  • In the EFL context, Korean students don't have enough opportunities to directly experience the target culture, prompting the need to offer some well-organized culture education in class. The goals of this study are to analyze how many cultural contents are reflected in High School English textbooks and to suggest an implication for cultural learning. These textbooks were carefully examined, focusing on the cultural contents, by four categories: 'cultural skill section', 'cultural patterns', 'related language skills', and 'target countries'. The results of the analysis were like the following: First, although many of the textbooks are dealing with the culture skill sections, their contents were still wanting consistency and were small in quantity. Second, as for the cultural patterns, the pages dealing with behavioral culture were 43%, spiritual culture, 35.7%, material culture, 21.3%. Third, as for the related language skills, the cultural contents in the textbooks were organized in the order of listening, reading, speaking, writing, and cultural skill sections. Since it is impossible to separate language skills from culture, we suggest that the aspects of target culture should be incorporated in various forms into the learning situations. Fourth, as for the issue of target countries, the contents about the general or whole English culture were insufficient. So we suggest that English textbooks should play an essential role in providing students with various cultural information about various English speaking countries.

  • Objectives : It is well known that vegetables and fruits contain minerals, including potassium, sodium and phosphorus etc. Though most oriental herbal medications are made of natural plants, western scientists suppose that they also contain certain amounts of minerals and so are injurious to kidney disease such as chronic renal disease. However, by the reason of the limitation of western medical treatment on kidney disease, many patients depend on oriental medical treatment, which includes taking oriental herbal medicine. So, in order to find out the mineral contents in oriental herbal medicine, and to establish the oriental herbal medication's safety in kidney disease, studies were performed. Methods : In this study, we analyzed 42 oriental herbs commonly used in kidney disease by the Inductively Coupled Plasma(ICP) method. Results : 1. The potassium and sodium contents of oriental herbs were 3-10 times as much as of food. 2. The mineral contents of a daily dose of oriental herbal medicine satisfied the restriction of dietary mineral in CRF, though the amount of mineral intakes by food was considered. Conclusions : The mineral contents of oriental herbal medicine are less than the limits of mineral restriction in renal failure. The yielded results, we carefully suggest that oriental herbal medicine does not induce accumulation of minerals or damage in kidney disease patients.

  • This study was done to analyze the contents of food and nutrition information sites on the internet. In analysis, 276 web sites were used. Web sites from 3 internet search engines(Yahoo, Empas, Naver) were selected on the date of July 15th, 2004. The trained panels evaluated web sites' contents by the assessment tools using 3-point scale(2:strongly agree, 1:agree, 0:disagree). The contents classified by topics were functional foods(46.4%), cuisine and cooking(38.4%), food sanitation and safety(30.4%) and so on. Operators of web sites were individual(35.9%), company(30.4%) and public institution(33.7%). About 89.5% of web sites were operated for unspecified people. Contents of the web sites were well established especially in consistency in title and contents(1.6), scientific basis of explanations(1.2) and benefit of information(1.2) and so on while not well established in providing relevant sites(0.7), providing contact address and feed back mechanism(0.7) and so on. Web sites operated by public institutions are rated significantly higher than web sites operated by individual or company. In conclusion, in order to qualitatively improve food and nutrition information on the internet, continuing monitoring and evaluation are highly required and web sites operated by public institutions shall be developed further.

  • In the smart education era, it is crucial for the teacher to make lecture materials in the form of 3D convergence contents for themselves. In this study, we developed an interactive authoring tool to create 3D convergence contents for the teacher. The proposed system was implemented based on a commercial 3D engine for practicality. To evaluate the usability of the tool, we conducted a satisfaction survey of a focus group. As a result, we concluded that the proposed authoring tool was useful to create desired contents but rather complicated to use due to the text-based script editor. In the following research we will improve the editor so that it can be used in a more intuitive manner.

  • Mulberry plants (Morus alba L.) were grown in pots with the following different nitrogen sources: ammonium sulphate, urea, ammonium nitrate, sodium nitrate + ammonium nitrate ($NO_3:NH_4$=2:1), and sodium nitrate. The effects of the nitrogen sources on mulberry yields, nitrogen recovery, distribution of ions and cation-anion balance (C-A) along leaf sequence and growth stage were investigated. The results were as follows: 1. Leaf yields and nitrogen recovery decreased with increasing $NO_3$-N application rates. 2. Relative cation contents in leaves in the early growth stages showed the following pattern : Na < Mg < Ca < K. However, the order of Ca and K reversed in the later stages. The order of anion contents chifted from $SO_4$ < $NO_3$ < Cl < $H_2PO_4$ in the early stages to $NO_3$ < Cl < $SO_4$ < $H_2PO_4$ in the later stages. 3. Contents of K, $H_2PO_4$, $SO_4$, $NO_3$, T-N and the sum of anion contents (${\sum}A$) were higher in upper leaves whereas Ca, Mg, Cl, the sum of cation contents (${\sum}C$) and (C-A) were higher in lower leaves. 4. When $NO_3$ in leaves decreased, Cl and K as counter-cations increased and consequently Ca decreased. 5. The (C-A) in leaves varied with leaf sequence and growth stage from 700 to 900 me/kg D.M.

  • In producing anamorphic 3D advertisement projects, it is necessary to apply the principles of illusion art to distort the images output to the screen (Image Distortion) so that their display aligns with our visual perception in a real three-dimensional environment. We focuse on the methods of image distortion in the creation of content for anamorphic 3D advertisement screens in this thesis. We propose using Unity 3D's real-time rendering instead of the offline rendering method of compositing method, and employing UV grid mapping to replace the manual correction in Adobe After Effects(AE). The significance of this paper lies in simplifying the image distortion processing workflow in anamorphic 3D projects and optimizing the image distortion creation methods used in compositing method. In outdoor anamorphic 3D advertisement projects, the proposed image distortion creation method demonstrates significant advantages in terms of production time, process simplification, flexibility, and expansion possibilities. Our research provides new perspectives and methods for the creation of anamorphic 3D content, offering theoretical and methodological references for professionals working on similar contents.

  • We investigated the residual contents of sulfur dioxide ($SO_2$) on the 280 kinds of herbal medicines distributed at 8 cities including in Seoul, Busan, Daegu, Gwangju, Jecheon, Yeongju, Geumsan and Jeonju in Korea. The residual contents of $SO_2$ were determinated by modified Monier-Williams method. The residual contents of $SO_2$ were not detected at 206 products in total 280 products. However, it was detected below 100 ppm in 39 products, between 101 and 1000 ppm in 30 products and exceeded 1000 ppm in 5 products. $SO_2$ contents ranged 11 ${\sim}$ 2339 mg/kg (mean 293 mg/kg) at domestic samples distributed. Regardless of region, $SO_2$ contents were not found at Notopterygii Rhizoma, Ligustici Scinensis Rhizoma et Radix, Bombyx Batryticatus, Coicis Semen, Cnidii Rhizoma, Anemarrhenae Rhizoma, Gardeniae Fructus, Alismatis Rhizoma. But it's found at Batatatis Rhizoma, Paeoniae Radix and Codonopsitis Radix of every region collected the samples. $SO_2$ contents were not detected at 58 products which collected cultural fields of dometic. After treated with water wash and hot water extraction, the reduction rates of sulfur dioxide were appeared with 14.3% ${\sim}$ 40.4% and 55.2% ${\sim}$ 100.0%, respectively. These data will be used to establish a criteron of residual sulfur dioxide in herbal medicines.

  • In order to examine the effect of SO$_2$, which is the major component of acid rain, on the peroxidase activity, rice (Oryza sativa) seedlings were grown on the media containing various concentrations of Na$_2$SO$_3$. Na$_2$SO$_3$ concentrations needed for the 50% inhibition of rice seed germination were determined to be 300$\mu\textrm{g}$/ml at pH 7, 8$\mu\textrm{g}$/ml at pH 5 and 2$\mu\textrm{g}$/ml at pH 3. Notably, about 8 fold and 4 fold increase of the specific activity of the enzyme were observed with the seedlings treated with 8$\mu\textrm{g}$/ml Na$_2$SO$_3$ at pH 5 and 2$\mu\textrm{g}$/ml Na$_2$SO$_3$ at pH 3, respectively. The effects of Cd and Pb on the peroxidase activities and chlorophyll contents were also examined. About 3.9 fold higher peroxidase activities were found at 0.03mM Cd, and the chlorophyll contents were reduced to 63% of the control seedlings. At 0.04mM Pb, 2.5 fold higher enzyme activities were found and the chlorophyll contents were reduced to 72%. Therefore, the increases of rice peroxidase activities might be involved in the defense mechanism of the cell against various environmental stresses such as Na$_2$SO$_3$, Cd and Pb. The effects of Cu and Fe, which are the inducers of oxidative stresses by the generations of reactive oxygen species, on the peroxidase activities were also investigated. About 57% and 65% activity losses were found at 0.5mM CuSO$_4$ and 0.5mM FeSO$_4$, respectively, and radical scavenger ethanol almost completely protected both inactivations. However, dimethyl sulfoxide, mannitol, thiourea and histidine showed different radical scavenging effects one another against Cu and Fe inactivation.
