The import content of exports (ICE) is defined as the amount of foreign input embodied in one unit of export, and it has been used as a measure of the degree of integration into the global production network. In this paper, we suggest an alternative measure based on the decomposition of gross output and imports into the contributions of final demand terms. This measure considers the manner in which a country manages its domestic production base (gross output) and utilizes the foreign sector (imports) simultaneously and can thus be regarded as a more comprehensive measure than ICE. Korea's input-output tables in 1970-2018 are used in this paper. These tables were rearranged according to the same 26-industry classification so that these measures can be computed with time-series continuity and so that the results can be interpreted clearly. The results obtained in this paper are based on extended time-series data and are expected to be reliable and robust. The suggested indicators were applied to these tables, and, based on the results we conclude that the overall importance of the global economy in Korea's economic strategy has risen and that the degree of Korea's integration into the global production network increased over the entire period. This paper also shows that ICE incorrectly measures the movement of the degree of integration into the global production network in some periods.

In order to efficiently collect data, it is essential to locate the facilities and analyze the movement data. The current technology for location collection can collect data using a GPS sensor, but GPS has a strong straightness and low diffraction and reflectance, making it difficult for indoor positioning. In the case of indoor positioning, the location is determined by using wireless network technologies such as Wifi, but there is a problem with low accuracy as the error range reaches 20 to 30 m. In this paper, using BLE 4.2 built in Raspberry Pi, we implement Bluetooth Smart Ready. In detail, a beacon was produced for Advertise, and an experiment was conducted to support the serial port for data transmission/reception. In addition, advertise mode and connection mode were implemented at the same time, and a 3-count gradual algorithm and a quadrangular positioning algorithm were implemented for Bluetooth RSSI error correction. As a result of the experiment, the average error was improved compared to the first correction, and the error rate was also improved compared to before the correction, confirming that the error rate for position measurement was significantly improved.

This paper has focused on comprehending the interior designs and characteristics of modern department stores in Korea by looking into the birth and changes of those built under the Japanese Forced Occupation Period. The first modem department stores including Mitsukoshi, Georgia and Hwashin Department Stores began to appear in Korea under the Japanese Colonial Rule. They considered a variety of architectural elements like construction planning, shop arrangement, path of customer movement and interior design. The interior of modem department stores aimed to pursue the so-called modernization movement, but failed to fully contain the unique characteristics of the times in that particular period. Modem department stores took on new western styles prevailed in Korea and were characterized by the eclecticism in which various architectural forms exist together. In other words, their interiors implied a sign of the times in the confusing and corrupt world then. Especially those modern department stores were designed, repaired and extended by foreign designers who were ignorant of the history of Korean architecture. What is worse, their further remodelling practices made big mistakes by considering only functional and economical aspects and giving a back seat to the architectural and historical value of existing modern department stores. Therefore, we should make more efforts to study and conserve the fundamentals of modem architectures like modem department stores in order to have better understanding of the aesthetic value of indoor space and facilitating smooth communication between past and present.

This study is about the strife patterns in modern fashion and the characteristics inherent in them. The study was aimed at offering the basic materials to develop the creative design that can show various visual expression effects. In terms of method, the study was led by the analysis of documents; domestic and foreign fashion, collection magazines etc were used to analyze the strife patterns in modern fashion. According to the findings, the study used the rearrangement of the strife patterns at the same intervals, the arrangement of different strife patterns within one single item, the hybrid arrangement of strife patterns and different patterns, and the use of strife patterns for a certain part of clothing for the purse of emphasis or decoration. First, the characteristics inherent in such strife patterns showed clear simplicity using the same repetition of simple lines or the two colors of black and white. Second, strife patterns changed silhouettes by causing optical illusion, and showed the rhythm effects, such as swelling, wave or movement by distorting and controlling lines or forms. Third, based on irregular intervals or multi-strife, the concept of unclear disharmony and inconsistency was shown with the beauty of hybridharmony by blending various strife patterns with each other, or strife patterns with different patterns, and thus expressing composite images.

조선 후기 대항 공론장의 특성을 분석하고자 역사적, 규범적, 분석적 차원으로 나누어 검토하였다. 그 결과, 당시 민(民)을 중심으로 형성된 대항 공론장은 반(半)봉건 반(反)외세적 성격을 띤 하부 공론장의 역할을 함을 발견하였다. 즉, 조선 후기의 대항 공론장은 당시 정치사회적 환경을 극복하고, 생존의 문제를 해결코자 한 반(半)봉건 반(反)외세적 성향이 가진 생동적인 공론장이었다. 그러나 이러한 조선 후기 대항 공론장은 지속성을 유지하지 못했다. 하지만 이후 항일운동의 발판이 되었고, 나아가서는 오늘날 민중운동의 이념적 근거가 되었다는 것에 그 의의가 있다고 할 수 있다.

Chrysanthemums (Chrysanthemum morifolium) are susceptible to tobacco mosaic virus (TMV). TMV-based expression vectors have been used in high-throughput experiments for production of foreign protein in plants and also expressing green fluorescent protein (GFP) to allow visualization of TMV movement. Here, we used TMV expressing the GFP to examine the infection of chrysanthemum by a TMV-based expression vector. Viral replication, movement and GFP expression by TMV-GFP were verified in upper leaves of chrysanthemums up to 73 days post inoculation (dpi) by RT-PCR. Neither wild-type TMV nor TMV-GFP induced symptoms. GFP fluorescence was seen in the larger veins of the inoculated leaf, in the stem above the inoculation site and in petioles of upper leaves, although there was no consistent detection of GFP fluorescence in the lamina of upper leaves under UV. Thus, a TMV-based expression vector can infect chrysanthemum and can be used for the in vivo study of gene functions.

The foreign superior players and national team players' turning phase was measured, compared and analyzed to help the representative players improve the skill of turn. The underwater video camera used to analyze and evaluate the representative players' skill of turn in detail and the result is as follows. 1. The record for the phase of turn was similar to the rank of the last record. The improvement of the skill of turn was required because Korean players' record was lower than the foreign players' one. In case of 200m events the 1st turn was the fastest and it took more time as the turn is repeated. 2. It shows that the preparation phase and turing motion cause the difference between the players and within one player. 3. The horizontal movement of center of gravity moves to turning point slowly in the preparation phase, does not move nearly in the turning phase and increase again in the propulsion phase. Good record has short time for turn phase. The result means that the shorten the turning phase is the most important factor. Therefore the preparation for this is required. The vertical movement is maintained or increase a little and then move to from the turning phase. 4. The characteristic of horizontal velocity in center of gravity is that there is any big changes at the preparation phase, the faster velocity is found from the better record and the accelerating time is fast at the propulsion phasen. The wrong motion is made by not using the swimming velocity for fuming and waiting and more time is required by this. 5. The angle of knee when the player touch the turning point is 106.22-135.56 and the maximum angle of knee during the driving after the touch of tuning point is full extension. The size of maximum angle of knee did not match with the required time of propulsion phase. It seems that the individual difference is big when the players touch the turning point the angle of knee and the research for the individual angle which can reveal the maximum power should be carried out. The national team player's skill for the him is behind the foreign players' one and a lot of problems were found. It shows that the players could not practice the skill for turn during the training. The 1st reason for it is the various facilities like underwater window or analyzing equipment like underwater camera with which the coaches can teach and correct the players' detailed skill. It is need to evaluate the players' detailed skill exactly and correct it by objective data to complete the good skill in the future. In this regard, the investment for the facility is necessary.
