A New Approach to North Korea’s Denuclearization: Lynchpin–First–Removal Roadmap

문주현 한국국방연구원 2019 The Korean Journal of Defense Analysis Vol.31 No.3

Despite the Hanoi Summit between Donald Trump and Kim Jong Un, there has been no positive sign that the North Korea nuclear problem is being resolved. To advance the denuclearization negotiations, a new approach to denuclearization must be considered, which needs to meet two objectives simultaneously: to relieve North Korea’s concerns about its regime change and to practically eliminate its nuclear capability to fabricate additional nuclear weapons and refurbish existing nuclear weapons. The new approach should consider infrastructures that would be indispensable in implementing North Korea’s denuclearization processes and stopping any attempt to proliferate North Korea’s nuclear materials and technologies amid denuclearization. Accordingly, this paper proposes a new roadmap whose key concept is to first disable and, then, gradually but completely dismantle the lynchpin nuclear facilities within 10 years. Here, lynchpin facilities are dened as key facilities that are directly related to the production of nuclear materials or other materials used when fabricating and refurbishing the key components of nuclear weapons or which would have a fatal impact on maintaining North Korea’s nuclear weapon program. Additionally, this roadmap addresses corresponding measures for denuclearization activities. This roadmap consists of three sub-periods: the lynchpin disablement period, verification and dismantling period, and manifest threat removal period. This paper also identies and incorporates into the roadmap the supporting infrastructure and possible corresponding measures to accompany the denuclearization steps.

This study aimed to analyze the characteristics of women who used outpatient services for infertility and their healthcare expenditure. Using data from the 2012-2018 Korea Health Panel Study, we constructed an unbalanced panel data of women aged 20-49 with a history of using outpatient services due to the diagnosis of female infertility (N97). Among the 13,124 observations (2,951 persons), 98 observations (59 persons, 0.7%) were diagnosed with infertility, and they were 34.7 years old on average. All were enrolled in the National Health Insurance, with a college degree or higher (83.7%), in high-income households of the 5th quintile (55.1%), and working in a regular or permanent position (36.7%). The average user fees, including covered and uncovered payments, were 1.44 million KRW per a woman and 1.45 million KRW per a couple. It accounts for about 2.3% of the total household income. Based on Andersen's Behavioral Model of Health Service Use, the predisposing factors, when women were over 35 years of age and had no children, the number of outpatient visits, user fees and its household burden were higher than those under the age of 35 and those with children. Among the enabling factors, there were differences in women's job security, husband’s education level, and household income. There was no significant difference in the outpatient visits for infertility according to the need factors, such as chronic disease and obesity status of women. This study showed that outpatient use for infertility care is concentrated on a higher socio-economic status group, and called for policy attention for women in low-income groups who may experience unmet healthcare needs for infertility treatments.

문주현,윤현섭,김종원,엄병호 한국건축시공학회 2022 한국건축시공학회지 Vol.22 No.5

이 연구의 목적은 다양한 접합상세를 갖는 프리캐스트 콘크리트(precast concrete, 이하 PC) 전단벽에 대한 BIM 모델링절차를 정립하는 것이다. 그 결과 스케치업(SketchUp)의 프로그램과 컴포넌트 기능과 IFC(Industry foundation classes)파일형식을 이용하여 BIM 프로그램에서 사용가능한 PC 전단벽 패밀리 라이브래리를 구축 할 수 있었다. 스플라이스 슬리브, 볼트 또는 용접접합공법을 이용한 PC 전단벽은 BIM 프로그램으로부터 배근된 철근들의 간섭여부와 콘크리트, 철근 및 철재재료들의 물량을 정확히 평가할 수 있었다. 평가 결과 용접접합 공법을 이용한 PC 전단벽은 판재, 볼트 및 너트를 사용하였음에도 스플라이스 슬리브로 연결된 PC 전단벽에서 사용된 재료들의 전체물량, 경제성 및 환경영향성이 비슷한 수준에 있었다. 결과적으로 볼트 또는 용접접합 공법은 PC 전단벽에서 적용가능성이 높은 공법이며, 특히 시공성까지 고려한다면 스플라이스 슬리브 공법보다도 더 유용한 연결공법이 될 것으로 판단된다. The objective of the study is to establish a BIM modeling of precast concrete(PC) shear wall withvarious wall-to-base connections. The family library of PC shear wall was established in BIM programusing component function in a IFC(Industry foundation classes) file format and SketchUp program. From the BIM program, the amounts of concrete, reinforcing bars and steel materials as well as theinterference of arranged reinforcing bars can be accurately evaluated in the PC shear walls with splicedsleeves, bolt, or welding plate connection methods. Although the additional metallic materials such assteel plates, bolts, and nuts were used in the PC shear walls with welding plate connection method,their amounts of materials, economic efficiency, and environmental impact were similar to those withspliced sleeve connection. Consequently, the bolt or welding connection is a highly applicable methodas wall-to-base connection of PC shear walls, and it was a more useful method than spliced sleevemethod, particularly considering the constructability.

문주현 한국분무공학회 2023 한국액체미립화학회지 Vol.28 No.4

Droplet impingement on solid surfaces is pivotal for a range of spray and heat transfer processes. This study aims to optimize the cooling performance of single droplet impingement on heated textured surfaces. We focused on maximizing the cooling effectiveness or the total contact area at the droplet maximum spread. For efficient estimation of the optimal values of the unknown variables, we introduced an enhanced Genetic Algorithm (GA) and Particle swarm optimization algorithm (PSO). These novel algorithms incorporate its developed theoretical backgrounds to compare proper optimized results. The comparison, considering the peak values of objective functions, computation durations, and the count of penalty particles, confirmed that PSO method offers swifter and more efficient searches, compared to GA algorithm, contributing finding the effective way for the spray and droplet impingement process.

문주현 평화문제연구소 2010 統一問題硏究 Vol.22 No.1

2009년 5월 25일 북한은 2006년에 이어 두 번째 핵실험을 감행하였다.두 번째 핵실험에 의한인공지진 규모가 2006년의 그것에 비해 크다는것이 확인됨에 따라 북한의 핵무기 개발 능력에 대한 관심이 커지고 있다.본 논문에서는 북한이 실시한 두 차례 핵실험의 추정 위력을 토대로 북한의 핵무기 개발 능력을 분석하였다.이를 위해,①20kt급 핵무기를 이용하여 핵실험 수행,② 4kt급핵무기를 이용하여 핵실험 수행이라는 2가지 시나리오를 상정하였다. 북한의 두 차례 핵실험을 통해 나타난 핵폭발 위력등을 토대로 분석한 결과,20kt급 핵무기보다는 4kt급 핵무기를 이용했을 가능성이 높은 것으로 나타났다. On May 25 2009, North Korea conducted the second nuclear test. Since it has been confirmed that the seismic magnitude caused by the second nuclear test was larger than thatby the first nuclear teston October 9 2006,manypersons have been very concerned about North Korea``s nuclear weapon development capability, in particular, whether North Korea has already completed the miniaturization of a nuclear warhead. In this paper, the nuclear weapon development capability of North Korea was assessed using the data resulting from North Korea``s nuclear tests. For this, 2 nuclear test scenarios were assumed:① a test using 20kt-yield nuclear bomb;and ② a test using 4kt-yield nuclear bomb. As a result, the estimated explosion yield of the second nuclear test shows that the possibility of using 4kt nuclear bomb is a little higherthanthatofusing20ktnuclearbomb.

문주현,박정숙 (사)한국관광레저학회 2018 관광레저연구 Vol.30 No.11

The purpose of this study was to explore the role that the Five-Factor Model played in the relationship between their job satisfaction with and job performance in the hospitality industries. For the study, using 153 self-reported survey data from hoteliers across the hotels. A multiple regression analysis were performed to determine if hotelier’s personality trait could be grouped meaningfully based on the Five-Factor Model and job satisfaction & job performance. The conclusion from results and discussions were as follows. First, five factors including neuroyicism, extraverson, openness, agreeableness, conscientiousness(OCEAN) were derived as hotelier’s personality traits. Secons, as a result of the analysis of multiple regression, the Five-Factor Model had a partially positive relation to the degree of job satisfaction (intrinsic satisfation), job satisfaction (extrinsic satisfaction), but no positive to the degree of job satisfaction (work environment) according to the hypothesis Ⅰ. Third, job satisfaction had a positive relation to the degree of job performance, especially intrinsic satisfaction according to the hypothesis Ⅱ. Therefore, this result suggested that the Five-Factor Model contributed most to job satisfaction & job performance in the hospitality industries.

문주현,심재일,윤인구 한국구조물진단유지관리공학회 2016 한국구조물진단유지관리공학회 논문집 Vol.20 No.5

본 연구에서는 경량기포 콘크리트를 이용한 육성용 토양골재의 적용성을 평가하기 위해서 고로슬래그 기반 기포콘크리트의 총 8 배합과 인공토양골재를 제조하였다. 고로슬래그 기반 기포콘크리트 배합의 주요변수는 단위결합재량으로서 100에서 800 kg/m3으로 변화하 였다. 경량기포콘크리트는 플로우, 슬러리 및 절건 밀도와 재령별 압축강도를 측정하였으며, 파쇄된 인공토양골재는 pH, 입도분포, 투수계수, 양이온치환용량(CEC), 유기물함유량(C/N비)을 측정하였다. 측정결과 경량기포콘크리트의 플로우, 슬러리 및 절건밀도와 재령별 압축강도는 단위결합재량이 증가함에 따라 증가하였다. 경량기포콘크리트의 단위결합재량이 500 kg/m3 이상인 배합의 28일 압축강도는 4 MPa 이상이었 다. 인공토양골재에 3일 이상의 15% 희석된 제1인산암모늄의 수용액침지는 pH를 저감시키는데 효과적이었다. 또한 제조된 인공토양골재는 양이온 치환용량(CEC) 측면에서 상급으로 평가되었지만 C/N비 측면에서는 조경시방서를 만족시키지 못하였다. The eight mixes and artificial soil aggregates were prepared for evaluating the practical application of lightweight foamed concrete as soil aggregates. The main parameter was unit binder content ranged between from 100 to 800 kg/m3. In lightweight foamed concrete, flow, slurry and dried density, and compressive strength at different ages were measured. In Artificial soil aggregates crushed from lightweight foamed concrete, particle size distribution, pH, coefficient of permeability, cation exchange capacity(CEC), and ratio of carbon to nitrogen(ratio of C/N), were measured. The test results showed that flow, slurry and dried density, and compressive strength at different ages of lightweight foamed concrete increased with the increasing of unit binder content. Compressive strength at age of 28, of lightweight foamed concrete with unit binder of more than 500 kg/m3, was more than 4 MPa. The ammonium phosphate immersion time of more than age of 3, was effective to decrease pH of artificial soil aggregates. In addition, artificial soil aggregates was evaluated as high class in terms of cation exchange capacity(CEC), while satisfied with value of ratio of carbon to nitrogen(ratio of C/N) recommended by landscape specification.
