방송통신 기술의 발달과 함께 네트워크는 고도화되고 있으며, 우리나라는 IT분야 선도국가로 잘 알려졌다. 산업의 경쟁력을 대표하는 척도로서 IT 국제지수는 성과를 가시화하는 지표로서 의미가 있으며, 좋은 결과는 국격(國格)을 높이는 것으로 가치가 있다고 할 수 있다. 그러나 IT관련 기존의 국제지수들은 통신위주의 지수이며, 방송을 거의 반영하지 않고 있는 실정이다. 본 연구는 방송통신 네트워크 분야를 중심으로 객관적인 지표에 근거한 새로운 지수개발을 목적으로 한다. 이를 위해 접근, 이용, 산업환경 등 지수를 3부문으로 구분하고, 지표별 가중치를 적용하여 방송통신망 국제지수를 발굴하도록 한다. 체계적이며, 실효성 높은 방송통신망 국제지수 제공을 통해 국가브랜드 가치 제고를 하는데 기여하고자 한다.

The purpose of this study is to examine the property of climatological environment using the daily mean meteorological data measured at the serveral meteorological observatory for 30years(1961~1990). It was found that the distribution of discomfort index tended to mainly depend on the geographical situation in the same season. Major portions of Korea were subjected to continental except for some seaside districts. The discomfort index have a large(small) value in summer(winter) season. And there is a short interval(1 or 2 months) between summer and winter season in Korea.

An anti-forensic data hiding method in an NTFS index record is a method designed for anti-forensics, which records data as a file name in index entries and thereafter the index entries are made to remain in the intentionally generated slack area in a 4KB-sized index record[7]. In this paper, we propose a maximum data allocation rule for an anti-forensic data hiding method in an NTFS index record; i.e., a computational method for storing optimal data to hide data in an index record of NTFS is developed and the optimal solution is obtained by applying the method. We confirm that the result of analyzing the case where the number of index entries n = 7 is the maximum case, and show the screen captures of index entries as experimental results.

Mulberry being the only food of silkworm, Bombyx mori L., is of great economic importance to the silk industry, The success in cocoon production mainly depends on the supply of quality leaves in sufficient quantity. In mulberry, where the economic product is leaf, the uptake of nitrogen from soil is very heavy and high responses to application of nutrients have been reported. Nitrogen supports vegetative growth particularly the leaf biomass. Variation in nitrogen harvest index and other physiological and yield contributing traits were estimated in five mulberry genotypes. Considerable variation was observed for nitrogen harvest index, protein yield per plant and harvest index. The correlation studies indicated the protein yield per plant was significantly correlated with leaf yield, nitrogen content in leaf, nitrogen harvest index and harvest index. The broad sense heritability estimates revealed that harvest index showed highest heritability (88.07%) followed by nitrogen content (82.52%), protein yield (70.28%) and nitrogen harvest index (66.52%).

Greenwich and Jahr-Schaffrath(1995) considered a new process incapability index(PII) $C_{pp}$, which modified the useful index $C^{\ast}_{pm}{$ for detecting assignable causes. The new index $C_{pp}$ provides an uncontaminated separation between information concerning the process accuracy and precision while this kind of information separation is not available with the $C^{\ast}_{pm}$ index. In this paper, we will study about the index $C_{pp}$ based on the bootstrap. First, we will prove the consistency of bootstrap deriving the bootstrap asymptotic distribution for our index $C_{pp}$. Moreover, with the consistency of bootstrap, we will construct six bootstrap confidence intervals and compare their performances. Some simulation results, comparison and analysis are provided. In particular, two STUD and ABC bootstrap methods perform significantly better.

포장의 합리적 유지관리를 위해서는 기본적으로 포장의 상태를 객관적으로 평가하고, 평가한 자료를 이용하여 경제성 분석을 실시함으로써 최적의 보수공법 및 보수우선순위를 결정해야 한다. 전체적인 포장 상태를 객관적으로 평가하기 위해서는 포장상태 평가지수와 같은 단일화된 평가 기준이 필요하다. 본 연구에서는 우리나라 고속도로 콘크리트 포장에 적합한 포장상태 평가지수를 개발하기 위하여 현장 상세조사 및 포장평가위원회의 평가를 실시하고, 그 결과의 회귀분석을 통해 포장평가지수를 개발하였다. 또한 개발된 포장평가지수를 이용하여 포장유지관리에서 이용되기 위한 보수공법그룹을 제시하였다. 개발된 포장평가지수의 상관계수는 0.68이었으며, 콘크리트 포장평가지수에 사용된 독립변수들은 종단평탄성, 균열, 패칭 등이었다.

Purpose: This study examines the relationship between formation of employment subcenters and regional industrial structures in Incheon. Research design, data, and methodology: We used the five-year panel data from 2012 to 2016 in 146 basic municipal units of Incheon to analyze panel regression models. Gross employment density and employment to population ratio were used as indicators of employment subcenters formation. The entropy index and Hachman index were used for analyzing the diversity and heterogeneity of industrial structures. Result: The analyses of two panel regression models showed that for the formation of employment subcenters, both the Entropy and Hachman index were significantly negative in most models. But tertiary industry was shown to have a significant positive relationship in all models. In the wholesale and retail sector, it was found that the average number of employees in the employment subcenters is significantly higher than that in the non-employment subcenters. Conclusions: The specialization of the industrial structure rather than the diversification contributes to the formation of the employment subcenters in Incheon. In particular, it can be considered that the wholesale and retail sector plays a very important role in forming the employment subcenters in many areas of Incheon.

First, the trade competitiveness of the textile industries in South Korea has been weakening, whereas, the counterpart in China has been growing as the main export industries. Second, the trade competitiveness of the mechanics industries in South Korea has been increasing and appearing as the new promising strategic export industries. And, the counterpart in China also shows that it has been rising, while the country’s level of the imports specialization index has been weakening. Third, the trade competitiveness of the transportation industries in South Korea has been rising as the export-oriented and at the same time, privileged industries. And, China has also been rising as South Korea has been in the case, whereas, imports specialization index has been weakening. Fourth, the trade competitiveness of the electrical and electronic industries in South Korea has relatively been at the very high level, giving rise to the core export-privileged industries in the South Korea. And, China has been emerging as the new strategic export industries, as its industry structure has been shifted from the import- specialization and export-specialization industries. Fifth, it is indicated that the trade in the both South Korean and Chinese industries of fable materials, mechanics goods for computer & office, and goods for electric mechanics has been going favorable and brisk.

There are many asset prices which are interlinked and have a bearing on the stock market index. Studies have shown that the interrelationship among these asset prices vary and are inconsistent. The ultimate aim of this study is to examine the dynamic relationship between gold price, oil price, exchange rate and stock index. Monthly time series data has been utilized by the researcher to examine the interrelationship between four variables. The relationship among stock exchange rate index, oil price and gold price have been undertaken using regression and granger causality test. The results indicate that the exchange rate and oil price have an indirect influence on NIFTY; whereas gold price had a direct impact on NIFTY. It is evident from the results that volatility in the price of gold is mainly dependent on the exchange rate and vice versa. All the variables affect NIFTY in some way or the other. However, gold has a direct and vital relationship. From the study findings, it can be concluded that macroeconomic variables like commodity prices and foreign exchange rate, gold and oil, have a strong relationship on the return on securities at the national stock exchange of India.

본 연구에서는 미술품의 경매 현황에 대해 알아보고 미술품 가격 지수의 국외 및 국내 현황에 대해 조사한다. 경매는 공개된 경쟁 입찰을 통해 미술품의 창작자로부터 수집가로 통하는 시장의 역할을 수행한다. 미술품의 사적 거래를 통한 음성적인 거래가 아직은 큰 부분을 차지하고 있는 국내 미술품 시장의 현황에서 경매의 역사는 짧지만 양성적인 거래인 경매에 의한 효과가 크기 때문에 앞으로는 경매가 더욱 활성화 할 것이다. 미술품 가격 지수는 선진국에서는 투자자들에 대한 투자 지침으로 역할하며 개발되어 잘 활용되고 있다. 그러나 아직 국내에서는 미술품 가격 지수에 대한 개발역사가 일천하며 개발된 미술품지수조차도 널리 활용이 되지 않고 있는 실정이다. 경매에서 낙찰된 작품들에 대해서만 가격정보가 투명하게 공개되므로 경매는 가격지수 개발을 위한 필수적인 토대라고 할 수 있다. 본 연구에서는 선진국과 국내 미술품 가격 지수에 대한 비교를 통해 한국형 미술품 가격지수들의 특징과 활용방안에 대해 검토한다.
