The Impact of President Kim Dae-jung’s Beliefs on North Korea Policy

Jeong-yong Kim 한국학술연구원 2003 Korea Observer Vol.34 No.2

This article inquires into the source of the Kim Dae-jung administration’s unwavering commitment to Kim’s Sunshine Policy vis-à-vis North Korea. Although such international variables as U.S. policy towards the North helped shape South Korea’s policy, this study argues that former President Kim Dae-jung’s beliefs regarding Korean unification and strategies for North Korea policy -- developed through diverse experiences over many long years -- were pivotal. Changes in the international environment and within North Korea in the 1990s impelled Kim to more precisely articulate his thoughts on North Korea, which found expression as a Three-stage Unification Plan. During his presidency, Kim’s abiding belief in his Sunshine Policy served as a causal belief, information screen, and decision-making rule for the South Korean government as it formulated and implemented North Korea policy.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

강변여과용 수평집수관을 모사하는 파일럿 규모의 모래통 실험을 수행하였으며, 다양한 출구유속에 대한 수평집수관에서의 수두분포를 구하였다. Kim24)이 수행한 실험실 규모의 수평집수관에서의 손실수두에 Kim25)이 개발한 이론 즉, 작은 규모의 수평집수관에서의 손실수두로부터 큰 집수관의 손실수두를 계산하는 방법을 적용하여 본 연구의 관측치와 비교함으로써 Kim25)의 이론이 타당함을 알 수 있었다. 또한, 이들의 이론을 적용하여 본 연구에서의 관측치로부터 실규모 집수관에서의 수두분포를 구하는 방안을 예를 들어 설명함으로써 강변여과의 수평집수관 설계방법을 제시하였다. A pilot-scale sand-box experiment simulating a lateral of collector well used in riverbank filtration was performed, and hydraulic head distributions along the lateral were measured according to the various drawdowns at the well. The results of this experiment were compared to the predicted values obtained using a theory previously developed by Kim25) in order for its validation. This theory predicts the head loss in a large-scale lateral given the loss in a small-scale one, and to have actual values for comparison, the results from a lab-scale experiment previously performed by Kim24) were employed. Comparing the experimental values to the extrapolated value indeed confirmed the validity of the theory. A procedure to determine the hydraulic head distribution of a practical-scale lateral was also presented applying the theory to the experimental result of this study in an effort to show the process of lateral design for riverbank filtration.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Yong‑Ho Kim,Hyo‑Sang Yoo,Jeong‑Han Lee,Ik‑Hyun Oh,Hyun‑Kuk Park,Hyeon‑Taek Son 대한금속·재료학회 2021 METALS AND MATERIALS International Vol.27 No.7

In order to investigate the microstructure and mechanical properties on Al–25Cr–5Si (at%) alloy, a mixed powder with pureelements and an alloy powder using a gas atomization process were used. Fine and high purity Al–25Cr–5Si (at%) alloypowder was successfully prepared by gas atomization and densified using a spark plasma sintering (SPS) process. The overallpowder size distribution of the mixed Al, Cr, and Si elemental powders was in the range of 10–15 μm. The atomized Al–Cr–Sialloy powder was fine and spherical in morphology and difficult to be formed by intermetallic formation. Densification wasclearly confirmed at 1000 °C, with almost isolated pores formed, by clear removal of pores between particles, deformationof particles, an increase in the number of contacts, and a change in size between particles. As a result of XRD analysis ofthe sintered compacts, single phase was observed using the mixed powder, but the compact using gas atomization remainedthe alloy phase even at the process temperature. The Vickers hardness of the compacts by mixed powder was observed at59.70 Hv and the compact using gas atomized powders on the temperature 1000 °C of the Vickers hardness increased to702.6 Hv. The compressive yield strength of the compact with mixed powder was 195.24 MPa and the compressive strengthof the compact with gas atomized powder increased to 802.07 MPa. It is considered not to be decomposed by the AlCrSi,Al13Cr4Si4and Al8Cr5phases sintering process, resulting from the improvement of mechanical properties.

조혈모세포이식 환자의 삶의 질에 대한 연구 : 화학요법 환자 및 정상인과의 비교

김병수,서재홍,최철원,김열홍,김준석,김정아,손상균,김재석,이경희,이제중,정익주,곽재용,안진석,이정애,박영석 대한조혈모세포이식학회 1999 대한조혈모세포이식학회지 Vol.4 No.1

연구배경: 조혈모세포이식후 신체 및 정신적 장애의 정도가 얼마나 환자의 '삶의 질(QOL)'에 영향을 미치는지에 대하여 외국에서는 연구들이 활발히 진행되고 있다. 그러나 우리나라에서는 조혈모세포이식이 비교적 활발히 시술되고 있음에도 불구하고 이에 대한 연구가 미미한 실정이었다. 연구자 등은 우리 나라에서 조혈모세포이식을 받은 환자들의 QOL은 어떤지를 알아보고자 하는 목적으로 본 연구를 시행하였다. 방법: 본 연구에 참여한 각 기관에서 조혈모세포이식을 받고 주된 치료가 끝난 후 1999년 2월 시점에서 최소 3개월이 지나고 관해상태에서 일상생활을 영위하고 있는 재생불량성 빈혈과 급성 및 만성 백혈병 환자들을 각각 자가 및 동종 조혈모세포이식을 시행받은 조혈모세포이식군(1군)과 항림프구 글로불린, 공고요법 등으로 치료를 끝낸 화학요법군(2군)으로 분류하고 연구자 병원에 내원한 건강한 환자 보호자들로 이루어진 정상대조군(3군)을 선정하여 각각의 QOL을 비교, 분석하였다. QOL의 측정은 EORTC QLQ-C30 문항을 우리나라의 실정에 맞게 번역하여 사용하였다. 결과: 조혈모세포이식군(1군)은 53명, 화학요법군(2군)은 57명, 정상대조군(3군)은 55명 이었고, 성별, 나이, 질환별 분포, 검사시점 등에서의 유의한 차이는 없었다. 각 군간의 QLQ-C30 평균 점수를 비교한 결과, 전반적인 삶의 질에서는 1군이 73.5, 2군이 51.7, 3군이 79.3으로 2군이 1.3군보다 낮았고 역할 및 사회기능은 각각 1군이 64.3/68.9, 2군이 57.6/70.3, 3군이 85.2/85.5로 1,2군이 3군에 비하여 낮았다.(P<0.01). 또한, 오심/구토가 1군은 8.7, 2군은 4.5, 3군은 3.2로 1군이 2, 3군보다 높았으며 통증은 1군은 17.0, 2군은 19.2, 3군은 9.6으로 1,2군이 3군에 비하여 높았다(p〈0.01). 기타 신체, 감정, 인식기능 및 피로에서는 각군간에 유의한 차이를 발견할 수 없었다. 결론: 본 연구에 참여한 조혈모세포이식환자들의 전반적인 삶의 질은 화학요법을 받은 환자들보다 우월하면서 정상인들과 유사하였으나 역할기능 및 사회기증, 통증에서는 화학요법 환자들처럼 정상인들에 비하여 열악하였고 오심/구토는 화학요법 환자들 및 정상인에 비하여 심한 양상을 보였다. 그러므로 본 연구를 바탕으로 하여 국내 실정에 맞는 QOL 측정 방법을 개발하고 조혈모세포이식을 시행받는 환자들의 삶의 질에 관한 연구들이 향후 계속 진행되어야 하리라고 생각된다. Background: It is very important to endow patient with satisactory quality of life (QOL). However, little is known about QOL after hematopoietic stem cell transplantation (HSCT) in Korea. In this study we tried to measure QOL in the patients treated with HSCT and compare QOL scores with those of patients treated with usual chemotherapy and normal populations. Methods: The QOL evaluation was performed with EORTC QLQ-C30 questionnaires interpreted to Korean language. The study populations were consisted with 53 patients treated with HSCT (Group 1), 55 patients treated with usual chemotherapy (Group 2), and 55 normal populations (Group 3). The QLQ-30 scores of each group were evaluated and compaired with x² test. Results: Global quality of in group 1, 3 (score: 73.5, 79.3, respectively) were higher than that (score: 51.7) of group 2. Role and social function were lower in group 1, 2 (score: 64.3/68.9, 57.6/70.3, respectively) than those (score: 85.2/85.5) of group 3. The degree of nausea and vomiting was more severe in group 1 (score: 8.7) than those of group 2, 3 (score: 4.5, 3.2 respectively). Pain scores of group 1, 2 (score: 17.0, 19.2, respectively) were more higher than that of group 3 (score: 9.6) In other parameters of QLQ-C30, there was no significant difference between each groups. Conclusion: Our perliminary result may suggest that HSCT is not necessarily associated with deterioration of QOL. This underlines the necessity of undertaking perospective studies using reliable and well-validate methods for measuring QOL

Genome-wide investigation of a Korean synthetic breed, Woori-Heukdon using the Illumina PorcineSNP60K BeadChip

Yong‑Min Kim,Ha‑Seung Seong,Jung‑Jae Lee,Da‑Hye Son,Jin‑Su Kim,Soo‑Jin Sa,Young‑Sin Kim,Tae‑Jeong Choi,Kyu‑Ho Cho,Joon‑Ki Hong,Jung‑Woo Choi,Eun‑Seok Cho 한국유전학회 2020 Genes & Genomics Vol.42 No.12

Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

1996-1997년 겨울철에 유행한 인플루엔자의 임상역학적 분석 및 원인 바이러스의 분리

김수정,정규영,이용화,기창석,이남용,이상일,김지희 대한감염학회 1997 감염 Vol.29 No.4

목적: 인플루엔자는 매년 겨울 전 세계적인 유행을 일으키는 급성 호흡기 질환으로 높은 이환률과 사망율을 보인다. 국내에서도 1996-1997년 겨울철에 다수의 보고가 있었으나 아직 체계적인 감시가 이루어지고 있지 못하다. 저자들은 이 기간 동안 인플루엔자 바이러스 감염의 역학적 특성과 임상상을 연구하여 인플루엔자 감시의 기초 자료를 제공하고자 하였다. 방법: 1996년 10월부터 1997년 4월까지 삼성서울병원 임상병리과에 인플루엔자 바이러스 배양 검사가 의뢰된 모든 검체를 대상으로 인플루엔자 바이러스의 분리율과 유행 양상, 그리고 환자들의 임상상을 후향적으로 조사, 분석하였다. 결과: 총 461명의 환자로부터 525례의 검체가 의뢰되어 총 98명의 환자로부터 인플루엔자 바이러스가 분리되었다. 인플루엔자 A형은 54명의 소아 환자와 4명의 소아 환자로부터 분리되었다. 아형과 항원 특성 검사를 시행한 31례의 인플루엔자 A형 중 한 예에서 A/Wuhan/359/95 유사주로 확인되었고 12례의 인플루엔자 B형 중 5례에서 B/Guangdong/8/97 유사주로 확인되었다. 인플루엔자의 유행 양상은 3월과 4월 중순, 두 번의 인플루엔자 최고 분리 시점이 관찰되었고, 가장 많은 불리 빈도를 보인 연령층은 인플루엔자 A형의 경우 1세 미만이었고 인플루엔자 B형의 경우 3-5세였으며 폐렴이 가장 흔한 호흡기 질환이었다. 결론: 저자들은 3차 의료기관에서 분리된 인플루엔자 바이러스에 대한 역학적, 임상적 특성을 연구하였다. 지역사회에 대한 광범위한 연구가 아니므로 국내의 전반적 상황과는 차이가 있을 것으로 생각되지만 우리나라에서도 인플루엔자 바이러스의 이환률이 낮지 않을 것으로 생각되며, 보다 조직적이고 전국적인 인플루엔자 감시가 이루어져야 할 것으로 사료된다. Background: Although influenza has been a leading cause of global morbidity and mortality, we have few data regarding the epidemioloical and clinical characteristics of influenza activity in korea. Since an outbreak of influenza was recognized during winter of 1996-1997, we analysed the epidemiological and clinical features of influenza activity in the hospital seeting. Methods: All clinical specimens requested for isolation of influenza virus at Samsung Medical Center from October 1996 to April 1997 were included. Mardin-Darby canine kidney (MDCK) cell line was used for virus culture. Isolated viruses were confirmed with immunostain followed by subtyping. The demograpic and clinical characteristics of the patients were reviewed retrospectively. Results: Ninety eight influenza viruses were isolatd from 461 patients (21.3%). Influenza A and B virus were isolated from 58 (54 children and 4 adults) and 40 pediatric patients, respectively. One of 31 influenza A viruses was confirmed as A/Wuhan/359/95-like strain and 5 of 12 influenza B viruses were confiremd as B/Guangdong/8/97-like strains. Two distinctive peaks of influenza activity were recognized and the most common age of patients was less than 1 year for influenza A, and 3 to 5 years for influenza B. Common lower respiratory infections were pneumonia followed by croup, bronchiolitis and laryngitis. Conclusion: We analyzed the epidemiological and clinical features of influenza activity during winter of 1996-1997. Although this study was performed not in the community but in the hospital setting, the morbidity caused by influenza may not be low in Korea. Therefore, nationwide surveillance for influenza activity is warranted.
