This study was conducted to determine the effects of horticultural therapy (HT) program using hydroponics on work adjustment skills of students with mental retardation. Based on the critical role transitional model and special education curriculum for agriculture, especially hydroponics, HT program (total 22 sessions) using hydroponics procedure for Lettuce (Lactuca sativa L. 'Asia Heuk Romaine') was developed. Fourteen (10 males, 4 females) graded $1^{st}$ to $2^{nd}$ with intellectual disabilities were recruited from a special education class in a high school located in Inchon, Korea and then a special farm for hydroponics in Inchon, Korea was offered for the HT program. The students with intellectual disabilities participated in the HT program for 4-month (from September to December of 2011, twice a week, approximately 60 minutes per session). Before and after the HT program, the McCarron assessment neuromuscular development, emotional behavioral checklist, interpersonal negotiation strategies, and KEPAD picture vocational interest test were performed by the teachers and horticultural therapists. As the results, the students significantly improved motor performance (p = 0.002), emotional behavioral strategies (p = 0.00), and interpersonal negotiation strategies (p = 0.05). However, no significant difference between before and after the HT program for vocational interest was observed. In conclusion, the HT program using hydroponics, consists of simple and easy tasks so that it would be applicable for the students with intellectual disabilities positively affected to work adjustment skills by improving the motor performance, emotional behavioral strategies, and interpersonal negotiation strategies. Additionally, HT programs using hydroponics with various kinds of vegetables are required to develop and to apply in practical settings for improving work adjustment skills.

Purpose : The patients who visited this department for pulmonary disease and need CT scans for Follow-up to observe change of CT value, evaluation of image quality and decrease of radiation dose as change of kVp. Subjects and Methods : Subjects were the patients of 20 persons visited this department for pulmonary disease and Somatom Sensation 16(Semens, Enlarge, Germany) was used. Measurement of CT value as change of kVp was done by setting up ROI diameter of 1cm at the height of thyroid, aortic arch, right pulmonary artery in arterial phase image using 100 kVp, measuring 3 times, and recorded the average. CT value of phantom was measured by scanning phantoms which means contrast media diluted by normal saline by various ratio with tube voltage of 80 kVp, 100 kVp, 120 kVp, 140 kVp and recorded the average of 3 CT values of center of phantom image. In analysing radiation dose, CTDIVOL values of the latest arterial phase image of 120 kVp and as this research set that of 100 kVp were analyzed comparatively. 2 observers graded quality of chest images by 5 degrees (Unacceptable, Suboptimal, Adequate, Good, Excellent). Results : CT value of chest image increased at 100 kVp by 14.06%~27.26% in each ROI than 120 kVp. CT value of phantom increased as tube voltage lowered at various concentration of contrast media. CTDIVOL decreased at 100 kVp(5.00 mGy) by 36% than 120 kVp(7.80 mGy) in radiation dose analysis. here were 0 Unacceptable, 1 Suboptimal, 3 Adequate, 10 Good, 6 Excellent in totally 20 persons. Conclusion : Chest CT scanning with low kilo-voltage for patients who need CT scan repeatedly can bring images valuable for diagnose, and decrease radiation dose against patients.

Objective : Delayed ischemic neurologic deficit(DIND) is one of the major complications following aneurysmal subarachnoid hemorrhage(SAH). However, the correlation between angiographic vasospasm(AV) and DIND after SAH is not precisely known. The authors investigated the timing, incidence, characteristics of DIND, and analyzed correlation between AV and DIND. Patients and Methods : A series of 126 patients with SAH and performed cerebral angiography which, confirmed anterior circulation aneurysm, admitted to between January 1996 to December 1998, were studied retrospectively. A comparative analysis between group 1(G1) in which AV patients presented with DIND, and group 2(G2) patients did not DIND, were done. AV was graded according to location, distribution and degree. Location of vasospasm was classified as basal type(BT), distal type(DT). BT was involved horizontally and include the bilateral carotid systems, proximal middle cerebral artery(MCA) and proximal anterior cerebral artery(ACA). DT was involved vertically and include the MCA branches as they become vertically or posteriorly oriented and the ACA distal to the anterior communicating artery. BT and DT all defined ether as localized type(LT) or combined type(CT). Distribution of vasospasm was classified as type I, type II and type III. Type I represents the involvement of bilateral carotid systems and bilateral anterior cerebral artery, type II was designed as one carotid system without involving anterior cerebral artery, and type III when only some portions of the anterior cerebral artery were involved, bilaterally. Degree of vasospasm was classified as mild(less than 25%), moderate(between 25-50%), severe(greater than 50%), and those were determined by comparing the caliber of the artery in vasospasm to that of the nearest area of apparently normal vessel. Results : The incidence of AV & DIND was 57/126(45.2%), 29/126(23.0%), and timing of DIND was 9 days(${\pm}4.1$) after initial hemorrhage. As for the location, BT was seen in 12 cases(40.0%), DT 11 cases(36.7%) and CT 7 cases (23.3%), respectively. Where as G1, BT was seen 5 cases(18.5%), DT 5 cases(18.5%) and CT 17 cases(63.0%), respectively in G2. CT AV was more correlated with DIND than LT AV(p<0.05). For distribution, type I was seen in 16 cases(59.2%), type II 4 cases(14.8%), type III 7 cases(25.9%) in G1 where as type I was seen in 7 cases(23.3%), type II 10 cases(33.3%), type III 13(43.3%) in G2. Type I AV was well correlated with DIND unlike to type II or type III(p<0.05). As for the degree, mild was seen in 4 cases(14.8%), moderate 14 cases(51.9%), severe 9 cases (33.3%) in G1, and mild 16 cases(18.5%), moderate 11 cases(36.7%) and severe 3 cases(10.0%) in G2. Moderate to severe type AV was well correlated with DIND(p<0.05). Conclusion : These results indicate that it may be possible to predict DIND according to careful analysis of location, distribution, degree of AV in patients with aneurysmal SAH.

Purpose: To evaluate the association of subacromial bursa inflammation with acromial shape and shoulder pain in subacromial impingement syndrome. Materials and Methods: 24 cases with subacromial impingement syndrome were reviewed. Eighteen patines were males and six females(mean age: 58.3 yrs). During arthroscopic operation, the specimens were taken from subacromial bursa with arthroscopic knife($1{\times}1$ cm size). The shape of acromion were classified according to Bigliani grading system. The shoulder pain of patients was graded with visual analog scale (VAS). The grade of inflammation was classified to the pathological three grade system (mild, moderate, severe) by pathohistological 8 factors. Results: Of total 24 cases, 9 cases were the pathological grade I and 15 cases were grade II. None was grade III. In the 9 cases of pathological grade I, 6 cases were the radiologic grade II of acromial shape and 3 cases were grade III. In the 15 cases of pathological grade II, 5 cases were the radiologic grade II and 10 cases were grade III. The VAS was 7 point at pathological grade I and 8 point at grade II. As the statistical analysis, the pathological grade of subacromial bursa was associated with acromial shape (p<0.05), but not associated with pain of patient (p>0.05). Conclusion: Our study suggests that pathological grade of subacromial bursa inflammation was associated with acromial shape. But pathological grade of subacromial bursa inflammation was not associated with shoulder pain of patients.

The achievement of notable social reoforms attained during the period of 19th and 20th centuries needlessly speaking remodelded the social environmental into several different patterns such as :1) high industrialization 2) propensity to consume 3) up graded overall social stands. Accordingly the industrial world of the but-tons too established the mess production syhstem by breaking from convention of hand-craft work of 17th century. The raw materials used in the production line on buttons during the 20th century are almost all-kind of materials one can possibly named including cheap plastic which enabled production lines to produce cheaper but higher productivities of the buttons being produced, The design (incused design) used in the 19-20h centuries are : men landscape, sports features, birds, livestocks, bugs, or geomatric features, tec, 1, The classification o f the buttons by materials Techniques shapes colors marking (Incused design) used in the productionof buttons in the England United States of America Laska Italy france Denmark Japan and India are categolizzed as : natural raw materials and syntetical resines. 1) Of the natural raw materials used are : Matal Enamel Iodine Agate, Coral, Green jade(Jasper) Granite, Wood, Ivory, Horn and bone etc. 2) The sythetical resin used in the button in-dustries are : Artificial jewell glass Acrylic material Styroform Celluloid and Nylon etc. 2. The thecnique quoted in producing buttons are hand craft work inlay work precision casting press mosic dye etching, processing, engraving and embossed carving etc. 3. The major designs used in the buttons in -dustries are : Round shape however elliptical column angular and edge shape often used. 4. The colors used are : The multi-colors were highly used than mono-colored materials such as : Adjoining Color and Contrast Color. The highest consideration to be considered in choosing the colors for the buttons are harmonization and matching factor with the garment or dresses to be wore. 5. The major design(incused design) on the buttons are embodiment and the design were also used in order of abstractive-combination abstractive with has offers much surprising. The button industries during the 19th and 20th centuries were not only the determination factors those can judge the value of self-pride of Nation and which were far beyond the in-dustrial arts in those days but also highly refelected and influenced by cultural sense ideology and self-pride of the Nation of those period. The followings are details of the role of the buttons categolized in the order of functional ornamental and symbolical aspects : 1. The functional role : The functional role of the buttons were simply designed for dress how-ever the buttons beyond from this role of function now a days. 2. The ornamental role : The ornamental role of he button beyond from this role of the button were effectuated by : 1) shape materials colors 2) technique locations size and design (incused design) 3) The ramaterials used for buttons shall not be over looked because it is highly depends on the taste sense and combination of harmony with the garment to be wore. 4) The color of the buttons are made well contrasted with the color of garments just as in the case of other artistical area such as matchs with the color of garment of contrast with brigtness of colors contrasted as complementary color and so and so. 5) The technique being adoped are: precision casting press handcraft inlay work etching mosic etc,. Since the buttons are no longer a simple catching devise used to fasten together the different part of the dress but now it has formed own and occupied the independent role in the garment or dresses location can be de-termined and varying depending on the ideas of designers. The size of the buttons has no specific limits, However the variation has widely dependined on the entire circumperence rhythm contrast harmonization of the garments. 3. The symbolical role : Since the button is no longer a just a simple devise for catching and fastening device used fastening together the different part of the garments but now were built a independent area as major part of the Garment and well reflected all kinds of occupations political background cultural as-pect etc. on the buttons. The design of buttons in the western circles are more simplified but they are polished looks and their techniques of manufacturing are comination of both machanis and handcraft. The colors used in the buttons are pretty well harmonized with garment(dress). Almost all kind of materials can be used in the but-tons however materials used in the buttons are : Bone of livestocks ivory, turtle shell are no longer used because the prevention of cruely of animal. On the contraly the level of buttons indus-try of Korea is far to reach and catch up with the level of western circles. It is highly suggested therefore the but-tons industrial field of Republic of Korea shall place and encouragement in producing beter industrial environment of the buttons based on the traditional and cultural aspect of republic of Korea to produce both manufacturing of qulified and best designed and colored buttons.

Silicone hydrogel contact lenses developed as a continuous-wear modality are now used as a daily-wear contact lenses. The purpose of this study was to investigate the clinical performance in a group of successful long-term wearers of conventional hydrogel contact lenses when refitted with daily wear $O_2OPTIX$ silicone hydrogel lenses. Sixty-two wearers ($30.7{\pm}19.9$ months of prior lens wear) among sixty-five soft lens wearers refitted with $O_2OPTIX$ silicone hydrogel lenses were participated in this study finally. Subjective symptoms were scored and objective signs were graded using CCLRU scales during the study period. 98% of subjects were successfully refitted with the one base curve of $O_2OPTIX$, and 33.9% of subjects were needed more or less lens powers compared with their habitual lenses. Subjects reported a concurrent reduction in dryness, redness and tiredness compared with their habitual lenses and both subjective and objective evaluations showed that dryness, tiredness, itchiness, bulbar and limbal hyperemia were decreased and significantly decreased particularly for those subjects with greater baseline symptoms (p<0.0001). But corneal staining was increased and was seen in many subjects during the study (p<0.0001). Refitting existing soft contact lens wearers with silicone hydrogel contact lens could result in a decreased in dryness, redness and tiredness, particularly more effective for those subjects with greater baseline of those symptoms. When patients using conventional hydrogel materials switch to a silicone hydrogel material, the potential for increased corneal staining should be considered and over-refraction should be needed to give a best vision.

Purpose : This study aimed to examine the excretion of various urinary proteins in children with a history of urinary tract infection(UTI), with or without vesicoureteral reflux(VUR) or reflux nephropathy, and to identify means of predicting the severity of VUR or the presence of reflux nephropathy as indicated by these markers, and to know how these markers are changed after resolution of VUR. Methods : We studied 30 children with previous UTI, without VUR and renal scarring(group I), 12 children with VUR, without evidence of renal scarring(group II), and 34 children with VUR and renal scarring(group III). 24-hour or 12-hour urine ${\beta}_2$ microglobulin(${\beta}_2$ MG), microalbumin and N-acetyl-${\beta}$-D-glucosaminidase(NAG) were measured in each child. Urinary protein excretions were analyzed according to the degree of VUR(mild VUR : a grade reflux I-III, severe VUR : a grade reflux IV-V). Cases of bilateral VUR were graded by the higher grade of reflux detected. A total of 46 children with primary VUR were followed. Among these patients, VUR was completely resolved in 16 children. Voiding cystourethrography(VCUG) and DMSA scan were performed every year. Values for urinary markers were estimated every year. Results : 24 or 12 hour urine microalbumin and NAG excretions were significantly increased in group III compared to group I(microalbumin : $27.7{\pm}26.0mg/gCr$ vs $15.0{\pm}10.7mg/gCr$, P<0.05, NAG : $15.2{\pm}18.7U/gCr$ vs $3.4{\pm}2.2U/gCr$, P<0.05). Urinary ${\beta}_2$ MG excretions were not significantly different between groups. Urinary NAG excretions were elevated in the group of children with severe VUR compared to mild VUR($26.8{\pm}27.1U/gCr$ vs $7.6{\pm}3.8U/gCr$, P<0.05). After resolution of VUR, urinary microalbumin and NAG excretions were decreased(P<0.05). Conclusion : Urinary microalbumin and NAG may be useful clinical indicators to predict the presence of reflux nephropathy and the resolution of VUR. Especially, urinary NAG excretions may be used as a possible method to predict the severity of VUR.

This study was conducted to investigate the effects of graded levels of a herbal recipe(Herb Mix $Gold^{(R)}$, Herb BIO Co.) supplemented to a commercial layer diet. The Herb Mix $Gold^{(R)}$ is an improved recipe of Herb $Mix^{(R)}$, fortified with Angelica gigas, Discorea japonica and Ligusticum jeholense. A total of 720 layers (Hy-Line Brown) of 45 wks old were assigned to one of six treatments; control, 0.2% Herb $Mix^{(R)}$, 0.1%, 0.2%, and 0.3% Herb Mix $Gold^{(R)}$, and 6 ppm Avilamycin. Each treatment had 6 replicates of 20 birds each housed in 2 birds cages. Birds were fed diets and water ad libitum for 5 weeks. Hen-day egg production was significantly (P<0.05) different among treatments. Herb Mix $Gold^{(R)}$ 0.2% treatment showed the highest egg production followed by Herb Mix $Gold^{(R)}$ 0.3%, Herb $Mix^{(R)}$ 0.2%, Herb Mix $Gold^{(R)}$ 0.1%, Avilamycin 6 ppm and the control. Hen-housed egg production, egg weight, soft and broken egg ration, feed intake, feed conversion ratio, shell strength, shell thickness, shell color index, Haugh unit and yolk color index were not significantly different among treatments. Nor was cfu of Cl. perfringens and E. coli and Lactobacilli in the small intestinal content significantly different among treatments. The number of white and red blood cells, hemoglobin, heterophil, lymphocyte, thus heterophil to lymphocyte ratio were not significantly modified. It was concluded that Herb Mix $Gold^{(R)}$ at the level of 0.2% in the layer diet improves laying performance.

A total of one hundred and ninety five nutritionists selected based on population scale in high schools in Gyunggi Province were questioned about utilization of eggs in school meals. Almost half of those nutritionists have utilized eggs in school meals $3{\sim}5$ times per month. Most frequent cooking methods of eggs were boiled eggs. Eggs obtained from food distributors and egg distributors were 80.8% and 13.2%, respectively. Also, the nutritionists in middle population area prefer to purchase graded eggs. The most frequently occurring problems in cooking eggs were egg shell braking and related food safety. The present study revealed that egg is good for school meals, but various menus for easy cooking are yet to be developed.

In the age of global communication, more human exchange is extended at the grass-roots level. In the old days, language policy and language planning was based on one nation-state with one language. But high waves of globalizaiton have allowed extended human flow of exchange beyond one's national border on a daily basis. Under such circumstances, homogeneity in Japan may not allow Japanese to speak and communicate only in Japanese and only with Japanese people. In Japan, an advisory report was made to the Ministry of Education in June 1996 about what education should be like in the 21st century. In this report, an introduction of English at public elementary schools was for the first time made. A basic policy of English instruction at the elementary school level was revealed. With this concept, English instruction is not required at the elementary school level but each school has their own choice of introducing English as their curriculum starting April 2002. As Baker, Colin (1996) indicates the age of three as being the threshold diving a child becoming bilingual naturally or by formal instruction. Threre is a movement towards making second language acquisition more naturalistic in an educational setting, developing communicative competence in a more or less formal way. From the lesson of the Canadian immersion success, Genesee (1987) stresses the importance of early language instruction. It is clear that from a psycho-linguistic perspective, most children acquire basic communication skills in their first language apparently effortlessly and without systematic and formal instruction during the first six or seven years of life. This innate capacity diminishes with age, thereby making language learning increasingly difficult. The author, being a returnee, experienced considerable difficulty acquiring L2, and especially achieving native-like competence. There will be many hurdles to conquer until Japanese students are able to reach at least a communicative level in English. It has been mentioned that English is not taught to clear the college entrance examination, but to communicate. However, Japanese college entrance examination still makes students focus more on the grammar-translation method. This is expected to shift to a more communication stressed approach. Japan does not have to aim at becoming an official bilingual country, but at least communicative English should be taught at every level in school Mito College is a small two-year co-ed college in Japan. Students at Mito College are basically notgood at English. It has only one department for business and economics, and English is required for all freshmen. It is necessary for me to make my classes enjoyable and attractive so that students can at least get motivated to learn English. My major target is communicative English so that students may be prepared to use English in various business settings. As an experiment to introduce more communicative English, the author has made the following syllabus design. This program aims at training students speak and enjoy English. 90-minute class (only 190-minute session per week is most common in Japanese colleges) is divided into two: The first half is to train students orally using Graded Direct Method. The latter half uses different materials each time so that students can learn and enjoy English culture and language simultaneously. There are no quizes or examinations in my one-academic year program. However, all students are required to make an original English poem by the end of the spring semester. 2-6 students work together in a group on one poem. Students coming to Mito College, Japan have one of the lowest English levels in all of Japan. However, an attached example of one poem made by a group shows that students can improve their creativity as long as they are kept encouraged. At the end of the fall semester, all students are then required individually to make a 3-minute original English speech. An example of that speech contest will be presented at the Convention in Seoul.
