Examining the experiences of different generations, this study assesses the subjective well-being(SWB) from eudaemonic perspective. Data was drawn from a survey of 1,214 adults in Korea. This research conducted descriptive statistics and multivariate regression analysis. Results show that even assessed from eudaemonic approach, material factors are still essential in explaining the variation of SWB. People in industrialization generation are less happy than other generations. Satisfaction with family and different types of social participation activities are related to SWB. This study suggests needs for focused attention on the factors affecting SWB in each generation.

Heterogeneous network technology is expected to be a core technology for 5G mobile communications. 5G mobile network would be composed of many base stations even have mobility, then the operator should connect base stations through the wireless backhaul technology. This paper presents Ultra Wide Area Wireless Backhaul Network System with massive array antenna. We conducted link budget analysis for Ultra Wide Area Wireless Backhaul Network and performance analysis of massive array antenna system through the transmission simulator based on beamforming technology. In wide area ($10km^2$) wireless backhaul system composed of massive antenna, we achieved 5 bps/Hz average spectral efficiency with 1 W transmission power per beam.

ICT convergence using smart livestock is that in the first-generation dairy smart farm model, each device made by several manufacturers uses its own communication method, limiting the mutual operation of each device. This study uses a model based on open control technology to secure interoperability of existing ICT devices and to manage data efficiently. The open integrated control derived from this process is the software interface structure of Open API. It is an observer that serves as real-time data collection according to the communication method of ICT devices and sensors located at each end. It consists of a broker that connects and transmits to the upper integrated management server. As a result of the performance analysis through verification of two first-generation dairy smart farm model sites, the average daily milk production increased compared to the previous year (farm A 5.13%, farm B 1.33%, p<0.05). Cow days open (DO) was reduced by 17.5% on farm A and 13.3% for farm B(p<0.05). Cows require an adaptation period after the introduction of the ICT device, but if continuous effects are observed, the effect of production can be expected to increase gradually.

Seasonal occurrences of three Tortricinae species were monitored at persimmon orchard in Changwon city ($35^{\circ}$09'18.16"N $128^{\circ}$34'43.63"E), Gyeongnam, Korea, by using sex attractant traps in 2012 and 2013. The two years of monitoring revealed that Adoxophyes honmai and Homona magnanima occurred four times a year, and Neocalyptis angustilineata did three times. Peak occurrence of A. honmai was recorded in mid-May, from early to mid-July, from late July to early August, and from mid- to late September for the generation, respectively. H. magnanima population peaked during mid- to late May, mid-July, from late August to early September, and from late September to mid-October for the generation, respectively. N. angustilineata showed three clear peaks from late May to early June, in late July, and from early to mid-September for the first, second, and third generation, respectively.

본 글은 1999년 5월 CASA/SME Blue Book에 Jim Jordan 그리고 Fred Michel이 “Next Generation Manufacturing”라는 제목으로 게재한 자료를 편자의 의도에 따라 재편집한 것입니다. CASA(Computer and Automated Systems Association)는 SME(Society of Manufacturing Engineers)에서 활동하고 있는 하나의 분과로서 CIM Enterprise Wheel을 만들어 내 유명한 곳이기도 합니다. 저자는 본 글에서 앞으로 10여년 간 펼쳐질 차세대 제조 시스템에서는 지식경영이 가장 중요한 요소라고 정의하고 있습니다. 그리고 차세대 제조 시스템의 운영전략으로는 기업통합, 인간자원의 지적이용, 지식의 개발 및 유지, NGM 프로세스 장비 및 기술의 채용을 들고 있습니다.

차세대 ULSI 소자의 다층금속배선을 위한 저유전 물질중에서, 기존의 절연막인 TEOS-$SiO_2$ 증착 장비 및 공정을 최대한 이용할 수 있으며, 물성 또한 TEOS oxide와 유사하다는 점에서 적용 시점을 앞당길 수 있는 SiOF 박막과 SiOC 박막의 특성에 대해 고찰해 보았다. 1세대 저유전 물질이라 할 수 있는 SiOF는 후속공정에도 안정적인 상태의 박막을 얻기 위해서는 3.0이하의 유전상수를 얻는 것이 불가능한 반면, SiOC는 3.0 이하의 유전상수를 가지는 안정적인 박막을 얻을 수 있다. SiOC 물질은 저밀도의 단일물질로서, 물질 내부에 후속공정에 영향을 미칠만한 기공을 포함하지 않기 때문에 후속 CMP 공정에 적합하였으며, $450^{\circ}C$이하의 열 공정에서도 응력변화 및 박막성분 탈착이 거의 일어나지 않는 점 또한 SiOC 박막의 우수한 후속공정 적합성을 보여주는 결과였다. 이러한 결과를 종합하여 볼 때, 현재 사용되고 있는 1세대 저유전 물질인 SiOF 박막을 대체할 차세대 저유전 물질로 SiOC 물질이 유망하며, 이는 3.0 이하의 유전상수를 요구하는 Gb DRAM 소자나 보다 빠른 동작속도가 생명인 논리회로(logic circuit) 소자에 적용될 경우 큰 소자특성 개선이 기대된다.

Selections for rapid and slow walking behavior were carried out with the populations, drived from Oregon-R and lethal free strain of Drosophila melanogaster. The behavior was measured by means of connected test-tube apparatus. The populations responded effectively to the artificial selection, and it reached the selection plateau after 7 generations. The realized heritability for the first 10 generations was estimated to be about $9\\sim14%$ for the rapid walking behavior, and those for slow walking behavior was about $11\\sim16%$. The results of hybridization analysis between selected populations at generations 8 and 10 indicated that some polygenes showing a slow walking behavior were partially dominant over polygenes controlled rapid trait. The populations selected for rapid and slow walking behavior were relaxed after 10 generations of selection. The response to natural selection of rapid population was completely returned to their neutral states after only 5 generations. Such phenomena would be explained by the genetic homeostasis resulted from an action of natural selection. However, the slow population did not make any difference from walking scores of their original artificial selection. It seems reasonable to assume that the slow walking behavior was possibly controlled by a major gene.
