For the purpose of breeding a high-yield superior variety of Korean raisin tree (Hovenia dulcis var. koreana Nakai), whose value as an edible and medicinal resource is increasing, tree candidates for superior individuals were selected from its 11 habitats in Korea from 1996 to 1998. A clone bank preserve was created in 1998 with 70 clones proliferated by grafting; the fruition traits (e.g., the number of fructified laterals, the average number of bunches per fructified lateral, the average number of bunches per fruiting lateral, the fruitpetiole weight per individual, and the yield per individual) of 47 clones that had bloomed and borne fruit were investigated and analyzed in 2002; five upper-ranking clones whose yield per individual exhibited a 261% improvement against the total average were picked in 2005; and three clones, including 'Poong-Sung 1', that showed a difference in their fruit petiole ripening stage, were finally selected in 2007 as high-yield new cultivars of Korean raisin tree.

The paper presents the results of a study on the determinants of customer satisfaction for a retail bank using the data of 2009 NCSI(National Customer Satisfaction Index, KPC). In doing so, it uses a revised version of the traditional analyses based on derived measures of attribute importance. The need for a revised methodology is prompted by the insights of the two- and three-factor theories of customer satisfaction, such as Kano's framework. Indeed, the evidence from 1635 customers of 6 Korean banks confirms an asymmetric relationship between attribute performances and overall customer satisfaction. The results from both a traditional and our revised approach are compared. While this approach can be applied across different industries, it should not be assumed that the numerical results presented in the paper apply to contexts with substantially different underlying characteristics. General trends and practical implications for banking services are reported in the conclusions.

The purpose of this paper is to investigate the impact of total factor productivity (TFP), institutional quality, and interactive variable between them on economic growth in 13 low-middle income countries in Asia for the period 2000-2018. The paper uses the difference Generalized Method of Moments (GMM) to explore the dataset provided by the World Bank. The empirical results show that TFP and the interactive variable positively impact on the economic growth, while the institutional determinants have a negative influence. The negative effect is explained by the weak institutions in these low-middle income countries. The findings of the study suggest two points. First, the government should continue to improve TFP, which is associated with the application of technical advances, technological innovations, improvement of management methods, and skilled workers. Second, far more important, is that the authorities should pay special attention to implement institutional reform and strengthen the governance in the future. The successful experiences from Japan, Korea and Singapore will help other governments in Asian low-middle income countries to build developmental state. Probably, the developmental state actively interfere in the market to promote and realize the development goals. By doing so, these economies might overcome the so-called "middle-income trap".

The purpose of this study is to identify major drivers of Myanmar's long-term economic growth and draw implications to implement development policies. This study investigated Myanmar, as the country is the most recently opened economy in Southeast Asia. This study conducted simulation analysis based on scenarios by applying World Bank's Long-Term Growth Model, Penn World Table 9.1, and World Development Indicator data. This study makes extensive use of LTGM and the LTGM-TFP extension to improve the validity of models for data calibration. This study confirms the validity of the model with data calibration and specifies scenarios for simulation analyses by setting the growth trajectory of Vietnam due to common geographical, political, and economic conditions. Main findings include that Myanmar's economic growth rate will continue to fall below 3% in 2040 without proper improvement of growth drivers. The results of this study also provide that total factor productivity growth and female labor participation are key factors for Myanmar's long-term economic growth. This study advises policymakers in Myanmar to strengthen human capital, which is crucial for total factor productivity growth in Myanmar's context and directly affects economic growth. Further, labor market policies to promote female labor participation is important to sustain economic growth.

Thailand had issued a national strategic development master plan with issues related to water resources and water security in the entire water management. Water resources are an important factor of living and development of the country's socio-economy to be stable, prosperous and sustainable. Therefore, water management in both multidimensional and multi-sectoral systems is important and will supports socio-economic and environmental development. The direction of national development in accordance with the national strategic framework for 20 years that requires the country to level up security level in terms of water, energy and food. To response to the proposed goals, there is a subplan to increase water productivity of the entire water system for economical development use by evaluating use value and to create more value added from water use to meet international standard level. This study aims to evaluate the water productivity of Thailand in each basin and all sectors such as agricultural sector, service and industrial sectors by using the water use data from water account analysis and GDP data from NESDB during the past 10 years (1996-2015). The comparison of water productivity with other countries will also be conducted and in addition, the measures to improve water productivity in next 20 years will be explored to response to the National Strategic Master Plan goals. Water productivity is defined as output per unit of water depleted. The simplest way to compare water productivity across different enterprises is in monetary terms. World Bank presents water productivity as an indication of the efficiency by which each country uses its water resources. There are two data sets used for water productivity analyses, i.e., the first is water use data at end users and the second is Gross Domestic Product. The water use at end users are estimated by water account method based on the System of Environmental-Economic Accounting for Water (SEEA-Water) concept of United Nations. The water account shows the analyses of the water balance between the use and supply of each water resource in physical terms. The water supply and use linkage in the water account analyses separated into each phases, i.e., water sources, water managers, water service providers, water user at end user under water regulators of all kinds of water use activities such as household, industrial, agricultural, tourism, hydropower, and ecological conservation uses. The Gross Domestic Product (GDP), a well- known measuring method of the national economic growth is not actually a comprehensive approach to describe all aspects of national economic status, since GDP does not take into account the costs of the negative impacts to natural resources that result from the overexploitation of development projects, however, at present, integrating the environment with the economy of a country to measure its economic growth with GDP is acceptable worldwide. The study results will show the water use at each basin, use types at end users, water productivity in each sector from 1996-2015 compared with other countries, Besides the productivity improvement measures will be explored and proposed for the National Strategic Master Plan.

This study was conducted to determine the optimal collecting time and methods of utilization of forest topsoil as a seed-bank source for revegetation materials of slopes. From April to November of 1998, nursery seedbeds in the greenhouse of Seoul National University were seeded with mixtures of forest topsoil and seeds. The nursery seedbeds were treated to evaluate the effect of depths of forest topsoil and seeding amounts. Seasonal experiments with $3{\times}3$ factorial design were conducted in April, June and August. More than 40 seedlings/$m^2$ were observed as the naturally-emerged species in the plot, treated with the top-layer forest soil within the depth of 10cm. However, it was found, as seeding more seeds, the number of appearance of the naturally-emerged species reduced because of the heavy competition between the seeded and the naturally-emerged. According to the results of this research, it is recommended that seeding amount should be no more than 1,000 seeds/$m^2$ to avoid the severe competition. Also it was observed that the forest topsoil collected in spring(April) is better than that collected in summer. The more species of the naturally-emerged were found in the forest topsoil collected in spring. Forest-topsoil-mixed-materials as a seed-bank source could significantly increase the plant diversity and productivity. Effective use of forest topsoil as a seed-bank source may become a valuable tool in future restoration of disturbed slopes for promoting plant community diversity and recycling of spoiled-soils from the slopes.

본 연구는 1981년부터 2019년까지 한국의 생산가능인구 1인당 실질 GDP 추세성장률을 추정하기 위해 추세성장률이 임의보행을 따르는 비관측요인모형을 사용한다. 추정 결과, 추세성장률은 외환위기를 극복하던 시기인 2000년 전후를 제외하고 1980년대 후반부터 2010년대 초반까지 지속해서 하락하였다. 추세성장회계를 통해 추세성장률 하락요인을 분석한 결과, 지속적인 추세성장률 하락은 노동생산성 둔화와 관련이 깊은 것으로 나타났다. 구체적으로 살펴보면, 1988년부터 1998년까지의 추세성장률 1차 하락기는 외환위기 이전부터 둔화되기 시작한 노동증강 총요소생산성에 가장 큰 영향을 받았다. 이러한 결과는 외환위기로 추세성장률이 하락했다는 가설과는 배치되는 것이다. 한편 부진한 투자는 2002년부터 2012년까지의 2차 하락기의 중요한 배경인 것으로 나타났다.

본 연구는 2006~2014년 통계청의 기업활동조사 자료를 이용하여 우리나라 제조업 기업의 수출중단 결정요인을 실증적으로 분석하였다. 이를 위해 생존분석 기법인 Complementary Log-Log 모형을 통해 우리나라 제조업 수출기업의 수출중단 가능성에 기업 및 산업 특성과 거시경제 변수들이 미치는 영향을 추정하였다. 분석결과, 기업 특성인 고용규모, 자본집약도, 무형자산 소유여부, 외국인 소유여부와 산업 특성인 신규기업의 고용대체율 등이 수출중단 가능성에 유의한 영향을 미치며, 거시변수 중 세계수요 증가, 국내수요 감소가 수출기업의 수출중단 가능성을 유의하게 감소시키는 반면, 환율의 영향은 유의하지 않은 것으로 추정되었다. 또한, 시장금리가 상승하면 금융시장 자금조달여건이 불리해짐에 따라 수출기업의 수출중단 가능성이 커지며, 부채비율이 높은 기업이 이러한 금융여건의 영향을 더욱 크게 받는 것으로 나타났다. 한편, 수출 주력산업인 경우 생산성이 높을수록 수출기업의 수출 중단 가능성이 감소하는 것으로 분석되었다. 본 연구결과는 기업 및 산업 특성과 거시 실물 변수 및 금융여건이 수출중단에 복합적으로 영향을 미치고 있음을 보여준다. 또한, 수출 주력산업 내 기업들의 생산성 제고와 기업의 재무건전성 향상이 수출기업들의 수출중단 가능성을 감소시키는 방향으로 작용할 수 있음을 시사한다.

본고의 주요 목적은 OECD 국가들과의 비교를 통해 우리나라 노동시장의 유연성 및 안정성의 수준을 평가하는 데 있다. OECD 고용보호법제 지수로 평가한 우리나라 노동시장의 유연성은 상용직 해고의 경우 여타 국가들과 대체로 비슷한 수준을 보였으며, 임시직 고용은 임시직의 비중 등 실효적 지표들까지 감안할 때 비교적 유연한 것으로 나타났다. 안정성의 경우에는 직장안정성, 소득안정성 및 결합안정성의 수준 모두 OECD 평균치를 큰 폭으로 하회하였다. 추가적으로 OECD 국가들을 대상으로 패널분석을 수행한 결과, 유연성 측면에서는 상용직 해고 규제가 느슨할수록, 임시직 고용 규제는 엄격할수록 노동생산성이 향상되는 것으로 추정되었다.
