Korea has exerted her efforts to assimilate nuclear power technology, and reportedly localized 95 percent of nuclear power technology by 1995. This paper investigates the evolution of nuclear power program in Korea to exploit the development process of the nuclear power industry and key factors for the technological localization of nuclear power plant. In developing countries, an imitative catching-up process can be shown as a course for developing the absorptive capacity of foreign technology, which depends on prior knowledge base and the intensity of effort. The process of technological learning consists of five stages including preparation, implementation of foreign technology, acquisition of peripheral technology, acquisition of core technology, and improvement f foreign technology. Moreover, this paper discusses six essential factors that have influenced the successful achievement of technological localization of nuclear power plants in Korea. They include the role and strategies of the government, the leading role of utility firm, the development and cooperation of the related organizations, the development of human resources and their efforts, market conditions and the assistance of foreign donors, and social conditions. Finally, this paper discusses about implications offered by the Korean experience for other developing countries.

We performed an analysis of the effect of postharvest treatment of rhizomes of Aconitum septentrionale Koelle with the biological preparation of Bacispecin based on a cytokinin producing strain of Paenibacillus ehimensis IB-739 on the content of alkaloid lappaconitine in rhizomes. The total alkaloid content was assayed based on exhaustive extraction method. The lappaconitine content was measured by HPLC. The efficiency of the preparation was dependant on either the concentration or intensity of the growth processes in rhizomes. Both parameters varied depending on the stage of development of plants and the amount of precipitation. In the years with normal precipitation, concentrations of Bacispecin ranging from 5 to 10 g/l were found to be most effective for increasing lappaconitine content in rhizomes of A. septentrionale. Whereas, under local drought conditions, the concentration of preparation should be less than 2 g/l.

In this study, ionotropic gelation method was used for the preparation of ibuprofen-loaded calcium alginate (CALG) and ethylenediamine (EDA) treated calcium alginate (EDA-CALG) microspheres. The effect of EDA-treatment on drug entrapment efficiency, particle size, morphology, swelling behavior and in vitro release characteristics of the microspheres was investigated by varying its concentration from 0.5 to 2% (v/v). The reduction in drug entrapment efficiency by a maximum of 44.60% was noted for EDA-CALG microspheres compared to untreated CALG microspheres. The particle size and swelling index of EDA-CALG microspheres were reduced with increasing EDA concentration. All the microspheres were observed to retain their spherical shapes with rough surfaces. EDA-CALG microspheres prepared using 1% and 2% v/v EDA, released almost all of its content within 7 h in pH 6.8 phosphate buffer, however, CALG microspheres were found to release the same within 3 h. The intensity of melting endothermic peak of ibuprofen reduced significantly at lower drug load as experienced from DSC thermograms. The FT-IR spectrum of pure ibuprofen, ibuprofen-loaded CALG and EDA-CALG microspheres showed the characteristic band of C = O stretching vibration of ibuprofen. Hence, this study revealed that EDA can be employed for the preparation of ibuprofen-loaded CALG microspheres to retard the drug release to some extent.

Petroleum based fossil fuels used to power most processes today are non-renewable fuels. This means that once used, they cannot be reproduced for a very long time. The maximum combustion of fossil fuels occurs in automobiles i.e. the vehicles we drive every day. Thus, there is a requirement to shift from these non-renenewable sources of energy to sources that are renewable and environment friendly. This is causing the need to shift towards more environmentally-sustainable transport fuels, preferably derived from biomass, such as biodiesel blends. These blends can be made from oils that are available in abundance or as waste e.g. waste cooking oil, animal fat, oil from seeds, oil from algae etc. Waste Cooking Oil(WCO) is a waste product and so, converting it into a transportation fuel is considered highly environmentally sustainable. Keeping this in mind, a life cycle assessment (LCA) was performed to evaluate the environmental implications of replacing diesel fuel with WCO biodiesel blends in a regular Diesel engine. This study uses Life Cycle Assessment (LCA) to determine the environmental outcomes of biodiesel from WCO in terms of global warming potential, life cycle energy efficiency (LCEE) and fossil energy ratio (FER) using the life cycle inventory and the openLCA software, version 1.3.4: 2007 - 2013 GreenDelta. This study resulted in the conclusion that the biodiesel production process from WCO in particular is more environmentally sustainable as compared to the preparation of diesel from raw oil, also taking into account the combustion products that are released into the atmosphere as exhaust emissions.

Since the division of South and North Korea in 1945, there has been little exchange in science and technology, despite some interchange in a few fields including the chemistry area. Accordingly, the difference in scientific and technological terminology between the two Koreas has become intensified. This is because North Korea carried out a campaign to purify the Korean language and blocked the inflow of foreign words. They also tried to convert into their own North Korean terms in many fields. This circumstance in North Korea aggravated the heterogeneity of inter-Korean scientific and technological terms. In particular, the heterogeneity of chemical terminology has worsened due to the different characteristics of the technology donor countries such as the United States and Japan in South Korea, and China and the Soviet Union in North Korea between the two Koreas and the different way of technological development. The purpose of this study is to collect chemical terminology data used in two Koreas and analyze similarities and differences. Through comparative analysis of inter-Korean terminology in the chemical field, it can be possible to recognize how the chemical terms between the two Koreas have changed since the division and the degree of heterogeneity based on different technical systems and language policies. The outcome of this study would present basic data on the unification of chemical terminology in preparation for before and after unification, and contribute to communication and academic exchange between researchers in the inter-Korean scientific and technological fields, including chemistry.

Rural spaces are experiencing an increasing demand for novel functionalities and adaptations driven by technological advancements in agriculture and rural areas. This study aimed to investigate the public perception of rural spaces in the context of evolving agricultural technologies, specifically focusing on photovoltaic power generation, and the ensuing competition among various functions of rural spaces. A survey was conducted with a participant sample of 330, revealing that the majority of respondents prioritize agricultural production as the primary function of farmland. Furthermore, the survey results indicated that the installation of solar panels on farmland is perceived as a complex issue that affects multiple aspects, such as the landscape, local economy, ecological environment, climate change, and income. Additionally, disparities in responses to landscape-related questions were observed based on age, perception of agricultural land functions, and opinions on technological adoption. This finding suggests that the landscape is poised to become a significant factor in future agricultural and rural transformations. The findings of this survey can provide valuable contributions to the preparation of changes catalyzed by advancements in agricultural technology. Moreover, they offer guidance on the key factors that need to be taken into account when introducing new functions to rural spaces.

본 연구는 범국가적으로 일자리 창출을 위한 창업정책이 우선 국정과제로 대두된 오늘날 과연 창업자가 얼마나 잘 준비하여야지만 성과를 낼 수 있을까 하는 의문에서 출발하였다. 성과를 측정하는 기준은 목적에 따라 다르겠지만 일반적으로 기업의 성과는 기술적 성과와 경제적 성과로 구분할 수 있다. 본 연구에서는 연구대상 기업들의 업력이 주로 2~3년차의 초기 기술창업 기업임을 감안하여 우선 얼마나 기술적 성과를 거두고 있는지 중점 살펴보고자 한다. 기업성과에 영향을 미치는 수많은 변수 중에서 어떤 변수가 가장 큰 영향을 미칠 것인가에 대한 연구가 많이 이루어졌다고 할 것이나, 과연 어떤 변수가 기업의 성과를 확실하게 측정할 수 있는지에 대하여서는 회의적이다. 이에 본 연구는 창업준비정도를 기술창업자가 실제로 창업을 준비하는 기간인 창업준비기간과 창업하기 전 직무경력을 파악할 수 있는 동업종종사기간을 독립변수로 또 조절변수로는 정부나 지자체가 지원하는 각종 창업지원사업의 활용도를 파악할 수 있는 지원사업수혜금액을 가지고 기술적 성과에 대한 실증분석을 실시하였다. 검증 결과 기술창업자의 창업준비기간은 기술적 성과에 유의적인 정(正)(+)의 영향력을 발휘하는 것으로 확인되었으나 기술 창업자의 동업종 경력을 확인할 수 있는 동업종종사기간은 기술적 성과에 일반적인 기대와 달리 부(否)(-)의 영향력을 발휘하는 것으로, 또, 지원 사업수혜금액과 동업종종사기간 사이의 조절효과는 부(否)(-)의 유의성이 있는 것으로 창업준비기간과는 유의적인 조절효과가 없는 것으로 확인 되었다. 본 연구는 최근 청년들의 일자리 창출을 위해 범국가적으로 각종 정책이 수립 집행되는 현실에서 과연 창업정책 입안자들이 어떻게 정책적 고민을 해야 하는지와 창업예정자나 창업을 준비 중인 사람들이 어떻게 창업을 해야 할 것인가에 대한 미력하나마 방향을 제시하였다는 점에 의미를 두고자 한다.
