The experiences of national unification in other countries show that the military integration is one of the most important and difficult issues in the unification process. As the primary role of the military is to manage violence, the issue of military integration is directly related to the stability and development of the newly unified country. If the military integration is unsuccessful, integration in other areas and even the national unification itself can eventually be threatened. The military integration on the Korean peninsular in essence is focused on the two Koreas' military organizations, then moves to construct a new military organization of the unified Korea. In addition to the organizational integration, however, other national and social factors must also be addressed for the unified Korea to stably maintain the newly organized military. The purpose of this study is to examine some issues in the process of the military integration of unified Korea, and the conclusions are as follows: First, the primary objectives of defense policy and military strategy should deal with the following issues- the improvement in the predictability of enemy maneuver through firm deterrent capabilities and an early warning system, the enhancement of the combined operation capabilities, the improvement in defense readiness through standing troops, and vigorous efforts for Military Technology Revolution. Second, the structure of the armed forces and the command system should be arranged with the aim of defending the peninsular from the potential threat of other countries and of preventing and eliminating domestic instability. Third, the defense budget for the new military should be alloted at least 3% of GDP, and the military ought to have active troops of between 500,000 and 600,000 men. The Army should have 60-70% of the troops while the Navy and the Air Force each should have 15-20%. Forth, in consideration of the North Korean nuclear situation, the procurement of strategic weapons for the three branches and especially the NBC weapons should be addressed. Fifth, the deployment of forces should be planned in accordance with the mobilization capability, deployment of enemy forces, weapons system, terrain and battle feild etc. Sixth, as for the United States Forces in Korea, their status of stationary troops should be improved. Also, the possibility of a more comprehensive multilateral security arrangement for the region ought to be explored.

Development of catalytic processes for the production of BTX-aromatics from biomass

제정호 한국공업화학회 2015 한국공업화학회 연구논문 초록집 Vol.2015 No.0

The development of processes that convert biomass into fuels and chemicals are essential to reduce dependence on non-renewable resources such as fossil fuels. In this regard, research into the production of commodity chemicals such as benzene, toluene, and xylenes (BTX) from biomass has rapidly expanded in the past decade. Catalytic fast pyrolysis (CFP), which involves pyrolysis of biomass in the presence of a zeolite catalyst, is a promising technology to convert solid biomass directly into BTX-aromatics. In this single-step process, solid biomass is fed into a fluidized bed reactor where the solid biomass thermally decomposes. The biomass vapors then enter a zeolite catalyst where a series of decarbonylation, Diels-Alder cycloaddition, and oligomerization reactions occur to form aromatics, olefins, CO, CO2, and coke. In this presentation, we will discuss how the catalytic properties of ZSM-5 and reaction conditions can be adjusted to produce the desired aromatics. In addition, we will show how the Diels-Alder cycloadditions of furans can be used to selectively make the targeted aromatics.

단감 발효 시 알코올 생성량이 높은 선별된 상업용 효모(Saccharomyces species) 3종을 이용하여 단감 증류주를 제조하여 품질 특성을 알아보았다. 단감 발효주의 pH, 환원당 및 총 당의 변화는 기존의 과실 발효주의 범위를 벗어나지 않아서 발효 과정 중 이상 발효는 없는 것으로 판단되었다. 발효 종료 후 총 균수는 8.67~8.70 log CFU/mL로 시료간에 유의차가 없었다. 총 효모수는 8.17~8.20 log CFU/mL로 시료 간에 유의차가 없었다. 아세트알데하이드 함량은 2차 증류 첫 분획물에서 UC군이 310 mg/L, LB군이 255 mg/L, LD군이 226 mg/L였으며, LB군과 UC군은 2번째 분획물에서도 200 mg/L 이상이었다. 아세트알데하이드 함량이 200 mg/L 이상인 분획을 초류로 제거하고 알코올 함량 40% 이상인 부분을 본류로 하였을 때, 알코올 함량은 LD군이 677.8 mL로 가장 높았다. 알코올 함량은 LB군과 UC군이 각각 408.0 mL 및 445.4 mL였다. 묘사 분석에서 단맛, 신맛, 신향 및 감향의 강도가 시료 간에 유의차가 있어(P<0.05) 이 4가지 묘사 특성이 감 증류주의 품질 평가에 적절하다고 판단된다. The objective of this study was to investigate the quality and sensory characteristics of sweet persimmon mashes and spirits fermented by three different yeasts [Saccharomyces species, labeled as LB (Lalvin BM 4X4), LD (Lalvin DV10), and UC (Uvaferm CM)]. In the production of sweet persimmon wines, UC had the highest alcohol content of 10.20% (v/v) after 9 days of fermentation (P<0.05). The range of pH after fermentation was 3.63∼3.75. The total aerobic bacteria and yeast contents increased until day 3 and then continuously decreased to approximately 8.60 log CFU/mL and 8.20 log CFU/mL, respectively. Reducing sugar contents were 3.37% in UC, 3.91% in LD, and 4.05% in LB after fermentation. Total sugar contents were 4.89% in UC, 6.24% in LD, and 5.47% in LB after fermentation. Two-stage single-pot distillation was conducted to produce sweet persimmon spirits. While conducting second distillation, spirits were collected every 100 mL fraction. The alcohol contents gradually decreased as more fractions were collected. The amounts of acetaldehyde were 226 mg/L for LD, 225 mg/L for LB, and 310 mg/L for UC in the first fraction. LD produced the highest volume (677.8 mL) of alcohol in its body part in comparison with LB (408.0 mL) and UC (445.4 mL). In the descriptive analysis, UC had stronger intensities of sweet aroma, sour aroma and taste, and persimmon flavor (P<0.05). Persimmon characteristics seemed to be well characterized by UC. In conclusion, LD was the most efficient in terms of production cost, whereas UC would be used to produce a more flavorful sweet persimmon spirit.

비대칭 망에서 동적 세그먼트 크기 조정을 통한 상향링크 혼잡제어

제정광(Jungkwang Je),이지현(Jihyun Lee),임경식(Kyungshik Lim) 한국정보과학회 2007 정보과학회논문지 : 정보통신 Vol.34 No.6

상향링크와 하향링크의 대역폭 차이가 큰 비대칭 망 환경에서 범용 TCP를 사용하는 경우, 상향링크의 혼잡으로 인해 TCP의 성능이 저하된다. 본 논문에서는 이러한 문제점을 개선하기 위하여 하향 링크 상의 데이타 세그먼트를 망 환경에 최적화된 크기로 전송함으로써 수신단에서 생성되는 응답 패킷의 수를 감소시켜 상향링크의 혼잡을 완화시키는 동적 세그먼트 조정 기법을 제안한다. 이 기법은 범용 TCP의 단대단 의미구조를 유지하고 송수신단의 TCP 수정 없이 망 환경에 따라 세그먼트의 크기를 최적으로 조정함으로써 상향링크의 혼잡을 완화시킨다. 제안된 기법은 송수신단 사이에 위치한 게이트웨이에 적용되어 상향링크의 혼잡을 감지하고 동적으로 망의 비대칭율과 패킷 손실율을 측정한다. 그리하여 게이트웨이는 상향링크 혼잡 발생 시 시뮬레이션을 통하여 미리 도출되어진 세그먼트 조정계수 값을 참조하고 패킷을 재조립한 후 수신단으로 전송한다. 즉, 망의 비대칭율이 큰 경우 송신단에서 전송되어지는 세그먼트의 크기를 조절하여 응답패킷의 수를 감소시킴으로써 상향링크의 혼잡을 완화시킨다. 또한 조정된 크기를 갖는 세그먼트에서 전송 도중 에러가 발생한 경우에는 빠른 복구를 위해 SACK를 사용하고 혼잡 제어 구간에서는 제안된 기법을 적용하지 않도록 하여 줄어든 응답 패킷의 수로 인한 성능 저하를 방지한다. 이를 통해 제안된 기법을 비대칭 망의 한 종류인 GEO 위성망 환경에 적용하여 상향링크의 혼잡 발생 시 성능 저하의 방지를 시뮬레이션을 통하여 검증하였다. Asymmetric networks that the downlink bandwidth is larger than the uplink bandwidth may cause the degradation of the TCP performance due to the uplink congestion. In order to solve this problem, this paper designs and implements the Dynamic Segment Size Control mechanism which offers a suitable segment size for current networks. The proposed mechanism does not require any changes in customer premises but suppress the number of ACKs using segment reassembly technique to avoid the uplink congestion. The gateway which adapted the Dynamic Segment Size Control mechanism, detects the uplink congestion condition and dynamically measures the bandwidth asymmetric ratio and the packet loss ratio. The gateway reassembles some of segments received from the server into a large segment and transmits it to the client. This reduces the number of corresponding ACKs. In this mechanism, the SACK option is used when occurs the bit error during the transmission. Based on the simulation in the GEO satellite network environment, we analyzed the performance of the Dynamic Segment Size Control mechanism.

薺楨洙 東亞大學校 1976 東亞論叢 Vol.13 No.1

This thesis attempts to delve into how the combined religious ideas of Buddhism and Confucianism had contributed toward the formation of Chinese Taoism. For this purpose, the present writer went into details the reciprocal influences of Buddhism and Taoism. This thesis places emphasis on the fact that Taoism alone is the Chinese national religion and that Chinese national character cultivated on the Taoistic foundation could best be understood in reference to the relations between the Chinese people and Opium.

With a view of increase the yield of farming and foresting, the consumption of agricultural pesticides has been greatly increased. Among many pesticides, organophosphorus chemicals have been believed to be almost nontoxic because they are not accumulative in tissue or organs. However, some studies have reported quite many cases of farmers, and foresters who have been suffered from the adverse effect of organophosphorus pesticides. This study was in this relevance attempted to examine the effects of organophosphorus pesticides upon the serum enzyme, and five most commonly used organophospnorus pesticides (EPN, DDVP, phosphamidon, malathion, diazinon) in Korea were selected for the study. For the experiment, the Sprague-Dawley rats weighting around 200gm were divided into basic diet group(control) and pesticides administered groups of 1) EPN, 2) DDVP, 3) phosphamidon, 4) malathion, and 5) diazinon. The basic diet composed of adequate solid neutrients was given to each rat orally 15-20gm per day. A half and a quarter of LD?? of organophosphorus pesticides were daily dosed to each rat in the experimental group one time in the former and three times (one time per day for 3 days) in the latter. The serum cholinesterase, GOT, GPT and alkaline phosphatase have been measured. The result obtained from this experiment are summarized as follows: 1. Cholinesterase is significantly suppressed in groups of DDVP, EPN, phosphamidon, malathion and diazinon in order. 2. GOT is increased in groups of EPN, phosphamidon, malathion, DDVP and diazinon in order, especially in 24 hours group. 3. GPT is increased in groups of EPN, DDVP, diazinon, phosphamidon and malathion in order. 4. Alkaline phosphatase is increased in groups of EPN, DDVP, phosphamidon, malathion and diazinon in order.
