자원봉사센터 종사자의 LMX가 조직몰입을 매개로 조직시민행동에 미치는 영향 연구

주현아,김근홍 한국사례관리학회 2023 사례관리연구 Vol.14 No.3

자원봉사센터는 공익성을 추구하는 비영리 조직으로서 시민사회 성장에 중요한 기반이다. 이에 본 연구를 통해 자원봉사센터 종사자들의 LMX(리더멤버교환관계)가 조직몰입을 매개하여 조직시민행동에 미치는 영향을 연구하였다. 지난 2005년 자원봉사활동기본법 시행과 함께 자원봉사의 제도적 체계가 갖춰지면서 자원봉사센터가 중간 조직적 성격을 갖춘 비영리조직으로 성장한 것은 나름 주요한 의미를 내포하고 있다. 이에 자원봉사센터 종사자들의 질적 수준을 높이기 위한 조직시민행동 영향을 연구해 보기 위해 최소 3개월 이상 자원봉사센터에 근무한 유급종사자 519명을 대상으로 설문조사 하였다. 연구방법으로 기술통계분석, 평균차이 검증, 구조방정식모델 분석을 하였다. 연구를 통해 몇 가지 의미 있는 결과들이 도출되었는데 그 내용은 다음과 같다. 첫째, LMX가 정서적몰입과 지속적몰입에 유의한 영향을 주었다. 그러나 LMX가 조직시민행동에는 영향을 나타내지 못했다. 둘째, 정서적몰입과 지속몰입이 조직시민행동에 유의한 영향을 주었다. 셋째, LMX는 정서적몰입과 지속몰입을 매개하여 조직시민행동에 영향을 주었다. 이런 연구결과들로 자원봉사센터 종사자의 조직시민행동을 향상하기 위해 LMX, 조직몰입을 높이기 위한 조직문화 개선의 필요성을 제안하였다. Volunteer centers are non-profit organizations that pursue public interest and are an important foundation for the growth of civil society. Accordingly, the effect of LMX (leader-member exchange relationship) of volunteer center workers on organizational citizenship behavior by mediating organizational commitment was studied through this study. With the implementation of the Framework Act on Volunteer Activities in 2005, the establishment of an institutional system of volunteering has a significant meaning that the volunteer center has grown into a non-profit organization with an intermediate organizational character. Therefore, in order to study the impact of organizational citizenship behavior to improve the quality of volunteer center workers, a study was conducted on 519 paid employees who had worked at a volunteer center for at least 3 months. Descriptive statistical analysis, t-test, and structural equation model analysis were conducted as research methods. Several meaningful results were derived through the study, which are as follows. First, LMX had a positive (+) effect on emotional commitment and continuous commitment. However, LMX did not show an effect on organizational citizenship behavior. Second, emotional commitment and continuous commitment had a positive (+) effect on organizational citizenship behavior. Third, LMX influenced organizational citizenship behavior by mediating emotional commitment and continuous commitment. These research findings suggested the necessity of improving LMX and organizational culture to increase organizational commitment to improve organizational citizenship behavior of volunteer center workers.

Purpose : The purpose of this study is to investigate the effect of ARTEMISIAE CAPILLARIS HERBA and COPTIDIS RHIZOMA Extracts on cell death in pancreatic cancer cells. Method : Human-derived pancreatic cancer cell line, MIA PaCa-2 cells were treated by Prescription A with various concentrations and the cytotoxicity was determined by MTT assay. To investigate the effects of Prescription A on pancreatic cancer cells, the staining of Annexin V/PI, cell cycle arrest, nuclear chromatin condensation and the production of reactive oxygen species (ROS) were examined. The effect of Prescription A's effective components, ARTEMISIAE CAPILLARIS HERBA and COPTIDIS RHIZOMA Extracts on cell death were also observed. Results : The viability of MIA PaCa-2 cells treated with Prescription A were decreased in a dose dependent manner. Prescription A induced cell death in MIA PaCa-2 cells as shown by result of Annexin V/PI double staining, chromatin condensation and cell cycle arrest. In addition, production of ROS was increased by Prescription A treatment, suggesting that ROS induced by Prescription A mediated cell death. Furthermore, Prescription A's effective components, ARTEMISIAE CAPILLARIS HERBA and COPTIDIS RHIZOMA Extracts were also induced apoptosis of MIA PaCa-2 cells through ROS production. Conclusion : These results suggest that Prescription A's effective components, ARTEMISIAE CAPILLARIS HERBA and COPTIDIS RHIZOMA Extracts induced death of MIA PaCa-2 through ROS production.

Objective : The purpose of this study is to investigate about comparison of Eastern-Western medicine on the acne. Methods : We searched Eastern and Western medicine books for acne. We analyzed these books and examined category, definition, etiology, classification, internal and external methods of treatment of acne. Results : The results were as follows. 1. In Eastern medicine, Acne belongs to the category of the Bunja(粉刺), Jwachang(?瘡), Pyepungbunja(肺風粉刺). In Western medicine, the other name of Acne is acne vulgaris. 2. In Eastern medicine, the definition of Acne includes manual extraction of comedones and skin appearance. In Western medicine, Acne is a common skin disease during adolescence and a chronic inflammatory disease of pilosebaceous unit of self localization. It is characterized by noninflammatory, open or closed comedones and by inflammatory papules, pustules, and nodules and it affects the areas of skin with the densest population of sebaceous follicles, these areas include the face, neck, back, and the upper part of the chest. 3. In Eastern medicine, the cause and mechanism of Acne arose from the state of internal dampness-heat and spleen-stomach internal qi deficiency due to dietary irregularities and then invaded external pathogen such as wind-dampness-heat-cold-fire in lung meridian lead to qi and blood heat depression stagnation. So it appears in skin. In Western medicine, the etiology and pathogenesis of Acne is clearly not identified, but there are most significant pathogenic factors of blood heat depression stagnation. So it appears in skin. In Western medicine, the etiology and pathogenesis of Acne is clearly not identified, but there are most significant pathogenic factors of Acne; Androgen-stimulated production of sebum, hyperkeratinization and obstruction of sebaceous follicles, proliferation of Propionibacterium acnes and inflammation, abnormaility of skin barrier function, genetic aspects, environmental factors etc. 4. In Eastern medicine, differentiation of syndromes classifies clinical aspects, and cause and mechanism of disease; the former is papular, pustular, cystic, nodular, atrophic, comprehensive type; the latter is lung blood heat, intestine-stomach dampness-heat, phlegm-stasis depression, thoroughfare-conception disharmony, heat toxin type. In Western medicine, it divides into an etiology and invasion period, and clinical aspects; Acne neonatorum, Acne infantum, Acne in puberty and adulthood, Acne venenata; Acne vulgaris, Acne conglobata, Acne fulminans, Acne keloidalis. 5. In Eastern medicine, Internal methods of treatment of Acne are divided into five treatments; general treatments, the treatments of single-medicine and experiential description, the treatments depending on the cause and mechanism of disease, and clinical differentiation of syndromes, dietary treatments. In Western medicine, it is a basic principles that regulation on production of sebum, correction on hyperkeratinization of sebaceous follicles, decrease of Propionibacterium acnes colony and control of inflammation reaction. Internal methods of treatment of Acne are antibiotics, retinoids, hormone preparations etc. 6. In Eastern medicine, external methods of treatment of Acne are wet compress method, paste preparation method, powder preparation method, pill preparation method, acupuncture and moxibustion therapy, ear acupuncture therapy, prevention and notice, and so on. In Western medicine, external method of treatments of Acne are divided into topical therapy and other surgical therapies. Topical therapy is used such as antibiotics, sebum regulators, topical vitamin A medicines etc and other surgical therapies are used such as surgical treatments, intralesional injection of corticosteroids, skin dermabrasion, phototherapy, photodynamic therapy, and so on. Conclusions : Until now, there is no perfect, effective single treatment. We think that Eastern medicine approach and treatment can be helpful to overco

In recent, entering the era of economic decline and low growth, the emergence of the Yolo who live for the present happiness rather than the future, the growth of beauty products based on lipstick effects, and the small luxury related to the expansion of the luxury dessert market are shown. The Yolo, lipstick effect, and small luxury have similarities and differences in their interrelation. What they have in common is driven from the recent recession or slow growth. On the other hand, it is known that the psychological mechanism that an individual feels and solves such external influences is somewhat different even if it is influenced by the external environment of the economic recession. In this study, rather than rigorously classifying the concepts of the Yolo, lipstick effect, and small luxury, we first identify the economic recession and the consumption items that represent this phenomenon. The key variables analyzed in this study are the relationship between recession and consumption by item. Unemployment rate data were used to measure the recession. Consumption by item is selected from five items such as coffee and tea, sports and entertainment services, toys and hobbies, beauty and beauty services, and cultural services, which are inferred to be related to the phenomenon of Yolo, lipstick effect, and small luxury. Unemployment rate data and consumption expenditure data by item from 2006 to 2016 were used. As a result, the unemployment rate has a positive effect on consumption expenditure of coffee·tea and beauty ·beauty services. The unemployment rate has been found to have a significant negative impact on the consumption of sports·entertainment services and the consumption of toys·hobby goods. Unemployment rate has no significant influence on cultural services. Finally, implications, limitations, and future research directions are presented. 최근 경기 불황 및 저성장 시대에 진입하면서 미래가 아닌 현재의 행복을 위해 사는 욜로족의 등장, 립스틱 효과에 기초한 뷰티 상품의 성장, 그리고 고급 디저트 시장의 확대와 관련이 있는 작은 사치와 같은 용어들이 범람하고 있다. 욜로족, 립스틱 효과, 작은 사치는 상호 관련성에서 유사한 점도 있고 서로 다른 점도 있다. 이들 간의 공통점은 최근 경기 불황 혹은 저성장과 관련되어 있다는 것이다. 반면에 경기 불황이라는 외부 환경에 의해 영향을 받더라도 개인이 그러한 외부 영향을 느끼고 해결하는 심리적 기제는 다소 다른 것으로 알려져 있다. 본 연구에서는 욜로족, 립스틱 효과, 작은 사치를 엄격하게 구분한 후, 그에 대한 심리적 기제를 파악하기 보다는 우선적으로 경기 불황과 이러한 현상을 대표할 수 있는 품목들을 추출하여 이들 품목과의 소비 관련성을 실증하는데 있다. 본 연구에서 분석되는 핵심 변수는 경기 불황과 품목별 소비 간의 관계이다. 경기 불황을 측정하기 위해 실업률 자료가 이용되었다. 품목별 소비는 가계의 소비지출 중에서 립스틱 효과, 욜로족, 작은 사치 등과 관련이 있다고 추론되는 커피 및 차, 운동 및 오락서비스, 장난감 및 취미용품, 이·미용서비스, 문화서비스와 같이 5개의 품목을 선택하였다. 2006년부터 2016년까지의 실업률 자료와 품목별 소비지출 자료가 이용되었다. 분석 결과, 실업률은 커피 및 차와 이·미용서비스의 소비지출에 긍정적인 유의한 영향이 있는 것으로 나타났다. 실업률은 운동 및 오락서비스와 장난감 및 취미용품의 소비지출에는 부정적인 유의한 영향이 있는 것으로 밝혀졌다. 실업률은 문화서비스에 유의한 영향력이 없는 것으로 나타났다. 마지막으로 연구결과에 대한 시사점, 한계점, 그리고 향후 연구방향이 제시되었다.

범죄예측 및 형사사법절차에서 알고리즘 편향성 문제와 인공지능의 활용을 위한 규범 설계

주현경,정채연 조선대학교 법학연구원 2020 法學論叢 Vol.27 No.1

인공지능 기술의 활용 영역이 다방면으로 급속하게 확대되면서, 과연 인공지능이 인간의 법적·사회적 규범 및 윤리적·도덕적 가치를 내면화할 수 있는지 여부에 대한 관심이 증대되고 있다. 많은 사례들을 통해 인공지능이 인종 및 성, 그리고 경제적 격차에 따른 차별과 편견 등 인간사회의 부정적인 관점 역시 학습할 수 있다는 위험성이 대두되면서 인공지능 기술에 기반한 자동화된 의사결정이 갖는 근본적인 문제점들이 지속적으로 제기되고 있다. 인공지능의 윤리적 프로그래밍을 위한 다양한 방법론들이 제시되어 왔지만, 이는 여전히 대표적인 난제로 손꼽힌다. 또한 인공지능을 개발한 프로그래머조차도 인공지능의 의사결정이 어떠한 논증 과정을 거쳐 산출된 것인지를 정확히 파악할 수 없다. 명확하게 언어로 설명 가능한 분석 및 추론에 바탕을 두기보다는 일종의 블랙박스와 같다고 할 수 있는 인공지능 알고리즘의 의사결정체계로 인해, 인간사회의 규범적 가치가 인공지능의 의사결정과정에 개입할 여지는 극히 낮아지게 된다. 이에 따라 인공지능의 의사결정에 지나치게 의존하게 되면 법적 정당성 및 규범적 당위성을 계산적 확실성 및 수학적 합리성이 대체하게 되는 위험을 초래할 수도 있는 것이다. 인공지능의 활용이 본격화되면서 인공지능의 윤리화와 알고리즘의 편향성에 대한 문제가 제기되고 있는 대표적인 영역은 바로 범죄예측 및 형사사법절차이다. 특히 빅데이터 기반 인공지능으로 인해 수사, 공판, 형집행 전(全) 단계는 물론 범행 전(前) 범죄예측 단계에서부터, 범죄 관련 데이터가 축적되고 이를 사법절차에서 활용할 가능성이 논의되면서, 절차상 보장되어야 할 인권과 절차적 정의는 그 어느 때보다도 강조된다고 할 것이다. 이러한 맥락에서 인공지능이 인간사회에서 보편적으로 승인된 도덕원칙을 내면화하고 이를 바탕으로 가치판단을 내릴 수 있는지 여부에 대한 법이론적 검토와 더불어 인공지능 알고리즘의 의사결정에 규범적 테두리를 설계하는 것이 앞으로의 과제가 될 것이다. 본 논문에서는 특히 범죄예측 및 형사사법절차에서 인공지능 기술의 활용 가능성에 집중하여, 예측적 치안 및 재범 예측 분야에서 인공지능 알고리즘의 자동화된 판단이 수반하는 알고리즘 편향성을 검토하고, 이러한 편향성의 문제를 해결하기 위한 규범설계의 필요성을 확인한 후, 법치국가원칙을 보장하면서 알고리즘 투명성 및 책무성을 확보하기 위한 규범적 테두리를 구상해보고자 한다. As the scope of application of artificial-intelligence (AI) technology expands rapidly, there is an increasing interest in the question of whether AI can internalize legal-social norms and ethical–moral values. Fundamental problems in AI decision-making processes are constantly being raised following numerous cases that exposed the risk of AI’s capacity to learn societal biases, such as those based on racial, gender, or economic inequality. Although various ways have been presented to program AI ethically, the abovementioned problems still remain a serious challenge. In addition, even programmers who develop AI systems are unable to accurately determine how AI’s decisions are made and under what logical processes. Due to its nature of the decision-making process that can be likened to a black box rather than one based on analysis and inference explicitly explainable in words, the possibility of human normative values to be incorporated into AI decision-making process becomes almost nil. Therefore, it is highly likely that relying on AI algorithms for legal decisions will lead to a situation where legal and normative legitimacy would be replaced by computational certainty and mathematical rationality. With the advent of AI, crime prediction and criminal justice are the most controversial areas in which problems with the ethics of AI and algorithm bias are raised. In particular, as big-data-based AI allows the collection of crime-related data during not only the pre-sentencing stages, such as the investigation and the trial, but also before the offending―this may be considered as de facto crime prediction―, and as the possibility of their use in the judicial process is being discussed, human rights and procedural justice that should be guaranteed in the criminal procedure should be emphasized more than ever. In this context, the challenges ahead will be to internalize the universally accepted moral principles in AI, examine applicable theories in jurisprudence on whether AI has the capacity to make value judgments based on such principles, and suggest legal policies to establish the framework for decision-making by AI algorithms. This article focuses on the application of AI technology in criminal justice, examines the fundamental rights of defendants and prisoners in light of the rule of law in criminal procedure, and highlights normative standards to resolve the problem of algorithm bias, thus guaranteeing the relevant stakeholders’ right of access and ensuring the transparency of AI algorithms.

NVH 해석기술을 활용한 엔진 블록 박육 경량화 개발

주현철(Hyeon Cheol Joo),김태정(Tae-Chung Kim),이수호(Su Ho Lee),정병환(Byung Hwan Jung) 한국자동차공학회 2009 한국자동차공학회 학술대회 및 전시회 Vol.2009 No.11

Prediction of NVH performance of an engine block at the initial design stage is important, because NVH characteristics of a structure are related to global stiffness balance, not to local band-aids. The NVH performance of an engine structure is related to skeleton stiffness, skirt radius, flange and tubing locations altogether. In this paper, an example of NVH characteristics prediction using CAE is presented first. These results are compared to measured experimental results to prove its reliability, and the CAE prediction technique is adapted into a challenging light-weight thin-wall engine block development. Necessary modifications are tried and verified with CAE, and finally a weight reduction of 11.2㎏ is achieved with better NVH performance than current mass-production units.
