This study was conducted to develop economical agricultural fertilizer media for the mass culturing of Nannochloropsis oceanica. Specific growth rates of N. oceanica cultured with differing concentrations of commercial compounds, urea fertilizers, and trace elements (Zn, Cu, Co, Mo) were compared with the growth rate in f/2 medium. Among the various added trace elements, $CuSO_4{\cdot}5H_2O$ was most effective for high growth of N. oceanica. The main nitrogen source in the agricultural fertilizers was ammonium, which was unsuitable for the growth of N. oceanica. Thus, the fertilizer at a lower concentration infused with $NaNO_3$ as a nitrogen source was more effective than fertilizer at higher concentrations. In this study, the growth of N. oceanica cultured with an agricultural fertilizer medium composed of compound fertilizer (41.7 mg/L), urea fertilizer (34.4 mg/L), $NaNO_3$ (150 mg/L), and $CuSO_4{\cdot}5H_2O$ (0.0588 mg/L) was similar to that of N. oceanica cultured in f/2 medium.

Preeminent water treatment plans are essential to preserve the water quality of aquatic biotopes. Previous studies have not been sufficient to provide cost-effective maintenance method since they focused only on the purification of deteriorated water that requires a continuous supply of clean water. This study proposes an economical method of water quality maintenance using water treatment media block constructed vertically using porous ceramics, zeolite, and river pebble. The water treatment media block does not require a separate purification area because it functions as a purifier within the ecological pond which can maximize the biotope area. To evaluate the performance of the water treatment media block, we longitudinally tracked the change of water quality indicators (pH, TDS, COND, DO, T-P, T-N, COD) suggested by Water Environment Standards, Ministry of Environment, Republic of Korea. We compared the water quality of one control (A: general ecological pond composition method of the laminated structure) and two experimental groups (B: a combination of aquatic plants and a water treatment media block, C: a water treatment media block only). As a result, we confirmed that the water treatment media block is an efficient and economical method to maintaining the water quality of the ecological pond for a long time. The water treatment media block will be a great help in providing a better aquatic biotope space for aquatic insects and fishes living in clear water.

The purpose of this study was to investigate the actual state and problems of outlet stores. And examine store attributes shopping orientations information sources according to demographic characteristics for outlet store patronage group. The questionnaires were administered to 400 women living in Taegu. The data were analyzed by using Frequency Percentage Factor Analysis MANOVA. The results of the study were as follows; 1) Outlet stores in Taegu area were run as the type of agency and dealt in most brands of their own companies, There were plenty of as-sortment and merchandise. The discount rate was 50-60% Stores' locations were scattered which made shopping environment incon-venient. 2) The store attributes were composed of five factors such as fashion & products diver-sity service store reputation convenience and price. Shopping orientation were com-posed of six factors such as self-confidence for shopping brand oriented store loyalty & near-store oriented economical self-assumed shopping and difficulty of choice. Information sources were composed of four factors such as print media & display personal information advertising and store visit. 3) There were significant differences be-tween patronage group and non-patronage group in store reputation service fashion & products diversity. Patronage group is more satisfied with these three factors. There were significant differences between patronage group and non-patronage group in brand oriented and economical Non-patronage group was more brand oriented and patronage group was more economical. There were significant difference between patronage group and non-patronage group in print dedia & display factos. Non-patronage group made more use of print media& display than patronage group as information sources. There were significant differences between patronage group non-patrpnage group in age marital status and levle of education.

In order to develop a method of economical production and to reduce energy-consumption in fuel alcohol production, we investigated the fermentation characters of two newly selected thermotolerant yeasts. The RA-74-2 showed stable and superior fermentability between 30 and $40^{\circ}C$ in 20% glucose media in comparison to the industrial strains. The optimum concentration of glucose for economical fermentation at $40^{\circ}C$ was 15-18%, and organic nitrogen was necessary for a satisfactory fermentation. The optimum pH was 4.0 and aeration was adversed for high temperature fermentation. Agitation was an important factor at $40^{\circ}C$ and the addition of magnesium ion 0.2% was required in this experiment. When the inoculum was increased, ethanol productivity as well as the speed of fermentation increased. On the other hand RA-912, which can grow at $48^{\circ}C$, showed similar fermentability between 30-$45^{\circ}C$ in 20% glucose media As the concentration of substrate decreased, fermentation ratio increased at $45^{\circ}C$ (45%, 65%, 95% fermentation ratio in 20%, 15%, 10% glucose media, respectively). Also, requirement of organic nitrogen and magnesium ion in RA-912 was similar in RA-74-2. The optimum pH for fermentation was 5.0, and the effects of agitation were enhanced at $37^{\circ}C$ than at $45^{\circ}C$. As the inoculum was increased, fermentation speed became more enhanced but the ethanol productivity was less affected. RA-912 showed fermentability with various substrates. Among the substrates used, inulin was the most promising substrate for the high-temperature fermentation. When 14.5% inulin was used as the substrate, 93% and 55% fermentation ratios were shown at $37^{\circ}C$ and $45^{\circ}C$, respectively.

This study attempts to fiugure out how residents differentially perceive the storage according to the housing types and sizes. The major findings are as follows: 1) The residents in the tenement house dissatisfy the storage space more than those in the detached house. 2) It is the arrangement that is considered as the most important factor while storaging. 3) It is non-daily goods that is the most difficult item to store. 4) Most information about storage is obtained form mass media.

소셜네트워크 시대가 도래하였다. 소셜미디어는 자신의 생각이나 의견, 경험 등을 서로 공유하고 참여하기 위해 개방된 미디어를 뜻한다. 이러한 소셜미디어는 기존의 미디어를 대체할만큼 위협적이며, 새로운 소통도구로서도 각광을 받고 있다. 글로벌 시대에서는 국가이미지가 국가의 새로운 경쟁력의 원천으로 인식되고 있다. 이에 본 연구에서는 소셜미디어의 활용수준이 국가이미지에 어떠한 영향을 미치는가를 분석하고자 하며, 소셜미디어의 활용수준을 활용량과 활용범위로 나누어서 분석을 하였다. 또한 국가이미지를 구성하는 요소들이 구매의도에 어떠한 영향을 주는지 분석을 하였다. 분석결과, 활용량은 국가이미지, 국민이미지, 정치이미지에 영향을 미치고 활용범위는 경제이미지, 국민이미지, 정치이미지에 유의한 영향을 미치는 것으로 나타났다.

본 논문에서는 M/W 중계 주파수의 증설 또는 신규 수용을 가급적 배제하고 필요 회선을 B-WLL 또는 광통신망으로 대체 가능성을 품질 및 경제성 측면에서 분석하였다. 품질 목표에서는 매체간 비교를 위한 전제조건 및 분석방법을 도출하였다. 그리고 E1급을 기준으로 비트오율(BER) $10^{-6}$ 을 만족하도록 기준을 설정하고, 매체별로 가용도에 대한 거리를 산출하였다. 또한 경제성 측면에서는 광통신, M/W, B-WLL 시스템의 기본 구성 단위를 기반으로 서비스 기간, 장비용량, 전송거리, 대용량 전송으로 분류하고 다양한 광전송 회선 및 B-WLL 구성에 대해 분석하였다. 목표 가용도를 99.999 %로 설정시 B-WLL로 M/W를 반경 1.6 km까지 대체 가능하다는 것을 알 수 있었다. 또한 광으로 대체할 경우, 광 관로용의 전주 임대 시에는 서비스 기간에 관계없이 M/W보다 경제성이 있으며, 광 관로 자체를 굴착할 경우에는 고려 방법 중의 어느 경우에 대해서도 경제성이 없는 것으로 판명되었다.
