; Forensic chemical reactivity of amino-acid reagents (V) and LV (Cyanoacrylate & Iodine) molecules as visualizing agent for latent fingerprints, and the general chemical reactivity of amino acids (A1- A15) and lipids (L1-L21) molecules among latent fingerprint components were reviewed from 2D-QSPR models based on the calculated intermolecular FMO energy differences (E) by the DFT method and several physical constants, respectively. And proposed the Internal Standard Substance (ISS) necessary to estimate when latent fingerprints are deposited on the evidences surface. Also the visualizing agent (V) as new amino-acid reagents 요 약: 잠재지문 현출제로서 아미노산 시약(V)과 LV (Cyanoacrylate 및 Iodine) 분자들의 법화학적인 반응성 및 지문성분 중 아미노산(A1-A15)과 지질(L1-L21) 분자들의 일반적인 화학 반응성을 DFT 방법으로 계산한 분자사이 FMO 에너지 차이(E)와 몇 가지 물리적인 상수들에 근거한 2D-QSPR 모델들로부터 각각검토하였다. 그리고 증거물 표면 상 잠재지문 유류 시기의 추정에 필요한 내부 지표물질(ISS)을 제안하였다. 또한 15종의 아미노산을 표적으로 하는 새로운 아미노산 시약으로서 전체 27종의 현출제(V)중 Zincke (B) 염 분자가 Ninhydrin 분자보다 2배 빠른 현출 반응성이 가장 큰 시약으로 재 확인되었다. 아미노산 분자(A)에 대한 아미노산 시약(V)의 지문 현출성은 현출제 내 강한 전자 끌게(0≫Σσ)의 LUMO 에너지에 의한 비가역적인 궤도조절 반응이었으며, 지질 분자(L)에 대한 흡착 반응성은 소수성(clogP) 지방산과 현출제(LV) 사이의 가역적인 소수성 친화력에 따랐다. 그러나 지질분자의 clogP 및 POL (분극율) 상수들 사이에 비례 관계로부터 지질분자와 그의 현출제(LV) 간 소수성 반응은 분극율에 의존적이었다. 특히, 잠재지문의 유류 시기를 예측하기 위한 보편적인 ISS (logP>POL)의 선택성 기준(높은 안정성 및 소수성)에 따라, 첫 번째 IS S는 Squalene(및 Cholesterol)이었지만, 두 번째 IS S는 불포화 지방산(C22) 분자로서 Erucic acid (및 Docosadienoic acid) 분자가 각각 제안되었다. Review Article 96 김혜나 · 신강일 · 김해중 · 성낙도Journal of Scientific Criminal Investigation targeting the 15 amino acids, Zincke (B) salt molecule in total 27 visualizing agent (V) has been re-identified as the best visualizing agent, which is twice as fast as Ninhydrin molecule. The fingerprint visuality of the amino-acid reagents (V) to amino acid molecules (A) was the irreversible orbital-control reaction by LUMO energy of strong electron withdrawing group (0≫Σσ) in the visualizing agents (V), and the adsorption reactivity to lipid molecules (L) was according to the reversible hydrophobic affinity between the hydrophobic (clogP) fatty acids and their visualizing agents LV. However, from the proportional relationship between clogP and POL (polarizability) constants of lipid molecules, the hydrophobic reaction of lipid molecules and their the visualizing agents (LV) was dependent on the polarizability. Particularly, according to the general criteria (higher stability & hydrophobicity) for the selection of ISS (logP>POL) to predicting the deposited timing of latent fingerprints, the first ISS was Squalene (or Cholesterol), but the second ISS was Erucic acid (or Docosadienoic acid) as an unsaturated fatty acid (C22) molecule was proposed, respectively. 잠재지문 현출제로서 아미노산 시약(V)과 LV (Cyanoacrylate 및 Iodine) 분자들의 법화학적인 반응성 및 지문성분 중 아미노산(A1-A15)과 지질(L1-L21) 분자들의 일반적인 화학 반응성을 DFT 방법으로 계산한 분자사이 FMO 에너지 차이(E)와 몇 가지 물리적인 상수들에 근거한 2D-QSPR 모델들로부터 각각검토하였다. 그리고 증거물 표면 상 잠재지문 유류 시기의 추정에 필요한 내부 지표물질(ISS)을 제안하였다. 또한 15종의 아미노산을 표적으로 하는 새로운 아미노산 시약으로서 전체 27종의 현출제(V)중 Zincke (B) 염 분자가 Ninhydrin 분자보다 2배 빠른 현출 반응성이 가장 큰 시약으로 재 확인되었다. 아미노산 분자(A)에 대한 아미노산 시약(V)의 지문 현출성은 현출제 내 강한 전자 끌게(0≫Σσ)의 LUMO 에너지에 의한 비가역적인 궤도조절 반응이었으며, 지질 분자(L)에 대한 흡착 반응성은 소수성(clogP) 지방산과 현출제(LV) 사이의 가역적인 소수성 친화력에 따랐다. 그러나 지질분자의 clogP 및 POL (분극율) 상수들 사이에 비례 관계로부터 지질분자와 그의 현출제(LV) 간 소수성 반응은 분극율에 의존적이었다. 특히, 잠재지문의 유류 시기를 예측하기 위한 보편적인 ISS (logP>POL)의 선택성 기준(높은 안정성 및 소수성)에 따라, 첫 번째 IS S는 Squalene(및 Cholesterol)이었지만, 두 번째 IS S는 불포화 지방산(C22) 분자로서 Erucic acid (및 Docosadienoic acid) 분자가 각각 제안되었다.

통제사회의 맥락에서 역량기반교육의 탈경계 현상에 대한 고찰

김혜나 인천대학교 인문학연구소 2022 인문학연구 Vol.37 No.-

글로벌 교육 거버넌스의 지배 담론이 된 역량기반교육은 지식과 비(非)지식, 교육과 비(非)교육, 학생과 비(非)학생, 공적인 것과 사적인 것 등의 경계를 해체하는 핵심적 동력으로 기능한다. 이 연구에서는 테크놀로지의 급격한 발전에 의한 사회의 교육화 메커니즘과그 속에서 구현되는 역량기반교육의 다차원적 탈경계 현상을 이해하기 위해 들뢰즈 Gilles Deleuze의 통제사회 개념을 차용한다. 규율과 통제의 중첩적, 누적적 효과 속에서 규율화된 주체를 생산하던 변별적 주형은 매 순간 스스로 변형되는 조절로 진화하며 규율사회의시공간적 인클로저를 허물어낸다. 통제사회가 가져온 인클로저의 위기는 전형적 규율기관으로서의 학교를 평생교육으로, 시험을 지속적 통제로 대체한다. 역량기반교육은 학교의장벽을 지탱해온 물리적, 상징적 공간으로부터 교육을 해방하는 ‘학습화’ 현상을 통해 거의 모든 시공간과 존재, 경험들을 자본화하여 글로벌 평생학습 시스템으로 포섭한다. 다차원의 탈경계적 운동을 통해 형성된 매끄러운 네트워크 공간에서 역량기반교육은 개체를분할하면서 동시에 연결하고 통합하는 양가적 운동을 수행한다. 이러한 분석을 바탕으로바깥 없는 통제사회의 포위 속에서 가변적 조절체계의 (탈)인간학적 표현으로 진화하는역량기반교육에 어떻게 응답할 것인지 질문한다.

The Moderated Mediating Effect of Human Resources Development and Employment Type on the Relationship between Job Burnout and Adhocracy Culture of MZ Employees

김혜나 사회혁신기업연구원 2023 혁신기업연구 Vol.8 No.2

Recently, young employees called the MZ generation share the large portion of many companies in the Korean society and more interests in the MZ employees are growing. This study is aimed at strengthening the understanding of the MZ generation as employees by exploring the relationship among job burnout, adhocracy culture, human resource development(HRD) and employment type of MZ employees under this situation. PROCESS MACRO, based on Hayes model 14 was conducted using the 7th Human Capital Corporate Dataset (HCCP) II for employees provided by Korea Research Institute for Vocational Education and Training(KRIVET). The results of this research indicate that adhocracy culture significantly affects MZ employees’job burnout and HRD. The results further reveal that HRD does not mediate the relationship between adhocracy culture and job burnout but the interaction between HRD and employment type serves as a mediating moderator to explain about the relationship between adhocracy culture and job burnout. In particular, employment type serves as a moderator to explain about the relationship among adhocracy culture, HRD and job burnout. The implications of this study and future research directions are indicated.

아나키스트 과학관에 대한 비판적 고찰

김혜나 인천대학교 인문학연구소 2018 인문학연구 Vol.30 No.-

The mega machine of science and technology controls and produces our thoughts, behaviors and being in a deceptive way more than ever, permeating every single corner of our lives. Anarchist views on science which reject all forms of domination and hierarchy would be a useful mean to understand and resist this power/knowledge associated with modern science. In this regard, this paper discusses different perspectives on science as understood in classical anarchism, epistemological anarchism, and post-anarchism, that lead to different insights into the epistemology and politics of science. Reflections on their contributions and limitations, crossing borders between modernity and postmodernity, anarchism and science, knowledge and society, could enrich our understanding of where we are and provide the opportunity for a reconsideration of anthropocentrism that they have in common.

How Are Migrants Viewed in the Eyes of Employers? Double Exclusion among Immigrants in Taiwan

김혜나,Yun Hsiang Hsu,Chih-Yu Chen,Kuo-Jung Lin 숙명여자대학교 아시아여성연구원 2020 OMNES: The Journal of Multicultural Society Vol.10 No.2

While many countries are open to those born elsewhere being part of their nation, surveys find that this acceptance comes with a certain prerequisite—that it is important to speak the dominant language. This prerequisite has been continuously observed and studied in the field of labor market performance. This study surveys 1,043 employers in Taiwan for their willingness to hire foreign brides from Southeast Asia or Mainland China. The link between the proficiency of the use of language among immigrants and direct job discrimination in Taiwanese workplaces is confirmed. Results show that vocational trainings provided by the government to immigrants are not positively associated with a willingness to hire among employers. Policy recommendations are provided with regard to the establishment of language courses.

영국 중소기업 근로자들의 롤 모델링, 리더-구성원 교환관계(LMX), 직무만족 및 재직의도간 구조적 관계

김혜나 한국외국어대학교 EU연구소 2022 EU연구 Vol.- No.64

This study intends to prove the structural relationship among role modelling, LMX, job satisfaction and intention to stay in the SMEs of the UK. 5 research hypotheses were established based on the literature related to role modelling, LMX, job satisfaction, and intention to stay. Structural equation model (SEM) analysis was implemented using Burrow’s dataset provided by the Economic and Social Research Council of the UK. From the analysis of this study, it is found that role modelling had an effect on job satisfaction, LMX had a effect on job satisfaction, and job satisfaction had an effect on turnover intention. Furthurmore, it was confirmed that job satisfaction had a mediating effect in the relationship between role modelling and job satisfaction, and job satisfaction had a mediating effect in the relationship between LMX and job satisfaction. The mediating effect between role modelling, LMX, job satisfaction, and intention to stay was proved. Based on the result of this study, it is suggested that regular leadership training programs should be provided and promoted for leaders’s participation in spite of their hectic work in the SMEs of the UK. Also, human resource development managers of the SMEs in the UK should consider running a 1:1 leadership coaching program for leaders who are busy and can’t pay much attnetion to communication or feedback with their subordinates. Lastly, the limitations of this study and future research directions are presented. 본 연구는 영국 중소기업에서 롤 모델링, LMX, 직무만족도, 재직의도간 구조적 관계를 밝히고자 롤 모델링, LMX, 직무만족도, 재직의도 관련 선행연구의 문헌을 바탕으로 총 5개의 연구가설을 설정하여 영국 Economic and Social Research Council이 제공하는 Burrow Paul Burrows, Leadership in small and medium sized enterprises [Data Collection], Colchester, Essex: Economic and Social Research Council, 2017 의 데이터셋을 바탕으로 구조방정식 모형으로 검증하였다. 총 371명의 영국 중소기업 근로자들을 대상으로 분석한 결과, 롤 모델링은 직무 만족도에 영향을 주고 LMX는 직무만족도에 영향을 주고 직무만족도는 재직의도에 영향을 미치는 것으로 분석되었다. 그리고 직무만족도는 롤 모델링, 직무만족도의 관계를 매개하는 한편 LMX, 직무만족도의 관계를 매개하는 것으로 확인되었다. 이러한 연구의 결과를 바탕으로 업무 자체만으로도 바쁜 영국 중소기업내 리더들에게 정기적인 리더십 교육훈련 프로그램을 제공하고 참여하게 독려할 것을 제안하였다. 또한 영국 중소기업의 인적자원개발 담당자들은 일에 쫓겨 부하직원들과의 소통이나 피드백에 대하여 신경쓰기 어려운 리더들을 위해 1:1 리더십 코칭 프로그램을 진행하여 개인 코치에 의한 리더 개인별 맞춤형 리더십 교육을 실시하는 것을 고려할 필요가 있음을 강조하였다. 마지막으로 본 연구의 한계점 및 향후 연구방향을 제시하였다.

Climate Change and Gender Inequality in Taiwan’s Green Industry: Why is Female Competency Development Mattered?

김혜나,Yun-Hsiang HSU 동아시아경상학회 2022 The East Asian Journal of Business Economics Vol.10 No.1

Purpose - In spite of the growing importance of Taiwanese green industry, most of employees who work in this industry in Taiwan are dominated by males. Only a few females are working in this industry and their wage is lower. This research is applying role congruity theory which explains why females share only a small portion in Taiwan’s green industry. This study addresses a research question, “How has the gender inequality and discrimination been reflected in the occupation structure of Taiwan’s green industry? How has this gender occupation structure influenced females in the green industry? Research design, data, and methodology - To find out the impact of gender role in the green industry, the dataset of the 2015 Taiwan Social Change Survey is used. Using STATA, t test has been implemented to address our research question with three hypotheses. Result -All of hypothesis were all supported. It is found there is a statistical difference in stereotypical thinking between female who work in the green industry and the non-green industry of Taiwan. The limited female representation in the green industry of Taiwan influences job matching and job satisfaction significantly. Conclusion - This study suggests the Taiwanese government should encourage STEM education for females and provide more relevant vocational education and training particularly for females competency development in the green industry. By providing vocational education and training to meet the skill needs of greener economy resilient to climate change, Taiwan s green industry will grow further and will overcome gender inequality and discrimination.

한랭 두드러기에 대한 한약 치료: 체계적 문헌 고찰 및 메타분석

김혜나,오정화,윤화정 대한한방안이비인후피부과학회 2023 한방안이비인후피부과학회지 Vol.36 No.4

Objectives : The purpose of this study is to evaluate the effects of herbal medicine treatment in patients with cold urticaria. Methods : We searched randomized controlled trials(RCTs) reporting the effects of herbal medicine for cold urticaria through domestic and international databases from their inception to September 2023. The results were summarized in tables. We assessed the risk of bias in included RCTs through Cochrane risk of bias tool and the data synthesis was conducted through RevMan version 5.4. Results : A total of 12 RCTs were included in this review and all trials compared herbal medicine alone treatment(treatment group) with western medicine alone treatment(control group). The total effective rate(TER) of treatment group was statistically higher than that of control group(RR: 1.49, 95% CI: 1.38 to 1.62, p<0.00001, I 2=65%). On the other hand, when comparing except for 1 trial with different evaluation period, the TER of treatment group was statistically higher than that of control group and heterogeneity was very low(RR: 1.36, 95% CI: 1.26 to 1.47, p<0.00001, I2=0%). And when comparing 8 trials using the total symptom score(TSS) change index as an indicator of TER, the TER of treatment group was statistically higher than that of control group and heterogeneity was very low(RR: 1.38, 95% CI: 1.26 to 1.51, p<0.00001, I2=0%). The treatment group showed more statistically significant decrease compared to the control group in TSS(MD: -2.51, 95% CI: -2.63 to –2.40, p<0.00001, I2=99%). The relapse rate of treatment group was statistically lower than that of control group(RR: 0.19, 95% CI: 0.10 to 0.40, p<0.00001, I2=0%). Mild adverse events such as sleepiness, dizziness were reported in control group and gastric discomfort was reported in treatment group. In the risk of bias assessment, many cases were evaluated as ‘Unclear risk’. Conclusions : This review found that herbal medicine alone treatment could more effective and safe than western medicine alone treatment for cold urticaria. But further well-designed researches are needed because of heterogeneity between trials and the quality of the included trials.

사이버네틱스 관점에서 본 교육과정의 미래: Tyler 모형과 그 진화에 대한 대안적 해석

김혜나 충남대학교 교육연구소 2022 교육연구논총 Vol.43 No.3

This study explores an alternative interpretation of the Tyler rationale and its evolution from a cybernetic perspective and investigates new issues to consider for contemporary curriculum studies and practices. It examines how the pros and cons of the rationale rely on dichotomous logic, seeks a different lens from the hybrid perspective of cybernetics, and reinterprets the rationale and its evolution as cybernetic mechanisms. The results reveal that the controversies in the field of cybernetics during its development provide a useful means to understand how binary elements could coexist and be combined with each other. From this perspective, the rationale goes beyond its defining dichotomies such as linearity vs. circularity, behaviorism vs. constructivism, and the mechanistic vs. systems approach. Its evolution toward action research and a competency-based education model, corresponding to the central cybernetic concepts changing from stability to reflexivity and virtuality, repeats the fractal structure of the rationale as renewed versions of technical rationality. The results raise complicated issues on curriculum control and autonomy, the relationship between curriculum and science, and the relationship between curriculum and the market. They lead to decentralization and destabilization of the curriculum by broadening the scope of the curriculum and its developers, bringing both new possibilities and unprecedented problems. 이 연구는 사이버네틱스의 관점에서 Tyler 모형과 그 진화 양상에 대한 대안적 해석을 탐색함으로써 미래의 교육과정 연구와 실천을 위해 고려되어야 할 쟁점을 규명하는 것을 목적으로 한다. 연구내용은 Tyler 모형 비판과 옹호의 이분법적 논리 분석, 사이버네틱스를 통한 이분법 극복 가능성 모색, 사이버네틱스 메커니즘으로서 Tyler 모형과 그 진화과정에 대한 재해석을 중심으로 구성된다. 연구결과, Tyler 모형에 대한 평가는 선형성 대 순환성, 행동주의 대 구성주의, 기계적 접근 대 시스템적 접근 등과 같은 이분법적 논리에 의존하고 있었다. 사이버네틱스 이론은 혼종적 정체성을 형성하며 이분법적 요소들이 공존하거나 결합하는 양상을 이해할 수 있도록 하였다. 사이버네틱스 메커니즘으로서 Tyler 모형의 재해석은 이분법적 체계로 분류할 수 없는 모형의 양가적 성격을 노정하였다. 사이버네틱스의 항상성, 재귀성, 가상성 개념을 중심으로 Tyler 모형으로부터 실행연구와 역량기반교육으로 이어지는 계보를 추적함으로써, 새로운 교육 개혁이 기술적 합리성의 갱신된 메커니즘으로써 Tyler 모형의 프랙털 구조를 반복하고 있음을 밝혔다. 이는 교육과정 통제와 자율성, 교육과정과 과학의 관계, 교육과정과 시장의 관계에 관한 쟁점을 제기하며, 교육과정과 그 개발 주체의 범위를 확장함으로써 교육과정의 정체성을 탈중심화, 탈안정화하는 것으로 나타났다.
