The Asia-Pacific region is not typically seen as one geographic or socio-economic space. Yet, 58 regional economies occupying the space of 28 million square kilometers from Turkey in the West, Russian Federation in the North, French Polynesia in the East and New Zealand in the South belong to the Economic and Social Commission of Asia and the Pacific (ESCAP). This commission provides a forum for member states that "promotes regional cooperation and collective action, assisting countries in building and sustaining shared economic growth and social equity". In 2013, ESCAP's members adopted the Bangkok Declaration to enhance efforts towards deeper regional economic integration. Yet this document neither proposes a concrete modality or modalities of achieving deeper integration, nor provides a sense of distance of individual countries to a "perceived" integrated Asia-Pacific.This paper aims to comprehensively quantify recent integration efforts of economies in the Asia-Pacific region. We provide an "index of integration effort" based on twelve metrics that measure the relative distance of a given economy to the region as an economic entity. Generally, we find that while the region has trended towards becoming integrated in general, both the level of integration and integration effort are inconsistent among Asia-Pacific economies. We discuss potential applications and extensions of the index in developing our perspective of the region's economic and social dynamics.

The treatment of X-ray was manipulated with the large focus of X-ray which was produced the capacity of 90 kilovoltage and 30 milliamphere in the distance of 50 centimeter. The germination of each gruop irradiated with X-ray for 5, 6, and 7 seconds was more delayed in the growth of carrot seed than those of the control group. However the germination of each group irradiated with X-ray for 2, 3, and 4 seconds was rather accelerated than those of the control group. The irradiation of ultraviolet light was carried out in the distance of 20 centimeter by Toshiba germidicial lamp which appeared the wavelength of 2537A$^{\circ}$. The germination of each group irradiated with ultraviolet light for 9, 15, 20, and 40 minutes was more delayed than those of the control group, but the germination of carrot seed was accelerated by adequate dosage of ultraviolet light. Consuquently it was suggested for the author that the inhibited substance contained in carrot seed would be certain fatty substance, becasue the germination of carrot seed was more accelerated by the treatment of acetone than those of X-ray and ultraviolet light.

도시의 발달로 도시 외곽 도로의 산지를 통과하는 도로의 건설이 요구되지만 그 계획을 실행함에 있어서 많은 문제점들이 있다. 이것은 도로계획시 노선의 위치를 결정하는데 있어서 토공작업을 예측하고, 경관을 식별하여, 식생 및 토지이용 관계를 해석하므로 계획과 실행에서 도움을 주는 것이다. 본 연구에서는 36km에 달하는 광주 외곽을 순회하는 도시고속순환도로 중 제 1구간인 동광주 I.C 에서 소태 I.C까지의 노선의 일부 5Km를 연구 대상으로 결정하여 G.I.S에 의해 해석하였다. 그리고 설계도의 계획고와 같은 자료를 이용하여 조망 위치에 따라 달라지는 경관을 구간별로 도시하였으며, 광주의 명소인 무등산 주위를 순환하는 본 연구지를 G.I.S기법을 이용하여 지형경관을 해석하여 결론을 얻었다

인삼의 자엽과 callus에 Biolistic system을 이용한 비선택성 제초제인 bialaphos에 대한 내성을 갖게 하는 PAT 유전자의 형질전환효율 향상 및 형질전환체의 유전분석에 관한 실험을 수행하였다. 자엽의 경우에는 형질전환율이 약했지만 callus의 경우에는 target distance 9 cm, rupture disk-macro-carrier gap distance를 1/3"로 했을 때 가장 양호한 형질전환 결과를 보였다. 형질전환된 인삼식물체에서 PAT 및 NPT 유전자의 존재 여부를 확인하기 위해서 PCR을 수행한 결과 정상 식물체서는 전혀 PCR product가 형성되지 않은 반면 형질전환체 모두에서 PAT (약 300 bp)와 NPT (약 800 bp) 유전자의 band를 확인하여 각각의 유전자가 삽입되어 PAT 및 NPT IIgene이 도입된 형질전환체임을 확인할 수 있었다. 있었다.

Fire detectors are designed to minimize loss of life from a fire alarm system as an alarm to help evacuate more quickly until the completion of the evacuation alarm should be continued. the purpose of such alarms in order to achieve the characteristic fire heat release rate reaches a certain level, or when a certain time has elapsed, when the heat detector is to be alarms to answer. Requires a quick response, it is desirable to install the sensor as much as possible, but taking into account the cost of installation problems by engineering approach to minimize the quantity and rapidity of detection capability should be increased. In order to increase the rapidity of fire detectors in a room according to the height of the sensing period is to be maintained the optimum distance of the fire detector detects characteristics should be considered. Differential spot-type heat detectors installed domestic basis, depending on the type of sensor that can detect one sensor area is limited and less than 4m ceiling height regulations and simply double the number in excess of 4m and intended to be installed.

The transgenic plant of Citrus species (Citrus aurantium L.) was constructed with a fatty acid desaturase gene using microprojectile bombardment transformation system. The DNA of a fatty acid desaturase gene, fad7, constructed in pBI121 was coated onto tungsten particles ($1.1{\mu}m$) and introduced into callus cells by bombarding with 1100 psi of helium pressure, 1/4 in of gap distance, 7.0 cm of target distance and 27 in Hg of chamber vacuum. The bombarded cells were selected on the medium containing kanamycin. The selected cells were successfully regenerated into plantlets via somatic embryogenesis on the media containing plant growth regulators. The results of polymerase chain reaction analysis of genomic DNAs from the putative transformants showed that the introduced DNAs of fad7 were present in both the selected callus cells and the regenerated plantlets.

Weather is the most influential factor for crop cultivation. Weather information for cultivated areas is necessary for growth and production forecasting of agricultural crops. However, there are limitations in the meteorological observations in cultivated areas because weather equipment is not installed. This study tested methods of predicting the daily mean temperature in onion fields using geostatistical models. Three models were considered: inverse distance weight method, generalized additive model, and Bayesian spatial linear model. Data were collected from the AWS (automatic weather system), ASOS (automated synoptic observing system), and an agricultural weather station between 2013 and 2016. To evaluate the prediction performance, data from AWS and ASOS were used as the modeling data, and data from the agricultural weather station were used as the validation data. It was found that the Bayesian spatial linear regression performed better than other models. Consequently, high-resolution maps of the daily mean temperature of Jeonnam were generated using all observed weather information.

이동통신의 발전과 인터넷의 대중화에 힘입어 무선인터넷이 등장하였고, 차세대 유무선 통신망은 IP기반으로 통합 발전될 것이라고 기대하고 있다. 이러한 배경에서 Mobile IP가 등장하였고, 현재 문제점이 많은 기본적인 Mobile IP에 기존의 하위계층에서 사용하던 여러 가지 기술들을 추가하려고 노력하고 있다. 그 중 대표적인 것이 위치등록과 페이징 기법이라고 할 수 있는데, 본 논문은 3계층에서의 이동성 프로토콜인 Mobile IP에 기존의 2계층에서의 거리기반 위치등록 방법을 적용시켜 IP망에서의 효율적인 페이징 방안을 제시하였다. 그리고, 네트워크 시뮬레이션 도구인 OPNET을 이용하여 제시한 방안을 구현하고 검증하였다.

Three economic marine algae that have been used as food and carrageenan sources were collected from Korea during a survey of marine algal flora. They share the generic features of Hypnea, and three major clades supported by the sectional features were confirmed in a phylogenetic tree based on rbcL sequences. The first species, which belongs to a species group corresponding to the sect. Spinuligerae, nests in the same clade with Hypnea yamadae in a genetic distance of 0%. It is morphologically characterized by an entangled base, subcompressed or subterete to terete axes, somewhat percurrent main axis, irregularly alternately branching with wide angle, and rarely hooked spinous branchlets. The second one is also referred to the sect. Spinuligerae and formed the same clade as Hypnea cenomyce. The genetic distance between both sequences was calculated as 0.0-0.1%, which is considered to be intraspecific. This species is distinct by somewhat entangled thallus at the basal part, percurrent axis, short spine-like branchlets densely covering the axis, and medullary lenticular thickenings. The third alga, which forms a species group corresponding to the sect. Pulvinatae, nests in the same clade as Hypnea nidulans (no intraspecific divergence). It shows occasionally epiphytic habitat rather than epilithic habitat of low mat-forming growth and percurrent erect main axes with dense lateral branchlets. Based on these morphological and molecular data, the three Korean species are identified as H. yamadae, H. cenomyce, and H. nidulans. This is the first record of the Hypnea species in Korea.
