현재 일본에는 약 58만 명의 재일코리안이 거주하고 있다. 일본 정부와 사회로부터 다양한 차별을 극복하기 위해 민족적 주체성을 유지해왔던 재일 1세~2세들과는 달리 재일코리안 청소년기에 해당하는 재일 3세~4세들은 일본 정부의 동화정책에 의해 귀화자가 늘어나고 있는 현실이다. 이에 따라 재일코리안 청소년들의 민족정체성에 대한 관심이 고조되고 있다. 이러한 배경 속에서 본 연구는 재일코리안 청소년의 민족정체성을 결정하는 요인이 무엇인지를 밝히고, 민족정체성 확립으로부터 얻을 수 있는 긍정적인 효과들이 무엇인지를 탐색해보는 것이다. 본 연구의 주요 결과는 다음과 같다. 첫째, 재일코리안 청소년의 연령, 이름형식, 국적, 출신학교, 부모의 영향 및 한국어 능력이 민족정체성 형성에 영향을 주고 있음을 확인하였다. 둘째, 민족정체성이 잘 확립된 재일코리안 청소년은 일본으로의 귀화를 고려하지 않고 있고, 한국에 대한 관심이 높으며, 한민족네트워크에 적극적으로 참여하고 있음을 알 수 있었다. 이러한 결과는 재외한인을 민족자산으로 활용하려는 정부나 기관들에게 많은 실무적인 시사점을 제공해준다. Currently, about 58 million Korean Japanese reside in Japan. To overcome the discrimination of the Japanese government and society, the previous generation of Korean Japanese had been maintaining a strong ethnic identity in Japan. But some of Korean Japanese adolescents were naturalized by the Japanese government`s assimilation policy. As a result, Korean nationality disclaimer has been increasing. In this context, this study examines what is the determining factors of ethnic identity of Korean Japanese youth, and explores the effect of ethnic identity. The main results of this study are as follows. First, age, name, nationality, school, parental influence, and Korean language skills were confirmed as the determining factors of ethnic identity. Second, Strong ethnic identity of adolescents prevents from naturalization, increases lots of interests about Korea, and makes them positive participation in the Korean network.

Enhanced Sensitivity of Patterned Graphene Strain Sensors Used for Monitoring Subtle Human Body Motions

Lee, Sang Woo,Park, Jung Jin,Park, Byung Hyun,Mun, Sung Cik,Park, Yong Tae,Liao, Kin,Seo, Tae Seok,Hyun, Woo Jin,Park, O Ok American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.12

<P>With the growth of the wearable electronics industry, structural modifications of sensing materials have been widely attempted to improve the sensitivity of sensors. Herein, we demonstrate patterned graphene strain sensors, which can monitor small-scale motions by using the simple, scalable, and solutionprocessable method. The electrical properties of the sensors are easily tuned via repetition of the layer-by-layer assembly, leading to increment of thickness of the conducting layers. In contrast to nonpatterned sensors, the patterned sensors show enhanced sensitivity and the ability to distinguish subtle motions, such as similar phonations and 81 beats per minute of pulse rate.</P>

The chemical industry is directly and indirectly related to our lives, and It is an important industry that is indispensable to our society. We are enjoying benefits as the chemical industry evolves, but accidents caused by the increase in the use of chemicals cannot be ignored. Korea has a concentration of industrial parks and residential and commercial facilities in the metropolitan area and regional cities. In fact, there are 140,000 hazardous chemicals handles company nationwide, and 6000,000 people live within a kilometer of the site. This can have a significant impact on the nearby residents as well as the employees of the site in the event of a chemical accident. In particular, senior , children, and disabled who do not have relatively sufficient ability to cope with chemical accidents can suffer more damage than ordinary people. However, the current chemical accident evacuation planning is intend to ordinary people. and it is abstract. As a result, there are no plans for vulnerable populations the who are vulnerable to disaster. Therefore, this study analyzes the risks of the vulnerable populations compared to ordinary populations and presents measures for improvement of the evacuation planning. ALOHA and Probit Analysis Equations were used to analyse the risk. Based on this, improvement measures were analyzed in terms of physical weakness and information vulnerabilities. It was concluded that vulnerable groups take longer to evacuate than normal people, must wait for rescue after indoor evacuation, also require training and training according to the season, and methods based on individual characteristics in communicating.

Cancer-Stimulated CAFs Enhance Monocyte Differentiation and Protumoral TAM Activation via IL6 and GM-CSF Secretion

Cho, Haaglim,Seo, Youngha,Loke, Kin Man,Kim, Seon-Wook,Oh, Seong-Min,Kim, Jun-Hyeong,Soh, Jihee,Kim, Hyoen Sik,Lee, Hyunju,Kim, Jin,Min, Jung-Joon,Jung, Da-Woon,Williams, Darren Reece American Association for Cancer Research 2018 Clinical Cancer research Vol.24 No.21

<P><B>Purpose:</B> M2-type TAMs are increasingly implicated as a crucial factor promoting metastasis. Numerous cell types dictate monocyte differentiation into M2 TAMs via a complex network of cytokine-based communication. Elucidating critical pathways in this network can provide new targets for inhibiting metastasis. In this study, we focused on cancer cells, CAFs, and monocytes as a major node in this network.</P><P><B>Experimental Design:</B> Monocyte cocultures with cancer-stimulated CAFs were used to investigate differentiation into M2-like TAMs. Cytokine array analyses were employed to discover the CAF-derived regulators of differentiation. These regulators were validated in primary CAFs and bone marrow-derived monocytes. Orthotopic, syngeneic colon carcinoma models using cotransplanted CAFs were established to observe effects on tumor growth and metastasis. To confirm a correlation with clinical evidence, meta-analyses were employed using the Oncomine database.</P><P><B>Results:</B> Our coculture studies identify IL6 and GM-CSF as the pivotal signals released from cancer cell–activated CAFs that cooperate to induce monocyte differentiation into M2-like TAMs. In orthotopic, syngeneic colon carcinoma mouse models, cotransplanted CAFs elevated IL6 and GM-CSF levels, TAM infiltration, and metastasis. These pathologic effects were dramatically reversed by joint IL6 and GM-CSF blockade. A positive correlation between GM-CSF and IL6 expression and disease course was observed by meta-analyses of the clinical data.</P><P><B>Conclusions:</B> Our studies indicate a significant reappraisal of the role of IL6 and GM-CSF in metastasis and implicate CAFs as the “henchmen” for cancer cells in producing an immunosuppressive tumor ecological niche. Dual targeting of GM-CSF and IL6 is a promising new approach for inhibiting metastasis. <I>Clin Cancer Res; 24(21); 5407–21. ©2018 AACR</I>.</P>

하상훈,이영구,최장석,김영창,유현덕,서승석,안기찬 인제대학교 1997 仁濟醫學 Vol.18 No.1

한국 성인의 경추부 운동성을 연구하기 위해 20대에서 60대에 이르는 각 연령군별 남녀 20명씩 총 200명을 대상으로 최대 굴곡 및 신전 측면 방사선 사진을 이용하여 각 운동 범위를 측정하고, 이를 성별, 연령군별, 전체 운동 범위의 정도에 따른 분절 운동을 측정하였을 때 전 연령층의 경추의 평균 굴신 운동 범위은 남자 60.24±9.34˚, 여자 67.02±10.51˚로 나타났고 같은 연령 군에서 전체 운동 범위 및 분절 운동 범위는 여자가 남자보다 컸으며, 연령이 증가함에 따라 분절 및 전체 운동 범위가 감소하였다. 전체 경추 운동성이 크고 젊은 연령 군에서는 제5-6 경추간의 운동 범위가 가장 컸으며 전체 운동성이 적고 나이든 연령군에서는 제 4-5 경추간의 운동 범위가 가장컸다. 이상은 경추의 형태 및 기능과 손상 기전을 이해하고, 그 질병 및 외상을 치료하는데 기초적인 자료로써 활용될수 있다고 사료된다. The full flexion and full extension anglular ranges of motion(ROM) from C2 to C7 were measured for 200 normal subjects to examine the cervical motions in Korean population Measurements were all taken from standard lateal radiographs with flexion and extension of cervical spine. The results were as follows ; 1.The average range of motion from C2-C7 was 63.94±14.29˚. 2.The total ROMs of male were in 3rd decade;73.25±11.07˚, 4th:63.80±11.33˚, 5th:61.50±9.96˚, 6th:53.00±7.94˚, 7th:52.20±7.23˚, and those of female were in 3rd:83.00±17.00˚, 4th:70.05±16.04˚, 5th:63.85±9.60˚, 6th:63.30±8.27˚, 7th:56.50±10.78˚. So, the women had larger total and segmental ROM than men in the same age group. And as age increased, the ROM was decreased. 3.The proportion of motion at level C5-6 and C4-5 were greater than any other segment. And the greatest proportion of motion was at C5-6 in younger and high total ROM group. While C4-5 was greatest in aged, and low total ROM group. Above data could be used in apprehension of disease and trauma of cervical spine and its treatment.

Development of a New Monoclonal Antibody CC5 Using a Cervical Carcinoma Cell Line Derived from Korea Woman

Kim, Jin-Woo,Seo, Chun-Ok,Cho, Eun-Young,Kin, Heung- Kee,Kim, Sa-Jin,Hur, Soo-Young,Kim, Young-Wook,Park, Tae-Chul,Lee, Joon-Mo,Namkoong, Sung-Eun 가톨릭대학교 2000 Bulletin of The Catholic Research Institutes of Me Vol.28 No.-

Purpose : Cancer of the uterine cervix remains the leading cause of cancer death in Korean women. Conventional examinations still have limitations with regards to sensitivity and specificity in diagnosis and to monitoring for the disease. Thus, an additional specific tumor marker is needed of early detection of recurrent uterine cervical carcinoma and for estimation of patient's prognosis. Materials and Methods : Monoclonal antibodies against human cervical carcinoma were generated using hybridoma technology. These murine monoclonal antibodies were produced by fusion of spleen cells obtained from mice immunized with GUMC-6, a human cell line-of squamous cell carcinoma derived from uterine cervix, and P3-X63-Ag8 mouse myeloma cells. Results : We obtained 415 hybridomas secreting specific monoclonal antibodies to cervical carcinoma antigen continuously. Among them, one hybridoma designated CC5 that was highly reactive with cervical carcinoma was selected, and examined on the staining pattern and the reactivity with antigenic determinants of cervical carcinoma. Immunohistochemica staining revealed that CC5 monoclonal antibody reacted with all of the seven cervical carcinoma tissues, but also reacted with one of the ten (10%) normal cervical tissues. Western blot analysis showed that CC5 monoclonal antibody detected single 19.5-kDa sized protein b and in cervical cancer patient's sera. The detection rate was 88% (7/8). However, CC5 monoclonal antibody did not show any reactivity to 15 sera of normal healthy women tested. Sodium dodecyl sulfate polyacrylamide gel electrophortic(SDS-PAGE) analysis of CC5 monoclonal antibody immunoprecipitates of extracts of L-□ methionine-labeled human cervical carcinoma cells showed a major band in apparent molecular weight, 51,000 daltons. The isotype and subclass of CC5 monoclonal antibody was lgG2b in hemagglutination assay. Conclusions : We have developed a new monoclonal antibody, CC5, against squamous cell carcinoma of the human uterine cervix. Further investigation is needed to determine this monoclonal antibody as an immunodiagnostic devise for cervical cancer. (Journal of Korean Cancer Association 31(3):562-574, 1999)

This study was carried out to confirm the parasitic and developmental features of A. japonica and D. suzkii was used as a parasitic natural enemy. A. japonica attacked the D. suzukii larvae and the emergence of adults were observed from D. suzukii pupae. Black spots were observed in parasitized D. suzukii larvae. Mortality of parasitized larvae, rate of parasitic and developmental feature were investigated according to developmental stages of host, D. suzukii. Mortality and rate of parasitic of D. suzukii larvae were the highest when second instar larvae were attacked. Developmental period of parasitized D. suzukii larvae showed differences to developmental stages, but there was no significant difference in developmental stage of pupal period.
