Background: It is necessary to verify the resilience of the newly improved Kneipp psychotherapy. Purpose: This study assesses whether Kneipp Lebensordnung psychotherapy; KnLP program improves resilience. Methods: The KnLP program, including salutogenesis, logotherapy, meditation, and resilience training, is reorganized in consideration of Korean culture and sentiments. It was conducted 4 times for 25 adults (once a week, 3 hours a time), and data, KRQ-53 (Korean Resilience Quotient-53) measured intervention, before, and after was compared and analyzed. Results: The data for 9 adults were selected to draw reliable analysis, and it concluded that participants' KRQ-53 mean score increased by 14.66 from 191.56 to 206.22 during and after the program. The score increase by factor in resilience training is 5.89 points for self-regulation skills, 4.89 points for in interpersonal skills, and 3.89 points for positive capacity. Conclusions: KnL program improves participants' resilience skill (p<.05), and especially in self-regulation skill. Subsequent studies with more participants are required to achieve statistically significant and generalized results in the future.

The country with a relative abundance of human capital conducts relatively more R&D in the steady state than its partner. This country acquires the know-how to produce a relatively wider range of innovative goods. High technology comprises a large share of the national economy in the human-capital rich country and real output growth is faster. This prediction would seem to accord weakly with empirical observation of Korean economy.

본고에서는 우리나라의 수출수요함수(輸出需要函數) 추정(推定)에 있어서 1) 통상적으로 많이 사용되고 있는 수출단가지수(輸出單價指數) 대신 수출물가지수(輸出物價指數)를 이용하고, 2) 공적분(共積分)벡터의 추정에 있어서 Engle and Granger(EG)의 정태적(靜態的) OLS 대신 효율적(效率的) 추정법(推定法)(efficient estimator)을 이용하여 수출(輸出)의 소득(所得) 및 가격탄성치(價格彈性値)를 추정(推定)하고자 하였다. 추정결과(推定結果) 소득탄성치(所得彈性値)는 어느 경우에나 큰 차이가 없었으나 가격탄성치(價格彈性値)에 있어서는 큰 차이가 발견되었다. 즉 수출단가(輸出單價)를 EG방법(方法)으로 추정(推定)한 경우에는 비탄력적(非彈力的)인 것으로, 수출물가(輸出物價)를 이용한 경우에는 단위탄력성(單位彈力性)을 갖는 것으로, 그리고 효율적(效率的) 추정법(推定法)을 이용한 경우에는 매우 탄력적(彈力的)인 것으로 판명되었다. 또 EG 방법을 이용한 경우에는 공적분관계(共積分關係)의 존재가 부정되었으나 효율적(效率的) 추정법(推定法)을 이용한 경우에는 유의(有意)한 공적분관계(共積分關係)가 존재하는 것으로 나타났다.

This paper attempts to estimate the energy price elasticity of per capita $CO_2$ emissions, which helps to understand the influence of recent energy price increase on the natural reduction of $CO_2$ emissions. For this purpose, this study researched panel data of twenty-nine OECD countries from 1978 to 2009 and adopted estimation models for testing the environmental Kuznets hypothesis. Estimation results show that the 1% increase of energy price index will cause a statistically significant decrease of per capita $CO_2$ emissions by 0.26 ~ 0.31%, which is substantial enough for policy consideration. Also Kuznet curves in estimation models were identifed, the turning points of income lie between 22.2~48.5 thousand US dollars, depending on model specifications.

The rheological properties and food functionality of the novel sugar derivatives, fructo-oligosaccharide, high maltose syrup(HMS), maltitol and sorbitol were examined and compared to those of sucrose. All samples tested showed Newtonian fluid property at the concentration range of 10% to the original concentrated products containing $69{\sim}81%w/w$ solid. HMS showed the highest viscosity. The viscosity increased(r=0.8038) as the average molecular weight of sugar derivatives were increased. The viscosity increased exponentially as the concentration increased, and sugar alcohols had lower value of the exponent compared to HMS and fructo-oligosaccharide. The viscosity of sugar derivatives solutions decreased by the increasing temperature following the Arrhenius equation. The flow activation energies of sorbitol and HMS were higer than that of sucrose. Substitution of sucrose with fructo-oligosaccharide in apple jam processing did not change the textural characteristics, but in redbean jelly(yanggaeng) it reduced the hardness, adhesiveness, springiness and cohesiveness. When sucrose was 100% replaced by HMS, the texture of apple jam and redbean jelly was not changed, but by mixing sucrose and HMS 1 : 1 ratio, the hardness decreased substantially The sugar alcohols reduced the hardness, adhesiveness, springiness of apple jam and redbean jelly significantly. Addition of fructo-oligosaccharide and HMS to sucrose did not influence the solidifying rate of candy, but sorbitol, even at 10% addition, retarded the candy moulding.

This study examined the relationship of resilience, academic stress and academic achievement of nursing students. Data were collected through self reported structured questionnaire in 197 nursing students from September 26 to October 12, 2019. Data were analyzed using SPSS/WIN 23.0. As a result this study, resilience was negatively correlated with academic stress(r=-.46, p<.001). while resilience was positively correlated with academic achievement(r=.48, p<.001). As a result regression analysis, social support, structural style, and positivity among the sub-variables of resilience explained 28.4%(F=24.80, p<.001) of the academic stress in nursing students. Relational, and self confidence explained 22.7%(F=27.80, p<.001) of the academic achievement Therefore, it is necessary to develop interventions that can enhance social support structural style, positivity, relational, and self confidence to manage the academic stress and to improve academic achievement of nursing students.

Discussions for water resources vulnerability and index development with sustainable concept are actively being made in recent years. Based on such index, water resources vulnerability of present and future is determined and diagnosed. This study calculated the water resources vulnerability rankings by 152 nations, using indicator related to water resources assessment that can be obtained from World Bank, VRI (Vulnerability Resilience Indicator), ESI (Environmental Sustainability Index). In order to quantitatively assess of water resources vulnerability based on this indicator, TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) technique was applied to index water vulnerability and to determine the rankings by nations. As a results, South Korea was ranked as the 88th among the 152 nations including Korea. Among the continents, Oceania was the least vulnerable and Afirica was the most vulnerable in continents. WUnited State, Japan, Korea and China were vulnerable in order among the major countries. Therefore, water resources vulnerability rankings by nations in this study helps us to better understand the situation of South Korea and provide the data for water resources planning and measure.

외환(外換) 및 자본자유화(資本自由化)의 진전에 따라 환율(換率)의 변동폭이 커지면서 환율(換率)이 국제수지(國際收支)에 미치는 영향에 대한 관심이 높아지고 있다. 환율(換率)이 국제수지(國際收支)에 미치는 효과는 일차적으로 우리나라 수출입함수(輸出入函數)의 가격탄력성(價格彈力性)에 의해 결정되므로 정확한 탄성치(彈性値)를 추정하는 일은 이론적으로나 정책적으로 매우 중요한 의미를 갖는다. 본고에서는 우리나라 수입함수(輸入函數)의 소득(所得) 및 가격탄성치(價格彈性値) 추정에 있어서 사용 가능한 두가지의 가격지수(價格指數), 즉 수입단가(輸入單價)와 수입물가(輸入物價) 중 어느 것을 사용하는 것이 바람직한 것인지를 살펴보고 이중 이론적으로 우월한 지수를 이용하여 수입함수(輸入函數)의 소득(所得) 및 가격탄성치(價格彈性値)를 추정하고자 하였다. 분석으로부터 얻는 중요한 결론(結論)은, 우리나라의 경우 수입함수(輸入函數)의 분석에 있어서 수입단가(輸入單價)보다는 수입물가(輸入物價)를 이용하는 것이 더 적합하리라는 점이다. 이는 또한 우리나라 실질(實質)GNP의 추계에 있어서 현재의 수입단가(輸入單價) 이용방식에서 수입물가(輸入物價) 이용방식으로 편제방법을 바꾸는 것이 바람직하다는 것을 의미한다. 이같은 결론은 이론적, 실증적인 변에서 아래와 같은 네가지 이유에 근거한다. 먼저 이론적인 면에서는 첫째, 수입단가(輸入單價)가 물가지수(物價指數)로서 갖추어야 할 통계적 일관성을 갖추지 못하고 있다는 점을 지적할 수 있다. 즉 수입단가(輸入單價)는 어느 일정 규격조건(規格條件)의 상품가격(商品價格)을 일관성 있게 추적하는 것이 아니므로 잡다한 품질규격의 평균가격(平均價格)으로 나타날 가능성이 높으며 이러한 변에서 가격변화(價格變化)를 정확히 반영하지 못한다. 둘째, 수입단가지수(輸入單價指數)는 가격변화(價格變化)가 전혀 없을 때에도 총수입(總輸入)의 품목별 구성(構成)이 바뀌면 변동하는 속성을 지니고 있어 가격변동(價格變動) 상황(狀況)을 오도할 가능성을 지니고 있다. 다음으로 실증적인 면에서는 첫째, 수입단가(輸入單價)를 이용한 수입함수(輸入函數)에서는 가격변수(價格變數)의 계수(係數)가 이론상 기대되는 것과는 반대되는 부호를 가짐으로써 수입함수(輸入函數))로서의 기본적인 요건을 만족시키지 못하는 것으로 나타나고 있다. 둘째, 단가지수(單價指數)를 이용한 경우 소득(所得)과 상대가격(相對價格)을 회귀변수로 하는 수입함수(輸入函數)에서 장기안정적인 균충관계(均衝關係)가 존재하지 않은 것으로 판명되었다. 반면 수입물가(輸入物價)를 이용한 수입함수(輸入函數)에서는 각 변수의 계수(係數)가 이론적 기대치에 부합하였으며 장기안정적인 균충관계(均衝關係)가 성립하는 것으로 나타나고 있다. 한편 미국에서는 수출입단가지수(輸出入單價指數)의 문제점에 대한 오랜 연구 결과, 1989년부터 단가지수(單價指數)의 편제를 아예 중단하는 조치를 취한 바 있으며, GNP추계에 있어서도 종래의 수출입단가(輸出入單價) 대신 수출입물가(輸出入物價)를 이용하는 방식으로 그 편제방법을 변경한 바 있다.

This paper analyzes the firms' optimization behavior in response to rising demand for non-priced renewable energy in the manufacturing industries by using an input distance function. The annual estimates of the shadow price of renewable energy is derived and the trend of its shadow price over time is analyzed. The degree of substitution of renewable energy for fossil-fuels is examined. The input-based Malmquist productivity index, defined as a composite of the technical efficiency and technical change measures, is measured. The contribution of renewable energy input growth to the Malmquist index is analyzed. Empirical results indicate that the shadow price of renewable energy declined at an average annual rate of 17% over the period 1992-2012. Substitutability between renewable energy and fossil-fuels was limited. On average, a 1% increase in renewable energy would decrease Malmquist index by 0.04% per year.

In this paper, we test for allocative efficiency of productive inputs including electricity and measure the divergence between the actual and optimal level of electricity for the chemical products, which is a relatively highly electricity-intensive sector in Korean manufacturing industries, by estimating a shadow cost function. Supposing cost minimization subject to market prices was achieved, we derive the price elasticities of demand for each input and simulate the impact of a 10% increase in power rate on its demand and supply price by estimating jointly a cost function with an inverse supply relation. The null hypothesis of allocative efficiency of inputs is rejected over the period 1982-2006. On average, electricity is used more than optimal level by 98% per year. The demand for electricity decreases by 11.4%, and supply price, on average, falls by 0.08%, other things being equal.
