  • 컴퓨터와 인터넷의 보급과 활용이 일반화 되고 대중화 되면서, 인터넷을 이용한 은행업무 등 비밀을 요하는 다양한 업무를 보게 되었다. 또한 인터넷, 무선통신, 그리고 자료교환에 대한 증가로 인해 많은 사용자와 접속 혹은 사용하는 방법도 빠르게 변화하고 있는 상황이다. 특히 인터넷뱅킹을 이용할 때 인터넷의 구조적인 문제점 때문에 많은 정보들이 유출되고 있고 있다. 기존의 느리고 간단한 암호화 방식으로는 인터넷뱅킹 이용할 때 신용카드 번호 혹은 통장의 계좌번호 및 비밀번호를 노출시킬 수 있다. 이러한 데이터에 대한 보안이 기대에 미치지 못하기 때문에 보다 강력한 암호처리를 필요로 하게 된다. 그러나 전송되는 자료 전체를 암호화 했을 때 소요되는 시간적 공간적 낭비 또한 무시할 수 없는 부분이다. 이에 본 논문에서는 무선기반에서 강력하게 연구되고 있는 타원곡선 알고리즘과 XML의 특징인 DTD의 부분적인 암호를 적용함으로써 보다 빠른 XML의 부분적인 암호를 구현하고자 한다.

  • This study aims to analyze the influence of financial inclusion on micro-, small-, and medium-sized enterprises' (MSMEs) performance and examine the mediation role of financial intermediation and access to capital. The object of this study is MSMEs in Malang, Indonesia. The sample consists of 100 MSME actors in Malang City, which is determined using Roscoes theory. The data is collected using Simple Random Sampling method, by distributing questionnaire measured with Likert scales. The hypotheses proposed in this study are examined using Partial Least Square (PLS) model. The results of this study show that financial inclusion influences MSMEs' performance both directly and indirectly through mediation from financial intermediation and access to capital. The direct influence means that the efforts to increase access to financial services, especially access to credit financing for MSMEs, will be able to increase market share, number of workers, sales, as well as profit of the MSMEs. Increased financial inclusion has a major impact on improving MSMEs' performance through financial intermediation compared to access to capital. This means that the increase of financial access for MSMEs followed by an increase in financial intermediation in the form of a financial service approach to MSMEs will improve MSMEs' performance.

  • The research objective was to analyze the effect of work behavior on organizational citizenship behavior (OCB) and organizational commitment. For this, we analyze the effect of organizational commitment on OCB and analyze organizational commitment as a mediating variable in the relationship between workplace behavior and OCB. This study employed survey data for 80 employees of 12 village credit institutions in the Badung Regency. Observation is one way to obtain primary data. It is done by observing the object, which is the primary source of data, and conducting direct observations of the research location to determine the circumstances and problems. This research uses data collection techniques: 1) interviews conducted with employees working in Badung Regency both in managers and staff positions. 2) Questionnaire, namely, by using several closed questions given to the Badung Regency employees regarding workplace spirituality, organizational commitment, and OCB. The analysis technique used the partial least squares (PLS) approach and the Sobel test. The results show that workplace spirituality does not affect OCB but positively affects organizational commitment. Also, organizational commitment has a positive effect on OCB. The major findings are organizational commitment acts as a mediating variable in the relationship between workplace spirituality and OCB.

  • This steel has been synthesized integrating concepts from Austempering Ductile Cast Iron (ADI) technology. While ADI has excellent mechanical and physical properties, the Young's modules of ADI is approximately 20% lower than steel. In addition, the presence of graphite nodules in ADI can be sites of crack initiation, where fracture takes place at graphite matrix interface. Because of this limitations of ADI, there has been a growing interest in austempered steels as structural materials in resent years. In this investigation, a new steel with microstructure composed of ferrite and austenite and with simultaneous high tensile strength (1,150 MPa) and high ductility (33%) was developed. The goal of this investigation is to obtain a better understanding of deformation and transformation behaviour in high carbon retained austenite(${\gamma}_{HC}$) and over-saturated ferrite(${\alpha}$) during the plastic deformation. A detailed study of the microstructure of this steel was carried out by means of X-ray diffraction (XRD) and electron back scattering diffraction (EBSD) technic. In this way it was shown that BCC phase (BCC) took up the larger part of the nominal strain whereas the a part of retained austenite responded to the mechanincal load by partial martensite transformation, and misorientation change in the retained austenite after plastic strain could be attributed to the large elongation.

  • This paper diagnoses the financial knowledge of the college students and their values on financial situation. Another emphasis is given to the classification of surveyed college students based on their financial knowledge and values and the financial traits of each classified group is also analyzed. Statistical analysis was conducted using Cronbach's ${\partial}$, factor analysis, t-test, one-way ANOVA, and Duncan's multiple range test with total number of 733 questionnaires. Primary results of the research are as follows: First, overall score of financial knowledge was 62.65 points, showing the highest points in spending while lowest in savings and investment. Senior classes, students majoring in liberal arts, students with financial education and media experiences scored high points. Second, overall score of college students on financial values was 3.92, resulting in high points on credit and frugality but points on sharing with others were low. Thirdly, all surveyed students were classified into 4 types based on the mean scores on financial knowledges and values. Total 31.7% of students belonged to Type 1 where students scored high points on financial knowledge and values. Type 2 had about 22.4 % of students whose financial score was high but value score was low. Type 3 occupied 24.2% and this group scored low points on financial knowledge but high points on financial values. Type 4 occupied 21.8% and was a group of students whose scores for financial knowledge and values were low. Finally, Type 1 and 3 groups showed better desirable behaviors for financial management and expressed higher satisfaction status for finance than Type 2 and 4. Type 1 is a group of students whose subjective financial level was high. Monthly income was highest in Type 2 and financial stress was lowest in Type 1.

  • Background: Cross-culturally adapted questionnaires may not be comparable to their original version. Objects: To examine concurrent validity of two health-related quality of life (HRQOL) instruments for the Korean versions of EuroQOL-5 Dimension (EQ-5D) and the abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) instrument. Methods: A total of 139 cancer survivors from two rehabilitation institutes was recruited. All participants were registered for palliative rehabilitation care. Both instruments were concurrently administered by health care providers following the second bout of the rehabilitation cares. Rasch partial credit model and Spearman's correlation analysis were used to investigate: 1) dimensionality, 2) hierarchical item difficulty, and 3) concurrent validity using correlations between two instruments. Results: For the WHOQOL-BREF, all items except negative feeling, pain, dependence of medical aid, were found to be acceptable, while all items of EQ-5D were acceptable. There was an evidence of negative correlations between EQ-5D and 4 domains of WHOQOL-BREF. Two correlations were strong (EQ-5D vs. physical health domain, ρ = -0.610, 95% CI = -0.716 to -0.475) and moderate (EQ-5D vs. psychosocial domain, ρ = -0.402, 95% CI = -0.546 to -0.236). Other two correlations were weak (EQ-5D vs. social relationship and environmental domains, ρ = -0.242, 95% CI = -0.401 to -0.075 and ρ = -0.364, 95% CI = -0.514 to -0.207, respectively). Item difficulty calibrations of the two measurements were ranged from -0.84 to 0.86 for the EQ-5D and -1.07 to 1.06 for the WHOQOL-BREF. Conclusion: The study provides some supports for the concurrent validity of the two Korean versions of HRQOL instrument, with evidences of weak to strong correlations between the EQ-5D and four domains of the WHOQOL-BREF applied to various cancer survivors. Additionally, the cancer survivors appeared to have more of a tendency to view the EQ-5D items as being slightly more challenging than the WHOQOL-BREF items.

  • 본 연구에서는 기존 Bagging Predictors에 수정을 가한 Modified Bagging Predictors를 이용하여 SOHO에 대한 부도예측 모델을 제시한다. 대기업 및 중소기업에 대한 기업부도예측 모델에 대한 많은 선행 연구가 있어왔지만 SOHO만의 기업부도 예측 모델에 관한 연구는 미비한 상태이다. 금융기관들의 대출 심사 시 대기업 및 중소기업과는 달리 SOHO에 대한 대출심사는 아직은 체계화되지 못한 채 신용정보점수 등의 단편적인 요소를 사용하고 있는 것이 현실이고 이에 따라 잘못된 대출로 인한 금융기관의 부실화를 초래할 위험성이 크다. 본 연구에서는 실제국내은행의 SOHO 대출 데이터 집합이 사용되었다. 먼저, 기업부도 예측 모델에서 우수하다고 연구되어진 인공신경망과 의사결정나무 추론 기법을 적용하여 보았지만 만족할 만한 성과를 이끌어내지 못하여, 기존 기업부도 예측 모델 연구에서 적용이 미비하였던 Bagging Predictors와 이를 개선한 Modified Bagging Predictors를 제시하고 이를 적용하여 보았다. 연구결과, SOHO 부도 예측에 있어서 본 연구에서 제시한 Modified Bagging Predictors가 인공신경망과 Bagging Predictors 등의 기존 기법에 비해서 성과가 향상됨을 알 수 있었다.

  • The purpose of this study is to empirically confirm what is an important variable of organizational change by intelligent technology acceptance and whether is a difference in important variables in the organization level of acceptance of intelligent technology. Recently, business models using intelligent technologies such as chat-bots, self-driving cars, credit-prevention fraud, face recognition, and health-care are emerging. External situation factors such as artificial intelligence, big data, COVID-19, and the ESG management are changing the direction of a company's management strategy. This research method established a structural equation model. As a result of the analysis, we found that the leadership, organizational culture, and organizational cooperation variables had a positive effect on human resource development variables. Human resource development found a positive effect on the performance of intelligent technology. In addition, we found the independent variables of leadership, organizational culture, and organizational cooperation had partial mediating effects on the performance of intelligent technology. Each group of levels of intelligent technology found performance differences. The organizational culture variables appeared as important variables in all groups. On the other hand, the leadership variable appeared as an important variable in the middle and lower groups of intelligent technology. The theoretical background of this study is that the business theory was updated through artificial intelligence and intelligent technology theory. As a practical implication, the organization adopting intelligent technology is necessary to prepare a systematic plan for organizational culture change.

  • ISBP745에서는 기존 ISBP에서는 규정하고 있지 않던 해상운송장 및 도로, 철도, 내수로 운송서류를 규정하여 규정의 폭을 넓혔다. 종래의 ICC Opinion과 다르거나 없었던 ISBP745의 주요 개정사항을 요약하면 다음과 같다. 첫째, 운송루트가 복합운송이면서 선하증권을 요구한 경우 UCP600 제19조 복합운송서류 규정이 적용되는 것으로 종래의 ICC Opinion과는 다르게 개정되었다. 둘째, 신용장에서 착하인도 대리점의 주소와 명칭의 운송서류 기재를 요구할 때 이 주소가 최종목적지 또는 하역항에 위치 할 필요가 없을 뿐만 아니라 동일 국가에 위치할 필요도 없다는 규정이 신설되었다. 셋째, 여러 사람의 송하인과 한 사람의 수하인이 있는 LCL/FCL 운송의 경우에는 복수의 운송서류가 발행되는데 이에 대한 사례를 구체적으로 규정하고 있다. 그러나 운송업계에서 이러한 경우에 흔히 표시하고 있는 "LCL/FCL" 또는 "CFS/CY"의 기재를 복수의 운송서류가 요구되는 사례로 규정하지 않음으로써 실무적으로 혼란을 야기할 수 있다는 문제가 있다. 넷째, 신용장에서 분할선적이 허용되고, 복수의 운송서류가 하나의 표지서류에 따라 제시될 때 서류 제시기간의 기산일을 운송서류 중 최초의 선적일을 기준으로 한다는 규정이 신설되었다.
