Apartments, having advantages of providing high density in limited area, are now booming in these days in Korea. However, most of the apartments are monotonus and all alike in the siteplan. As a result, they we in lack of humanity for the Apartment residents. The subject of this study is analysis and development of the site planning and design trends in Apartment Complexes in the official sector. In order to suggest the new planning and Design method, the study has analyzed the Apartment complexes exemplary, that have built in recent 10 years in Seoul districts. As a results a environmentally friendly planning and design in Apartment complexes estates as a new paradigm for environmentally sound sustainable development. Apartment Unit Plans have few Flexibility and Variability in the inner space.

This paper presents the design of DC protection Relay for Light Rail Transit system, which is very beginning product in domestic. Protection Function characteristic, principle and I/O interface including interlock signal has been introduced. The protection algorithm and EMC characteristics have been certified by official organization and Type test report has been introduced. Up to date in domestic, the test procedure for DC Protection relay hasn't been established so the new method and test equipment based on IEC regulations are proposed. Finally the product will be proved based on field test.

The domestic professional engineer qualification system has been changed after the enactment of the law in 1963. However, the domestic professional engineers have been unaccepted and unrecognized internationally. In addition, the domestic professional engineer system is operated in accordance with the individual laws of each ministry, but the official qualification examination is conducted by the Human Resource Development Service of Korea. Thus, the domestic professional engineer system has many problems in system itself and operating. In this research, we compare the domestic qualification system with the systems of other foreign countries, and propose how to improve the qualification system. This study limits the scope to the qualification examination for P·E. We suggest 3 ways to improve the qaulification examination; (1) The structure of the qualifications, (2) The testing method, and (3) The unification of the qualification system and operation.

The article analyzes the regulations of current criminal law, which ensures the protection and protection of information relations, offers the optimal model of the system of norms of the Criminal Code of Ukraine, which establishes liability for violation of information. The subject of the article is protected information, which should include information or data, the procedure for access to and distribution of which, regardless of the method of submission, storage or organization, are subject to legal regulation in accordance with laws and regulations. For the purposes of criminal law, information as an object of criminal law protection should be classified on the following grounds: depending on the content: personal or family secrets; information constituting a state secret; data included in the official secret; information that constitutes a professional secret; information that constitutes a commercial, tax, banking secret, and, depending on the medium - documented and undocumented.

In the history of elementary school mathematics education in Korea, the period led by the Government-General of Joseon during the Japanese colonial period cannot be omitted. As a way to grasp the real state of elementary school mathematics education at that time, there is a method of analyzing elementary school mathematics textbooks published by the Government-General of Joseon. However, the actual state of the publication of them was not sufficiently known. For this reason, this study surveys the actual state of the publication of those textbooks. To this end, real information on textbooks owned currently by various institutions and information on the publication of those textbooks in the official gazette and documents of the Government-General of Joseon were checked and organized.

Trust is essential for tax compliance. Various tax management issues might diminish taxpayer trust. As a result, as a measure of transparency in the services of the Indonesia's Directorate General of Taxes (DGT), a method for filing various taxpayer complaints is necessary. Whistleblowing is a service given by the DGT that accepts taxpayer issues and complaints. It may be accessed on the DGT's official website. This strategy was intended to increase compliance by instilling trust among taxpayers. This study aims to show how whistleblowing affects tax compliance by utilizing trust as a mediating variable. The study relied on 400 questionnaires issued directly to East Java I DGT Region taxpayers. SEM-PLS with the Smart-PLS tool was utilized for data analysis. According to the study's findings, whistleblowing positively impacts tax compliance, and trust partially mediates the effect of whistleblowing on tax compliance. The outcomes of this study provide empirical proof for the Slippery Slope Framework's contention that building trust is an essential technique for increasing taxpayer compliance.

Background : A new extraction method-heated ultrasonic extraction was qualitatively and quantitatively analyzed for the extraction of major ginsenosides from ginseng extract; this new high-performance liquid chromatography (HPLC) method was compared with the official extraction method of Korean industrial standards and standard for health functional food. Methods and Results : Ginsenoside compounds were analyzed for 35 minutes by the new HPLC analysis method using a Halo$^{(R)}$ RP-Amide column. The new HPLC analysis method was validated by the measurement of intra-day and inter-day precision, accuracy, limit of detection (LOD), and limit of quantification (LOQ) of each ginsenoside. The correlation coefficients (r2) for the calibration curves of the ginsenoside compounds were over 0.9997 in terms of linearity. The heated ultrasonic extraction method using ultrasonication for 30 minutes at $50^{\circ}C$ yielded higher amount of ginsenosides than the extraction method of the Korean industrial standards owing to the enhancement of extraction efficiency. Conclusions : Compared to the other extraction methods, the heated ultrasonic extraction method yielded a higher amount of ginsenoside Rb1 than Rg1 index compounds for the quality evaluation of ginseng roots.

The study on the development of rapid analytical method of PCBs containing waste was performed by considering the extraction, column cleanup process, analytical condition and so on. In the established method, new sample clean-up procedure, new quantification peaks and temperature program were introduced. Method detection limit of the method was 0.5 mg/L, and the method could save the total run time to 2/3, therefore save the analysis cost, The new rapid analytical method of transformer oil was suggested to the waste official test method.

This paper aimed to evaluate the results of alternative acute toxicity test on 83 wastewater samples. Each sample was tested by traditional method (using laboratory cultured D. magna as a test organism) and alternative method (using Toxikit which can be purchased from a specialized company). The relationship between Lab. culture toxicity and Toxkits toxicity indicated good relation ($r^2=0.84$, p<0.01, n = 83). Number of samples which showed a small difference of lower than 0.5 between two test methods were 52 and they account for 63 percent of collected samples. In addition, these 52 samples had a lower average toxicity of TU 0.5 (Lab. culture method) and TU 0.45 (Toxkits method). Whereas samples which indicated big difference of test results between two methods, had a tendency to show higher toxicity. From these results, alternative toxicity test method could be applied to the official test method, if samples would have a lower toxicity less than TU 2. Also, Toxikit standard toxicant test results indicated $EC_{50}$ values between 0.93 and 1.68 mg/L and these results were considered as valid for quality control standard.
