This study attempts to analyze research Quality about home economics and education, based on the studies in the Journal of Korean Home Ecomics Education. The purpose of this study is to investigate the recent studies in hem economics and find out the desirable direction of it. The findings of study are as follow: While the numbers of articles appeared in The Korea Association of Practical Arts Education and Korean Home Economics Education Association are increasing, The Korean Home economics Association does not show the increase the number of articles. According to the historical changes and distribution, the majority was teaching-learning method and teaching materials. Also, from the point of view in research thesis, there were more articles in home economics and education than any others, In addition, among the various types of research, survey was most frequently used. There was significant differences of the sizes of groups according to the different journals, but the one group research was most frequent and one certain research area was dominant. The teams consist of two people showed the highest ratio, and junior high and high school were the most frequently researched institutions. Generally, it is hard to find research grant. Though there is much difference in numbers of references based upon various journals, almost all articles cited reference date not only from Korean articles, but also from international articles.

The meniscal cyst of knee joint is a rare disease, and the discoid meniscal cyst has not been reported in Korea. We report 3 cases of the discoid meniscal cyst confirmed by MRI and arthroscopy. In physical examination, all cases have tenderness of the knee joint. One has palpable mass of knee joint and the other one has limitation of knee motion with knee flexion contracture of 10 degrees and positive McMurray test at external rotation of the knee. All cases are complete discoid meniscus, which are, one medial discoid meniscus and two lateral discoid meniscus through MRI. We confirmed horizontal tear of meniscus in all cases and the location of meniscal cysts are anterior hem of meniscus in one and body of meniscus in two. We could get excellent results in all 3 cases that return to normal knee range of motion.
Purpose : The purpose of this study was to evaluate the arthroscopic findings of the transplanted human allogenic meniscus including MRI changes at follow up. Materials and Methods : From Oct. 1999 to Jun. 2002, nine patients underwent arthroscopic evaluation at follow-up. We used nonirradiated cryopreserved meniscus allograft for 6 cases and fresh-frozen for 3 cases. We used bone-plug method for medial meniscus and bone-bridge method for lateral meniscus to fix the transplanted meniscus. The average follow-up time was 13 months. We evaluated the result by lysholm score, MRI and second-look arthroscopic finding. Results : The second-look arthroscopy after allogenic meniscal transplantation revealed that grafts were well incorporated with surrounding capsular tissue. But one case showed wear on the post horn and the other case which was operated at other local clinic showed tear of the anterior hem due to non-anatomic placement of bone bridge. There was improvement of average Lysholm score form 64 to 87. Conclusion : Second-look arthroscopy revealed excellent incorporation of the allograft with firm attachment and early clinical results are satisfactory. But further studies are necessary to assess whether meniscal transplantation can prevent progressive degenerative changes.
The lastest concepts in bonding are "total etch", in which both enamel and dentin are etched with an acid to remove the smear layers, and "wet dentin" in which the dentin is not blown dry but left moist before application of the bonding primer. Ideally, the application of a bonding agent to tooth structure should be insensitive to minor contamination from oral fluids. Clinically contaminations such as saliva, gingival fluid, blood and handpiece lubricant are often encountered by dentists during preparation of a restoration. The aim of this study was to evaluate the effect of contamination by hem-ostatic agents on shear bond strength of compomer restorations. One hundred and ten extracted human maxillary and mandibular molar teeth were collected. The teeth were cleaned from soft tissue remnant and debris and stored in physiologic solution until they were used. Small flat area on dentin of the buccal surface were wet ground serially with 400, 800 and 1200 abrasive paper on automatic polishing machine. The teeth were randomly divided into 11 groups. Each group was conditioned as follows: Group 1 : Dentin surface was not etched and not contaminated by hemostatic agents. Group2 : Dentin surface was not etched but was contaminated by Astringedent (Ultradent product Inc., Utah, U.S.A.). Group3 : Dentin surface was not etched but was contaminated by Bosmin (Jeil Phann, Korea.). Group4 : Dentin surface was not etched but was contaminated by Epri-dent (Epr Industries, NJ, U.S.A.). Group5: Dentin surface was etched and not contaminated by hemostatic agents. Group 6 : Dentin surface was etched and contaminated by Astringedent. Group7 : Dentin surface was etched and contaminated by Bosmin. Group8 : Dentin surface was etched and contaminated by Epri-dent. Group9 : Dentin surface was contaminated by Astringedent. The contaminated surface was rinsed by water and dried by compressed air. Group10 : Dentin surface was contaminated by Bosmin. The contaminated surface was rinsed by water aud dried by compresfed air. Group 11 : Dentin surface was contaminated by Epri-dent. The contaminated surface was rinsed by water and dried by compresfed air. After surface conditioning, F2000 was applicated on the conditoned dentin surface. The teeth were thermocycled in distilled water at $5^{\circ}C\;and\;55^{\circ}C$ for 1000 cycles. The samples were placed on the binder with the bonded compomer-dentin interface parallel to the lmife-edge shearing rod of the Universal testing machine(Zwick 020, Germany) running at a cross head speed of 1.0mmimin. There were no significant differences in shear bond strength between groups 1 and group 3 and 4, but group 2 showed significant decrease in shear bond strength compared with group 1. There were no significant differences in shear bond strength between group 5 and group 7 and 8, but group 6 showed significant decrease in shear bond strength compared with group 5. There were no significant differences in shear bond strength between group 5 and group 9, 10 and 11.
The objective of this research is to unveil the dynamic changes of the trends in wedding dresses during the 20th Century. The studies were carried out in two forms; firstly by observing the actual wedding dresses worn by people at that time, and secondly by conducting formative comparisons between those dresses with the ones appeared in movies corresponding to that period. Movies provide an invaluable insight into the era's wedding dresses fashion trends since they function as intimate bridges in connection with the time's audience, and the visible imageries accurately reflect the characteristics embedded within that time frame. As there are no precedent studies regarding this topic, this thesis can serve as vital research data for the wedding dress industry. Research data regarding the actual wedding dresses were collected from books and museum web sites. The object of movies were films produced before World War II that contained both the background settings of the 20th Century and wedding dresses, of which photographic imageries were captured. Research analysis was then conducted by merging these data with findings from relevant books and internet materials. The results of the thesis are as the following: The 1900s was an extension of the 19th Century's popular fashion trend which can be characterized as the S curve silhouettes of the Edwardian period when long trains and long veils symbolized wealth and social power. In the 1910s, high waist silhouettes with soft wrinkles were prevalent as attire suitable for active mobility with practical functionality were highly regarded. During the 1920s, the flapper style became the dominant trend. Hem lines of the skirts were curled in the form of the scallop and laces were the most widely used raw materials. By the 1930s, wedding dresses that reinterpreted the glamorous sheath lines, practical two piece styles, and retro-styles became predominant. The 1940s saw the advent of ready-made wedding dresses made of synthesized materials; practical military style suits and casuals sometimes substituted the wedding dresses. And although the wedding dresses in the movies were primarily costumes to express the personalities of the characters, they were also reinterpreted as manifestations of the formative characteristics of each relative period that pursued very distinct and diverse features.
This study was carried out to analyze the quality change of mackerel treated extracts of Diospyros kaki, Teuceriun veronicoides and Zanthoxylum schinifoliun during storage to develope the preparation methods for high quality of salted mackerel. The mackerel treated with Z schinifoliun extract was lowest pH change among group. Titration acidity of mackerel was increased during storage at $4^{\circ}C\;and\;25^{\circ}C$. The changes of acid value (AV) of mackerel were lower treated herbal extracts at early storage than those in control group (5.79 meq/kg) at $4^{\circ}C$. Acid values were increased in all group at $25^{\circ}C$ during storage. Peroxide value (POV) was 10 meq/kg in the salted Mackerel. Increasing of peroxide values was lower in the salted mackerel during storage. Contents of volatile basic nitrogen (VBN) were increased during storage, and were lower in group treated herb extracts than in control group. Total viable cells of mackerel were more in groups treated hem extracts at early storage than in control group, but less in groups treated herb extracts during storage than in control group.
Purpose: Many hemostatic agents and dressings have been tested with variable degree of success. Chitosan has a positive charge, it attracts red blood cells, which have a negative charge. Our goal is to test the efficacy of new developed chitosan-based hemostatic materials in providing durable hemostasis in a high-flow arterial wound model. Methods: We compared each group with SD rats motality tests and in vitro blood compatibility test by blood clotting index (BCI). We devided the SD rats into 6 groups (N =15) by type of hemostatic agents. A: 100% nonwoven chitosan (degree of the deacetylation: 90%). B: 50% N-acetylation on nonwoven of chitosan gel (degree of the deacetylation: 50%). C: 60% N-acetylation on nonwoven of chitosan ge (degree of the deacetylation: 40%)l. D: Cutanplast$^{(R)}$. E: HemCon$^{(R)}$ F: Gauze. In vivo test, a proximal arterial injury was created in unilateral femoral arteries of 90 anesthetized SD rats. Each materials was made same size and thickness then applied to the injury site for 3 minutes. In vitro test, we compared each group with BCI in human blood. Results: In vivo test, group A showed lower motality rate of 46% than any other groups, Group B and C showed lower motality rate of 60% than group D and E's motality rate of 66%. In vitro test, BCI of group A ($30.6{\pm}1.2$) and B ($29.3{\pm}1.0$) were showed nearly about group D ($29.1{\pm}1.8$) and E ($27.4{\pm}1.6$). Group C ($37.1{\pm}2.0$) showed higher BCI than group A and B, it means group C decreased blood clotting. Conclusion: In conclusion, this study suggests a newly developed chitosan-based hemostatic materials induced durable hemostasis and increased blood clotting, and are considered as effective biologic hemostatic agents.
A curd yogurt was prepared by fermenting milk added with skim milk powder and purple sweet potato by culture of 5 types of lactic acid bacteria(Lactobacillus delbruekii sub. sp. lactis, Streptococcus lactis, acidity, number of viable cell, stability of purple sweet potato's pigment and keeping qualify. Among the organisms tested, the acid production and number of viable cell by the culture of L bulgaricus remarkably increased for the first 12 hem which showed 1.04${\times}$10$\^$9/ CFU/mL in number of viable cell and 4.22 In pH where as fermentation by the culture of B. bifidum was slow. After 36 hours of incubation which showed 3.3 ${\times}$ l0$\^$8/ CFU/mL in number of viable cell and 5.1 in pH. In stabilities of purple sweet potato anthocyanin pigment n fermentation, yogurt by B. bifidum was found to be most stable followed by Leuc. lactis, L. delbruekii sub. sp. lactis, L bulgaricus, but yogurt by St. lactis was not stable. When curd yogurt added with Purple sweet Potato was kept at 2∼3$^{\circ}C$ for 14 day, its keeping quality(pH, titratable acidity, number of viable cell) was relative good except product by L. bulgaricus was found to be decreased most of viable cell. After 2 weeks of keeping, pigment of yogurt was decreased by B. bifidum, stable by L. delbruekii sub. sp. lactis.

This study attempted to develop a bodice prototype that is the basis for the production of upper body clothing for 20s plus-size women who have distinct characteristics from women with general body types. Through this, it was intended to provide basic data necessary for the development of plus-size women's clothing, which is revitalizing the market due to the increase in the obese population. Through the first evaluation of appearance and abdominal pressure, patterns such as moving the side neck, adding the amount of armhole dart, and adding the amount of sagging were modified. Through the second evaluation, corrections such as vertical side lines, reduction of the neck of the back center line, and adding the amount of armhole darts were performed. Through the third evaluation, the final pattern drafting method was developed by vertically modifying the side line and adding the amount of back armhole darts. In the case of 20s plus-size female body types, a drafting method distinguished from the general body type was required in the method of setting the side and hem due to the protrusion of the abdomen. This study can be said to be meaningful in that it proposed a bodice prototype drafting method suitable for the body type of 20s plus-size women. In the follow-up study, it is thought that the wearability should be evaluated through actual garment wearing.
Purpose : Pain is the most serious symptom that cancer patients experience. About $60{\sim}90%$ of advanced cancer patients and four million patients worldwide, according to the WHO statistics, are reported to suffer from cancer pain. Although about $70{\sim}80%$ of the pain could be controlled according to the pain control principles, to our regret, only $30{\sim}40%$ are managed appropriately. This research was aimed to (1) investigates the prevalence of pain among cancer patients, (2) compare patients' perception of pain with physician's recognition and (3) evaluate appropriateness of the doctor's prescription of analgesic. Materials and Methods : Patients with advanced or terminal cancers admitted at department of internal medicine of Seoul National University Hospital for at least 7 days were enrolled. A questionnaire for the patients and the physicians in charge were given and the answers were compared for each other. We also examined their medical records and the physician's orders. Results : Total 59 patients were enrolled. Among them, 43 patients answered the questionnaire, and 27 patients (62.8%) suffered hem cancer pain. The survey also showed that physicians underestimated the severity of pain, overlooked frequently analgesic prescription principle, and that as the patients' pain became severe, the less adequate was pain managements. Conclusion : For cancer patients, pain was frequently overlooked, and treatment still inadequate. Based on this evidence, it seemed that more active practice and education about evaluation and management of cancer pain are needed.
