In this paper, we propose an algorithm that enables near-field delivery at a faster and lowest cost to meet the growing demand for delivery services. The algorithm proposed in this study involves subway passengers (shipper) in logistics movement as delivery sources. At this time, the passenger may select a delivery logistics matching subway route. And from the perspective of the service user, it is possible to select a delivery man whose route matches . At this time, the delivery source recommendation is carried out in a text similarity measurement method that combines TF-IDF&N-gram and BERT. Therefore, unlike the existing delivery system, two-way selection is supported in a man-to-man method between consumers and delivery man. Both cost minimization and delivery period reduction can be guaranteed in that passengers on board are involved in logistics movement. In addition, since special skills are not required in terms of transportation, it is also meaningful in that it can provide opportunities for economic participation to workers whose job positions have been reduced. 본 연구에서는 급증하는 배송 서비스 수요에 맞춰 더 신속하고 최저 비용으로 근거리 배송을가능하게 하는 알고리즘을 제안하고자 한다. 본 연구에서 제안하는 알고리즘에서는 배송원으로지하철 승객을 물류 이동에 참여시킨다. 이때 승객은 이동 경로와 일치하는 배송 물류를 선택할수 있다. 그리고 서비스 이용자의 입장에서는 현재 근처에 경로가 일치하는 배송원을 선택할 수있다. 이때 배송원 추천은 TF-IDF&N-gram과 BERT를 결합한 텍스트 유사도 측정 방식으로 진행된다. 따라서 기존 택배 시스템과 달리 소비자-배송원 간의 man-to-man 방식으로 양방향 선택을지원한다. 탑승 중인 승객을 물류 이동에 참여시킨다는 점에서 비용 최소화와 배송 기간 단축을모두 보장할 수 있다. 더하여 운송 측면에서도 특별한 기술을 요하지 않으므로, 일자리 입지가 축소된 노동자들에게 경제 참여 기회를 제공할 수 있다는 점에서도 의의가 있다.

The purpose of this study was to investigate the relationship between child perception of mother's rearing attitude and mother's employment status, and mother's job satisfaction. The subjects were 225 fifth graders and 70 employed mothers and 155 unemployed mothers selected from 2 primary schools located in a low income residential area in Seoul. The instruments used were a questionnaire about mother's child rearing attitude by Kim, Kyung-Hee, et al(1976) and 12 questions selected from Thomson's test of mother's satisfaction on her employment(1980) translated by Park, He-Ryung(1986). Data were analyzed by Chi-square and t-test. The resulting showed no significant statistical differences on the perception of mother rearing attitudes either as a function of mother's employment status or her job satisfaction. It was concluded that the child rearing attitude of low income mothers was not affected by the mother's employment status or job satisfaction.
The Development of the Korean Wave in Eastern Europe – The Case of Hungary

Hungary has played a significant role in disseminating the Korean Wave in Eastern Europe since the end of 2000s. With the rapidly increasing popularity of the Korean Wave in Hungary, this study analyzed its cultural impacts from two aspects: (1) how Korean cultural content had been favorably consumed in Hungary, and (2) what is the subsequent impacts of the Korean Wave in building a cultural relationships between South Korea and Hungary. This study conducted the Focus Group Discussion (FGD) with Korean Wave fans, K-pop cover dance teams, and the managers of Korean Cultural Center (Koreai Kulturális Központ) in Budapest. The discussions involved three themes: 1) cultural proximity, 2) the characteristics of K-pop, and 3) the Korean Wave fans’ participation. Findings suggested that the Korean Cultural Center in Hungary was an important institutional asset in promoting the Korean Wave in Hungary. It functioned not only as an educational institution where Hungarian citizens are exposed to diverse Korean cultures, but also as a community center for building a strong bond and social network. The Korean Wave 3.0 showed that local interests had further extended from Korean popular culture towards a broader sense of Korean culture in general. Active participations of the fans is a key factor for promoting the Korean Wave in Hungary.

Corneal endothelial cells (CEnCs) cannot be regenerated once damaged, so restoring corneal function can only be achieved through tissue engineering. In this study, biocompatible films were prepared from silk fibroin (SF) and taurine (Ta) as a carrier for the regeneration of CEnCs. Ta/SF films were prepared by mixing Ta at various concentrations (0, 0.25, 0.5, 1, and 2 mM) in a 7% SF solution to determine the effects of Ta concentrations on cornea endothelial proliferation. We observed that the 0.25 mM Ta/SF film produced the highest number of viable cells and cellular proliferation. Ta/SF film was also found to maintain cell morphology and cell functionality. Current research on graft materials for corneal regeneration focuses on maintaining transparency, adhesion, and proliferation of corneal endothelial cells. In addition to the above-mentioned advantages, the Ta/SF film in this study creates an environment similar to the native CEnCs environment by using Ta, an amino acid abundantly present in the eye tissue. Therefore, Ta/SF film may be useful as a new treatment modality and a carrier for CEnCs in cornea tissue regeneration.

본 연구는 정신지체 특수학교 직업교육의 전반적인 실태를 탐색하여 정신지체 특수학교 직업교육의 개선방향을 모색해보는데 목적이 있다. 전국 정신지체 특수학교 가운데 충청도와 전라도에 소재한 세 학교의 직업담당 부장교사와의 면담을 중심으로 정신지체 특수학교 직업교육의 전반적인 실태를 알아보았다. 이러한 면담을 통해 얻은 결과로 직업교육의 개선을 위해서는 취업현장과 연계 가능한 직업 종목의 선정과 다양화된 교육방향으로의 전환과 부족한 전문직업 담당교사 양성이 요구되며, 학생배치 시 흥미와 적성을 객관적으로 평가할 수 있는 평가도구의 개발, 학교실정을 고려한 교육과정의 재편성, 지역사회와 관련기관 및 단체의 지원이 이루어져야 한다. 직업교육이 직업생활로 지속적으로 유지되기 위해서는 직업 인식개선을 위한 부모교육과 함께 학생에게도 세밀한 추수지도가 필요하고 국가 제도적 차원에서 특정 직업 종목이 정해져야 한다. The purposes of this research were investigated to know real situations and desirable directions of vocational education on special school for the students with mental retardation. The method of this research was interview with three managing teachers in charge of vocational education. The result of this research are as follows. First, in real situations of vocational education, the contents of vocational education were insufficient situation to cultivate realistic vocational men. The items of vocational education were consist of item required simple functional skills and certifications of teacher with charge of vocational education were different by three schools. The assignment of vocational teachers and students were appropriate, because it was to decide by teacher's major and student's vocational interest. But all schools didn't consider vocational program for students with severe and profound mental retardation. Second, in desirable directions of vocational education, on qualification of vocational teacher, special education teacher should be train vocational education, and reeducation of vocational teacher will be necessary inservice training on vocation education. For desirable vocational education, positive attitude and support of the parents should be necessary in industry field and vocational curriculum for student's vocational interest should be develope in national dimension.
