This paper estimates changes in the total factor productivity and technical efficiency change index and the technical change index using the Malmquist productivity index (MPI) in fishery-processed wholesale products over the time period spanning 2006-2008. The model considers a number of employees and operating costs as input factors, and sales and EBIT (earnings before tax and interest) as output factors. The results demonstrate that, between 2006 and 2007, there has generally been no technical progress, although a small improvement in productivity was detected in the sales scale of 10 billion won-50 billion won. Between 2007 and 2008, there was technical progress in the majority of DMU, except within the range of 20 million won-10 billion won. Wilcoxon's rank-sum test, however, demonstrates no statistically significant differences in productivity between the two periods.

This study is to disclose the gilding technique and distinctive features of using surface improvement technique in ancient gilt. There are many kinds of the ancient gilding technique so this thesis mainly focused on mercury amalgam gilding. Gilding technique can be largely divided into two branches – the cladding and amalgam method - in ancient periods. The researches have been carried out on two parts; the first is to find the making progress of amalgam on all sort of the gilding materials and the second is to show features of the gilded layer among basic metals. As a result of this experiment, to achieve good quality of amalgam, suitable particle size of the gilding material should be needed and the heating, a primary factor, has an effect on amalgam to be formed. Aspecial features of amalgam gilding, according to changing the basicmetal, would be influenced by chemical attraction for the mercury, condition of the surface and some other factors. A platers abilities and the making progress of amalgam would be influenced by a uniform and good gilding layer. In conclusion, it should be profoundly studied and investigated on the ancient gilding techniques and gold-gilt relics.

Since its inception in 2009, medical tourism in South Korea has continued to progress. Reaching its peak in 2019, the industry experienced a sharp decline in inbound patients after the COVID-19 pandemic in 2020 due to international border closures and a surge in patient numbers. However, from 2021 onwards, there has been a gradual increase in inbound patients. The purpose of this study was to classify the top 12 countries based on the number of actual patients entering the country from 2014 to 2022, using statistics from the Korea Health Industry Development Institute. It also analyzed the changes in the number of foreign patients visiting Korea and the evolving proportion of actual patients compared to short-term visa arrivals on a yearly basis. Through this content, we aim to examine the trends on a country-by-country basis and identify the direction in which the future of South Korean medical tourism should progress. By focusing on healthcare, we intend to pinpoint areas that require attention and improvement, as well as highlight any existing issues. Through modifications and enhancements based on these considerations, we aspire to attract a significant number of foreign patients, thereby promoting South Korea's medical technology on a global scale.

결론적으로 위성에 의한 강우관측은 지금은 지구의 거의 대부분 지역에서 관측 및 모니터링과 더불어 강우를 이해하는 능력에 커다란 기여를 하고 있다. 특히 1997년 11월 TRMM의 등장으로 강우의 연직분포 및 정량적 관측이 이루어지므로서 국내에서도 위성강우의 활용연구가 급진전할 것으로 기대된다. 또한 위성강우자료를 이용한 농업 및 수자원분야에서의 연구도 기대된다. 위성강우자료를 농업/수자원 분야에 적용하기 위해서는 먼저 자료간의 결합시에 발생되는 규모(scale)와 해상도(resolution) 문제를 다루는 평가연구가 요구된다. 규모문제는 주어진 연구에 가장 적절한 구역의 개수에 대한 불확실성 때문에 발생되며, 해상도 문제는 해당자료를 저해상으로 결합하여 분석하게 되면 기대치 이상의 정보손실을 야기시키기 때문이다. 이와 같은 의문점이 어느 정도 구명된다면 위성강우자료를 이용한 연계연구는 무궁무진하다고 말할 수 있다. 예를 들면 농업분야에서는 위성강우에 의한 격자기반(grid-based)의 토양수분 및 지하수위 변화, 농경지 침수지역 예측 등에, 수자원분야에서는 공간강우-유출해석에 의한 홍수예 · 경보시스템의 향상, 도시지역 홍수범람지역의 예측 등에 활용할 수 있다.

Unfavorable weather and soil conditions reduce rice yield and land and water productivity, aggravating existing encounters of poverty and food insecurity. These conditions are foreseen to worsen with climate change and with the unceasing irrational human practices that progressively debilitate productivity despite global appeals for more food. Our understanding of plant responses to abiotic stresses is advancing and is complex, involving numerous critical processes - each controlled by several genetic factors. Knowledge of the physiological and molecular mechanisms involved in signaling, response and adaptation, and in some cases the genes involved, is advancing. Moreover, the genetic diversity being unveiled within cultivated rice and its wild relatives is providing ample resources for trait and gene discovery, and this is being scouted for rice improvement using modern genomics and molecular tools. Development of stress tolerant varieties is now being fast-tracked through the use of DNA markers and advanced breeding strategies. Large numbers of drought, submergence and salt tolerant varieties were commercialized over recent years in South and Southeast Asia and more recently in Africa. These varieties are making significant changes in less favorable areas, transforming lives of smallholder farmers - progress considered incredulous in the past. The stress tolerant varieties are providing assurance to farmers to invest in better management of their crops and the ability to adjust their cropping systems for even higher productivity and more income, sparking changes analogous to that of the first green revolution, which previously benefited only favorable irrigated and rainfed areas. New breeding tools using markers for multiple stresses made it possible to develop more resilient, higher yielding varieties to replace the aging and obsolete varieties still dominating these areas. Varieties with multiple stress tolerances are now becoming available, providing even better security for farmers and lessening their production risks even in areas affected by complex and overlapping stresses. The progress made in these less favorable areas triggered numerous favorable changes at the national and regional levels in several countries in Asia, including adjusting breeding and dissemination strategies to accelerate outreach and enabling changes at higher policy levels, creating a positive environment for faster progress. Exploiting the potential of these less productive areas for food production is inevitable, to meet the escalating global needs for more food and sustained production systems, at times when national resources are shrinking while demand for food is mounting. However, the success in these areas requires concerted efforts to make use of existing genetic resources for crop improvement and establishing effective evaluation networks, seed production systems, and seed delivery systems to ensure faster outreach and transformation.
