The study aims to develop a teaching-learning plan that can solve the problem of the clothing and textiles area faced by the teenager as course of critical science perspective improving the empowerment. As a research method, it was conceptualized by applying the Laster(1986)'s curriculum development process. And it was applied to the conceptual framework of practical reasoning presented in: "Family, Food and Society A Teacher's guide" (Staaland & Storm, 1996). The results of this study are summarized as follows. First, based on the results of reviewing literature related to the clothing and textiles area, ongoing concerns related to the clothing and textiles is "Should we do with regard to clothing and textiles for families in the community? The valued ends is defined as a complex position with a high degree of freedom and a high responsibility, and the goal of learning is interdependence, emotional maturity, intellectual development, and communication ability. For the contents of education and activity structure, practical reasoning process was used as conceptual framework of education contents, and included sub-concerns, broad concepts, sub-concepts and intellectual and social skills. Second, based on the practical reasoning, we developed a teaching and learning plan in the clothing and textiles. As a result, a total of 12 plan of 5 modules were developed. And were developed a total of 31 tutorials, reading materials, picture materials, group activities, and video materials. The results of this study can be applied to teachers who want to try out practical inference process in class or teachers who have difficulty in practicing reasoning process in the field.

Whether to reduce the current 'screen quota' for domestic films in conjunction with the FTA discussions between Korea and the United States is one of the hotly debated issues in Korea. Using Toulmin's Argumentation Model, this study attempts to trace the use of data and warrants for each pro and con claims as portrayed in newspaper editorial columns and to find its rhetorical significance. A total of 67 editorial columns were collected from 9 nationwide news dailies in Korea for the purpose. The rhetorical analysis of those articles showed that the major warrants used in each pro and con opinion were absent of the potential issues of the opponents, which inherently fails to invite rebuttals from the opposite sides. This conceptual wall in each argumentation models implies an inactive conversation and subsequent absence of clash between the pro and con argumentation fields. It is thus suggested for opinion writers to find more adequate evidences to support the data and warrants to hold persuasive power of their respective claims, ultimately to enhance the public discourse among citizens.

This experiment was conducted to investigate the effect of feeding monensin on the growth performance and ruminal fermentation characteristics of Han-Woo cattle. Seventy two uncastrated Han-Woo male cattle(BW 267 kg) were randomly allotted to 0, 22, and 33 ppm monensin treatments, three replicates per treatment and eight heads per replicate. Animals were kept in an open barn for an 140-d feeding trial, Concentrates containing different levels of monensin and rice straw cut in 15cm length were fed ad libitum separately. The results obtained from this study were summarized as follows. 1. No significant difference was found in daily gain by monensin feeding. 2. Monensin did not affect the total feed (concentrate + roughage) intake: however, as the monensin level increased, the total feed intake tended to decrease, resulting in 5 % reduction in 33 ppm monensin treatment. 3. Although no significant difference was found among three treatments, 22 and 33 ppm monensin improved the feed efficiency(total feed/gain) by 5.2 % and 5.1 %, respectively, as compared to the 0 ppm monensin treatment. 4. Monensin did not affect the concentrations of ruminal total VFA and acetic acid consistently. Although not significant, monensin feeding of 22 and 33 ppm caused marked increase in ruminal propionic acid concentration, 13.8 % and 19.3 %, respectively. Ruminal butyric acid concentration decreased as monensin level increased. Monensin feeding, regardless of level, decreased the A/P ratio by 12.5 %. In conclusiuon, monensin feeding increased the propionic acid concentration, and decreased the butyric acid concentration and A/P ratio in the rumen. Animals fed monensin consumed less feed, causing the improvement in feed efficiency. Thus, monensin appeared to be a useful feed additive, directing the rumen fermentation in a more productive way. Feed efficiency improved similarly both in 22 and 33 ppm monensin treatments, indicating that 22 ppm might be good enough rather than the 33 ppm monensin level.

This study aimed to the adsorption-removal of high- radioactive iodide (I) contained in the initially generated high-radioactive seawater waste (HSW), with the use of AgX (Ag-impregnated X zeolite). Adsorption of I by AgX (hereafter denoted as AgX-I adsorption) was increased by increasing the Ag-impregnated concentration in AgX, and its concentration was suitable at about 30 wt%. Because of AgCl precipitation by chloride ions contained in seawater waste, the leaching yields of Ag from AgX (Ag-impregnated concentration : about 30~35 wt%) was less than those in distilled water (< 1 mg/L). AgX-I adsorption was above 99% in the initial iodide concentration ($C_i$) of 0.01~10 mg/L at m/V (ratio of weight of adsorbent to solution volume)=2.5 g/L. This shows that efficient removal of I is possible. AgX-I adsorption was found to be more effective in distilled water than in seawater waste, and the influence of solution temperature was insignificant. Ag-I adsorption was better described by a Freundlich isotherm rather than a Langmuir isotherm. AgX-I adsorption kinetics can be expressed by a pseudo-second order rate equation. The adsorption rate constants ($k_2$) decreased by increasing $C_i$, and conversely increased by increasing the ratio of m/V and the solution temperature. This time, the activation energy of AgX-I adsorption was about 6.3 kJ/mol. This suggests that AgX-I adsorption is dominated by physical adsorption with weaker bonds. The evaluation of thermodynamic parameters (a negative Gibbs free energy and a positive Enthalpy) indicates that AgX-I adsorption is a spontaneous reaction (forward reaction), and an endothermic reaction indicating that higher temperatures are favored.

The purpose of this study was to analyze commemoration characteristics of fifty-nine Vietnam war memorials in Korea(VWMK) including monuments and national cemeteries from landscape architectural point of view such as location, spacial characteristic, landscape detail, sculpture, and interpretive text. Based on the commemoration characteristics of the analysis, the commemoration culture among Vietnam, the U.S.A., and Korea were studied and differences compared. The results are as follows. First, monuments were mainly located in public open space such as national cemeteries, parks, and plaza, and some of them were elected along with Korea war memorials to honor Vietnam war veterans at the national level. Second, because the monuments were relatively small and memorial towers were conventionally built on a square platform, the memorial style had been simply standardized to stereotype the commemoration characteristics. Third, outmoded memorial towers, stone plates, emblems, and memorial walls were used as main landscape details and standardized facilities were considered from an artistic and social point of view. Fourth, realistic soldier statues to show heroic and humanitarian image were in majority, while symbolic and abstract sculpture were small in number, they were mostly conventional and unexpressive. Fifth, the causes of participation in the Vietnam War were predominantly expressed as 'defending freedom', 'keeping world peace', and 'national economic development' based on anti-communism and patriotism, and also the collectivity of Vietnam War veterans by troop and local level was emphasized through engraving each veterans's name on towers, plates, and walls. VWMK are mostly conventional and stereotyped in style and show strongly national official memory and the collectivity of veterans from a sociopolitical perspective, and aim for anti-communistic patriotism ideologically. Further study and projects will be required to make creative and innovative memorials and to study how to rethink sublime fundamental themes like war, death, and the individual veteran's experience in VWMK.

The accidental releases of total petroleum hydrocarbons (TPH) due to oil spills frequently ended up with soil and ground water pollution. TPH may be degraded through physicochemical and biological processes in the environment but with relatively slow rates. In this study an attempt has been made to develop an integrated chemical and biological treatment technology in order to establish an efficient and environment-friendly restoration technology for the TPH contaminated soils. A Fenton-like reaction was employed as a preceding chemical treatment process and a bioaugmentation process utilizing a diesel fuel degrader consortium was subsequently applied as a biological treatment process. An efficient chemical removal of TPH from soils occurred when the surfactant OP-10S (0.05%) and oxidants ($FeSO_4$ 4%, and $H_2O_2$ 5%) were used. Bioaugmentation of the degrader consortium into the soil slurry led to an increase in their population density at least two orders of magnitude, indicating a good survival of the degradative populations in the contaminated soils ($10^8-10^9$ CFU/g slurry). TPH removal efficiencies for the Fenton-treated soils increased by at least 57% when the soils were subjected to bioaugmentation of the degradative consortium. However, relatively lower TPH treatment efficiencies (79-83%) have been observed in the soils treated with Fenton and the degraders as opposed to the control (95%) that was left with no treatment. This appeared to be due to the presence of free radicals and other oxidative products generated during the Fenton treatment which might inhibit their degradation activity. The findings in this study will contribute to development of efficient bioremediation treatment technologies for TPH-contaminated soils and sediments in the environment.

The bamboo is a plant whose culm grows straight up. This growing characteristics has been widely utilized in industry and craft. But the developments of handcraft making and horticultural techniques in recent years become to demand the bent bamboo culms. This study has been conducted at the experimental grove located at Hyunnae Ri, Okkye Myun, Myungju Gun, Kangwon Do since 1960. Although it has been known that the secret for which bamboo shoots complet growth within 40 odd days lies in their rhizomes, this writer felt the bamboo culm sheath might be another factor in addition. Hence some were stripped of sheath in this bending study as the following: 1. Time of sheath stripping. 2. Direction of sheath stripped for arbitrary bending. 3. Accuracy of bending following the size (growth) of bamboo shoots. The following results were obtained: 1. Bamboo shoots begin to appear in April. But the bamboo shot up in June showed the best bending result with 68% of bending efficiency. 2. Bending of the culm was facilitated by stripping off the sheath located on the side of the direction toward which bending was desired. By doing this, the culm could be bent as much as 90 degrees. But the culm totally stripped of sheath could be bent in any direction. 3. In order to determine the accuracy of bending of bamboo shoots growing, sheath were stripped off the shoots of which height ranged from 10 centimeter to 150 centimeters. The shoots with height of 110 centimeters showed the best result with 90%.

This study was conducted to determine biological characteristics of Acorus calamus L. angustatus by using aqueous, ethanol and methanol extracts from the leaves and the rhizomes of Acorus calamus L. angustatus plants. The highest total phenol contents were found in the extracts from the leaves of Acorus calamus L. angustatus ($68.4mg{\cdot}L^{-1}$) followed by rhizome ($49.3mg{\cdot}L^{-1}$). At $1,000mg{\cdot}L^{-1}$ the free radical scavenging activity of 1, 1-Diphenyl-2-picrylhydrazyl showed the highest activity in the extracts of the leaves and the rhizomes by 86.3% and 86.1%, respectively. Total flavonoid contents at $2,000mg{\cdot}L^{-1}$ extracts showed the greatest amount in the aqueous leaf extracts ($61.1mg{\cdot}L^{-1}$), and the ethanol rhizome extracts ($15.4mg{\cdot}L^{-1}$). Nitrite radical scavenging activity at $2,000mg{\cdot}L^{-1}$ was highest in the methanol extracts from leaves and rhizomes by 75.7% and 77.9%, respectively. Mushroom tyrosinase inhibition activity of leaves and rhizome from the Acorus calamus L. angustatus was very low, showing less than 1.3% regardless of the extract solvent, plant part, and concentration. These results indicated that methanol extracts from leaves exhibited higher biological activities than other extracts from rhizomes.

Die Einzelwissenschaften, zum Beispiel, die Biologie, die Psychologie, Soziologie behandeln heuzutage den Menschen. Aber sie alle behandeln den Menschen nach ihren eigenen Gesichtpunkten. Infolgedessen $k{\ddot{o}}nnen$ die Einzelwissenschaften den ganzen Menschen als den Menschen nicht $ber{\ddot{u}}ksichtigen$. Jhre Anthropologien $m{\ddot{u}}{\ss}en$ daher weitgehend $beschr{\ddot{a}}nkt$ bleiben. Dagegen entwickelte Max Scheler im letzten Jahrhundert eine neue philosophische Anthropologie. Seine Anthropologie ist wirklich neu und grundgehend. Diese Anthropologie bestimmt den Menschen als Geist, Freiheit, Person. Aber Max Scheler betont allzusehr "den Geist" in seiner philosophischen Anthropologie und infolgedessen distanzierter sich vom "Leben" in seinem $Menschenverst{\ddot{a}}ndnis$. Die Verfasserin sieht hier in dieser philosophischen Anthropologie einen Dualismus zwischen den Geist und das leben. Und Verfasserin findet eine Integration von Geist und Leben in der ontologischen Anthropologie bei Edith Stein. Diese ontologische Anthropologie charakterisiert sich $folgenderma{\ss}en$. 1. Es ist eine Anthropologie des "$Ge{\ddot{o}}ffnet$-Seins." 2. Es ist eine Anthropologie des "$Gef{\ddot{u}}hlt$-Seins." 3. Es ist eine Anthropologie des "Einheits-Seins." Die Verfasserin behauptet infolgedessen die ontologische Anthropologie bei Edith Stein sei eine geeignete und $sachm{\ddot{a}}{\ss}ige$ Anthropologie.

There is a growing voice that medical information should be shared because it can prepare for genetic diseases or cancer by analyzing and utilizing medical information in big data or artificial intelligence to develop medical technology and improve patient care. The utilization and protection of patients' personal information are the same as two sides of the same coin. Medical institutions or medical personnel should take extra caution in handling personal information with high environmental distinct characteristics and sensitivity, which is different from general information processors. In general, the patient's personal information is processed by medical personnel or medical institutions through the processes of collection, creation, and destruction. Still, the use of terms related to personal information in the Medical Service Act is jumbled, or the scope of application is unclear, so it relies on the interpretation of precedents. For the medical personnel or the founder of the medical institution, in the case of infringement of Article 24(4), it cannot be regarded that it means only medical treatment information among personal information, whether or not it should be treated the same as the personal information under Article 23, because the sensitive information of patients is recorded, saved, and stored in electronic medical records. Although the prohibition of information leakage under Article 19 of the Medical Service Act has a revision; 'secret' that was learned in business was revised to 'information', but only the name was changed, and the benefit and protection of the law is the same as the 'secret' of the criminal law, such that the patient's right to self-determination of personal information is not protected. The Privacy Law and the Local Health Act consider the benefit and protection of the law in 'information learned in business' as the right to self-determination of personal information and stipulate the same penalties for personal information infringement such as leakage, forgery, alteration, and damage. The privacy regulations of the Medical Service Act require that the terms be adjusted uniformly because the jumbled use of terms can confuse information subjects, information processors, and shows certain limitations on the protection of personal information because the contents or scope of the regulations of the Medical Service Law for special corporations and the Privacy Law may cause confusion in interpretation. The patient's personal information is sensitive and must be safely protected in its use and processing. Personal information must be processed in accordance with the protection principle of Privacy Law, and the rights such as privacy, freedom, personal rights, and the right to self-determination of personal information of patients or guardians, the information subject, must be guaranteed.
