국내 배출권 시장에서는 시장안정화 조치 발동에도 불구하고 배출권 가격의 불확실성 문제가 지속적으로 대두되고 있다. 그리고 2021년 10월 정부가 발표한 2030 감축목표 상향안을 고려해볼 때 배출권 가격의 불확실성 완화를 위한 실질적인 대안 마련의 필요성이 높아지고 있다. 본 연구는 배출권 시장의 가격 불확실성 완화 수단인 가격상하한제가 배출량과 감축비용에 미치는 정량적인 영향을 살펴본다. 분석을 위한 주요 시나리오는 탄소세, 배출권거래제, 가격상하한제하 배출권거래제 3가지로 구분되며, 배출량 불확실성을 반영하기 위해 몬테카를로 시뮬레이션을 기반으로 비교 분석하였다. 연구 결과는 다음과 같다: 1) 상하한제 도입 시에는 다른 시나리오 대비 현저히 낮은 감축비용으로 배출목표를 달성할 수 있다. 상향된 감축목표에서는 0.1%의 초과배출이 발생할 수 있으나 상하한 간격이 넓은 경우 안정적인 목표달성이 가능하다. 2) 이월을 제한할수록 감축비용은 상승한다. 이는 이월 제한 정책이 기간 간 효율성을 저해하여 비용효과적인 감축을 어렵게 만들기 때문이다. 3) 상하한제하에서 정부의 배출권 순구매량이 발생해도 순수입은 양이 될 수 있다. 정부는 배출권을 상한가에서 판매하고 하한가에서 구매하기 때문이다.

주요 상대국들과 무역에서 환율과 노동숙련도의 구성이 베트남의 무역수지에 미치는 역할 본 연구는 베트남이 주요 20개국과 무역을 할 때 환율과 노동숙련도의 구성이 무역수지에 미치는 영향을 조사하였다. 2000년부터 2016년까지의 균형패널자료 (balanced panel data)를 활용해서, 저자는 베트남의 총 무역수지와 노동기술의 정교화로 인한 무역수지를 분석하였다. 본 연구의 주요 세가지 결론은 아래와 같다: 첫째, 환율은 베트남의 무역수지에 긍정적인 영향을 미치지만 그 계수 (coefficient) 가 작아 그 효과는 제한적이라는 것을 알 수 있었다. 둘째 베트남 화폐 (VND(Vietnamese Dong))의 가치가 떨어질 경우 베트남의 고숙련노동상품과 중숙련사무직 노동생산품의 무역수지는 악화된다. 셋째, 고숙련상품과 중숙련 사무직 생산 상품의 노동 기술 숙련도를 높이고 비가격경쟁력을 향상시킴으로서 베트남의 총 무역수지를 개선할 수 있으며, 반면에 저숙련노동 및 중숙련 블루칼라 노동생산 상품은 더 이상 베트남의 총 무역수지개선에 도움이 되지 않을 것이다.

Objectives: The purpose of this study is to examine the effect of the raise of cigarette prices by KRW 2,000 at the beginning of 2015 on the change in smoking behavior among male office workers, and to analyze the correlation of various factors including their work behaviors and socio-economic factors with their smoking rate. Methods: In this research, a follow-up observation panel was constituted with 420 smokers as targets from among male office workers at a bank located in Daegu, South Korea. A cross-analysis and ANOVA analysis were carried out in order to examine whether changes in smoking status, amount of smoking, stop-smoking motivation, and reasons for smoking cessation failure after the passage of time since the cigarette price hike were statistically significant. The level of statistical significance was P < 0.05. Results: After the cigarette price hike, among the 420 smokers who were the target of the panel the rate of smoking cessation declined at the time-point of the survey to 15.5%, 12.4%, 8.5%, and 5.7% after one month, three months, six months, and 12 months, respectively. As a result of a follow-up observation of 65 smokers who stopped smoking immediately after the price hike, the actual non-smoking rate declined to 15.5%, 8.3%, 4.4%, and 3.1% after one month, three months, six months, and 12 months, respectively. One (1) year after the cigarette price hike, the non-smoking rate among the 420 smokers reached as low as 3.1% (13 persons). The most important reason for the failure of the attempts to quit smoking was stress for more than 60% of the smokers who attempted to stop. Conclusions: It seems that a powerful anti-smoking policy by the state targeting the nation's workers is necessary. For companies, mediation for workers' job stress can become a strategy for the success of non-smoking attempts. The government seems to require a practical policy to reduce the smoking rate by actively carrying out social, economic, and scientific research to come up with a reduction method for the cigarette hazard, an effective price hike policy, and other non-price policies.

Plants are the basis for sustainable green growth, and the value of existence and importance of trees including landscape Plants can't be emphasized enough. Therefore, they are precious living things thriving in all sorts of public services, and continuous civil complaints for justifiable compensation of landscape Plants are filed. First, the standard formula of planting intervals according to production target specifications is calculated using root-collar caliper and diameter at breast height, and apply (1) standard medium sized trees which have not yet reached commercialization [deciduous tree production goal (R(B) less than 6cm]= (target standard)= [target standard $R(cm){\times}15{\times}0.7$]. (2) In case of commercialization(R6~R10)= [target standard $R(cm){\times}15{\pm}5%$], (3) In case of more than R12= [target standard $R(cm){\times}15{\times}130%$] shall be applied. In case of using diameter at breast height (4) In case of commercialization(B6~B10)= [target standard $B(cm){\times}20{\times}15{\pm}5%$], (5) In case of more than B12= [target standard $B(cm){\times}20{\times}130%$] shall be applied. Second, appraisal methods based on tree classification of compensation for loss are classified according to planted locations. (1) landscape trees within a house=[price of arrival at the site+planting cost], (2) landscape trees in places such as arboretum=[management technology of tress + relocation expenses considering scarcity of the trees (3) landscape trees in a place of loads= [landscape tree production cost + work out added price. In case of producted landscape threes (4) landscape trees ready to be commercialized as sales loss.

The purpose of the study was to provide the actual data for designing adaptive dresses for the disabled elderly. In order to get the data, we had 3 parts of the procedure as follows ; 1. The survey of 205 nursing-care providers who take care of the disabled elderly in 1999. 2. Measuring 10 measurements of 80 disabled men and women each, 160 samples. 3. On the basis of data above, developing the adaptive dresses and doing the wearing-tests of those. The results are as follows ; 1. The most popular style for the disabled elderly in nursing facilities was non-collar pajama's. Specially, pajama style was needed for the disabled elderly being sick in bed, one-piece style was required for the disabled eldery with dementia. And the most desirable fabric function was a physiological comfortability. The most proper price required was about 20,000 won. 2. As Korean apparel industry use K.S. sizing system, we decided to use the same measurement to categorize the samples, bust and height. And according to the frequency in the size chart, we suggested the production size for the disabled eldery men and women. 3. After developing these adaptive dresses, the results of wearing-tests showed two kinds of problems. One was that of the sleeve length ; Actually, for the disabled elderly, the longer than the production size is the better for them. The other problem was revealed from subsidiay materials, fasteners.
