This study s purpose was to examine the impact of loneliness, and two types of social support(functional and structural) on the suicidal ideation among elderly living alone. About 254 research participants were recruited from Seoul City and other cities in Gyeonggi-do and finished the questionnaires of loneliness, perceived social support, structural social support, and the suicidal ideation. Data were entered into multiple regression analyses. The finding of this research study indicates that loneliness was an important predictor for suicidal ideation. Thus, increased loneliness was associated with a high level of the suicidal ideation. This research study result showed a moderating effect of functional social support. However, structural social support did not moderate relationship between loneliness and suicidal ideation. This research study would provide implications for social work practices.

Shin, S-H · Lim, Y-T · Kim, T-H · Park, K-J and Kwon, M-S. Electromyographical Analysis of Muscle Activities of Upper Trunk for Ssireum Dutguri Technique. Korean Journal of Sport Biomechanics, Vol. 13, no. 1, pp. 95-108. The purposes of this study were to analyze the muscle activities and the characteristics of muscle recruiting patterns of upper trunk for Ssirum dutguri technique using three top-ranked elite Ssirum players. The EMG technique was used to record muscle activities of both right and left sides of latissimus dorsi, biceps brachii, and erector spinae. Six surface electrodes were placed on the surface of the selected muscles and one ground electrode was also attached on the back of neck(C7). One video camera was also used to record the Ssirum motion to define 4 events and 3 phases for further analysis. The raw EMG data were filtered with band pass filter (50-400 Hz) to remove artifacts and then low pass filtered (4 Hz) to find the linear envelope which resemble muscle tension curve. This filtered EMG data were normalized to MVIC for the purpose of comparion between the subjects. The results were indicated that each subject with different physical characteristics showed very different muscle activity patterns. Although Ssirum dutguri is considered as foot technique the player grasped opponent's satba(belt) with both hands when they play. Because of this reason, activities of upper trunk muscles were relatively high. However, direct comparison between upper and lower body muscles was not possible due to the lack of the data in present study. Interestingly, all threes subjects showed that erector spinae muscle activity was comparatively higher than those of latissimus dorsi and biceps brachii. This implies to reinforce back muscle as a routine of training to improve performance or to prevent back injury. implies to reinforce back muscle as a routine of training to improve performance or to prevent back injury.

이 연구는 박태준의 네이버 연재 웹툰 싸움독학 (2019.11.15~현재)과 한남동 케이하우스 (2018.12.6~2019.10.31.)에 나타난 남성 동성사회성이 어떻게 드러나는가를 분석하는 것이 목적이다. 최근 남성 청소년의 백래시와 반페미니즘 정서가 확산되고 있는 가운데, 남성 청소년에게 영향력 있는 웹툰 분석은 향후 남성 청소년을 이해하는 데 의미있는 자료가 될 것이다. 두 작품의 분석을 통해 확인한 남성동성사회성 양상은 다음과 같다. 첫째, 남성의 성장은 ‘아직’ 남자가 아닌 자들이 ‘진짜’ 남성들에게 인정받고, 둘째, 인기 있는 여성을 소유하여 성적 주체가 되며, 셋째, 이 과정에서 호모포비아와 여성혐오를 동반하는 것으로 의미화 된다. 이것이 남성의 성장이라고 인식할 때 청소년들은 지속적으로 자신을, 그리고 여성을 혐오할 수밖에 없게 된다. 이러한 분석을 토대로 본 연구는 젠더 교육과 연구의 지형의 변화와 확장을 제안한다. 여성 청소년뿐 아니라 남성 청소년 역시 하나의 젠더 범주로 묶일 수 없는 다층적이고 교차적이기 때문에, 젠더 연구와 교육에서 여성과 남성의 이분법적 시각을 벗어날 필요가 있다. The purpose of this study is to analyze how the male homosociality is revealed in the webtoons written by Park, Tae-joon. Amid the recent spread of backlash and anti-feminist sentiment among male adolescents, webtoon analysis that is influential to male adolescents will be meaningful data for understanding male adolescents in the future. The male homosocial aspects confirmed through the analysis of the two works are as follows. First, the growth of men is recognized by not yet men, and secondly, they become sexual subjects by owning popular women, and thirdly, it is meant to be accompanied by homophobia and misogyny in the process. When recognizing that this ismale growth, adolescents have no choice but to constantly hate themselves and women. Based on this analysis, this study proposes changes and expansion of the topography of gender education and research. Since not only female adolescents but also male adolescents are multi-layered and cross-sectional that cannot be grouped into one gender category, it is necessary to deviate from the dichotomy perspective of women and men in gender research and education.

This study aims at analyzing the flow characteristics of the electromagnetic pump using a linear induction motor (LIM) for transferring molten metals. The flow characteristics of the pump are simulated by magnetohydrodynamic(MHD) program. In this system, the LIM is used for transferring molten metal by electromagnetic force. The molten metal is treated as the secondary part of the LIM. Since the LIM produces an electromagnetic force in the duct, the molten metal can flow from the furnace to the reservoir. The flow characteristics of the pump are analyzed using MHD program for magnetic field of 0.1[T] in duct. In order to prove the analysis, we made a prototype electromagnetic pump using LIM.

와샤의 비틀림 가공시 재료가 파단되는 원인은 제품의 결정립이 조대화되었기 때문이라고 판정하였다. 따라서, 이와 같은 현상을 해결하기 위하여 소둔은도를 χ ℃로 약간 올려, 완전히 γ(austenite)구역으로 들어가게 하고, 소둔시간은 36분으로 단축하여 열처리하므로써, 불량품 생산량을 줄이고, 제품을 대량생산 할 수 있게 하였다. The reason of fracture during the forming of washers was thought o be due to the grain growth of the microstructure. To solve this problem, annealing temperature was slighty increased to χ ℃ so that a washer was fully austenized but annealing time was reduced to 36 minutes. By the treatment, it was enable to reduce the number of inferior goods and the mass production of the washers was possible.

Type I diabetes is caused by destruction of the pancreatic beta cells responsible for insulin-secretion. It can be induced by the drugs alloxan or streptozotocin (STZ). Both an increase in reaction oxygen free radical species and a decrease in the antioxidant defense mechanism lead to the increase in oxidative stress in diabetes mellitus. Oxygen radicals scavengers are effective in preventing diagetes in animal models. Experiments were conducted by two system. The Sprague-Dawley rats were treated with STZ intravenous injection after oral administrated Betula's extract and quercetin for a week, and were administrated them for a week. In vitro, Betula's extracts and quercetin showed a tendency towards inhibition of free radical oxidation in all. In vivo, Betula's extracts group exhibited suppression morphologic change in pancreatic islet compare quercetin group on light microscopy. The Betula's extract significantly inhibited formation of MDA compared to the STZ-induced diabetic group in pancreas.They also significantly inhibited formation of Phosphatidylcholine hydroperoxide(PCOOH) compared to the STZ-induced diabetic group in pancreas and plasma, which considered defense against destruction in beta cells. The protection by Betula's extracts may be due to scavenging of deleterious and highly reactive free radical which is generated by STZ. In streptozotocin-induced diabetic rats, the effect of Betula's extract are greater than that of quercetin. Based on this result, we concluded that Betula's extract has the ability to effectively suppress in vitro and in vivo oxidation, thereby providing additional evidence for their potential beneficial type I diabetes.
