This study aimed at understanding the staff recruitment process of social welfare organization and providing specific practical implications for better practice in the process. To achieve this, we have contacted a community welfare center which has decided to adopt open and multi-method approach in recruitment process. The data has been collected through in-depth interviews, participatory observation and documents review. Case study analysis has been used for data analysis. The research findings have been presented at five different processes, i.e. recruitment advertisement, documents screening, job interview, selection and result announcement, appointment. A number of themes has been raised such as 'By others faults wise men correct their own', 'Lessons from experience', 'No two men are of a mind', 'Lack of speciality in recruitment methods of social welfare organization'. These themes have been discussed in detail. In conclusion, we have made some practical suggestions for both social welfare organization and job applicants concerning recruitment process.

The study identifies the major themes for integration education program which enhances the relationship between the north Korean refugees and their south Korean hosts. The themes were selected based on qualitative analysis of the socio-cultural conflicts experienced by the refugees and the hosts in the acculturation process. Twenty-eight north Korean refugees over age 20 participated in semi-structured interviews, and two south Korean groups in close contact with the refugees, police and volunteer teachers, were interviewed in focus groups. The interviews were recorded and transcribed for categorization and coding. The study views the acculturation issue as the two-sided integration task for both the north Korean refugees and the south Korean hosts rather than as the one-sided acceptance and assimilation task for the refugees.

HPAI(Highly Pathogenic Avian Influenza) is a contagious animal disease that spreads rapidly by diffusion after the first occurrence. The disease has brought tremendous social costs and economic losses. KAHIS (Korea Animal Health Information System) is the integrated system for supporting the task of preventing epidemics. They provide decision-support information, recording vehicle visiting times and facility location, etc., which is possible by enforcing registration of all livestock related facilities and vehicles. KAHIS has accumulated spatial and temporal information that enables effective tracing of potential disease trajectories and diffusion through vehicle movements. The contact network is created utilizing spatial and temporal information in KAHIS to inform facility connection via vehicle visitation. Based on the contact network, it is possible to infer spatial and temporal mechanism of disease spread and diffusion. The study objective is to empirically demonstrate how to utilize primary spatial and temporal information in KAHIS in the form of the contact network. Based on the contact network, facilities with the possibility of infection can be pinpointed within the potential spatial and temporal extent where the disease has spread and diffused. This aids the decision-making process in the task of preventing epidemics. By interpreting our demonstration results, policy implications were presented. Finally, some suggestions were made to comprehensively utilize the contact network to draw enhanced decision-support information.

This study constructs an integrated model for university students' smart phone cyber bullying and tests interaction effects between causal and control factors. Causal factors include low self-control, differential association with cyber bullying peers, and victimization experiences; and control factors include internet ethics, perceived certainty of formal punishment, and bond to parents. This study focuses on examining how internet ethics buffers the effect of causal factors in cyber bullying. Results show that both differential association with cyber bullying peers and victimization experiences have significant effects on cyber bullying. And among the control factors, internet ethics only has a negative direct effect on cyber bullying. In addition, it is found that there are significant interaction effects between two causal factors - differential association with cyber bullying peers and victimization experiences - and internet ethics. It is also shown that there is a significant interaction effect between victimization experience and bond to parents, but a perceived formal punishment has no significant control effect. It is revealed that internet ethics is a main control factor in buffering the effects of causal factors in cyber bullying.

This study analyzed the mediator effect of fear and helping responses on relationship between familiarity and discrimination based on the contact theory. We presented typical vignettes of schizophrenia, depression and alcoholism to 922 adults randomly. All respondents were asked for direct and indirect contact experiences with mental illness, fear and helping responses and discrimination against persons with mental illness. Our findings suggest that contact theory was not supported in every types of mental disorders. In schizophrenia, fear and help were the full mediator between familiarity and discrimination. In depression, only helping response was the mediator between familiarity and discrimination. But in alcoholism, familiarity did not predict discrimination. Based on theses findings, we suggest various anti-stigma strategies depending on the types of mental disorders.

Social demand for the stability of structures lead to the development of the technology to accomplish it. The non-destructive seismic technique, which is able to assess structural integrity of infrastructures, belongs to this category. Seismic technique is focused on the measurement of seismic velocity propagating through the material, and has to utilize sensors coupled to material surface, which does not allow the testing to be performed on the fly. In this paper, a general vocal microphone, which works as a non-contact sensor, was adopted to facilitate seismic testing with mobility and efficiency improved. The target of using microphones was oriented toward quality assessment of compacted subgrade, stiffness evaluation and health monitoring of concrete structures. Experimental parametric study and field applications were performed to investigate reliability and efficiency of microphones. Finally, the optimal test configuration of microphones was suggested for resonance tests and surface-wave tests.

일반적으로 초친수 박막들은 물의 퍼짐 현상이 발생하여 빠른 건조와 함께 표면에 붙은 이물질 제거와 공기 중의 미세먼지를 흡착을 하지 않음으로써 표면에 워터스폿(water spot, 물자국)이 생기지 않고 다시 깨끗해지는 자가세정 능력을 가져 유리 및 건축자재의 표면처리 용도로써 많이 사용하고 있다. 이러한 초친수 박막을 제조하는 방법으로는 sol-gel법, 진공 증착법, 화학 기상 증착법, 스퍼터링법 등을 이용한다. 이중 스퍼터링법은 높은 증착속도를 얻을 수 있으며, 비교적 낮은 진공도에서 박막제작을 할 수 있다는 장점을 가진다. 본 실험은 RF-magnetron sputtering법을 이용하여 화학적으로 매우 안정하고 높은 투과율을 가지며 기계적 표면 경도가 우수하여 코팅용 박막으로 널리 이용되고 있는 $TiO_2$와 $SiO_2$를 Single Layer와 Double Layer인 $TiO_2/SiO_2$/Glass박막을 제작하여 초친수 특성을 분석하였다. 광학적 특성을 알아보기 위해 UV-vis spectrophotometer장비를 사용하여 측정한 결과 가시광 영역에서 80% 이상의 높은 투과율을 나타내었다. 이는 모든 박막들의 광학적 특성이 우수하여 높은 광학적 특성을 요구하는 분야에 널리 사용 될 수 있다 것이라는 것을 확인 할 수 있었다. 또한 박막의 표면을 확인하기 위해 AFM을 측정한 결과 모든 박막들은 고른 거칠기를 나타내고 있다는 것을 볼 수 있었다. 이것으로 볼때 초친수 역시 초발수 박막의 표면과 마찬가지로 일정한 패턴을 가져야 하는 것을 확인 할 수 있었다. 박막이 초친수성을 띄기 위해 가장 중요시되는 조건인 접촉각이 5도 이하인 조건을 확인을 위해 Contact Angle을 이용하여 접촉각을 측정해 본 결과 박막들은 초친수성의 조건인 5도 보다 더욱 낮은 접촉각의 측정결과를 나타내었다. 위 실험결과를 볼 때 $TiO_2$와 $SiO_2$를 기반으로 단층 혹은 다층으로 박막을 제작하면 더욱 좋은 초친수 특성을 가져 사회적으로 여러 분야에 사용 가능 할 것이라 사료된다.

In most countries, public libraries have played a role as a hub of knowledge and information, complex culture of local communities, and a third place for meeting and communication. And recent public libraries are focusing on enhancing their core competencies and expanding services using digital technologies to meet the era of digital transformation and the 4th industrial revolution. However, after the COVID-19 pandemic occurred, all public libraries are repeatedly closed, reopened, and partially closed, and all resources are devoted to providing non-contact, digital and online alternative services, and are expected to continue in the future. As a result, future public libraries are bound to face a trilemma in which digital expandability, complex cultural space, and importance as a place of knowledge and information service are conflicting. This study discoursed on the public library trilemma in the post-COVID-19 era and suggested ways to overcome it. The orientation of the future public library is the fusion and harmony of multiplicity and multipurpose, place and space, knowledge & information and complex culture, face-to-face service and remote service. The main body of a public library is not the finger (digital and non-contact), but the moon (knowledge information center).

해양사고 원인규명 통합 분석 시뮬레이션 시스템은 해양사고가 발생하는 과정(선회)을 포함하여 충돌, 좌초, 접촉, 전복, 침수 및 침몰 등의 해양사고를 유체-구조 연성 해석기법의 고도 정밀 M&S 시스템을 사용하여 과학적으로 해양사고의 원인을 분석하고 사고의 손상과정을 체계적으로 재현할 수 있는 시스템이다. 해양사고는 육상과 공중에서 발생하는 자동차와 비행기 등의 충돌이나 추락사고와는 달리 공기의 밀도보다 천배의 물에서 발생하므로 물에서 부양되고, 운동하고, 선내에 물이 침수되고, 운항 중일 때 파도도 생성시키고, 두 물체가 근접할 경우에는 압력이 압착되고, 두 물체가 스쳐 지나거나 안벽이나 해저를 근접하여 운항할 경우에는 압력이 저하되는 등 물에서의 연성효과(interface effect)를 충분히 고려하여 재현할 수 있어야 정확하게 해양사고의 원인을 규명 및 분석할 수 있을 것이다. 또한 황천에서 발생하는 해양사고일 경우에는 강한 조루, 강풍 및 해일성 파도 등을 불규칙 스펙트럼을 사용하여 정확히 구현하여야 황천에서 발생하는 해양사고의 원인을 충분히 분석할 수 있을 것이다. 이러한 해양사고 통합 분석 시뮬레이션 시스템을 이용하여 과학적이고 정확한 해양사고의 원인규명 및 분석으로 심판의 획기적인 신뢰 구축과 심판 지연에 따른 사회적 비용을 최소화하고, 해양사고의 원인과 과실 책임, 나아가서 사고 재발방지 대책수립 등에도 활용하는데도 크게 기여할 것으로 사료된다.
