Classic rationalist architecture came to play an important role in modern architectural discourse in the 1970s. But it has declined since the death of its most representative architects Aldo Rossi and O. M. Ungers. However, the phenomenon to be noted is that a new momentum was brought to the German architectural scene through some remarkable achievements by the disciples of Ungers after 2000. This study aims to read this phenomenon on the topography of german architecture and to catch out what potential it has to create balance in the international architectural debate. It is not the aim to analyze a single architect in detail, but to compare some important architects like Hans Kollhoff, Max Dudler, Eun-Young Yi and Uwe Schröder. And further the study will try to give an overview of how far this phenomenon can change the topography of the German architectural scene. The buildings that have been examined here are Daimler Chrysler Building, Grimm Zentrum, Stuttgart City Library, and Haus Hundertacht. Through this study, it was found that some architects continue the attitude and the architectural languages of O. M. Ungers and develope their own unique architecture. And this phenomenon has the potential to influence todays architectural debate on a global scale.

YNbO4:Yb3+/Er3+ is synthesized using a solid-state reaction process with a LiCl flux. The effects of the Er/(Yb+Er) ratios (REr) on the up-conversion (UC) and down-conversion (DC) spectra are investigated. The XRD data confirm that the Yb3+ and Er3+ ions are fully substituted for the Y3+ sites. The UC emission spectra activated by 980 nm consists of green and red emission bands, which originate from the Er3+ ions through an energy transfer (ET) process from Yb3+ to Er3+. The UC emission intensity depends on the REr value, and the findings demonstrate that REr ≤ 0.14 is suitable for an effective UC process. The DC emission spectra under 269 nm radiation of the synthesized powders exhibits not only a strong blue emission assigned to the [NbO4]3− niobates, but also green peaks that originate from the Er3+ ions through an ET process between [NbO4]3− and Er3+.

The aim of this study was to investigate kinematic mechanism of gait different road conditions(dry vs. oil) in order women. For this study, twenty older women and ten young women participated in this research. twelve infrared cameras were used to collect data. It appeared that the gait strategies of older women were slower velocity and higher CoM than young women. Depending on road conditions, gait velocities of dominant muscle older women on dry surface were faster than dominant sense older women, but those of them were inverse on oil surface. The slip displacement of dominant muscle older women was less than young women, but the slip displacement of dominant sense older women was greater than young women. In case of blind during stance phase on oil surface, the rotational motion of the ankle and knee joints were increased. In conclusion, older women were subjected to self-organization theory and phase shift in dynamic theory.

This study was performed to measure the concentration of odorous compounds and dilution ratio values at each part of the anaerobic digester process with composting facilities using swine manure and food waste. Complex odors, ammonia, volatile fatty acids and sulfur compounds were measured at each part of the process. Complex odors measured during swine manure storage, food waste storage and in the digested liquid tank, were 35,312 Odor Unit(OU), 39,086 OU and 17,733 OU, respectively. The odor contribution index was calculated by the concentration of odorous compounds during each process divided by the threshold limit. As a result, the major odorous compound that appeared during swine manure storage, food waste storage and in the digested liquid tank was hydrogen sulfide. On the other hand, the major odorous compound in the other processes was ammonia. The overall average concentrations of ammonia were highest in the digested liquid tank(337 ppm) and the separated liquid tank(131 ppm). Wastewater treatment process(10.9 ppm) and deodorization process(11.6 ppm) revealed the lowest concentration of ammonia. The overall average concentration of total volatile fatty acids(TVFAs) was 102.8 ppb during food waste storage and among the TVFAs, the main element was propionic acid(66.1 ppb). Sulfur compounds were only detected during swine manure storage, food waste storage and in the digested liquid tank. The dominant sulfur compound was hydrogen sulfide during swine manure storage(96.3 ppm) and methyl mercaptan during food waste storage(17.7 ppm) and dimethyl sulfide during food waste storage(34.5 ppm).

This study was carried out to provide the stable and homogeneous sample for the proficiency test which was applied for the olfactory dilution method of the offensive odor. For this purpose, the relationship between VOCs concentration and air dilution test results were analysed. As the results, the mixture of 7.1 ppm of toluene and m-xylene were suitable as a low level of PTM(proficiency test material) for air dilution olfactory method. In addition, time stability and homogeneity between samples were investigated through the time of 6 hr ~ 48 hr. As the results, the stability of sample concentration with GC analysis was shown as 5.1% RSD for toluene and 6.8 %RSD for xylene, respectively. The stability of sample was 5.4 %RSD in terms of air dilution olfactory method.

Swine manure discharged from pigery emits various odorous compounds. The most common method to reduce such odors is adding feed additives to swine feeds. However, whether the effects of such methods are truly effective are controversial. This research contrasts the aldehyde compound emission characteristics and removal effects from a treatment group, which were given feeds added with feed additives, to a control group, which were given feeds without feed additives. Sixty swine of age 26~28 days were evenly divided into six sections within an incubator type pigsty - each section contained ten weaners. Five types of feed additives, either currently in the market or in development were supplied. Gases sampled from the headspace in the odor producing reactor were analyzed by GC. Major malodorous compounds were estimated by the concentrations and threshold values from the detected components. Since 95.3% of the odor comes from isobutyraldehyde out of six types of aldehyde compounds (acetaldehyde, propionaldehyde, isobutyraldehyde, n-butyraldehyde, i-valeraldehyde, n-valeraldehyde), it can be regarded as the most critical compound contributing to pigsty odor. Aldehyde compounds showed statistically significant correlation with elimination of sulfide compounds and trimethylamine

Since 2011, proficiency test for the air dilution olfactory method started in Korea for the evaluation of the authorized odor inspection agencies’ analysis skill. For this purpose, sulfur compounds of PTMs (proficiency test materials) were made and investigated for the application to the proficiency test as a complex malodor sample. Time stability and homogeneity between samples were analysed for the PTM which was made with 10 ppm of DMS and 10 ppm of DMDS. As the results, the stability of sample concentration with GC analysis was shown around 6%RSD through the time of 6~48 hr. In addition, dilution number during the same test period appeared almost stable, less than 6%RSD in air dilution olfactory method. The reproducibility results of four laboratories showed very similar results except one lab which was caused by the elder panel characteristics.

Odors were produced in the reactor where contained the swine excreta sampled from the pigery and were analyzed the major odor materials based on the odor contribution index. The container hoggery where six pens were separated was set up in S-myun, Gyeonggi-do, Korea: one was control group, the other were experimental group. Sixty weaners were raised and their excreta were sampled every week to the test of the effect of feed type probiotics. Some probiotics showed very effective deodorizing activity during the whole experimental periods. All products had positive effects on the reducing odor intensities after 4 to 5 week periods. The odor contribution analysis represented the main odor compounds were trimethylamine and volatile sulfur compounds such as hydrogen sulfide, mercaptane, and dimethyl sulfide.

Occurrence of livestock malodor cause to increase in health impact and thus to increase in public interest. Therefore scientific methods to decrease odor is required. Decrease of odor from cow and pig excreata, however, has not fully been successful. The purpose of this research was to select and assess the microorganism can reduce NH₃ produced from cow excreata. Microorganisms which having potential to decrease odor were isolated from cow excreata The strain NIAST-1 which can decrease odor material, was isolated from among the samples of livestock farm located in Yang-phyang. The isolated strain was identified as Pseudomonas stutzeri with respect to its physiological characteristics and 16s RNA sequencing method. Cell-free supernatant was found to have good and stable odor removing activity. Optimal condition and composition of culture medium were determined as follows: glucose (anhydride) 1.2% (w/v), yeast extract 0.6% (v/v), and temperature (28 ℃), agitaion rate (180 rpm) and aeration rate(0.1 L/min). In field test, microbial agents composed of ASA(Pseudomonas stutzerie) showed marked removal activity of ammonia gas (25%) and hydrogen sulfide (14.5%) gas produced from five ton scale pig storage container. Also this study focussed to assay the characteristics and utilization of environment friendly agricultural materials at laboratory and greenhouse.

Odor intensities, odor concentrations and volatile amine compounds were investigated at the two piggeries in Korea and the one in Japan. It was confirmed that the piggery where odor control had been carried out intentionally showed the lower values of sensory measurement than those where the odor control had not been under consideration and also found that the concentrations of volatile amines in the odor-controlled piggery showed lower values rather than the uncontrolled. In this investigation, we conclude that the activities such as circulation of air in pig houses, spraying deodorants and feeding the additive that is effective for reducing malodors from piggery could decrease the odors and the concentrations of volatile amines that are the cause of offensive odors from piggery.

The purpose of this study was to investigate the food preference and attitude according to six emotions in female university students. Also, it was studied whether the desire to food consumption was changed by each mood. The selfreported questionnaire was used to 285 female university students. There were the significant differences in food preference according to emotions. Pizza & pasta, ice cream and cake were preferred during happiness and amusement. In sadness and anger, alcohol was the most preferred food item. There was the preference of beverage, Jjigae & Baikban, ice cream and snack during relaxation. Chocolate showed the highest preference during depression. The taste and flavor was the main preference attributes during all emotions. The self-assessed food intake during happiness, amusement, anger and relaxation was increased but it was decreased during sadness and depression (p<0.001).

"Sick car syndrome" is known as a syndrome having latent health damage caused by complex smell of the assorted chemicals such as PVC and ABS which was components of new car interior trim (sheet, dashboard, audio case, cable, safety glass, synthetic rubber, and adhesive). The impact of interior trim on VOC levels was evaluated by testing with leather or fabric trims. Concentrations of VOCs and formaldehyde (HCHO) discharged from the car interior trims (2 sheet covers and 1 headliner) fixed in the sample holder of the small chamber were analyzed quantitatively and qualitatively. Concentrations of TVOC and HCHO emitted from 3 samples increased with increasing temperature and time. Concentration of TVOC emitted from PVC foam leather was highest under experimental conditions.

The dried persimmon was effective in caring an inflammation, an ulcer and a burn and preventing hypertension and arteriosclerosis. At the Jejungsinpyun. dried persimmons gruel was beneficial to stomach and intestine and toned down voice. Based on Jejungsinpyuns and Sikryochanyo, dried persimmons gruel was developed for modern people. To standardize the dried persimmons gruel, physical properties and consumer acceptability was examined. The procedures of dried persimmons gruel was to make dried persimmons juice after soaking dried persimmons with same volume water during 24 hr and blending. To decrease the astringent taste of dried persimmons, dried persimmons juice and water with cinnamon (2%) was mixed and simmered during 3 min. Dried persimmons paste with cinnamon was added and the gruel was boiled more during 5 min. dried persimmons gruel was completed. The dried persimmons gruel were divided of 5 groups consisted of each 10, 15, 20, 25, 30 g dried persimmons. As dried persimmons content increased, lightness, apparent viscosity decreased. Acceptability test indicated the sample of dried persimmons : rice ratio at 2 : 5 had the highest overall acceptability and flavor. Considered to each, the sample of the dried persimmons : rice ratio at 2 : 5 met the purpose of the study.

The characteristics of odor and VOCs emitted from a sewage treatment plant was investigated to provide the basic informations in the design of odor and VOCs treatment processes. The sewage treatment plant which treated domestic wastewater only and consisted of a flow equalization tank, thicker, and sludge container was selected. Odor and VOCs sampled three times (June - July) at the temperatures ranging from 24℃ to 27℃ were analyzed by GC/MS and GC/FPD. Odors were hydrogen sulfide, dimethylsulfide, ammonia, and styrene. Among them, the main compounds were dimethyldisulfide (14.45~2,340.91 O.U.) and ammonia (18.51~16,520 O.U.). The order of odor dilution ratio and odor unit can be listed as follows : Sludge container ＞ Flow equalization tank ＞ Thicker. The main VOC produced from sewage treatment plant was benzenes, and the others were dichloromethane, toluene, ethylbenzene, m,p-xylene, styrene, 1,2,4,-trimethylbenzene, 1,3-dichlorobenzene, and 1,2-dichlorobenzene. The concentration of toluene of a flow equalization tank, thicker, and sludge container were produced from 70.38 ppb to 103.07 ppb, from 28.18 ppb to 40.35 ppb, and from 67.92 ppb to 180.26 ppb. The producing order of VOC can be listed as follows : Sludge container ＞ Flow equalization tank ＞ Thicker.
