Sex steroid hormones are key molecules to prepare the decidual response and their levels are important in this process. Imbalances of the levels of steroid hormones are cause of implantation failure and other diseases including physical weakness. Androgen replacement therapy or selective androgen receptor modulator are used to overcome various diseases but long-term use may cause of side effects. In previous report, it is suggested that the steroid hormonal complexes derived from pig enhance the proliferation of satellite cell. Therefore, to evaluate the possible usage of steroid hormonal complex derived from pig testis (tS-C), the effects of tS-C on uterine response were studied using the model of artificial decidua. tS-C did not disturb the rhythmical estrus cycle. Artificial-induced decidual response was normally induced in tS-C administered mice. The histological characters of the decidua of tS-C administered mice were not different from the vehicle. The expression patterns of molecular markers of decidua were not different between vehicle and tS-C group. Collectively these results suggested that tS-C does not disturb the uterine responsibility to the embryo. In addition, our results suggested that tS-C can be applied to overcome the various problems such as loss of muscle mass and anemia.

The southwestern continental shelf of the East Sea, Korea developed mud deposits as a belt in the inner shelf area from Pusan to Pohang. The general surface sediments consist of very poorly to poorly sorted muddy sediment. The differences of physical, geological and geomorphic conditions in the study area may control and produce distinctive foraminiferal populations. To establish a baseline of environment for the muddy sediments in the southwestern continental shelf of the East Sea, 17 stations were sampled and proved to contain 45 species of living benthic foraminifera. Analysis of the foraminiferal populations in cluster analysis recognized to five habitat zones. These habitat zones contain distinctive cooccurrences of the entire occurring species. Foraminiferal community composition appeared to be closely interrelated of water masses, depths, nutrients and sediment characters.

In order to improve the hydrophilic property on the surface of d-PMMA(deuterated poly-(methyl methacrylate)) film, it was exposed to oxygen plasma, All experimental conditions were same except to plasma exposure time that was varied from 0 to 180 s, The effects according to the exposure time were identified using contact angles, X-ray reflectometer(XRR), neutron reflectometer(NR), and X-ray photoelectron spectroscopy(XPS). By confirming that as the exposure time increases, water contact angle decreases while the composition of oxygen increases, it was confirmed that the composition of oxygen has a huge influence on improving the hydrophilic property. The physical characters as a function of the exposure time were investigated by the XRR. By analyzing complementally the results of the XRR, NR, and XPS, more detailed chemical bonding conditions were studied by obtaining not only composition of the carbon and oxygen but that of the hydrogen.

The purpose of this study is to investigate the effects of soil amendments for reducing soil compaction at heavy traffic area in golf course. Major results of this research are summarized at follows: 1. In the Lab. experiment, the porosity was improved significantly when the materials, such as peatmoss, charcoal, and tire chip mixtures were used respectively. Especially mixture of sand and 20% peatmoss showed higher effectiveness (10%) in porosity, comparing with ordinary sand. This soil mixture(sand 80%+peatmoss 20%) was observed the best in water retention, soil hardness and hydrauric conductivity. 2. In the greenhouse experiment, traffic pressure was given 7 times a day on several combination of mixture treatments to see the top dry weight. The soil mixture of 20% peatmoss showed the highest in the top dry weight. When the more traffic pressure(15 time/day) were given on the different treatment, the top dry weight was significantly reduced. However, the mixture of 20% peatmoss also had the least influence on this type of heavy traffic. 3. In the field experiment, the soil amendments were treated in traffic area f golf course, and observed at 30days, 60days, 90days, 120days after treatment. Visual turf quality(color), root length and soil compaction were compared to those of control. As a result, overall treatments with soil amendments were effective, which showed better turf quality and less soil compaction. 4. In the field test, physical characters of soil (such as soil hardness and hydrauric conductivity) in sand+tire chip+peatmoss(60:20:20, %, v/v) treatment was significantly improved. Also in the slow increasing of traffic, the soil compaction was the most effective in reducing soil hardness.

A lot of city have different characteristics in their location, space and environment each other. These characters are the factors showing inherent placeness of each space, and those factors should be reflected sufficiently in urban planning and development. Nonetheless, there are many parts that are not actually reflected in the plan, and this creates a space of unexpected arming. Especially, port area in a port city has strong characteristics of culture, history, geography and environment of the city concerned so it must make more creative and unique space. Therefore, it is considered that not only the physical factors but also the social factors should be actively reflected to highlight the place character of the port space. In this paper we are to construct the factors forming the placeness of port space based on the Form Based Codes rising as a flexible urban planning method in order to avoid rigidity of existing use district zoning system, and establish the placeness character of each port area.
