The Lakhta Center is a Multifunction Complex Development (MFCD) consisting of 1) an 86 story office tower rising 462 m above the ground to provide high-end offices for Gazprom Neft and Gazprom Group affiliates 2) a Multi-Function Building (MFB) that includes, a scientific/educational center, a sport center, a children's technopark, a planetarium, a multi-transformable hall, an exhibition center, shops, restaurants, and other public facilities 3) a Stylobate 4) "The Arch, which forms the main entrance to the tower, restaurants, and cafes 5) underground parking and 6) a wide range of large public plazas. While each of the MFCD buildings is technically challenging in its own right, the focus of the paper is to present the development and integration of the structural and foundation systems of the bowed, tapered, and twisted shape of the tower into the fabric of the tallest Tower in Europe.

W3C(World Wide Web Consortium)는 2007년 상반기부터 웹 기술을 PC를 넘어 휴대폰, PDA, 정보가전, 로봇 등 모든 디바이스로 적용이 확대하기 위해 유비쿼터스 웹 응용을 위한 표준 개발을 시작하였다. 이를 담당하고 있는 유비쿼터스 웹 응용 워킹그룹은 탁상용 컴퓨터뿐 아니라 사무용품, 가정 매체 기구, 이동 전화, RFID나 바코드를 포함하는 센서나 이펙터(effector) 등의 유비쿼터스 기기들이 다양하게 흩어져 있는 환경에서 쉽게 웹 응용 개발을 가능하게 하는 표준 개발을 목표로 한다. 본 워킹그룹의 활동의 중요한 표준화 아이템 중의 하나는 Delivery Context: Client Interfaces(DCCI)로 이는 다양한 디바이스들의 기능들의 접근을 위한 표준 인터페이스를 정의하는 것이다. DCCI가 중요한 이유는 현재 웹 환경에서 오픈 API를 이용하여 개발되고 있는 다양한 매쉬업 응용에 GPS와 같은 단말을 기능을 매쉬업을 제공할 수 있는 기반이 되기 때문이다. 본 논문에서는 최근에 W3C의 UWA(Ubiquitous Web Application) WG에서 추진되고 있는 DCCI에 대한 표준화 동향을 설명한다.

In this paper, an integrated navigation system based on GPS(Global Positioning System) and Dead-Reckoning (DR) is designed. For the calibration of DR, a self-calibration method and a GPS-based calibration method are proposed. From the field-test results, it is shown that DR can be successfully calibrated by the two proposed calibration methods. Also, a cascaded filter approach and a mixed-measurement algorithm are employed for GPS/DR integration. By using the newly proposed mixed-measurement algorithm, it is shown in simulation that the position error becomes smaller than by using only DR even if the number of visible GPS satellites is less than 4.

유비쿼터스 지능공간에서 사람의 행동과 위치를 모니터링하는 것은 서비스 제공을 위해 기본적이며 필수적인 단계이다. 본 논문에서는 스마트 펜던트(SmartPendant)의 카메라 영상과 GPS위치 정보를 이용한 새로운 웨어러블 컴퓨터를 제안한다. 우선, 행동 인식를 위해 영상간에 특정 픽셀 값 차와 옵티컬 플로우를 사용하였으며, 인식이 가능한 행동으로는 걷기, 멈춤, 방향전환이다. 또한, GPS를 이용한 사용자의 위치 정보는 위도와 경도에 대한 스트링값을 패킷값으로 변환하여 지능형 상황인지 서버에 전달된다.

Purple-colored shell individuals were discovered among normal green-colored shell individuals in artificial seed of Pacific abalone, Haliotis discus hannai, reared on an ordinary type of diatom and artificial diet. In the present study, factorial mating experiments were designed to clarify the genetic control of the variant (purple type) and normal (green type) of shell color. The parental population of purple type and green type individuals were derived from a single family between a female and male of each type of coloration. The all mating families were reared in same tank for the same breed environment. The individual of 4 type families were distinguished by paternity test using microsatellite DNA. In factorial mating experiments, all individuals offspring of GG (green type female and green type male), GP (green type female and purple type male) and PG (purple type female and green type male) mating types appeared to green type. In only PP (purple type female and purple type male) mating type, all individuals offspring appeared to purple type. The results suggested that the purple shell color is controlled by recessive purple type allele and a dominant green type allele at a single locus.

Radiation-induced life shortening, carcinogenesis and other pathological changes were investigated in NIH(GP) mice after $^{60}Co-{\gamma}$ ray irradiation(100~700rads). The results were summarized as follows: 1. There were little difference in body weights, hematological examination and other clinical findings between normal and irradiated groups. 2. Mean survival time of the mice after irradiation were decreased dose-dependently. 3. Main gross findings of the mice irradiated were appeared as enlargement of spleen, thymus and lymph nodes, tumorous nodules of lung and cyst of ovary. Especially, enlargement of thymus was promineort in high dose group. 4. Microscopically, there were various findings including myeloid leukemia, thymic lymphoma, lung adenoma, adenosquamous cell carcinoma of pancreas, pneumonia and other pathological changes. Especially thymic lymphoma was highly frequent in the 700 rads group.

Subsequent to the introduction of the "Laws on Consumption Promotion of Livestock Products" in 2002, a mandatory check-off system for the egg industry was introduced in June 2009. Unlike other livestock products, the check-off on eggs is financed not from the sale of the egg-the end product-but from the spent hen. Variables such as the falling price of spent hens lead to a low financing rate; The present farm allotment rate of 14%, introduced in 2015, is much higher than the 0.2% to 0.3% check-off rate in other types of business, thus placing a huge burden on farms. When check-off is financed from the egg, it is expected that 6.5 billion won will be raised using a rate of 0.3% of sale proceeds, Therefore, it is urgent for the government to establish infrastructure to enable producers and merchants to do business through Grade & Packing centers. This can be achieved by the staged construction of local Grade & Packing centers. Check-off should continue to be financed from the present spent hen until this infrastructure is established, and an institutional strategy should be provided by the government to raise the financing rate accurately and transparently using statistical treatment of supply data for spent hens as a short-term alternative.

The molecular size reduction and the formation of bitterness during a tryptic hydrolysis of soybean 11S glycinin were determined by using quantitative analysis and organoleptic evaluation. The 11S glycinin of 90% purity was prepared by cryoprecipitation and Con A Sepharose 4B affinity chromatography, and hydrolyzed with trypsin in a pH-stat reactor for 4 h. Bitterness was formed within 1 h of hydrolysis, and then slowly increased up to $3.5\times10^{-5}$ M quinine-HCl equivalent. The extent of hydrolysis (DH) was 7% at 1 h and increased up to 12% by the end of the reaction. The -amino nitrogen content increased from an initial 0.7 mM to 7 mM at the end of the period. The SDS-PAGE analysis showed that the acidic subunit of 11S glycinin was mostly hydrolyzed. The GP-HPLC analysis indicated that the bitterness was mainly contributed by the peptide fractions of molecular weights of 360-2,100 Da.

To get the highly-accurate and precise position of a GPS receiver, they should consider the state-of-the-art GPS force and measurement models. Especially, the phase center variations (PCV) of a GPS antenna can cause several centimeters of positioning errors in the vertical direction. In this study, we implemented four different models of PCV and evaluated their impact on the computed coordinates. The test data were taken from the 14 National Geography Information Institute permanent GPS stations and 30 Minisry of Government Administration and Home Affairs sites. For different combinations of calibration methods, an average of 1.3-2.6cm of height difference was observed. Also, we found a maximum error of ${\sim}4mm$ in the estimates of the precipitable water vapors.

이 논문에서는 소포 배달 서비스를 위한 인텔리전트 모니터링 시스템(Intelligent Monitoring and Control System; IMCS)에 대해 기술한다. IMCS 는 GIS, GPS 그리고 무선 통신 기술을 이용하여 택배의 접수와 배달 업무를 효율적이고 효과적으로 개발하기 위한 시스템이다. IMCS는 모두 세개의 서브 시스템으로 구성되어 있는데 접수와 배달 계획을 수립하는 PDPS(Pick-up and Delivery Planning System)과 접수/배달 현황과 차량의 위치를 파악할 수 있는 PDMS(Pick-up and Delivery Monitoring System), 그리고 개인휴대단말기(PDA)을 이용한 실시간 업무 처리 시스템인 MOCS(Mobile Operations and Communication System)으로 구성되어 있다. PDPS는 GIS와 최적화 알고리즘을 이용하여 접수와 배달을 위한 방문 순서와 경로 그리고 고객에게 방문할 예정시간 등을 생성한다. MOCS에서는 GPS와 무선 통신을 이용하여 업무 중 발생한 접수/배달 결과와 위치 정보를 실시간으로 PDMS에 전송하고 바코드 스캐닝과 전자 서명 등의 업무를 지원한다. PDMS에서는 수신한 정보에 따라 소포의 접수/배달 현황과 차량의 위치를 전자지도 상에 표현하고 업무 차량의 이동 궤적을 표시하여 계획된 경로와 비교하여 모니터링하고 관제할 수 있다. 현재 IMCS는 국내 한 우체국에서 시범 운영되고 있다.
