실리콘 코팅한 복합막을 이용하여 톨로엔이나 메탄올 같은 휘발성 유기화합물의 제거 및 회수에 관한 연구를 수행하였다. 사용된 막은 코팅층의 두께가 얇고(~1μm), 지지층의 기고율이 커서 투과저항은 적었으며 코팅층과 지지층은 플라즈마 중합에 의해 결합되어 있어서 높은 압력에도 견딜 수 있었다. Feed의 유속은 60cc/min. 이하일 때 사용된 모듈에 위해 휘발성 유기화합물의 제거율은 96~99%이었으며, feed의 농도가 높을수록 제거율은 더 증가하였다. 이 공정은 휘발성 유기화합물의 농도가 높고 유속이 낮은 흐름을 처리하는데 아주 적합함을 알 수 있었다. 사용된 막을 통한 휘발성 유기 화합물들의 투과도는 4~30 × 10-9gmol/sec · cm2· cmHg 이었고, 질소의 투과도는 3~9 × 10-10gmol/sec · cm2 · cmHg 의 범위에 있었다. 휘발성 유기화합물과 질소의 선택도는 유속과 휘발성 유기화합물의 농도에 따라 톨루엔/질소의 경우 10~55, 메탄올/질소의 경우 15~125의 값을 얻었다.

Purpose: Recently, Korean cosmetics distribution market has been reorganized with the H&B store. In the domestic cosmetics distribution market, existing brand road shops are decreasing, and multi-shops are leading the H & B stores, which have greatly improved their experience and content. In these environmental changes, the offline distribution channels are turning into the multi-editing shops that have introduced products of various brands and greatly enhanced experiences and contents. Nevertheless, most studies of factors and measurement items for measuring customer experience in the H&B store use Schmitt (1999)'s Strategic Experience Modules (SEMs). Therefore, the purpose of this study is to propose a measure that is practicable through consideration of the in-store customer experience components of the H&B store. Research design, data and methodology: Based on Schmitt's Strategic Experience Modules (SEMs), which are widely used in customer experience marketing, the metric pool was constructed through customer and literature research on H & B store managers. Since then, 101 preliminary surveys and 211 main surveys have been conducted in order to propose a dimension of customer experience and refine the metrics. Results: As a result of the research, H&B store's customer experience was derived from a measurement model consisting of 19 measurement items in total of five dimensions: environmental experience, intellectual experience, behavioral experience, tech experience, and relationship experience. This study analyzed that compared to the existing Schmitt's Strategic Experience Modules (SEMs), (1) emotional experience expanded to environmental experience, (2) Cognitive and relationship experiences are maintained (3) behavioral experience was subdivided into physical and technical experiences. In particular, the environmental experience has been proposed as a major component is an important point because the H&B store recently opened a large flagship store and is competitive in constructing a differentiated space. Conclusions: Related experience was seen as an important component of customer experience in the offline store, but in the process of refining the scale, interaction items with employees of the H&B store were removed, and rather, participation in the APP or SNS channel of the company, event Participation, interaction with other customers, etc. appear to be important, while suggesting the practical implications.

There has been a recent increase in the interest towards founding companies and in line with the South Korean Government’s policy on start-up support, discussions are rife about the effect of entrepreneurship on the management and performances of these companies. To enhance the competitiveness of SMEs, it is expedient to acquire and deploy consistent entrepreneurship, differentiate corporate resources, ensure the appropriate utilization of resources and the integration of such factors in response to the changing environment. This research examines relationships among entrepreneurship, three components of corporate capabilities, dynamic capability and technical performance based on resource-based view and the dynamic capability theory. The authors also investigate the moderating role of corporate life cycle. To test the hypothesis, we conducted a survey on 352 technologies –innovative SMEs located in South Korea via professional research institutes. The findings confirm the hypothesis that SMEs’ entrepreneurship has a positive effect on three kinds of corporate capabilities (e.g., marketing, R&D, operations capability), and it had a positive effect on dynamic capability, whiles dynamic capability also had an influence on technical performances. The findings also confirmed the hypothesis that corporate life cycle moderates the relationship between dynamic capability and technical performances respectively. The research implications for both practitioners and academicians are discussed.

This paper reexamines the interannual intensity change of tropical cyclone (TC) over the western North Pacific. Analyses are done for the annual extreme intensity and the average intensity of the five strongest typhoons based on the best track data issued from the RSMC (Regional Specialized Meteorological Center) Tokyo and the JTWC (Joint Typhoon Warning Center). Trends over the last 30+ years in one data set are nearly opposite in another. Specifically, the TC intensity tends to increase with the years in the JTWC data, whereas the opposite is found in the RSMC data. Realizing that one data set shows a significant statistical difference from the other, a homogenization process has been applied to the original data so that comparisons of the two data sets and the trend analyses become more meaningful than those with solely the original data. With the homogenized data, we present some cautious conclusions regarding the TC intensity changes over the western North Pacific. The annual extreme TC intensity has been decreasing, while the strong TCs have become stronger over the years. For TCs entering the KMA emergency area and directly hitting Korea, we are hesitant to make any conclusions because the corresponding area is small so that the number of TCs entering the area each year is too small to have any statistically significant implications.

This study recognized five annual cycle modes of the tropical cyclone (TC) activity in the western North Pacific using the CMA-STI data by an objective-oriented K-means cluster analysis approach. The five annual cycle modes include one normal mode and four abnormal modes: a weakened mode, two enhanced modes, and an anti-seasonal mode which suggests TC activities are enhanced in early season but suppressed in peak season. The yearly storm number and storm lifespan of both the weakened mode and the anti-seasonal mode are different from those of the two enhanced modes. The annual amplitudes of TC activity seem to be closely associated with the area of TC genesis. The discrepancies are obvious in frequencies of the five modes. However, comparison with both JMA and JTWC data suggests that the seasonality of TC activity has large bias.

Objectives Here, we report the effect of overexpression of ginseng farnesyl diphosphate synthase on the transcription of three key regulatory enzymes involved in triterpene metabolism in hairy root of ginseng and Centella asiatica (L.) Urban. Materials and Methods A four-year-old root of Panax ginseng C.A. Meyer and Centella asiatica (L.) Urban whole plants were obtained from National Institute of Crop Science (Suwon, Korea) and Chonnam National University (Gwangju, Korea), respectively. Agrobacterium rhizogenes R1000 strain was kindly provided by Dr. In (Nongwoo Bio, Yeju, Korea). Results and Discussion The role of farnesyl diphosphate synthase (FPS) in triterpene biosynthesis (Fig. 1) was investigated. A pCAMBIA3101 vector was used to insert a exogenous gene into target plant genome (Fig. 2). After the transformation, we produced Panax ginseng and Centella asiatica hairy roots by introducing the coding region of the gene from Panax ginseng. In these hairy roots, integration of the transgenes into the C. asiatica nuclear genome was confirmed by PCR analysis using PgFPS (P. ginseng FPS) primers and by Southern hybridization using PgFPS-specific probe. FPS specific activity is increased 4-fold compared to controls. In RT-PCR analysis, overexpression of PgFPS in hairy roots was observed (Fig. 3) and two genes, cycloartenol and beta-amyrin synthase, related to triterpene biosynthesis were up-regulated. These results suggest that FPS overexpression might lead to an enhanced biosynthesis of triterpene saponins and phytosterols. However, we did not demonstrate whether or not the introduction of PgFPS gene in Centella asiatica genome directly enhances triterpene saponin production, although our results showed that gene expression related to triterpene saponin biosynthesis were obviously up-regulated. Therefore, additional experiments such as overexpression of FPS gene in triterpene saponin-deficient mutant plants will be required.
