  • This study was conducted to estimate the effect of sex, breed and on the basis of the records on 300 pigs of Duroc, Landrace and Yorkshire breeds raised at the National Institute of Animal Science. Yorkshire was observed to be superior to other breeds between 90 to 110 kg of body weight. Thicker backfat was estimated in the B-mode than in A-mode of 110 kgs range than in 90 kgs. Loin eye muscle area was larger in the final weight of 110kg than in 90 and the Duroc had significantly (p<0.05) larger loin eye muscle area than other breeds. Thinner backfat was observed in males than in females in both modes of backfat measurements and in both of the final weights of test. Females had significantly larger loin eye muscle area than males, and the difference between the two sexes were larger in the final weight of 110 kg than in 90 kg. Analysis models concluded that backfat thickness certainly influences the body weight gain when at 90 kgs and 110 kgs analysed with A-mode and B-mode respectively.

  • 블루베리는 진달래 과(Ericaceae) 산앵도나무 속(Vaccinium)의 낙엽성 또는 상록성의 저수고성 또는 반교목성의 과수로, 뉴욕 타임즈가 선정한 세계 10대 장수식품의 하나로 알려져 있다. 우리나라에는 전부터 정금나무, 월귤나무, 모새나무, 산앵도나무 등이 자생하고 있으나, 경제적인 가치가 있는 종은 Vaccinium Cyanococcus로 북미지역에서 육성된 품종들이 들어와 재배되고 있다. 처음 도입된 해는 1965년경으로 지금도 40년 이상 된 나무들이 있고, 상업적으로 재배되기 시작한 것은 2000년이고 공식적인 연구는 2004년 국립원예특작과학원에서 시작되었다. 한국블루베리협회 소식지에 주기적으로 기록되기 시작한 재배면적은, 2007년 112ha, 2008년 217ha, 2009년 313ha, 2010년 534ha이었다가 2011년 1,082ha로 크게 증가하였다. 시도별 재배면적은, 전북이 254ha로 가장 많았고, 충남 186ha, 전남 169ha, 경북 157ha, 충북 118ha, 경기 90ha, 경남 58ha, 강원 47ha, 제주 4ha 순이었다. 특히 2010년부터 2011년까지 한 해 동안 블루베리 재배면적이 크게 증가한 것은 각종 언론매체에서 블루베리 기능성에 대한 홍보와 소비자의 인식 증가와 더불어 새로운 소득 작물로 농가 수요가 확대되었기 때문이다. 이는 블루베리 묘목의 수입이 2009년 327천주에서 2010년 702천주로 크게 증가한 것으로도 알 수 있다. 아울러, 국내로 수입되는 냉동과, 건조과의 수입량도 큰 폭으로 증가하였다. 냉동 블루베리 수입량은 2009년 812톤에서 2010년 4,700톤으로 대폭 증가하였는데, 주요 수입 국가는 미국(3,931톤), 캐나다(557톤), 프랑스(70톤), 태국(18톤), 중국(16톤) 등으로 주스 등 가공품 시장의 수요 증가에 따른 것이다. 건조 블루베리의 수입도 2009년 14톤에서 2010년 54톤으로 증가하였다. 2011년 국내산 블루베리 가격은 생과 1kg에 40,000~50,000원선이었으나 35,000원에 판매하는 농장도 있었고, 냉동과를 62,000원도 판매하는 농장도 있었다. 미국 오레곤 주에서 생산한 블루베리 생과가 금년 7월부터 91톤에서 227톤 정도 수입될 것으로 예상된다. 블루베리의 국내 생산량이 많아지고 수입까지 되면, 농업인들은 더욱 품질 좋은 과실을 생산하도록 노력해야 하고, 잼, 식초, 와인 등의 가공식품 외에 과자, 케익, 머핀 등 베이커리용으로 많이 소비되도록 하며, 지역의 다른 상품들과 연계하여 찾아가고 싶은 관광 개발 등으로 소비 촉진을 위해 고심해야 할 것이다.

  • Magnetic method is rapid, cheap and simple geophysical exploration technique, and has wide range of applications such as resources prospecting, geological structure investigation and even geotechnical and environmental problems. Especially, aeromagnetics gives fundamental and useful geoscientific data fnr not only assessment of potential resources, but also national land planning. Magnetic method, perhaps the oldest geophysical technique, was relatively early introduced into Korea. Documents during Japanese occupation says that magnetic method was used for exploring metallic ore deposits and hot spring, and that a geomagnetic observatory was operated. From mid 1950's, after Korean War, magnetic explorations for natural resources such as metallic ore, uranium, coal, and groundwater were intensively executed for industrialization. Apache aeromagnetic survey project during $1958{\sim}1959$ and its ground follow-up surveys are typical and important cases in those days. Magnetic survey techniques were rapidly advanced during 1970's and 1980's with improvements of instruments, growth of geophysical manpower, and availability of computers. The national aeromagnetic mapping project by KIGAM in 1981 showed the improved technical capability of those days. Decline of mining industry since mid 1980's moved the exploration objects from traditional resources to new ones such as groundwater and geothermal resources, and applications to investigation of geological structure were revived. Recently appeared applications such as natural hazard assessment, and engineering and environmental studies increased the magnetic method's utility in the realm of exploration.

  • Because of its strong potential for health hazards, the concentration levels of airborne lead (Pb) have been circumscribed by environmental laws in many countries. In this study, we made a comparative study on the environmental behavior of Pb for the acquisition of its distribution characteristics using data sets collected from major cities in Korea for a period of 6 years (1998 through 2003). According to this study, Pb concentration decreased slowly in most industrialized cities of Koreathroughout the whole study. period. In contrast, such temporal signals were not evident in data sets collected from residential, commercial, and grassland areas. Although seasonal patterns generally exhibited the occurrences of high Pb concentration during the spring, results appear to reflect the influence of Asian Dust (AD) in the springtime. The results of our study clearly indicate that Pb distribution is strongly influencedby source types in relation to their land use patterns. Comparison of our Pb data sets with that of other countries indicates that Pb concentration levels obtained from relatively cleaner districts of Korea are still significantly higher than other countries. The results of this analysis generally indicate that Pb concentrations in most areas are affected by the type and strength of man-made activities. Considering that most areas are affected by a variety of pollutants, continuous efforts are needed to control Pb concentrations in the atmosphere.

  • As the society turns into more of an information an technology centric society, the importance of information security is being increased these days. Recently, as the number of leaking accidents of personal information and valuable industrial technology is on the rise, every field of industry endeavors to come up with a security solution. In particular, since defense industry is a field where it establishes national defense power that is essential of national security, it requires higher standards of security solutions than any other ordinary fields of industry. According to Defense Industry Security Work Instructions, defense industry firms from security organizations and employ a security worker corresponding to the firm's scale and conditions. In an environment where essential information and technology are stored and managed in information and communication system or storing media, the duty and role of IT security workers are crucial. However, there is a shortage of systematic analysis on the work of IT security workers and development of curriculum to enhance their professionalism. Thus DACUM process, a job analysis technique, was used to identify IT Security workers' duties and responsibilities and verify the validity and credibility of the deducted results from the survey. The findings of this study will help in development of IT security duty in defense industry and can be used as baseline data for the development of curriculum and amendments of related regulations.

  • The price of land in Jeju is reaching a new high every day and this phenomenon not only causes real difficulties for the purchase of real estate by local residents, but also results in psychological deprivation. Therefore, this study analyzes the factors causing the increase of the land price in Jeju, in order to examine the measures required to stabilize the land price which is continuously rising. As a result of this study, we developed a land price prediction model including seven variables, including the 'inflation rate', 'interest rate', and 'population'. According to the model, land prices in Jeju are expected to rise steadily, and it is predicted that in 2020 the price will increase to 170% of that in 2015 and will triple by 2025. Based on the results of this study, this study suggested policy alternatives, such as 'Establishing a tourism policy for managing the number of tourists' and 'increasing the approval standards for development activities'. The two policies proposed in this study can be implemented as a regional initiative, which may be less effective than the changes in the national system, but it is meaningful that the efforts to stabilize the land price will continue at the regional level.

  • Wastewater treatment (WWT) technology has been developing from simple pollutant treatment to energy and resource-saving advanced technology, and various technologies combined with IT and BT are developed to minimize the amount of pollutant and toxic substance discharge to the public water areas and to improve operational efficiency. To examine the development trend of domestic wastewater treatment technology, the registered patent technologies were surveyed, classified and analyzed by year and sector. This paper considers the status of patent registration related to WWT from 2010.1 to 2017.5 in terms of the number of specific technical areas, and the trends are analyzed based on the 10 categorization field such as biological and physicochemical treatment process, equipment and device, material, sludge treatment, membrane, process control and 42 specific technical areas. A total of 3,356 patents have been registered since 2010, and the number of patents has been decreasing since the peak at 2013 and maintains 3~400 per year. The total number of patents has not yet been less than other countries, but the number of patents of more advanced technologies, which can lead the global market, such as process monitoring, new concept processing and equipment technologies is still insufficient compared to developed countries.

  • Hospice and palliative care in Taiwan has been growing continuously. The 2015 Quality of Death index, as rated by the Economist Intelligence Unit, ranked Taiwan first among Asian countries and sixth in the world. In this review article, we highlight three particular areas that might have contributed to this success; the laws and regulations, spiritual care and research network. Finally, we discuss the future challenges and prospects for Taiwanese encounters. A systemic review was conducted with the keywords "hospice palliative care Taiwan" using PubMed. The passing of the "Natural Death Act" in 2000 set the example and established a landmark for patient autonomy in Asia; it guarantees the patient's right to request that medical staff do not resuscitate (DNR) them and to reject other futile medical treatments at the end of their life, thus reflecting the importance of palliative care from the policy perspective. In 2015, Taiwan passed another pioneering law entitled the "Patient Autonomy Act". This law states that a patient may decline medical treatment according to his/her own will. Taiwanese indigenous spiritual care was launched in 2000. It requires a Buddhist Chaplain to successfully complete a training program consisting of lectures, as well as bedside practicum before applying Buddhist practices to end-of-life care. The Japan-Korea-Taiwan research network was established for the purpose of enabling collaborative research for the East-Asian collaborative cross-cultural Study to Elucidate the Dying process (EASED) cohort. With consensus from the government and society to make it a priority, hospice and palliative medicine in Taiwan has been growing steadily.
