The purposes of this study were to analyze the formative relationship between Surrealistic clothes and hat with the focus on the period from the 1990's to 2008 and to find out the development direction of next hat design. The method to analyze the relationship between clothes and hats was the formative analysis by Marian L. Davis and Marilyn R. Delong. Hat design of surrealism was cylindrical or tear drop in a shape according to the principle of $D{\acute{e}}paysement$ and Trompe l'oeil, and was similar with the Form of a jacket, a sleeve, or a skirt. In color, accent color coordination mainly appeared and sometimes contrast color coordination induced illusion effect. In material, a variety of materials were used according to the principle of $D{\acute{e}}paysement$ and Trompe l'oeil, and contrast was widely used like color. In Decoration, the decoration or pattern of clothes was intactly applied to hats. The results suggest that clothes and hat have an organic relationship, and a hat style is changed with formative elements of clothes.

The study is to identify the factors influencing Chinese consumers' intentions to purchase organic food based on Theory of Planned Behavior (TPB) model. This research concentrates on the moderating effect of gender during the process. An offline investigation was used for the research purpose. Data for the study was gathered from February to March 2018. The total of 260 valid responses was used for this analysis. An online questionnaire was distributed through Email to Chinese consumers living in major cities of China and abroad to collect the data. Multi group analysis and model comparison were conducted to examine the moderating effect of gender. Our results support previous researches suggesting that gender moderates the relationship between attitude and behavioral intention. However, surprisingly, no significant moderating effect of gender on the relationship between subjective norms and behavioral intention was found. This paper revisited TPB antecedents and the moderating effect of gender focusing on Chinese organic food markets. The findings provide essential managerial implications to the marketers in this industry. Further research could examine whether TPB model can be applied to other potential purchasing groups.

The present study investigates the effect of oxidation-reduction potential (ORP) and organic compounds on specific anaerobic ammonium oxidation activity (SAA) using batch experiments. The batch tests were based on the measurement of nitrogen gas production. The relationship between ORP and dissolved oxygen (DO) concentration was found to be ORP (mV) = 160.38 + 68 log [$O_2$], where [$O_2$] is the DO concentration in mg/L. The linear relationship obtained between ORP and SAA ($R^2$ = 0.99) clearly demonstrated that ORP can be employed as an operational parameter in the Anammox process. At ORP value of -110 mV, the SAA was $0.272{\pm}0.03\;g\;N_2-N\;(g\;VSS)^{-1}\;d^{-1}$. The investigation also revealed inhibitory effect of glucose on the SAA while acetate concentration up to 640 mg COD/L (corresponding to 10 mM) had stimulating effect on the SAA. However, acetate concentration beyond 640 mg COD/L had inhibitory effect on the Anammox activity. The results indicated that nitrogen rich wastewaters containing low level organic matter could be better treated by Anammox microorganisms in real-world conditions after some acidification process.

In the area of artificial photosynthesis, particularly for the generation of hydrogen form water, much attention has been paid on organic-inorganic hybrid system. Most of all, a dye/TiO2-combined system has been suggested and its potential utility was well manifested. However, due to its complicated nature of charge interactions in between dye and TiO2 -interface there remains a great challenge to establish the charge-activity relationship, per se light driven charge generation and recombination kinetics with respect to the amount of hydrogen produced. Further complexity of that hybrid system has been witnessed when sacrificial donor and aqueous media are considered. To unveil the operating mechanism on such a dye/TiO2-combined system, we have prepared organic dyes suitable to account for the effect of sacrificial donor as well as water interactions, and prepared the typical dye-grafted TiO2 films to investigate charge-activity relationship. Femtosecond flash photolysis clearly defined the dye effects anchored on to the TiO2 platform. In addition, photodynamic data contemplated well to the dye orientation proposed by the DFT calculations. Recent findings provide fundamental understanding on the dye-grafted TiO2 system and establish a firm background how future dye-sensitized organic-inorganic hybrid system can be designed for the light driven hydrogen generation from water.

We fabricate organic-inorganic hybrid thin film for the purpose of encapsulation by molecular layer deposition (MLD) using Trimethylaluminium (TMA) and Adipoyl Chloride (AC). Ellipsometry was employed to verify self limiting reaction of ALD. Linear relationship between number of cycle and thickness was obtained. We found that desirable organic thin film fabrication is possible by MLD surface reaction in nanoscale. Purging was carried out after dosing of each precursor to form monolayer in each sequence. We also confirmed roughness of the organic thin film by atomic force microscopy. We deposit TMA and AC at $70^{\circ}C$ and that 1.78A root mean square was obtained which indicates that uniform organic thin film was formed. We confirmed precursor's functional group by IR spectrum. We calculated WVTR of organic-inorganic hybrid super-lattice epitaxial layer using Ca test. WVTR indicates superlattice film can be possibly use as encapsulation in flexible devices.

We fabricate encapsulation-layer of OLED panel from organic-inorganic hybrid thin film by atomic layer deposition (ALD) molecular layer deposition (MLD) using Al2O3 as ALD process and Adipoyl Chloride (AC) and 1,4-Butanediamine as MLD process. Ellipsometry was employed to verify self-limiting reaction of MLD. Linear relationship between number of cycle and thickness was obtained. By such investigation, we found that desirable organic thin film fabrication is possible by MLD surface reaction in monolayer scale. Purging was carried out after dosing of each precursor to eliminate physically adsorbed precursor with surface. We also confirmed roughness of the organic thin film by atomic force microscopy (AFM). We deposit AC and 1,4-Butanediamine at $70^{\circ}C$ and investigated surface roughness as a function of increasing thickness of organic thin film. We confirmed precursor's functional group by IR spectrum. We calculated WVTR of organic-inorganic hybrid super-lattice epitaxial layer using Ca test. WVTR indicates super-lattice film can be possibly use as encapsulation in flexible devices.

하구역은 강과 하천을 통해 육상과 해양을 연결하는 전이수역으로 해양으로 공급되는 많은 물질들은 연안환경의 일차 생산성을 결정하는 중요한 역할을 담당하며, 이러한 연안생태계는 생물량에 의해 제거되는 탄소인 블루카본의 탄소 저장소로서 기후변화를 완화시키는 역할을 한다. 우리나라의 서-남해 하구역(한강, 금강, 영산강, 섬진강, 낙동강)과 동해 용승해역에서 지난 6년간 표층퇴적물의 평균입도와 유기탄소 함량의 변화와 두 인자들 사이의 상관관계를 분석하였다. 조사기간(2015-2020년) 동안 서-남해 하구역과 동해 용승해역 표층퇴적물의 평균입도와 유기탄소 함량은 계절적 변화가 관찰되지 않았으며, 전반적으로 각 해역의 다양한 해양환경 및 수리역학적 조건에 의해 두 인자들이 조절되는 것으로 해석된다. 조사된 모든 시료채취의 동시성이 없는 문제점에도 불구하고 연구지역에서 분석된 모든 퇴적물 평균입도들의 평균값과 유기탄소 함량의 평균값은 양의 상관관계를 보이며 각 하구역과 동해 용승해역을 구분한다. 동일한 양의 상관관계를 보이는 각 하구역에서는 아마도 같은 과정에 의한 퇴적물 점토입자의 퇴적이 유기탄소 축적에 중요한 역할을 담당한다. 그러나 동해 용승해역은 하구역과 다르게 추가적인 유기탄소 축적의 요인이 나타난다. 국내 주요 하구역들이 연안환경에서 중요한 탄소저장소로서 평가되기 위해서는 탄소 저장량 계산을 위한 추가적인 자료(퇴적률, 전밀도 등)가 요구된다.

Purpose - This study focused on consumer perceptions of service quality in organic food shops, the innovativeness of organic products, and which SERVQUAL sub-dimensions increase purchase intentions. Another purpose of this study was to explore the relationship between consumer perceptions of organic food shops, their direct interest in organic food, and their purchase intentions. Research design, data, and methodology - We tested our hypothesized model within a structural equation modeling (SEM) framework, utilizing path-analysis implementation. The AMOS 18.0 software was used, and we found that it fit very well with the observed data. Results - The results of the full model (structural and measurement models) indicated the following fit indices: χ²=39.492, degree of freedom=25, provability level=0.033, RMR=0.047, GFI=0.948, AGFI=0.906, NNFI=0.958, CFI=0.984, and RMSEA=0.060. The effects of service quality on purchase intention, service quality on innovativeness, and innovativeness on purchase intention we resignificant. We also examined the statistical significance of the mediation effects using the Sobeltest and found further evidence to support service quality and purchase intention through innovation. Conclusions - These results suggest that, if organic food shops want to achieve a greater level of competitiveness, they must try to raise the quality of their service and actively promote the innovativeness of organic food.

In this investigation, the accumulation mineralization and annual cycle of organic P has been studied in grassland ecosysterns of a Z japonica grassland and a M sinensis grassland on Mt. Kwanak. The basic models of the accumulation and mineralization for ash components of a grass-litter have been presented as the equations (1), (2), and (3). The equations (7)~(10) for organic P are derived from these basic concepts. There was a highty significant relationship between organic matter and organic P. The estimates between organic matter and organic P correlated very high significance. The parameter factors k or k' of mineralization of organic P for the Z. japonica and M sinensis asslands were k=0.412 or k'=0.292 and k=0.224 or k'=0.183, respectively. The time required for a cycle to be completed from organic P to inorganic P of 50, 95 and 99 % are 3.9, 16.7 and 27.8 years in the Z. japonica grassland and 4.1, 17.7 and 29.4 years in the M sinensis grassland. The annual P cycle formulae for mineralization were based on the equations (5), (11) and (12). Annual yields of mineralization for organic P in the steady state grasslands of Z. japonica and M sinensis were 0.407 and 0.504g /$m^2$, respectively.

The objective of this study was to assess the variation in the concentration of assimilable organic carbon (AOC) in a drinking water resource, and investigate the characteristics of AOC derived from algae. The seasonal change in AOC at the Kamafusa dam corresponded to changes in the algal cell number. In order to understand the relationship between AOC and algae in a water resource and water purification plant, two kinds of laboratory experiment were performed. The algal culture experiment showed that extracellular organic matter (EOM) that was released during the growth of Phormidium tenue with M-11 medium led to significant increases in the AOC concentration, but no significant variation in the AOC concentration was observed with CT medium containing a high dissolved organic carbon concentration. The chlorination experiment showed that the AOC included in EOM was not easily removed by chlorination, although the AOC included in intercellular organic matter released from the algal cells by chlorination was removed under conditions where residual chlorine was detected.
