We present the pricing and hedging method for options with general payoffs in the presence of transaction costs. The convexity of the payoff function-gamma of the options- is an important issue under transaction costs. When the payoff function is convex, Leland-style pricing and hedging method still works. However, if the payoff function is of general form, additional assumptions on the size of transaction costs or of the hedging interval are needed. We do not assume that the payoff is convex as in Leland 〔11〕 and the value of the Leland number is less (bigger) than 1 as in Hoggard et al. 〔10〕, Avellaneda and Paras 〔1〕. We focus on generally recognized asymmetry between the option sellers and buyers. We decompose an option with general payoff into difference of two options each of which has a convex payoff. This method is consistent with a scheme of separating out the seller's and buyer's position of an option. In this paper, we first present a simple linear valuation method of general payoff options, and also propose in the last section more efficient hedging scheme which costs less to hedge options.

In the COVID-19 era, it was implemented to be used as a basic material for setting the direction of learning support and student guidance for university institutions and professors who are experiencing confusion. The purpose of this study is to compare the actual status of daily-routines of COVID-19 period, general semester period, and vacation period, and to examine whether there is a difference between the period of general semester and COVID-19 period, and whether there is a difference in daily use of COVID-19 period depending on grade. For this reason, a questionnaire survey was conducted from April 23 to 29, 2020, targeting students of University A, which is a small-scale technical centered university in the region, and 754 students answered. As a result of the study, first of all, when we looked at the trends in the use of daily-routines by period of general semester, vacation period, and COVID-19 period, the trends of the general semester period and COVID-19 period were similar in the areas of learning and self-development. Second, there were statistically significant differences in sleep, relaxation, learning and other areas between the period of the general semester and the duration of COVID-19. Third, there were statistically significant differences over grade in relaxation, learning, development, and other areas.

대학의 교양교과 주제가 다양한 영역으로 분화되고 복합적인 주제로 융합되면서 점차 교양교육의 주제를 파악하는 것이 어려워지고 있다. 이 연구의 목표는 A 대학의 교양교육과정으로 개설되어 있는 교과목의 주제적 영역을 계량정보학적으로 분석하여 시각화하는 것이다. 분석을 위하여 수집된 계획서는 총 214개이며 분석에 적용된 요소는 교과목명, 교과개요, 목표, 주별 수업계획이다. 분석 대상에서 추출된 주제어는 모두 278종이며 총 8개의 주제 클러스터로 군집화 되었다. 주제 클러스터간 관계를 네트워크기법으로 분석한 결과 개인적 영역, 사회적 영역으로 나뉘어지는 것으로 나타났다. 개인적 영역은 다시 14개 하위 주제 클러스터로, 사회적 영역은 11개 하위 주제 클러스터로 분류되었다. 개인적 영역에서는 '언어', '과학', '인성'이 주요 주제 클러스터로 파악되었고 사회적 영역에서는 '다문화' 주제 클러스터가 4개의 다른 주제 클러스터와 다각적인 관계를 맺고 있는 것으로 분석되었다. 주제 네트워크로 교양교과목의 주제 영역을 분석한 방법은 교양교육을 강화하고 개선하거나 대학도서관이 교양교육을 위한 장서개발을 하는데 필요한 기초자료를 생산하는 목적으로 활용될 수 있을 것이다.

Objectives : The purpose of this study is to compare the efficacy of fire needling therapy and general acupuncture for the patient with lumbar herniated intervertebral disc. Methods : We observed 20 lumbar herniated intervertebral disc patients from March, 2014 to October, 2015. This study was randomized and assessor blinded. The patients were divided into two groups: one group(group A) was treated by general acupuncture only, and the other group(group B) was treated by fire needling therapy and general acupuncture. We evaluated the treatment effect experienced by each group using the visual analogue scale(VAS) and Oswestry disability index(ODI). Results : 1. In group A, VAS and ODI from before treatment to treatment 4, 8, 12, 16 were significantly improved in statistics. 2. In group B, VAS from before treatment to treatment 4, 8, 12, 16 was significantly improved, but ODI was significantly improved in statistics only from before treatment to treatment 12, not in treatment 4, 8, 16. 3. As a result of comparisons between group A and B, there were no statistical significance in VAS and ODI. Conclusions : This study was not able to determine statistical significance between the group treated by general acupuncture only and the group treated by fire needling therapy and general acupuncture, so further studies are required in the future.

Objective: The present study was conducted to evaluate the viability of germ cells from the adult and fetal ovarian tissues after vitrification followed by xenografting. Method: The human adult ovarian tissues were obtained from 33 years old patient, and the fetal ovarian tissues were obtained from 22 weeks and 25 weeks in gestation. Ovarian tissues were cryopreserved by vitrification with 5.5 M ethylene glycol (EG 5.5) and 1.0 M sucrose as cryoprotectants. Adult and fetal ovarian tissues were pre-equilibrated with EG 5.5 at room temperature for 10 and 5 minutes, respectively and plunged into liquid nitrogen immediately. Frozen-thawed tissues were xenografted into NOD-SCID mice to evaluate the viability and capacity for further growth of the primordial follicles. Grafts were recovered from the recipients 4 weeks after transplantation and histological analysis was accomplished. Result and Conclusion: Grafts recovered 4 weeks after transplantation contained less number of oocytes and primordial follicles compared to that of the fresh tissues. Survived follicles were mainly primordial and intermediary with larger diameter and more granulosa cells. It is confirmed that 1) the ovarian tissues were healthy and the germ cells were survived after vitrification, and 2) the survived fetal primordial follicles after vitrification resumed the growth in the xenografts.
