Recently, as the COVID-19 has spread and prolonged worldwide, the 'Untact' society is becoming routinized, and various smart technologies are leading to the spread of the 'Ontact' culture. This is because the desire of consumers to purchase a product and use the service has increased while minimizing the direct contact. In order to quickly respond to this circumstance, the percentage of the companies which are adopting Chatbot in various fields such as orders, delivery, and inquiries is increasing and they are getting a positive result. However as the demand for building Chatbot increases dramatically, there are many confusions among the companies which want to introduce Chatbot to their system, due to the lack of professional technicians and difficulties in understanding AI technologies and how to build them effectively. I believe that in the post COVID-19 era, much more companies will adopt Chatbot, and this will intensify the problem. The purpose of this study was to derive the needs for a guide on the method of buiilding a Chatbot through considering the prior research on Chatbot and analysis of the recent surge in the use of Chatbot services related to COVID-19. There are implications to presenting 5 phases of universal Chatbot implementation methodology using the platform to the stakeholders who want to introduce Chatbot to their customer so that they can understand and build Chatbot more easily and use AI Chatbot actively in response to the POST COVID-19 era.

This study was carried out to quantify degree of contribution of harvested wood product (HWP) on mitigation of climate change by valuation of public benefits, environmentally and economically. The potential carbon dioxide emission reduction of HWP was estimated by accounting carbon storage effect and substitution effect. Based on 2014 statistics of Korea Forest Service, domestic HWPs were sorted by two categories, such as wood products produced domestically from domestic and imported roundwood. The wood products were divided into seven items; sawnwood, plywood, particle board, fiberboard (MDF), paper (including pulp), biomass (wood pellet) and other products. The carbon stock of wood products and substitution effects during manufacturing process was evaluated by items. Based on the relevant carbon emission factor and life cycle analysis, the amount of carbon dioxide emission per unit volume on HWP was quantified. The amounts of carbon stock of HWP produced from domestic and from imported roundwood were 3.8 million $tCO_{2eq}$., and 2.6 million $tCO_{2eq}$., respectively. Also, each reduction of carbon emission by substitution effect of HWP produced from domestic and imported roundwood was 3.1 million $tCO_{2eq}$. and 2.1 million $tCO_{2eq}$., respectively. The results of this study, the amount of carbon emission reduction of HWP, can be effectively used as a basic data for promotion of wood utilization to revise and establish new wood utilization promotion policy such as 'forest carbon offset scheme', and 'carbon storage labeling system of HWP'.

This study investigates the characteristics of VR stores that emerged as new fashion communication media. Two case studies on Hyundai and eBay VR Department stores were conducted along with a discussion of the function and meaning of the fashion VR store. The results showed that both stores provide novel shopping experiences; however, the two were differentiated in terms of production method and technology implementation level. Functional aspects such as providing shopping efficiency and purchasing service was insufficient in both stores. Instead, they were complementing by means of product rotation, recommendation system, voice guidance, or linkage with an online shopping mall. In experiential aspects, both stores provided a strong sense of immersion. Hyundai VR store enhanced immersion with a high resolution image of a real offline store; however, it lacked in the ability to provide multisensory stimulation such as kinetic sense or auditory stimulation. The eBay VR Department store intensified the immersion experience by providing auditory stimulation as well as visual stimulation that enhanced the speed and distance sense through the utilization of animation. However, the extent of experience was limited in terms of agency and transformation because of the low interactivity found in both store systems.

Apparel goods can be customer-oriented in the extreme and the apparel industry is one of the most customer-centered industries that should maximize customers' satisfaction. Recently, mass customization, a customer-centered system is widely discussed in the apparel industry to provide consumers with new, differentiating, distinctive, yet personalized products. The purpose of this study is to provide useful insights for apparel brands' mass customization(hereafter, MC) implementation by comparing the apparel brands' current status with consumers' expectation. One hundred apparel brands' practitioners and 116 consumers were surveyed in this research. First, we found that, on the basis of the five stages of MC presented by Pine(1993), apparel brands' MC stages were identified. Then, customers' expectation levels were examined according to the five stages. When compared the gap between the customers' expectation level and the apparel brands' implementation, consumers' expectation of MC was significantly higher than the implementation level by apparel brands for the stage 2(customized products creation), the stage 5(modular production). Second, by conducting a factor analysis with the scales measuring the MC activities of the five stages, apparel brands' current MC strategies could be classified as 'mass customized strategy', 'quick response strategy', 'MOT(moment of truth) customized strategy', and 'individualized service strategy.' Apparel brands showed significant differences in mass customized strategy, quickresponse strategy, and MOT customized strategy according to their product characteristics. Finally, consumers' expectation level of MC strategies was significantly different by their characteristics such as shopping orientation.

Objectives: The purpose of this study was to classify determinants of cost increases into two categories, negotiable factors and non-negotiable factors, in order to identify the determinants of health care expenditure increases and to clarify the contribution of associated factors selected based on a literature review. Methods: The data in this analysis was from the statistical yearbooks of National Health Insurance Service, the Economic Index from Statistics Korea and regional statistical yearbooks. The unit of analysis was the annual growth rate of variables of 16 cities and provinces from 2003 to 2010. First, multiple regression was used to identify the determinants of health care expenditures. We then used hierarchical multiple regression to calculate the contribution of associated factors. The changes of coefficients ($R^2$) of predictors, which were entered into this analysis step by step based on the empirical evidence of the investigator could explain the contribution of predictors to increased medical cost. Results: Health spending was mainly associated with the proportion of the elderly population, but the Medicare Economic Index (MEI) showed an inverse association. The contribution of predictors was as follows: the proportion of elderly in the population (22.4%), gross domestic product (GDP) per capita (4.5%), MEI (-12%), and other predictors (less than 1%). Conclusions: As Baby Boomers enter retirement, an increasing proportion of the population aged 65 and over and the GDP will continue to increase, thus accelerating the inflation of health care expenditures and precipitating a crisis in the health insurance system. Policy makers should consider providing comprehensive health services by an accountable care organization to achieve cost savings while ensuring high-quality care.

인류는 오랫동안 인간을 대체할 수 있는 자동화된 노동력 또는 지능체를 만들기 위해 노력해 왔다. Turing(1950)이 인간과 같이 생각할 수 있고 대화를 할 수 있는 기계 혹은 시스템의 개발을 제안한 이래로 인공지능이라는 학문분야가 발전하고 있다. 최근 들어 알파고의 등장과 제4차 산업혁명에 대한 관심이 높아지면서, 핵심 기술로서 인공지능 기술에 대한 연구가 대학교 연구실뿐만 아니라 기업에서도 활발하게 이루어지고 있다. 인공지능 기술이 우리의 생활에 깊숙이 파고들면서, 과거에 비하여 사람들의 생활은 많이 편해지고 윤택해진 것은 사실이지만, 다른 한편으로는 여러 가지 부정적인 영향을 미칠 수 있을 것이다. 기술이 우리의 생활과 사회에 긍정적인 영향만을 주는 것이 아니기 때문에, 기술로 인한 사회의 변화에 대해서 생각해 보고 이에 대한 기술적, 사회적, 정책적 대응을 준비하는 것이 필요하다. 본 논문에서는 다양한 선행연구들의 분석을 통해 AI의 역사와 개념에 대해서 살펴보고, AI기반의 지능형 제품과 지능형 서비스가 일으키는 사회의 변화를 일상생활과 업무환경의 변화 차원에서 분석하여 인공지능으로부터 야기되는 사회의 변화와 정책적 이슈에 대해서 고찰해 보고자 한다.
