Purpose: The purpose of this study was to explore the barriers and solution of providing long-term care (LTC) services at home for the beneficiaries with mild dementia. Methods: The data were collected by interviewing three focus groups consisting of 10 home-visit nurses and analyzed through the analytic process by Morgan and Krueger. Results: The barriers of providing LTC services for clients were identified as follows: inadequateness of the current LTC model for elderly individuals with mild dementia and inappropriateness of the personal environment for home care. The solutions for these barriers were suggested as follows: building up a safe environment for home care and maintaining an appropriate standard utilization plan of LTC service. Conclusion: The current service model for the beneficiaries with mild dementia should be modified in order to provide comprehensive long-term care services based on their complex needs.

Validity of use of a Y-maze for determining a foraging strategy of cattle was investigated with the object of establishing a procedure of testing foraging strategies of large herbivores. Cattle were placed in a start box of a Y-maze, forced into either goal arm and allowed to consume half of the feed at the end of the arm. Then, cattle were returned to the start box and allowed to choose either arm in the second half of a trial. This time animals were allowed to deplete the feed in the goal arm they chose. A return to the previous arm was recorded a "stay" Choice of the other arm was recorded as a "shift". Shift strategy was not observed. Rather, their behavior appeared either random or stay. However, it might have been caused by inappropriateness of the application of the apparatus and/or the procedure used in the study of foraging behavior of rats. Although the existence of lateral preference was suggested, further study with an elaborated procedure will be necessary to investigate foraging strategies of cattle.

As construction industry is requiring competitive power and technique in national construction market with rapid fluctuation of construction environment and development, requirements upgrading performance in construction materials are increasing. But, national lightweight aggregate and lightweight concrete's inappropriateness when produced are also increasing. And there are not international standard of aggregates in using these construction materials because standards and characteristics of aggregate in each countries are different. Therefore, in this study, lightweight aggregate acquired due to wide range of use is tested and mixed for concrete to gain practicality and set the authorized manual in international. Also, basic data will be proposed to set a standard for concrete by analyzing lightweight aggregate characteristics. When lightweight aggregate absorptivity is high, concrete shows low strength and when it's density is low, concrete shows low weight of unit volume. Furthermore, compressive strength of lightweight aggregate is steep in first and longtime material age is tendency to cause low strength increasing rate.

Background : The purpose of this research was to evaluate the appropriateness of preoperative hospital days in a tertiary care hospital and to examine the reasons of the inappropriateness, so as to provide basic information and policy for enhancing appropriateness of preoperative hospitalization and benefit of patients and hospital. Methods : The subjects of the research were the 344 patients who received operation among discharged patients during January, 1996 in surgical departments including general surgery, neurosurgery, orthopedic surgery, plastic surgery and ophthalmology. Their medical records were reviewed and appropriateness of hospital days was evaluated by the Appropriateness Evaluation Protocol. Result : The results of evaluating the appropriateness of preoperative hospitalization showed that inappropriate hospital days were 80.8%. The reasons of inappropriate hospital stays were the tests or preparation which could be done in outpatient basis' followed by 'possible tests or preparation on the operation day' and 'cancelation of operation'. Conclusion : In order to shorten the inappropriate preoperative length of stay, it is recommended that lengthening of laboratory running time and doing most of tests necessary for operations on the outpatient basis prior to admission should be considered. In addition, the operation at the same day of hospitalization and usage of day surgery should be encouraged. Finally there should be changes in the inpatient management system and attitudes and behaviors of surgeons to shorten unnecessary preoperative and maximize the benefit for patients and hospital.

We evaluated the inappropriateness of metformin use in patients with type 2 diabetes and chronic medical conditions to identify the frequency of the prescription metformin in violation of the food and drug administration (FDA) black box warning. We reviewed medical records of 307 outpatients who received metformin at endocrinology department in a hospital setting between January 1, 2005 and August 30, 2009. Of the 307 outpatients, 25 discontinued treatment of metformin due to elevated serum creatinine level (Scr${\geq}$1.5 mg/dl in male, Scr${\geq}$1.4 mg/dl in female), cancers, and/or liver disease. 5 were lost to follow-up. 89 (29.0%) of the patients had cardiovascular disease, 54.1% for hypertension, 9.8% for liver disease, and 60 (20.8%) for chronic kidney disease. 12 patients (3.9%) with chronic kidney disease and/or elevated serum creatinine level, and 1 patient (0.3%) with lactic acidosis were contraindicated to metformin use. Metformin should be avoided in 7 outpatients (2.3%) with active hepatitis and 1 patient (2.6%) with liver cirrhosis. Of the 307 outpatients, 13 (4.2%) patients who received metformin at the first visit and 16 (8.7%) patients who received metformin at the last visit violated to black box warning. 8 (2.6%) of the patients were in precautionary conditions to metformin use. Adjusted mean difference of serum creatinine was -0.16 mg/dl [95% CI: -0.22 to -0.11 (p<0.05)] and adjusted mean difference of alanine aminotransferase was 4.46 IU/l [95% CI: 2.47 to 6.44 (p<0.05)] between the first visit and the last visit. Critical number of elderly patients who are at the high risks of drug-disease and drug-laboratory interaction is exposed to the inappropriate metformin use in violation of black box warning. The periodic evaluation of metformin use and monitoring prescription through drug utility review (DUR) system is needed to improve patients' safety and to reduce adverse drug events.

사망진단서의 상당수가 부적절하게 기록되고 있다. 이의 원인으로는 사망진단서 작성에 관한 교육의 부족과 사망진단서 작성자의 무관심 등에서 비롯된 것으로 보인다. 사망진단서 오류는 우리나라의 사망 환자 통계의 신빙성을 떨어뜨리고, 보건 정책 등에 올바르게 반영되지 못하는 결과를 가져오게 된다. 2005년 1월 1일부터 12월 31일까지 1년간 대구 소재 A병원에서 발급된 사망진단서 298건을 연구 대상으로 사망진단서의 오류를 조사하였다. 주오류중 사망기전만 기입한 경우 26건(8.7%), 경쟁 원인 기입은 28건(9.4%), 부적절한 진단은 34건(11.4%)이었다. 1개 이상의 주오류를 가진 경우는 88건(29.5%)이었다. 부오류는 시간 간격을 기입하지 않은 경우가 296건(99.3%), 직접사인과 선행사인은 기록하고 중간선행사인을 제외하였거나 직접, 중간선행, 선행사인에 같은 진단을 기입한 경우는 58건(19.5%), 한 칸에 2개 이상의 진단을 기입한 이중진단인 경우가 56건(18.8%) 등이었다. 오류가 없는 사망진단서는 88건으로, 전체 진단서 298건 중 29.5%밖에 되지 않았다. 사망진단서 작성의 정확성을 기하기 위하여 올바른 교육 프로그램 마련 및 교육의 강화가 절실히 요구된다.

Fashion, a means of communication, is the symbol conveying the social information and the individual identity. The opulence of material and the development of civilization make the sign of fashion variable and individual; especially, The importance of hair style among the today's sign of fashion, as a determinant element in judging each person's look is emphasized. Kitsch, based on the variety and the individuality is the manner of art in diverse hobbies. In addition, it enlarges the sphere of modern an, creates new open aesthetic world. Therefore, we need to understand the symbol of Kitsch aestetic represented in hair style, which is meaningful. The method of this study is quality analysis by means of semiology, aesthetics, Fashion artical, magazine, atc. To support this statement, we will study the form, a primary symbol, and the ideology, a secondly one in $\ulcorner$Mythologies$\lrcorner$ of Roland Bartes(1972). Then by means of the form and the ideology, we will try to recognize the myth, an essential symbol. The result of this study is following like these three points. First, the Kitsch patterns of representation in hair style use the accumulation by an excessive ornamentation; the inappropriateness by the lack of form, the disagreement, the unbalance, and the nonfunctional form; and finally, the amusement by the reconstruction, the exotic, and the satire. The above three is true to the Barthes's primary symbol-the form. Second, the anti-traditionality(including the lack of form, the disagreement, and the unbalance), the homesickness(including the reconstruction and the exotic), and the eclecticism(including the parody and the mixed imitation) are created as the ideology of the liberal artistic notion, different from the past outlooks on aesthetic. This is true to the Barthes's secondly symbol-the ideology. Third, the form and the ideology enable us to express our own thoughts and to recover the humanity, which is the primary purpose of Kitsch aesthetic. The Kitsch hair style, as we witness, does lead the varied and liberal aesthetic world, create its accessible value, and place the art of hair style in a higher status.
