This paper presents the feature profile evolution silicon deep trench etching, which is very crucial for the commercial wafer process application. The silicon deep trenches were etched with the SF6 gas & Hbr gas based process recipe. The optimized silicon deep trench process resulted in vertical profiles (87o~90o) with loading effect of < 1%. The process recipes were developed for the silicon deep trench etching applications. This scheme provides vertically profiles without notching of top corner was observed. In this study, the production of SF6 gas based silicon deep trench etch process much more strongly than expected on the basis of Hbr gas trench process that have been investigated by scanning electron microscope (SEM). Based on the test results, it is concluded that the silicon deep trench etching shows the sufficient profile for practical MOS FET silicon deep trench technology process.

In order to investigate a practical application of fibrous adsorbents to heavy metal ions, amidoxime fibers, as a particular class of solid chelate agents, were prepared by hydroxylamine treatment for acrylic fibers in a recipe of neutralization. Among the important problems from plant effluents are toxic concentrations of heavy metals such as copper. Accordingly, the properties of Cu (II) adsorption and its chelates were studied. The results obtained are as follows; The fibrous adsorbents have the property of increasing the swelling volumes by amidoximation. The adsorption of Cu (II) ion is characterized by an endothermic reaction, which is estimated as the plus values in the enthalpy change ($\delta$H=1.30 Kcal/mol. and 3.14 Kcal/mol.). The Cu (II) ions are adsorbed in the range of pH $3\~8$ and the maximum adsorptions are occurred about pH 8. Owing to the anions $(NO_3^-,\;Cl^-)$ of copper salts, amidoxime fibers form 1:1 and 2:1 (ligand: metal) chelating complexes with Cu (II). The nitrate anion chelates to amide I (NH) of amidoxime groups and the chlorine anion does to nitrosyl (NO). These effects relate to the crystallization of the complex and the thermal property.

In this paper, we checked health problems of patients who suffered from arthritis. After assessing each patients condition, in order to alleviate their sufferings, we introduced several methods of aromatherapy as a holistic approach to these health problems. Aromatherapy is used of essential oils, which are obtained from aromatic plants, can be defined as a nature-friendly complementary/alternative method, has its great merit in its each way of application. If the arthritis condition is localized, massage,compress or poultices, and hand or foot baths are most effective. Many of essential oils in the recipe have dual benefits, as anti-inflammative and analgesic agents. The Juniper and carrot seed aid in eliminating fluid and toxin accumulation in the joint and surrounding tissue. There are many different courses available and health professional should choose one that is relevant to clinical practice. Considering the future of nursing as a major contribution in the consumer-centered structure of medical health service, aromatherapy as a complementary/alternative method is expected to contribute not only to establishing more effective health service but also to resolving chronic health problems of arthritis.

As social interest in acne treatment has grown, various external preparations have been developed and studied. So, we investigated the external prescription which can treat acne in medical classics, then reviewed and divided it by dynasty. The data for analysis of Herbal formula was taken from 'medicine Dictionary of traditional Chinese medicine prescriptions(中醫方劑大辭典)'. 31 external medicines were searched, 3 were before song(宋) dynasty, 11 were Song(宋) dynasty, 11 were Yuan(元) dynasty, 7 were Ming(明) dynasty and 7 were Qing(淸) dynasty. The recipe and usage were only making them pill(丸) and paste(膏) using grinded medicinal herbs, then rubbing to face. As the age developed, unique manufacturing process(i.e fermentation method), and usage(i.e time-based usage, herbal medicine extracts for wash) were proposed. The external application with oriental medicine for acne used with Angelicae Gahuricae Radix(n=12), Bletillae Rhizoma(n=8), Syzygii Flos, Saposhnikoviae Radix(n=7) and so on. In particular, Bletillae Rhizoma was searched with high frequency in this study, but it was not included or studied in patent composition. The results of this study will provide basic data for future experiments and clinical studies.

This survey was conducted to investigate the present conditions of operational management in the 45 animal manure public resource center (APRC) in Korea. The regional distribution, processing capacity per year, capacity of liquid fertilizer storage tank, solid-liquid separation, utilization of facilities, odor reduction facility, on-site odor strength, complained in the community, liquid fertilizer sprayed area, use the Agrix, land application recipe, composting degree, quality management and general grading were surveyed and evaluated. General grading was divided with 5 stages (very good, good, fair, lack and bad). The number of evaluated "very good" animal manure public resource center was 7, and "good" was 5 and more than "fair" was 27. However, the number of evaluated negatively including "lack" and "bad" was occupied as 40% of the 45 animal manure public resource center.

Low sodium (1,300 mg) containing menu items and recipes applicable to institutional food services were developed while maintaining taste and nutrition contents. These developed recipes were used in a total of 258 dish items, including 39 one-dish meals, 43 guk or jjigae (soups or pot stews), 59 meat or fish side-dishes, 94 vegetable side-dishes, 9 jeons (pan-fried dishes), and 14 kimchis or pickles. A total of 90 menu items using 258 dishes were categorized into one-dish menu items or Korean dining table-setting items. They were re-sorted to soup or pot stew containing or not containing items. The protein content was significantly higher in one-dish menus than in Korean dining table-setting menus (p<0.05), whereas the energy, carbohydrates, lipids, and sodium did not differ significantly between them. Menus including guk showed no significant differences in energy, carbohydrates, lipids, or sodium when compared with menus not including guk. For practical application of these developed low sodium menu items for institutional food services, education manuals for nutrition should be developed, and networks among governmental agencies, institutional food services and research institutions should be established.

Microstructure and electrical properties of Ga-doped ZnO (GZO) films grown on $Al_2O_3$ templates by Pulsed Laser Deposition (PLD) are investigated utilizing X-ray diffraction method and Hall measurement, respectively. In order to determine the optimized operating condition of the PLD, statistical design of experiment (DOE) is employed. It provides the systematic and efficient methodology for characterization and modeling of PLD processing with a relatively small number of experiments. The most optimized recipe of the process factors is obtained by response optimizer in Minitab.

In order to examine the pre-industrial application product quality characteristics of yanggang (a type of traditional Korean confectionery) with varying levels of Palatinose, this study conducted multiple preliminary experiments. By applying different amounts of Palatinose (1%, 2%, 3%, 4%) and adhering to a recipe suitable for commercial products, the yanggang was produced under controlled manufacturing conditions. While the moisture content of the manufactured yanggang adhered to the established manufacturing standard, showing minimal variations, there were statistically significant differences observed with an increase in the Palatinose proportion, exhibiting a trend akin to findings from other yanggang studies. Similarly, there were slight but statistically significant differences observed in soluble solids content and pH, though these differences were not found to have a significant impact. The addition of Palatinose did not induce changes in the elasticity (springiness) and firmness (gumminess) of the yanggang, nor in its chewiness, as the Palatinose content increased. Despite a reduction in calorie content, the addition of Palatinose did not influence the appearance and taste of the yanggang.
