In this note, we prove that an Artinian local ring is G-semisimple (resp., SG-semisimple, 2-SG-semisimple) if and only if its maximal ideal is G-projective (resp., SG-projective, 2-SG-projective). As a corollary, we obtain the global statement of the above. We also give some examples of local G-semisimple rings whose maximal ideals are n-generated for some positive integer n.

Zagier introduced the term "strange identity" to describe an asymptotic relation between a certain q-hypergeometric series and a partial theta function at roots of unity. We show that behind Zagier's strange identity lies a statement about Bailey pairs. Using the iterative machinery of Bailey pairs then leads to many families of multisum strange identities, including Hikami's generalization of Zagier's identity.

Fuzzy set theory has been extensively researched in various fields of engineering. In nuclear science, a significant influence of fuzzy sets can be noticed. However, applications of fuzzy set theory to nuclear engineering is novel. In this paper, we start with a basic statement of the decision-making process based on fuzzy set theory, and then apply it to nuclear science with some practical applications (a fuzzy decision making in an accidental release to the atmosphere as well as in a problem of land suitability classification). We believe that the use of fuzzy set theory in nuclear science has potential advantages.

This study was carried out to find the problems of assessment on terrestrial ecosystem part in environmental impact analysis(EIA) and to suggest the proper amelioration measures by analyzing 19 environmental impact statements(EIS) published during the period from 1991 to 1994. The results obtained from this study were as follows. Field survey for the investigation of fauna and flora in project areas should be conducted at least 3 times a year and name of investigator should be written on the EIS clearly. Increase or decrease in degree of green naturality and productivity cannot be an absolute criteria for expressing the amount of changes in ecosystem. Evaluation for the ecosystems and their composition in project area is more important than presenting merely the increase or decrease in degree of green naturality and productivity. Alleviation measures in 19 EISs analyzed in this study were summarized into 6 types: They are establishment of landscape plan, transplanting of useful trees preservation of big tree and protected species, restoration and preservation of existent vegetation, establishment of soil conservation measures and diminution of the impact on animal. However, they were somewhat insufficient because they wouldn't suggest the alleviation measures in detail. The more positive counter-proposals are needed to decrease the impact of the project on terrestrial ecosystem.

This paper focuses on analyzing Korean language learning effect through the STEAM class using a robot which is targeted on multicultural elementary school students. For the purpose of it, the degree of difficulty and interest of how students feel has been measured. By using the programing tool of Korean language entering base, they learn the programming commands like as variable, data type, branching statement, loop statement, etc in Korean, the effect of Korean learning has been measured. It has been examined two interviews at the beginning and the end of the second semester to measure the effect of Korean language learning. As a result of this research, It can be realized that multicultural children who have similar linguistic characteristics and cultural sphere understood Korean language easily when they take the Korean language class by utilizing a robot, and the class had an effect on the acquisition of Korean language for multicultural children.

Noise of automotive alternators can be classified into mechanical noise, aerodynamic noise and electro-magnetic noise. which is the same as for electric motors. Previous studies show that the elect ro-magnetic noise takes a maw peak at the rotating frequency multiplied by the number of stator slots. It has not been proved clearly so far, however, that the major peak is wholely due to the stator slots. On the contrary it is well known that noise of motors. which has a mechanism similar to the alternator except that the number of stator slots in automotive alternators is in gene\integer multiple of that of rotor segments, is closely related to the number of rotor slots. Therefore, the statement that only the stator slots is the source of the major peak in the noise spectrum of alternators is suspicious although not easy, to show theoretically, that the statement is incorrect. In this paper. effects of the stator slots on the noise in an automotive alternator are experimentally investigated by intentionally modifying the number of stator slots in such a way that the number of the states is not an integer multiples of the rotor slots. It is shown that both the stator slots are not so much influential as the rotor slots and claimed that the major peak in the noise spectrum of conventional alternators is due to superposition of a component caused by the stator and a higher harmonic component caused by the rotor

The first and the longest criminal indictment case of Korean medico-legal battle, so called BORAMAE Hospital Incident, was finally on its end by Korean Supreme Court's decision on June 24, 2004, after 7 years long legal dispute via Seoul District Court and Seoul Superior Appeal Court's decision. Boramae Hospital case was the first Korean legal case of Withdrawing Life-sustaining treatment of mechanical respirator on 58 years old Extradural Hematoma victim who was on Respirator under Coma after multi-organ failure postoperatively(APACHE II score: 34-39). Two physicians who have involved patient's care and had helped to make discharge the Near-death patient to home after repeated demand of patient's wife, due to economic reason, were sentenced as homicidal crime. This review article will discuss the following items with the review of US cases, Quinlan(1976), Nancy Cruzan(1990), Barber (1983), Helen Wanglie(1990), Baby K (1994) and Baby L cases, along with Official Statement of ATS and other Academic dignitaries of US and World.: [1] Details of Boramae Hospital incident, medical facts description and legal language of homicidal crime sentence. [2] The medical dispute about the legal misinterpretation of patient's clinical status, regarding the severity of the victim with multi-organs failure on Respirator under coma with least chance of recovery, less than 10% probability. [3] Case study of US, of similar situation. [4] Introduction of ATS official Statement on Withdrawing/ Withholding Life sustaining treatment. [5] Patient Autonomy as basic principle.

The purpose of this study was to examine the reliability of Q-sorting and to develope a typology of coping to stress in school-age children through the use of Q-methodology. For the study, Q-statements are selected from the literature and interviews of 30 Children, A total number 153 statement were collected and 31 Q-samples were finally selected. AP-sample of 76 was selected the elementary school children. Each of respondents were given 31 coping strategies questionnaire and set of 31 statements with cartoon on each of cards and sorted them according to the 9-point scale. The result of the C-sorting by each subject were coded and analyzed using the QUANAL PC and SPSS PC＋ program. As a result of the analysis, There were significant relationship between score each item of question naire and score of sorted statement. Therefore, school-age children was able to Q-sorting(forced normal distribution). Also, the four types of coping were named as follows : Type I (n=35) : To search for the dynamic behaviors Type II (n=12) : To search for the intellectual behaviors Type III (n=22) : To search for emotional-spiritual behaviors Type IV (n=7) : To search for the self-abuse behaviors Throught the study, the implication for teachers, parents and school nurses is that there is needed to guide and to support adaptive coping behaviors. Also, it is recommended that the application of Q-methodology for study of children's subjective concepts like stress and coping.

We put forward a scheme of the theory of analysis, and G. E. Moore's theory of analysis is reconstructed. As C. H. Langford pointed out, Moore's theory commits to the paradox of analysis which says that if a analysis is correct then it is not informative, and if it is informative it is not correct. For, according to his theory, analysing statement is necessarily true identity statement and have some information. Moorean responses which is given by Max Black, Raymond Bradley and Norman Swartz, and Wilfrid Sellars rely on the distinction between the information about concepts and linguistic entity. These approaches are deficient in dealing properly with the difference in concepts as analysandum and analysans. Also, non-Moorean resolutions asserted by Myers, King, Black, and Earl are examined.

Art theorists support art productions by, introducing them to the public, explaining their meanings, and playing a crucial part in the development of art. These tasks seem like their opus. Because the principles of art production and the artistic languages are quite different from the ordinaries, we need 'interpreters' who can mediate us and the artists. Art works need interpretation. And the interpretation includes not only the characteristics of the given art work, but the customs, history, and the unique qualities of the race that produced the art work. The former director of the Korean National Museum, Choi Soon-woo wrote on the characteristics of Korean art as those that stem from the poised, arbitrary, and non-elaborate state of mind. The statement of the former Director of the National Museum has its weight far greater than just a personal opinion. In fact, we encounter the same resonance of this statement over and over reproduced in the mass media. The problem lies on that it deals with not only a single art work, but the entire Korean art. And going further, this kind of remarks are already infused into every sector of our thought on art appreciation. In this paper, I argue for a re-reading of the characteristics of Korean beauty based on two reasons. First, the characteristic of art work is contemporary, thus we cannot define the characteristics of entire Korean art in a few words without the context of the period of its making. Second, Director Choi defined the characteristics that I pointed out above as 'natural' and 'nature-friendly.' Nature or being natural is not an usual word that defines the characteristics of art work, which stands for the opposite side of the nature in the binary opposition of nature/culture. To delve into these misunderstandings of Korean beauty in the popular notions of Korean art, I suggest the re-reading of three major articles on Korean art: Ryoo Jong-yeol's "Korean race and its art," Ko You-seup's reiteration of Ryoo's thesis called "Discourses in Korean Art History and Aesthetics," and Yoon Hee-soon's antithesis of Ryoo Jong-yeol titiled "Studies on Korean Art History."
