In 2000s, incidence of natural disaster is increasing continuously. Therefore, the necessity of research on the effective disaster response is emphasized. Korea is not safe from natural disaster. Natural disasters like torrential downpours, typhoons have occurred more frequently than before. In addition disasters like droughts and MERS has also occurred. Therefore, needs for effective systems and algorithms to respond disaster are increased. This study covers the vehicle routing problem for effective logistics in disaster situations caused by natural disasters. The emergency vehicle route problem has different property from the general vehicle route problem. It has the property of the importance of deadline, the uncertain and dynamic demand information, and the uncertainty in information transfer. In this study, a solution that focused on the importance of deadline. In this study, the heuristic solution using the genetic algorithm are suggested.

청소년의 이중적 자아 실태와 대처방안 고찰

한수민 한국청소년학회 2020 청소년학연구 Vol.27 No.4

Adolescence is a time for finding career paths and establishing self-identities by searching for aptitudes and interests, establishing a growth path that is appropriate for you, setting goals, and providing the capacity and foundation to achieve them. Adolescence undergoes greater change than any other period in the process of growing up into an adult, and furthermore, as conditions change, the period is extended. Adolescents worry about their appearance and what others see. Adolescents use mirrors to confirm this, reflecting themselves in the mirror as much as there is little time in front of the mirror in everyday life. Adolescents see reality and other self in a mirror. Since adolescents experience a doppelganger in their daily lives, they do not have confidence in themselves when they confuse or distort themselves in the mirror with themselves, causing role conflict and confusion about identity. The doppelganger of adolescents is more confusing and difficult to give meaning to life because the difference between the ego and the real self is large. To solve this problem, programs and systems involving youth, schools, parents and society are needed. 지금까지 청소년의 정체성이나 자아확립과 관련된 수많은 연구가 있었지만, 대한민국 학계에서 자아의 이중성 문제, 특히 청소년 자아의 이중성 문제를 구체적으로 다뤘던 연구는 교육학, 사회학 등 인문, 사회과학 분야에서는 거의 없었다. 본 연구의 목적은 거울을 통해 본 자아의 이중성 문제를 청소년에 초점을 맞춰 살펴봄으로써 이런 한국 학계의 연구 미비를 극복하려 한다. 청소년기는 어른으로 성장하는 과정에서 다른 어느 시기보다 큰 변화를 겪고, 더욱이 사회적 여건이 변하면서 그 시기가 연장되고 있다. 청소년은 자신이 바라보는 외모와 타인이 바라보는 외모를 갖고서 고민하고 이것을 확인하고자 거울을 이용하는데, 일상생활에서 거울 앞에 있는 시간이 적지 않을 만큼 자신을 거울에 비추고 있다. 거울은 있는 그대로 비추기도 하지만 주변에서 미친 영향을 받은 시선으로 거울에 비친 상을 바라보기도 하기 때문에 실체와 다른 자아를 보기도 한다. 또 가상공간에서 활동하고 소셜미디어를 사용하며 상대가 하는 행동이나 반응을 보고 자신을 투영하기 때문에 가상공간이나 소셜미디어가 거울과 같은 기능을 한다. 청소년은 이렇듯 일상생활에서 이중적 자아를 경험하고 있다. 청소년이 실제 자신과 거울에 드러난 자신을 혼동하거나 왜곡할 때 자기 자신에 대한 확신을 갖지 못하며, 역할 갈등을 겪고 정체감에 혼란이 일어난다. 청소년이 갖는 이중적 자아는 실제 자아와 괴리가 클수록 혼란하고 자신의 삶에 의미를 찾아내는 것이 어려워진다. 이를 해소하려면 무엇보다 자아확립이 중요한데, 그 방법으로 칭찬프로그램 활성화, 애착감을 강화하기 위한 지원 확대, 올바른 신체 이미지 확립이 있다. 결국 청소년이 갖는 이중적 자아는 성장하는 과정에서 겪어야 하는 것이기도 하지만 이것 때문에 일어나는 문제를 예방하고 극복하기 위한 노력이 필요하다.

한수민,나영국,이한솔,손기호,전성훈,방기현,김성진,이혜진,조정원 한국약제학회 2018 Journal of Pharmaceutical Investigation Vol.48 No.5

The aim of this study was to prepare the liposome with 1,2-distearoyl-sn-glycero-3-phosphocholine, 1.2 dioleoyl-sn-glycero-3-phosphoethanolamine, cholesteyl hemisuccinate, calcein as a drug model and evaluate physicochemical characteristics such as particle size, polydispersity index (PDI), encapsulation efficiency (EE). Also, the morphology of the blank liposome (without calcein) and the calcein-loaded liposome was observed by a transmission electron microscope (TEM). The particle size and PDI of the blank liposome and the calcein-loaded liposome without tween 80 were 139.8 ± 4.497, 0.31 ± 0.03 and 150.8 ± 8.45, 0.29 ± 0.03 nm, respectively. In addition, it was confirmed that the particle size of the calcein-loaded liposome increased from 294. 6 ± 17.8 to 466.4 ± 78.4 nm when tween 80 was used from 1 to 6%. EE of the calcein-loaded liposome was 66.0 ± 0.58%, independent of the concentration of tween 80. TEM images showed that the shape of the blank liposome and the calcein-loaded liposome was round. In vitro drug release test, calcein from the liposome released approximately 20–25 and 40–50% in pH 7.4 and 4.0, respectively, with a sustained release pattern. The cellular uptake of calcein from the calcein-loaded liposome was about 1.08-fold than that from the calcein solution at 10 μM for a 2 h incubation time. These results suggest that the calcein- loaded liposome was successfully prepared, and could be an application for a hydrophilic drug in further study.

한수민,황규선,최상윤,박진우 한국방재학회 2014 한국방재학회논문집 Vol.14 No.1

In South Korea, the damage caused by typhoons and downpour has the biggest proportions in total damage. Moreover, their damagesare biased to riverside structures. To deal with the disasters like typhoons, disaster response system that takes charge of preparation,emergency response, and recovery attracts public attention. This study is concerned about the emergency response resource management. This study suggests the advanced classification algorithm, which classify disaster response resources along their attributes indynamic situation. Classification result from suggested algorithm may support decision processes under dynamic emergency. In thisstudy, we arrange the information of response resources and use PCA and Clustering analysis to classify the resources. After that, weexecute the simulation study with randomly generated dataset to examine the performance of suggested algorithm. 우리나라에서는 자연 재해 중 태풍, 호우에 의한 재산 피해가 재해에 의한 피해액의 대부분을 차지하고 있으며, 이 중 수변구조물의 피해액은 절반에 가까운 비율을 차지하고 있다. 이를 줄이기 위해 사전 예방시스템의 정비, 응급대응 및 사후 복구 시스템의 구축이 이루어지고 있다. 본 연구는 수변구조물에 발생한 재해에 대응하기 위한 응급대응 시스템의 일부인 응급대응 자원의 관리에 대한 연구이다. 본 연구에서는 수변구조물에 재해가 발생하여 응급대응이 필요할 경우에 사용되는 자원을 속성에 맞추어 분류하는 시스템을 제안한다. 해당 시스템은 이전의 경직된 계층적 분류와는 달리 알고리즘을 통한 분류를 사용하여 정보의 역동적인 변화에도 적합한 분류를 수행하며, 현장 상황에 적합한 분류를 통해 긴급한 상황의 효과적인 계획 수립에 도움이 될 것이다. 본 연구에서는 피해 정보 및 자원 정보를 정적 정보와 동적 정보로 나누고 PCA 기법과 군집 분석을 적용하여 복구자원을 분류하였다. 또한 본 연구의 효용성을 파악하기 위해 가상 데이터를 생성하여 자원분류 알고리즘을 검증하였다.

자연재난 하에서의 구호 물류 거점 계획 연구

한수민,정한일,박진우 한국방재학회 2020 한국방재학회논문집 Vol.20 No.4

The frequency of and damage caused by natural disasters are continuously increasing due to climate change and urbanization. There is growing interest in countermeasures aimed to relieve the damage caused by such disasters. Emergency logistics for relief supplies is one of the most important countermeasures. This study examines the logistics of the facility planning algorithm. Facility planning focuses on storing and providing relief supplies, as well as accommodating the victims of natural disasters. Although a similar point is noted in general logistics problems, a significant difference is also pointed out that stability must be considered for supporting stable emergency logistics. Therefore, this study evaluates the risk of the route and candidate point by considering the vulnerable site at the disaster scene and suggests the facility planning algorithm based on the genetic algorithm. Finally, the performance of the suggested algorithm is verified by conducting a simulation experiment. 기후 변화 및 지속적인 도시화로 인해 자연재난의 발생빈도 및 그로 인한 피해의 규모는 점차 증가하고 있다. 이로 인한대규모 피해의 경감을 위하여, 다양한 대응 수단에 관한 연구가 수행되고 있다. 재난 피해자를 위한 구호 물자 공급을 위한구호 물류 체계는 가장 중요한 대응 수단 중 하나로서, 본 연구에서는 이를 지원하기 위한 구호 물류 거점 계획 문제를다루었다. 구호 물류 거점 계획은 구호 물자를 비축하고, 필요 시 피해자들에게 제공하며 이재민을 수용할 수 있는 물류거점의 위치 및 규모를 선정하는 의사결정에 해당하며, 일반적인 물류시스템에서의 거점 계획과 유사한 점이 존재하지만, 일반적인 비용 최소화보다는 필요한 시점에 필요한 구호 서비스를 안정적으로 제공할 수 있도록 안정성 및 효율성을 함께고려해야 하는 차이점이 있다. 따라서 본 연구에서는 피해 현장의 취약시설을 고려하여 거점 후보 및 거점 간 경로의 위험도를평가하고, 이를 바탕으로 거점 위치 및 규모를 결정함으로써 안정성과 효율성을 함께 제고시킬 수 있는 유전 알고리즘을제시하였다. 그리고 재난 시나리오에 기반을 둔 시뮬레이션 실험을 통하여 제시된 알고리즘의 성능을 검증하였다.

학교 밖 청소년을 대상으로 한 미술치료 논문 고찰

한수민 한국기초조형학회 2023 기초조형학연구 Vol.24 No.5

This research aims to understand and support the unique situations of out-of-school adolescents. The method employed in this study involved analyzing three papers that investigated out-of-school youth in different environments. The results of the analysis are as follows: Study 1 focused on art therapy for adolescents who had left school and had become adults. These individuals were able to discover and recognize themselves in their own artistic expressions, finding meaning and promoting self-understanding and acceptance. They reported hopeful expectations for the future through improved relationships with others and positive changes in their interpersonal dynamics. Study 2 out-of-school youth preparing for independence in an evacuation center were examined. They gained an understanding of themselves and their environment from a positive perspective. These individuals reported making concrete preparations for their future with a positive outlook, experiencing the caring support of art therapists, and feeling positive about their relationships. Study 3 investigated out-of-school adolescents living at home. Through participation in art therapy, these adolescents had opportunities to resolve and regulate their anger-related negative emotions. They developed the ability to address fear associated with negative situations by using physical objects, expressed their creativity through art tools, and released their energy. This process motivated them to explore new aspirations and recognize their personal growth. Additionally, the out-of-school adolescents reported spontaneously exploring their futures through the art therapy process, which was not an intended outcome by the researchers. This study reconfirmed the positive effects of art therapy on out-of-school youth and suggests the necessity of accurately describing how significantly the method of art therapy impacted these individuals.
