남가인 ( Nam¸ Ga-in ),박성혜 ( Park¸ Sung-hae ) 한국미술심리치료연구학회 2021 미술심리치료연구 Vol.1 No.1

본 연구는 청소년의 SNS 사용 기간과 SNS 일일 평균 사용 시간에 대한 중독 경향성을 살펴보고 성별에 따른 SNS중독경향성과 나무그림검사 반응특성을 비교한 연구결과를 토대로 SNS중독경향성에 대한 나무그림검사의 활용가능성을 확인하고자 하였다. 연구대상은 강원지역 소재의 고등학생 280명으로 SNS중독경향성과 나무그림검사를 실시하였다. 부모동의가 없었던 34부를 제외한 총 246부를 SPSS 25.0 프로그램을 사용하여 독립표본 t 검정 및 분산분석과 사후검증을 실시하였다. 본 연구에서 밝혀진 결과를 요약하면 다음과 같다. 첫째, 고등학생의 성별, SNS 사용 기간, SNS 일일 평균사용 시간에 따른 SNS중독경향성을 살펴본 결과 여학생이 남학생보다 SNS중독경향성이 높았으며, SNS 사용 기간과 SNS 일일 평균사용 시간이 길수록 SNS중독경향성이 높게 나타났다. 둘째, 남학생의 SNS중독경향성이 높은 경우 용지의 2/3 이상, 용지의 1/3 이상 2/3 이하에서 진한(강한)선 표현에서 유의미한 차이가 나타났으며, 내용적 분석에서는 각지거나 거칠거칠함, 상흔이나 옹이, 혼잡한 선으로 된 수관 표현이 많았다. SNS중독경향성이 낮은 경우 나무 그림의 뿌리 생략, 가지마다 2획 가지가 풍부하게 나뉘는 표현이 유의미하게 나타났다. 여학생의 경우, 형식적 분석에서 용지의 2/3 이상, 용지의 1/3 이상 2/3 이하에서 진한(강한)선 표현, 언덕 위나 섬 위의 지면선, 내용적 분석에서 수관의 생략, 가지 끝이 예리한 경우, 각지거나 거칠거칠함, 선이 둥글고 곡선적인 줄기 등에서 표현이 유의미하게 나타났다. 본 연구 결과를 바탕으로 SNS중독경향성이 높은 고등학생의 자기개념과 충동이나 불안 등의 심리적인 어려움을 측정할 수 있는 그림 검사 도구로서 나무그림검사의 활용 가능성을 확인하였다. This study was to examine the addiction tendency on SNS using time and SNS average daily using time of adolescents, to compare characteristics of responses to Tree-Drawing Test by the degree of SNS addiction tendency according to gender, and to identify the applicability of Tree-Drawing Test on SNS addiction tendency based on the study results. 280 high school students who were attending in high school located in Gangwon province were the study subjects, and Tree-Drawing Test and survey were conducted. A total of 246 data were analyzed by using SPSS 25.0 program except 34 data of collected data that were omitted from the survey or that didn't get parental consent. In addition, t-test was conducted to verify the differences by each variable and potential for utilization of Tree-Drawing Test was verified. Results of the study can be summarized as follows. First, the results of examining the SNS addiction tendency by the gender, SNS using time and SNS average daily using time of high school students showed that female students had higher SNS addiction tendency than male students, and the longer the SNS using time and SNS average daily using time, the higher SNS addiction tendency. Second, in case of male students with high SNS addiction tendency, significant differences were shown in the expression of thick (strong) line in more than 2/3 of the paper and more than 1/3 and less than 2/3 of the paper. In case of content analysis, there were many expressions of tree crown shown with angular form, roughness, scars or knots and a jammed lines. In case of low SNS addiction tendency, the expression that omits roots from tree drawing and richly divides branches with 2 strokes was significant. In case of female students, the expressions of thick (strong) lines and ground line on a hill or on an island in more than 2/3 of the paper and more than 1/3 or less than 2/3 of the paper were significant in the formal analysis, and the expressions of the omission of tree crown, sharp end of the branch, angular form or roughness and rounded and curved stems were significant in the contents analysis. Based on the results of the study, we found the possibility of using Tree-Drawing Test as a drawing test tool that can measure the psychological difficulties such as impulse or anxiety of high school students who have high SNS addiction tendency.

Microstructure control of continuously porous t-ZrO₂ bodies fabricated by multi-pass extrusion process

Gain, Asit Kumar,Lee, Byong-Taek Elsevier 2006 Materials science & engineering. properties, micro Vol.419 No.1

<P><B>Abstract</B></P><P>Continuously porous t-ZrO<SUB>2</SUB> bodies having different pore sizes were fabricated using the multi-pass extrusion process. The pore size depended on the number of extrusion passes, the extrusion ratio, and rod diameter and tube thickness. The pore size dramatically decreased as the number of extrusion passes and tube thickness increased. The pore sizes of the 2nd passed samples, which were made by a feed roll using different rod diameters and tube thickness, were about 260, 180, 150 and 90μm in diameter while the 3rd passed samples which were made with different extrusion ratios (40:1 and 61:1) were about 80 and 35μm in diameter, respectively. In the 2nd passed t-ZrO<SUB>2</SUB> bodies sintered at 1550°C, the relative density and bending strength decreased as the pore size increased. In the 3rd passed sample having a pore size of 35μm, the bending strength increased as the sintering temperature increased up to 1550°C. The maximum bending strength of the 3rd passed t-ZrO<SUB>2</SUB> body was about 297MPa.</P>

Many advanced countries have established their own Extended Producer Responsibility (EPR) systems in various types of target products, recycling obligation, Producers Responsibility Organization (PRO) management and performance management. This study examines a comparative analysis for EPR systems in selected countries (South Korea, UK, Germany, France, and Belgium). This study was conducted by literature review of published reports and papers, interviews of experts, and analysis reports and data of EPR system published by OECD and EU. In these countries, producers are required to join and contribute to PRO or to fulfill their recycling obligations. PRO is obligated to recycle it with the procured funds. In the case of Germany, there are 10 PROs available throughout the country with a competition basis, while in France and Korea, there is only one PRO available for packaging materials and the local governments are obliged to collect and sort the packaging waste. This comparison analysis could help to identify the characteristics of EPR systems in selected countries and to give policy-makers a direction for effective decision-making.

Histopathological features and viral genome detection in caprine arthritis encephalitis virus infected dairy goats in Korea

( Gain Son ),( Eun-sang Cho ),( Hyun-jin Shin ),( Hwa-young Son ) 한국가축위생학회 2017 韓國家畜衛生學會誌 Vol.40 No.3

Caprine arthritis encephalitis (CAE) virus is a causative agent of caprine arthritis-encephalitis. In our previous study we reported a prevalence of CAE. In this study, we described the further detailed pathological features of CAE and examined the detection of virus by in situ hybridization (ISH). Histopathologi-cally, interstitial pneumonia and bronchopneumonia in lung, focal inflammation in mammary glands, perivascular cuffing in brain, arthritis, and focal necrosis, mild steatosis, inflammatory cell infiltration of liver were noted. CAEV proviral-DNA was identified by nested polymerase chain reaction (PCR) in blood cells, brain, synovial fluid, and lymph node. Confirmation by nested PCR involved amplification of a 296 bp (1^st PCR) and 185 bp (2^nd PCR) fragments corresponding to a conserved region on the gag gene of CAEV. Positive ISH signals were detected in the brain and liver. In conclusion, significant histopathological findings included parenchymal infection in various organs, including the lung, liver, brain, joint, and mammary gland were noted in the CAEV infected dairy goat. ISH can help confirm the diagnosis of CAE in formalin-fixed samples.

Occurrence, Distribution and Risk Assessment of PAHs in Road Dust Sediment in Daejeon Metropolitan City, South Korea

Gain Lee,Yong-Chul Jang,Kyunghoon Choi,Hongkyoung Kim,Seungmin Ji,Byeonghwan Kim,Youngsun Kwon,Ho-Sang Shin 대한환경공학회 2023 Environmental Engineering Research Vol.28 No.2

In this study, the occurrence and distribution of polycyclic aromatic hydrocarbons (PAHs) in road dust sediment(RDS) deposited from main traffic roads as well as residential and industrial areas were examined with a total of 144 samples in seasons. Based on the results, the concentrations of PAHs were found to be higher in winter and ranged between 0.15 and 1.94 ㎎/㎏ with an average of 0.65 ㎎/㎏. The results indicate that pyrene, fluoranthene, phenanthrene, and benzo(ghi)perylene were commonly found in RDS, likely originated from vehicle exhaust emissions and fuel combustion by the diagnostic ratio study. Non-cancer risk from PAHs for humans exposed to RSD was found to be low (HI 1.2E-05). The estimated excess cancer risks by PAHs in RDS was also much less than the regulatory guideline for cancer risk (1×10<SUP>-6</SUP>). Thus, current concentrations of PAHs in RDS are expected to be pose no threat to humans under the assumed exposure scenarios with applied exposure factors. However, more extensive and long-term sample analysis for gaseous and particulate PAHs is still warranted to determine potential risks to humans and the fate in the environment, since their concentration and distribution can be influenced by micro-metrological conditions, traffic volumes, or road clean-up conditions.

The Impact of Social Distance on Mask Wearing Behavior A Construal Level Perspective

Gain Park,Myungok Chris Yim 한국PR학회 2021 PR연구 Vol.25 No.1

Objectives This study investigates the relationship between the perceived social distance, risk perception, and mask-wearing intentions. It further tests the interaction effect between the social distance perception and message intervention framed by two distinctive construal level terms (high-level and low-level) on mask-wearing intentions. Methods The first survey interrogates what delineates the most relevant social distance dimension that presumably feeds judgments about susceptibility to COVIDᐨ19. It is followed by a 2 X 2 factorial survey experiment (between groups) that examined the reciprocal effect of social distance and construal level (CLT) on behavioral intentions to wear a face mask as a COVIDᐨ19 preventive measure. Results Our finding substantiates social distance perception and its influence on the perceived susceptibility to COVIDᐨ19 and how social distance and construal level interact with one another to impact the individuals' willingness to wear a face mask. Conclusions The results suggest how policymakers and health campaign planners apply construal level framing to moderate the effect of social distance perception on preventive health behaviors.
