The purpose of this research is to understand Ko Yu-seop's perception of 'contemporary emerging architecture' in the West by investigating into his two early 1930s' articles: 'On Emerging Arts, Particularly the Cutting-edge Architecture' (Jan. 1931) and 'Russian Architecture' (Dec. 1932). As a result of the investigation, it is argued that he attempted to systematically describe his contemporary architecture, fromthe concept of 'modern' to representative architectural theories, and his suggested reference list is considered meaningful since it illustrates one aspect of how modern architectural knowledge was transferred to Korea at that time. As his limitation, however, it should be pointed out that a significant part of his writing was a verbatim translation of the Japanese critic Takao Itagaki's New Art Acquisition (1930). Nevertheless, the two articles give us a valuable understanding related to his socialist tendency, his preferred commune-type city-cum-architecture that reflects the ideology, etc. Hereafter, this understanding needs to be further discussed in both study areas of art history and architectural history in Korea.

The detailed names and meanings of Korean stone pagodas have not yet been properly studied or clearly defined. Therefore, an aim of this report is to compare the detailed names of Korean, Chinese, and Japanese stone pagodas by focusing on content used previously by Ko and his students and content that is currently in use (i.e., since the Japanese colonial era). Additional objectives are to assess the significance of these names and propose an appropriate detailed draft regarding names of stone pagodas. The discussion will proceed by dividing the stone pagoda into three parts: the podium, main structure, and finial. First, the content in Luo Zhewen(羅哲文)'s "Ancient pagodas in China(中國古塔)" (1985) is considered; then, "朝鮮の石塔" (1943)-published by during the Japanese colonial era-is explored. The thesis written by Yu-Seop Ko regarding Korea's first stone pagoda and the content in "A Study of Korean Pagodas(朝鮮塔婆의 硏究)" (1948), which contains Yu-Seop Ko's posthumous works published in book form by his student Su-Yeong Hwang, Heu-Kyoung Kim are examined. to pagodas that are used today, are compared and reviewed. Since Korea, China, and Japan influence each other, pagoda-related terms are shared to some extent. In this study, these were applied to stone pagodas, and names used thus far that have not drawn criticism were studied and proposed as suitable alternatives.

This paper explores a new methodology of socio-statistical survey to classify environmental perception characteristics and to quantify atmospheric environmental sensitivity of neighboring people around a large industrial complex. In order to compensate intrinsic inclination against environmental problems, Atmospheric Environmental Sensitivity Index (AESI) is proposed as the weighted-summation of four representative questions asking the current status of the local air quality, which are chosen by the factor analysis of questionnaire. Atmospheric environmental perception is tried to be classified into interest/indifference characteristics and rational/emotional perception on environmental issues, positive/negative opinion on the solution of environmental problems. According to the chi-square cross-correlation and two-way layout analyses, it was clearly shown that environmental perception is categorized into two major groups, i.e., the positive-rational group having lower AESI and the negative-emotional group having higher AESI which means more seriously senses the status of local air quality.

This paper discusses the 3-level charge pumping (CP) method in planar-type Silicon-Oxide-High-k-Oxide-Silicon (SOHOS) and Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) devices to find out the reason of the degradation of data retention properties. In the CP technique, pulses are applied to the gate of the MOSFET which alternately fill the traps with electrons and holes, thereby causing a recombination current Icp to flow in the substrate. The 3-level charge pumping method may be used to determine not only interface trap densities but also capture cross sections as a function of trap energy. By applying this method, SOHOS device found to have a higher interface trap density than SONOS device. Therefore, degradation of data retention characteristics is attributed to the many interface trap sites.

This research aims to investigate Park Kilyong's architectural theory and critique of Gyeongseong (Seoul) buildings, expressed in his 'Overview of Modern Buildings in Gyeongseong' and 'Critique of Gyeongseong Buildings' (Samcheolli, Sept. and Oct. 1935); and 'Architectural Form of the 100% Function' and 'The Modern and Architecture (1)-(4)' (Dong-A Daily, 28 Jul. to 1 Aug. 1936). As a result, it is confirmed that Park had the functionalist theory of modern architecture, which suggests that Korean architects of the Japanese colonial period were accommodating the contemporary trend of world architecture. However, Park shows his fundamental limitations in the fact that the main content of his articles was a verbatim translation of two Japanese references (Kurata, 1927; Ishihara, 1929) without proper indications. Despite the limitations, his texts are still meaningful since he formed his own architectural theory on the basis of what he translated; and indeed his critique of Gyeongseong buildings, however simple, was based on the theory. This research makes a critical analysis of Park's functionalist theory from both the 1930s' and present points of view and compares his commentaries on Gyeongseong architecture with those by Ko Yu-seop (1932) and Hong Yunsick (1937), illustrating how Korea perceived architecture and modernism in 1930s.

Background: The external rotation (ER) exercise in performed at a 90° abduction of the shoulder joint is an effective to strengthen the infraspinatus. However, failure of the humeral head to control axial rotation during exercise can be increased the posterior deltoid over activity. Biofeedback training is an effective method of promoting motor learning and control it could look forward to activate the infraspinatus selectively by controlling the humeral head during exercise. Objects: The aim of this study was investigated that whether biofeedback for axial rotation was effective to activate selectively the infraspinatus during ER exercise. Methods: The 15 healthy males participated, and all subjects performed both ER exercise in a sitting position with shoulder abducted 90° under conditions with and without axial rotation biofeedback. Exercise was performed in a range of 90° ER, divided into three phases: concentric, isometric, and eccentric. The infraspinatus and posterior deltoid muscle activity were observed using surface electromyography. Results: Both infraspinatus activity (p < 0.01) and infraspinatus to posterior deltoid activity ratio (p = 0.01) were significantly higher with biofeedback however, posterior deltoid activity was significantly lower with biofeedback (p = 0.01). The infraspinatus muscle activity and muscle activity ratio were the highest in the isometric contraction type, and there were significant differences for all contraction types (p < 0.05). Whereas, the posterior deltoid activity was the lowest in the isometric contraction type, and showed a significant difference between isometric and other two contraction types (p < 0.05), but no significant different between concentric and eccentric contraction. Conclusion: Our results indicate that the axial rotation biofeedback during sitting ER exercise might be effective method to activating selective infraspinatus muscle and recommended to enhance the dynamic stability of the shoulder joint.

A juvenile of long-snout tonguefish, Symphurus longirostris belonging to the family Cynoglossidae, was collected from the waters around Jeju Island, Korea in August 2023. Molecular analysis revealed that our juvenile specimen was identical to S. longirostris adult from Japan (Kimura-2-parameter distance, d=0.002) based on mitochondrial DNA 16S ribosomal RNA region sequences 475 base pairs, and differed from its congeneric S. orientalis (d=0.199). The juvenile of S. longirostris has the following morphological traits: obvious dermal spots on both sides of the bases of the dorsal and anal fins; and peritoneum bluish black on its dorsalmost aspect. The juvenile of S. longirostris is also distinguished from S. orientalis in that they do not have a patch of melanophores above the abdominal cavity on the ocular-side. This is the first record of S. longirostris in Korea, and we propose a new Korean name "Gin-ko-bo-seop-seo-dae" for this species.
