The mechanical and electrical properties of the pressureless annealed SiC-$TiB_2$ electro conductive ceramic composites were investigated as functions of the transition metal of $TiB_2$. The result of phase analysis for the SiC-$TiB_2$ composites by XRD revealed $\alpha$-SiC(6H). $TiB_2$, and YAG($Al_5Y_3O_{12}$) crystal phase. The relative density showed the lowest 84.8% for the SiC-$TiB_2$ composites added with 39vol.%$TiB_2$. Owing to crack deflection, crack bridging and YAG of fracture toughness mechanism, the fracture toughness showed the highest value of $7.8\;MPa{\cdot}m^{1/2}$ for composites added with 39vol.%$TiB_2$ under a pressureless annealing at room temperature. The electrical resistivity of the SiC-27vol.%$TiB_2$ composites was negative temperature coefficient resistance(NTCR), and the electrical resistivity of the besides SiC-27vol.%$TiB_2$ composites was all positive temperature coefficient resistance(PTCR) in the temperature range of $25^{\circ}C$ to $700^{\circ}C$.

${\ulcorner}$Diagnosis and Treatment of pregnancy in Synopsis of Golden Chamber${\lrcorner}$ stated about pregnancy nausea, stomachache, discharging blood, urine disadvantage, note and quickening uncertainty that appear during pregnancy. When diagnose pregnancy, taking a serious view pulse(脈診). If Soyakmaek(小弱服) appears in Cheokmaek(尺脈), diagnose by pregnancy. Pregnancy nausea is reaction that often appear in pregnancy beginning. Light symptoms are treated naturally even if do not treat, heavy symptoms should treat certainly because can arrive for inheritance influencing to embryo. If spleen and stomach cause lack of Youngwi(營衛) harmorny losing function, used Gyejitang (桂技揚) Because spleen course stomach is weak, so, because there are been a lot of cold liquids, if vomiting catches continuously, used Geonganginsambanhahwan(乾薑附子半夏九). When treat pregnancy stomachache because Yang(陽) is weak, it is cold and make to be warm by Bujatang(附子楊) in case have a stomachache. Because Chungimmaek(衝任脈) weak and cold, use Gyoaetang(膠艾揚) in case there are stomachache and bleeding. Because liver and spleen do not harmonize, use Dangguijakyaksan(當歸芍藥散) if stomachache and vertigo occur. ect. There is no contents that foster embryo, but I am thought by something affected greatly at future generations.

All of the disease which was referred in ${\ulcorner}$Diagnosis and Treatment of the Woonded, Carbuncle, intestinal infection and acute eczema in Synopsis of Golden Chamber${\lrcorner}$ are belong to surgery. Woonded in this chapter, specially, come under in case occur by metal, and spoke that this thing is metal wounded(金瘡). I am considered by something to use Wangbulryuhaengsan(王不留行散) in wound that is not festered, Baenongtang(排膿湯) and Baenongsan(排膿散) in wound that is festered. Carbuncle is one of Venus festering nature file that happen in skin and muscle because blood does not circulate with flag and part's flare, calorification, pain, puffiness are characteristic. Carbuncle is agreed with concept of inflammation of modern medicine. When treat carbuncle, without using surgery medical treatment, used together internal medicine surgery medical treatment. Intestines carbuncle(腸癰) is come in inflammation in abdominal cavity as kind of inflammation, partiality peritoneum festering disease round present cecum as one of inside carbuncle. I think, when treat intestines carbuncle, in case cold and moisture become stasis and heat is less, Uiibujapaedoksan(薏苡附子敗毒散) can be used. Independently of festering, Daehwangmokdantang(大黃收丹湯) can be used in case heat and extravasated blood become stasis. Saliva ulcer on the vulva is comes in impetigo In Case of young child, and is come in Venus eczema in case is general. Prognosis of saliva ulcer on the vulva widespread thing can treat by arm, leg at Lips region, but it does not treat to grow at Lips region from limb, and treatment uses Hwangryunbun(黃連粉)

This study is the third partial study of the 'A Bibliographical Study of the Toegye.' The contents of the study is divided into three chapters as following : In the first chapter, the authorship of Hsin-ching-fu-chu(心經附註) is described Hsin-ching(心經) was edited by Chen-Te-Hsiu(眞德秀), a scholar of the Sung Dynasty (1178-1235A.D.). He selected several articles on Hsin Study(心學) from classics of ancient China, with the view of spreading of Hsin thought of ancestor. Hsin-ching-fu-chu is an annotated work of Hsin-ching, which was edited by $Ch'\^{e}ng-Min-Ch\^{e}ng$(程敏政). $Ch'\^{e}ng-Min-Ch\^{e}ng$ was a scholar of the Ming Dynasty (died 1499 A.D). His annotation of Hsin-ching was according to the edition of Tuan-Ping (端平) 1st (1234 A.D.). Hsin-ching-fu-chu which was first published in 1492 A.D., by his student, named Wang-Tsu(汪祚). In the second chapter, the editions of Hsin-ching-fu-chu which was published in Korea before 1566 A.D., when Toe-gye's postscript was written, are described. In Korea, three editions were published. The first was published before 1523 A.D. in, kwang-ju(光州), by the wooden plate block. The second was published ca 1564 A.D. in Pyeong-yang(平壤), by the wooden plate, too. These two editions have remained. The last was published ca 1564 A.D., in Hae-ju(海州), but the method of printing couldn't be found out because I have not been able to get the book itself and records on the printing. In the last chapter, facts on Hsin-ching-fu-chu related to Toegye are described. Toegye found Kwang-ju edition of Hsin-ching-fu-chu in 1533 A.D., at Seong-gyun-gwan(成均館) in Seoul. He acquired the book from his friend. He read and studied very hard and remembered all the text. Also, he taught the Hsin-ching-fu-chu to his pupils and guided the reading of Hsin-ching-fu-chu to his followers and student. He read many proof sheets of the new publication of Hsin-ching-fy-chu, correcting then on detail and making notes on them.

Located in the southwestern part of Korea, the Yong San Gang river flows generally northeast to southwest, and because of the specific location, topography and climate, the basin area is subject to recurrent drought and flood damages. To eliminate the cause of such damages and ensure an increase in the farm income by means of effective irrigation supply and increased cropping intensity, efforts are being made to speed up implementation of an integrated agricultural development project which would include construction. of an estuary dam and irrigation facilities as well as land development and tidal reclarnation. In formulating a basin development project plan, it is necessary to study a series of long-term runoff data. The catchment area at the proposed estuary damsite is 3,471$\textrm{km}^2$ with the total length of the river channel up to this point reaching 138km. An analysis of runoff in this area was carried out. Rainfall was estimated by the Thiessen Network based on records available from 15 of the rainfall observation stations within the area. Out of the 15 stations, Kwang Ju and Mok Po stations were keeping long-term precipitation records exceeding some 60 years while the others were in possession of only 5-10 years records. The long-term records kept by those stations located in the center of the basin were used as base records and records kept by the remaining stations were supplemented using the coefficient of correlation between the records kept by the base stations and the remainder. The analyses indicate that the average annual rainfall measured at Kwang Ju during 1940-1972 (33 years) amounts to 1,262mm and the areal rainfall amounts to 1,236mm. For the purpose of runoff analysis, 7 observatories, were set up in the middle and lower reaches of the river and periodic measurements made by these stations permitted analysis of water levels and river flows. In particular, the long-term data available from Na Ju station significantly contributed to the analysis. The analysis, made by 4-stage Tank method, shows that the average annual runoff during 1940-1972 amounts to 2,189 million ㎥ at the runoff rate of 51%. As for the amount of monthly runoff, the maximum is 484.2 million ㎥ in July while the minimum is 48.3 million ㎥ in January.

The aim of teaching writing is not to memorize a single piece of knowledge but to acquire higher thinking that could be related to other fields using learners' various reading experiences and schemata. Among several strategies or techniques to write well, it is recommended to use a mind-map technique. A mind-map software applies the mind-map technique into computer for learners to study autonomously. However, the mind-map software is not common in educational fields yet and there are only few studies on the effect of it. Therefore, this study analyzed various curricula to extract the elements of writing and developed a mind-map software program which was applied and tested. As a result, the writing program using the mind-map software was effective in promoting learners' motivation and lowering anxiety. It also improved learners' competence of writing such as understanding, analytic thinking, creativity, ability to organize, and expression.

This study examined physiological activity of aronia chung with or without aspartame. High sugar content of food is recognized to induce chronic disease including diabetes and obesity. Sugar was replaced with aspartame to develop low-sugar aronia chung containing 0%, 25%, 50% and 75% aspartame based on sugar content of control in the study. Sweetness was the similar in the chungs with 0%, 25% and 50% aspartame but it was lower in the chung with 75% aspartame. pH was the highest in aronia chung with 75% aspartame as 2.95. Total phenolic content was the highest in aronia chung with 50% aspartame but it was not significantly different with 75% one. Flavonoid content increased with addition of aspartame and it was the highest in the chung with 75% aspartame as 206.60 ㎍ QEAC/mL. Reducing power also showed the same aspect with flavonoid content. However DPPH radical scavenging ability was the highest in aronia chung without aspartame and lowest in the chung with 75% aspartame. This result implies that the addition of aspartame could sustain the sweetness and improve the physiological activity of food at the same time although there is some limitation.

The objective of this study was to investigate the consumption pattern of snacks-containing trans-fatty acid in adolescents living in the Kwang-ju area of Korea, and to analyze the relevance toward their eating behaviors, body composition, nutrient intakes, and consumption frequency of snacks-containing trans fatty acid. A survey questionnaire was developed in order to investigate general environmental factors, eating behavior, nutritional knowledge, and the consumption frequency of snacks-containing trans fatty acid. A total of 312 middle school students were surveyed. The collection rate was 97% and ultimately 282 cases were analyzed. Anthropometric measurements, body composition data, and nutrient intakes were also collected. The consumption frequencies for snacks-containing trans-fatty acid were negatively correlated with food behavior scores (p<0.01) however, pocket money and snack intake frequency per day were positively correlated with consumption frequency. Also, snack consumption frequency had some correlation with the subjects' anthropometric measurements and body composition data such as total body water (p<0.01), body protein (p<0.01), body minerals (p<0.01), and skeletal muscle mass (p<0.01). Finally, the consumption frequency of snacks-containing trans fatty acid was significantly correlated with calcium intake (p<0.05), it also showed correlations with vitamin A, retinol, ${\beta}-carotene$, and folic acid intake, although statistical significance was not verified.
