among the radiation sources.

The purpose of our study was to investigate the migration level of lead (Pb), cadmium (Cd), antimony (Sb), arsenic (As), hexavalent chromium ($Cr^{6+}$) and mercury (Hg) from cookwares into food simulants and to evaluate the safety of each heavy metals. The test articles for heavy metals were glassware, ceramics, enamel, earthenware, polypropylene and polyethylene cookwares for Pb and Cd, enamel for Sb, earthenware for As, polyethylene and polypropylene cookwares for $Cr^{6+}$ and Hg. All the article samples of 391 intended for contact with foods were purchased in domestic markets. Pb, Cd, Sb and As were analyzed by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), $Cr^{6+}$ by UV visible spectrophotometer and Hg by mercury analyzer. The migration levels of heavy metals in all the samples were within the migration limits of Ministry of Food and Drug Safety (MFDS). As a result of safety evaluation, our results showed that the estimated daily intakes (EDI, mg/kg bw/day) were $9.12{\times}10^{-6}$ and $8.83{\times}10^{-7}$ for Pb and Cd from ceramics and $1.19{\times}10^{-5}$, $1.23{\times}10^{-5}$ and $7.52{\times}10^{-6}$ for Pb, Cd and Sb from enamel. Tolerable daily intakes (TDI, mg/kg bw/day) were established respectively as 0.0036, 0.00081, 0.0021, and 0.0006 for Pb, Cd, As and Hg by JECFA (Joint FAO/WHO Expert Committee on Food Additives), as 0.0060 for Sb by WHO (World Health Organization). When comparing with TDIs, the EDIs accounted for 0.25% and 0.11% for Pb and Cd from ceramics and 0.33%, 1.52% and 0.13% for Pb, Cd and Sb from enamel.
