The Commercial space are changed gradually large scalized and complexed to introduce different culture exchanges and experience. However, the mass-complex commercial space are limited as of their complexed space composition or degree of space depth, which may become factors causing people to get tired easily. Thus, having a design strategy is important to create economical effectiveness in order to overcome these limitations and for the people to stay longer and do their consumption activities through more experiences and social interchanges. Recently, Jerde Partnership's who designed many complex commercial spaces made a commercial success by their unique design strategy to setup a new space and lead the interaction between space and people. The purpose of this study is based on Jerd's design concept to analyze Jerd Partnership's design strategy and space related structure to propose their space construction and design method for mass-complex commercial spaces. The results are as follows. (1)Jerde Partnership's causes the abundant space experience of the user through mass and space constitution to have a theme and a story. (2)They builds an excursion type line of flow system with an organic curve, and a non-daily experience by the change of the space scale and the application of various programs is enabled and guides the stay for the long time. (3)They builds the doorway of various courses and a circulation system through the open space and controls depth of the space. In addition, various events are performed in the center of such a circulation system, and this event makes a unique place.

Purpose: sexual permissiveness, sexual behaviors and the consumption of mass media in female high school students. Methods: 306 students, from three different girls' high schools in Seoul, who understood the purpose of the study, participated as subjects in the research. The research tools were the mass-media consumption scale, the sexual attitudes survey, the sexual permissiveness survey, and the sexual behaviors scale. The data were analyzed using descriptive analysis, t-test, ANOVA with SPSS/WIN. 18.0 program. Results: The subjects' daily mass media consumption was 143.7 minutes of TV watching on weekdays, while 253.9 minutes on weekends, 88.5 minutes of Internet surfing, 57.8 minutes of listening to pop music. Watching TV music programs was 68.3 minutes a week. Watching TV 'alone' was 30.7% and Internet surfing in one's 'own room' was the highest at 39.9%. The average score of sexual attitudes, sexual permissiveness, and sexual behaviors was 25.7/55, 35.4/64 and 0.7/10, respectively. Sexual attitudes and sexual permissiveness varied according to how much time they spent surfing the Internet, with whom they watched TV, and how much time they spent listening to popular music; and sexual behavior differed according to the time spent on the Internet. Conclusion: Educational programs need to be developed to help young people control their media consumption behaviors. In addition, political attention and a proper system are needed to promote a healthier and sounder pop culture through a public review system.

Field and nutrient cultures of American ginseng (Panax quinquefolius L.) were used to establish foliar symptoms related to boron (B) concentration in leaves and soils, and to evaluate radish as a time-saving model system for B nutrition. Application of excess B, 8 kg/ha versus the recommended 1.5 kg/ha, to field plantings of 2-, 3-, and 4-yr-old American ginseng plants just prior to crop emergence caused, within 4 wk after crop emergence, leaf symptoms of chlorosis followed by necrosis starting at the tips and progressing along the margins. The B concentration in leaves of 2-4-yr-old plants receiving 1.5 kg/ha Bwas $30{\mu}g/g$ dry mass compared to $460{\mu}g/g$ dry mass where 8 kg/ha B was applied. Similarly, B concentration in soils receiving the lower B concentration was 1.8 mg/g dry mass and $2.2-2.8{\mu}g/g$ dry mass where the higher B concentration was applied. Application of 8 kg/ha B reduced the dry yield of 3rd-yr roots by 20% from 2745 kg/ha to 2196 kg/ha and 4th-yr roots by 26% from 4130 kg/ha to 3071 kg/ha. Ginseng seedlings and radish were grown under greenhouse conditions in nutrient culture with four B concentrations ranging from 0 mg/L to 10 mg/L. At 5 mg/L and 10 mg/L ginseng and radish developed typical leaf B toxicity symptoms similar to those described above for field-grown plants. Increasing B in the nutrient solution from 0.5 mg/L to 10 mg/L decreased, in a linear fashion, the root and leaf dry mass of ginseng, but not radish. Given the many similarities of ginseng and radish to B utilization, radish might be used as a timesaving model system for the study of B, and other micronutrients, in the slow-growing perennial ginseng.

It has been appeared since 1979 that the pattern of laver culture changes from household management to entrepreneurial management. The typical entrepreneurial laver culture management (ELCM) can be defined as a management by the floating aquaculturing method and mechanical processing system. Historical studies show that the ELCM could be operated only under the following condintions; \circled1 securing capital, labor and aquaculturing farm. \circled2 Leveling up of technology to combine these resources effectively. \circled3 Realizing its true value of products for good profits. In turning from household mangement to ELCM, there are some obstacles as follows ; \circled1 Uncertainty, which cannot maintein the merit of mass production because the object of laver culture is living in the sea. \circled2 Immaturity of management owing manly to the lower level of technology and scarcity of competent managers. \circled3 Social problems ; lack of aquaculturing farm, overpopulation in fishing villiage, side-job with agriculture etc. For these reasons, there has been household management with overlabor and underconsumption in fishing village. In order that ELCM can enter the stage of maturity, those problems should be solved. Because ef laver industrial inferiority, these can be solved by the support assistance of government. As the required conditions in ELCM are filled by the government policy, ELCM are increased recently in its numbers.

The uniqueness of the K-Pop 'idol' culture, which is a key area of its success, can be found not only through the acceptance of diverse cultures and the strengthening of the performance capacity, but also by the effective utilization of new technological environment. As a result, the Korean idol system, which is distinguished from the Japanese idol system, is established. And these systems are evolving with new technological environments. This paper examines the process of evolution of the Korean idol system that adapts to the technical environment through the case of the idol girl group 'IZ*ONE'. 'IZ*ONE' not only achieved rapid success by actively utilizing SNS and new media and producing interactive narratives, but also establishing stable expansion and homogeneity of fandom through interactive rituals. By comparing the evolution and achievement of such a system with the Japanese idol system, we will be able to present the factors of K-Pop success more clearly.

In an attempt to establish the mass proliferation system, Eucalyptus pellita, a 5-year-old plus tree, was cultured with three different culture types in 1L vessels: solid culture without ventilation (conventional culture), liquid culture without ventilation and open-type liquid culture with forced ventilation. Then the culture scale was subsequently increased from 1L to 10L in vessel volume. After 4 weeks of 1L-scale culture, the best growth was obtained by culturing plantlets on open-type liquid culture, suggesting that the in vitro plantlets growth can be enhanced by liquid medium and ventilation. In open-type large scale culture in 10L vessel, plantlets growth resulted in a 370% increase in the number of nodes, 3.6 times increase in leaf expansion, and 3.3 times increase in shoot length, while the conventional culture suppressed shoot growth due to the callusing on the leaves and lack of $CO_2$. The results indicated that the open-type large scale culture system was effective for enhancing productivity by improving growth of the plantlets in clonally proliferated plus tree, Eucalyptus pellita.

This study was to examine expression of the recombinant full-length adiponectin (recombinant adiponectin) in insect ovarian cell culture system and to characterize structural properties of the recombinant adiponectin secreted in medium. Gene construct encoding the recombinant adiponectin contained N-terminal collagen-like domain (110 Amino Acids, AAs), C-terminal globular domain (137 AAs) and C-terminal peptides for detection with V5 antibody (26 AAs included adaptor peptide) and purification using the 6xHis tag (6 AAs). The approximate molecular weight of the product (monomer) was 35 kDa. Molecular mass species of the expressed recombinant adiponectin were monomer (~35 kDa), dimer (~70 kDa), trimer (~105 kDa) and hexamer (~210 kDa). The major secreted species were the LMW forms, such as monomer, dimer, and trimer. There was MMW of hexamer as minor form. HMW multimers (~300 kDa) were shown as a tracer or not detected on the SDS-PAGE in several experiments (data not shown). The multimer forms in this study were not compatible to those in animal or human serum and adipose tissue by other researcher's study in which the major multimer forms were HMW. By protein denaturing experiments with reducing reagent (${\beta}$-MeOH), anionic detergent (SDS) and heat ($95^{\circ}C$) on the SDS-PAGE, not all adiponectin multimers seemed to have disulfide bond linked structure to form multimers. The recombinant adiponectin which expressed in insect ovarian cell culture system seemed to have the limitation as full physiological regulator for the application to animal and human study.

This paper proposes the method of exactly identifying both viscous and friction damping from free vibration response to SDOF structure. Both displacement and acceleration free vibration responses to SDOF system, in which both viscous and friction damping are considered as its damping mechanism, are discussed to verify the proposed method. The relationship for identifying both viscous and friction damping is derived from two consecutive amplitudes of displacement or acceleration peak response. The proposed method is verified through the numerical simulation for an assumed SDOF system consisting of mass, both viscous and friction damping and spring components.

RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) is the most important explosive contaminant, both in concentration and in frequency, at military shooting ranges in which green technologies such as phytoremediation or constructed wetlands are the best option for mitigation of explosive compounds discharge to the environment. A study was conducted with two identical lab-scale plug flow constructed wetlands planted with Amur silver grass to treat water artificially contaminated with 40 mg/L of toxic explosive compound, RDX. The reactor was inoculated with or without RDX degrading mixed culture to evaluate plant-microorganism interactions in RDX removal, transformation products distribution, and kinetic constants. RDX and its metabolites in water, plant, and sediment were analyzed by HPLC to determine mass balance and kinetic constants. After 30 days of operation, the reactor reached steady-state at which more than 99% of RDX was removed with or without the mixed culture inoculation. The major transformation product was TNX (Trinitroso-RDX) that comprised approximately 50% in the mass balance of both reactors. It was also the major compound in the plant root and shoot system. Acute toxicity analysis of the water samples showed more than 30% of toxicity reduction in the effluent than that of influent containing 40 mg/L of RDX. In the Amur silver grass mesocosm seeded with the mixed culture, the specific RDX removal rate, that is 1st order removal rate normalized to plant fresh weight, was estimated to be 0.84 kg⁻¹ day⁻¹ which is 16.7% higher than that in the planted only mesocosm. Therefore, the results of this study proved that Amur silver grass is an effective plant for RDX removal in constructed wetlands and the efficiency can be increased even more when applied with RDX degrading microbial consortia.
