The purpose of this study was to examine the effects of treadmill walking speed and elastic chest band (ECB) on respiratory function in healthy young women with limited chest mobility. Twenty women with limited chest mobility were volunteered for this study. The speed of treadmill walking was determined as 3.0 km/hr and 5.5 km/hr. The ECB was set at the level between 8 and 12 ribs. A 10-min treadmill walking at each walking speed was performed with the ECB. Respiratory function was evaluated by forced vital capacity(FVC), forced expiratory volume in one second (FEV1), forced expiratory volume in one second/forced vital capacity (FEV1/FVC), peak expiratory flow(PEF), expiratory reserve volume, vital capacity, inspiratory reserve volume(IRV), Maximum voluntary ventilation(MVV). Measurements were carried out the baseline and after a 3.0 km/hr and 5.5 km/hr of treadmill walking speed. With the ECB, there was statistically significantly different for the FEV1/FVC in the treadmill walking speed of 3.0 km/hr and the PEF in the 5.5 km/hr when comparing those of the baseline (p<.05). In addition, in the treadmill walking speed of 5.5 km/hr, significant differences were found for FVC and MVV between the baseline and no ECB (p<.05). All parameters were significantly different between the baseline and treadmill walking speed of 5.5 km/hr, except values of FEV1/FVC and IRV (p<.05). These findings suggest that treadmill walking speed of 5.5 km/hr is probably more favorable to improve pulmonary function of females with limited chest mobility than the 3.0 km/hr, with incorporating of the ECB. Further studies need to evidence the generality of our results.

Climate change is believed to increase the amount of dissolved organic matter in surface water, as a result of the release of bulk organic matter, which make difficult to achieve a high quality of drinking water via conventional water treatment techniques. Therefore, the natural water treatment techniques, such as managed aquifer recharge (MAR), can be proposed as a alternative method to improve water quality greatly. Removal of bulk organic matter using managed aquifer recharge system is mainly achieved by biodegradation. Biodegradable dissolved organic carbon (BDOC) and assimilable organic carbon (AOC) can be used as water quality indicators for biological stability of drinking water. In this study, we compared the change of BDOC and AOC with respect to pretreatment methods (i.e., ozone or peroxone). The oxidative pretreatment can transform the recalcitrant organic matter into readily biodegradable one (i.e., BDOC and AOC). We also investigated the differences of organic matter characteristics between BDOC and AOC. We observed the decreases in dissolved organic carbon (DOC) and the tryptophan-like fluorescence intensities. Liquid chromatographic - organic carbon detection (LC-OCD) analysis also showed the reduction of the low molecular weight (LMW) fraction (15% removed, less than 500 Da), which is known to be easily biodegradable, and the biopolymers, high molecular weight fractions (66%). Therefore, BDOC consists of a broad range of organic matter characteristics with respect to molecular weight. In AOC, low molecular weight organic matter and biopolymers fraction was reduced by 11 and 6%, respectively. It confirmed that biodegradation by microorganisms as the main removal mechanism in AOC, while BDOC has biodegradation by microorganism as well as the sorption effects from the sand. O3 and O3 + H2O2 were compared with respect to biological stability and dissolved organic matter characteristics. BDOC and AOC were determined to be about 1.9 times for O3 and about 1.4 times for O3 + H2O2. It was confirmed that O3 enhanced the biodegradability by increasing LMW dissolved organic matter.

한일국제결혼가정 청소년의 계승어 사용에 관한 개별성 연구

In this study, differences in the use of Japanese as a heritage language between the adolescents of Korean-Japanese international marriage families were analyzed. The data obtained from five interviewees were qualitatively analyzed. The analysis focused on difficulties in acquiring Japanese as a heritage language, environments and people's attitudes in relation to the language, distances felt for Korean and Japanese people (societies), and the recognition of identity. The types of individuality were classified by analyzing the relationships among the concepts that were derived using the modified grounded theory. Considering bilingual and monolingual speakers as main phenomena, “the meaningful use of heritage language in families”, “contact with Japanese popular culture”, and “repeated experiences with the Japanese society” could be classified as causal conditions. “Chinese characters as obstacles” and “being left as homework”, which appeared to be widely involved in the phenomena of bilingual and monolingual speakers while being affected by the motivation, attitude of the interviewees, could be classified as contextual conditions. In addition, “the Japanese language as a practical second language” and “the Japanese language as a target of attack”, which describe the meaning of the Japanese language in Korean society, could be classified as intervention conditions. The concepts of “familiar reality”, “unknown country with possibilities”, “natural Korean identity”, “anxiety felt as a Japanese”, “forced identity”, and “selected identity” were classified as elements that describe the emotions of the interviewees for the two countries. Finally, the concepts of “confused identity”, “balanced dual identity”, “thinking from the perspective of Korean people”, and “covering the causes of conflict” could be classified as consequences and countermeasures. 본고는 한일국제결혼가정 청소년들의 계승일본어 사용과 관련된 다양한 개별성을 분석한 연구로, 5명의 인터뷰 참가자들로부터 얻은 데이터를 질적으로 분석하였다. 분석 테마는 계승일본어 습득의 요인과 곤란, 계승어와 관련된 환경과 주변인들의 태도, 한국인(사회)과 일본인(사회)에 대해서 느끼는 거리감, 그리고 정체성 인식에 관한 것이었다. 수정판 근거이론의 방법으로 도출된 개념들의 관계를 분석하였다. 그 결과 이중언어화자나 단일언어화자를 중심 현상으로 봤을 때 「가정 내의 의미 있는 계승어 사용」, 「일본 대중문화와의 접촉」, 「반복적인 일본사회 경험」을 인과적 조건으로 분류하였고, 인터뷰 참여자 고유의 동기나 태도의 영향을 받으면서 이중언어화자나 단일언어화자라는 현상에 광범위하게 관여하는 것으로 보였던 「한자의 벽에 부딪힘」과 「숙제로 남겨짐」을 맥락적 조건으로 분류할 수 있었다. 그리고 한국 사회에서 일본어가 갖고 있는 의미를 설명해 주는 「실용적인 제2외국어로서의 일본어」와 「공격의 대상으로서의 일본어」는 중재적 조건으로, 「익숙한 현실세계」, 「가능성과 미지의 나라」, 「마땅한 한국인」, 「일본인으로 느끼는 위축감」, 「강요받는 정체성」, 「선택하는 정체성」 개념은 인터뷰 참가자들이 갖고 있는 양국에 대한 정서를 설명해 주는 것으로 분류하였다. 그리고 「정체성 혼란」, 「균형잡힌 이중 정체성」, 「한국인의 시각으로 바라보기」, 「갈등의 씨앗 덮어버리기」 개념은 결과 및 대처로 분류할 수 있었다.

박세희,齊藤明美 한국일어교육학회 2020 일본어교육연구 Vol.0 No.50

This study deals with the motivation and image of learning the Japanese language in South Korea. According to the results of a questionnaire survey of South Korean university students conducted in 2017, the top five motivations of studying Japanese language were as follows: No.1 Interest in Japan, Japanese people and culture, No.2 Wish to know about Japan, No.3 Going to Japan, No.4 Interest in Japanese manga and animation, No.5 Interest in Japanese movies and television programs. This shows that learners of Japanese in South Korea are interested in Japan and its people, manga, animation, movies and television programs. A survey was conducted also in 2017 on South Korean university students studying Japanese language as their major, students studying it as a general education subject, and students who previously studied but are no longer studying it (non learners), in order to examine the images that students have of Japan, its people and the language, and the factors that influence the formation of those images. Survey results show that of the three groups, the images of Japan, its people and language are most favorable among students majoring in Japanese, followed by general education Japanese learners, then non learners. The study also discusses factors that form the images held by students majoring in Japanese, general education Japanese learners, and non learners. The survey indicates the similarities and differences in image formation among the three groups. According to examination about the images that students have of Japanese people, students majoring in Japanese are strongly influenced by “people”, but general education Japanese learners and non learners are less influenced by “people”. 本論文は、韓国における日本語学習者の学習動機とイメージについて研究したものである。2017年にアンケート調査を実施した結果、韓国の大学生の学習動機をみると、1位「日本・日本人・日本文化に興味がある」、2位「日本のことが知りたい」、3位「日本へ行くため」、4位「日本の漫画・アニメに興味がある。」、5位「日本の映画、テレビ番組に興味がある」であった。これによって、韓国の大学で日本語を学んでいる学習者は、日本や日本人に興味、関心をもち、日本の漫画やアニメ、映画やテレビ番組に興味があって日本語を学習しているということが明らかになった。続いて、同じく2017年の調査結果をもとに韓国の大学で専攻科目として日本語を学習している大学生と、教養日本語を履修している学生、かつて学習した経験はあるが現在は日本語を学習していない学生の、日本、日本人、日本語に対して抱いているイメージと、そのイメージを形成する際に影響を与えた要因について述べた。調査の結果をみると、大学生が日本、日本人、日本語に対して抱いているイメージは、日本語専攻者、教養日本語履修者、日本語学習の経験はあるが現在は日本語を学習していない学生(非学習者)の順に良いイメージを抱いているという結果を得た。また、日本語専攻者、教養日本語履修者、非学習者のイメージを形成した要因についても述べた。調査の結果、3つのグループにおけるイメージ形成要因の類似点と相違点が明らかになった。日本人イメージに影響を与えた要因については、日本語専攻者は「人」が影響を与えており、「非学習者」と「教養日本語履修者」は「人」の影響をあまり受けていないことが分かった。

Elements of the KKM theory on abstract convex spaces

박세희 대한수학회 2008 대한수학회지 Vol.45 No.1

We introduce a new concept of abstract convex spaces and a multimap class K having certain KKM property. From a basic KKM type theorem for a K-map defined on an abstract convex space without any topology, we deduce ten equivalent formulations of the theorem. As applications of the equivalents, in the frame of abstract convex topological spaces, we obtain Fan-Browder type fixed point theorems, almost fixed point theorems for multimaps, mutual relations between the map classes K and B, variational inequalities, the von Neumann type minimax theorems, and the Nash equilibrium theorems.
