The purpose of this study was to perform a kinematic analysis of the high jump techniques of the three men`s medalists at the 2011 IAAF Championships in Daegu (August 27-September 4, 2011), In particular, a three-dimensional coordinates method was used to analyze the last three strides before touchdown, the touchdown techniques, and the movements after takeoff toward the bar. An analysis of the, data for the biomechanical characteristics of the world`s best high jumpers could contribute to an improvement in the performance of a national high jumper. The first conclusion of the data analysis was that the arm movements of the gold medalist, J. Williams, had a single arm form, whereas the arm movements of the other medalists were a double arm form. Second, the difference in the knee joint angles upon touchdown and toe-off was 10˚. Third, J. Williams achieved his maximum CM height after takeoff (1.26m) using the maximum flexion of his knee joint. Fourth, the foot contact duration of A. Dmitrik (0.11 s) was the shortest among the medalists, and the ratio for his transformation of horizontal velocity to vertical velocity was the greatest (75.25%) among the three. Last, the maximum CM height of T. Barry was the greatest, and his foot contact duration was the longest.

Polybrominated diphenyl ethers (PBDEs) are a class of "brominated" (bromine containing) man-made chemicals used as flame retardant additives in plastics, foams, and textiles. PBDEs are found in various environmental contaminants in air, soil, sediment, and water, and 209 individual forms (congeners) of PBDE exist. Among these, 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) is the dominant congener found in the environment. Exposure to BDE-47 is now worldwide, and levels of BDE-47 have been detected in the blood of animals, including humans. BDE-47 can adversely affect the developmental system in both humans and animals. BDEs have structural similarities to polychlorinated biphenyls and thyroid hormones. However, recent studies have shown that BDEs may act as hormonal disrupting chemicals with detrimental effects. Therefore, a reliable assessment of BDE-47 toxicological action is required to understand the detrimental impacts of BDE-47 on human health. In this review, we overview recent studies on the distribution and potential toxicological effects of BDE-47 in humans and animals.

Purpose: We analyzed the role of TURB and definitive radiation therapy as curative treatment of muscle-invasive bladder cancer. Materials and Methods: From Jan. 1985 through Dec. 1992, 23 patients with muscle-invasive transitional cell carcinoma of the urinary bladder who were not candidate for radical cystectomy or chemotherapy were received TURB and pelvic external beam radiation therapy(external beam radiation, mean 6500 cGY, mean 8 weeks). T categorization was based on clinical examination assessing the computed scan and the transurethral biopsy. Results: Of 23 evaluable patients overall 2-year and 5-year survival rate following TURB and radiation therapy were 445(10/23) and 26%(6/23), respectively. Five-year survivals by clinical stage were 3(43%) of 7 with stage T3a, 2(29%) of 7 with stage T3b, and 1(11%) of 9 with stage T4. Overall complete remission and partial remission were achieved in 6(26%) of 23 patients and in 9(39%) of 23 patients, respectively. Complete remission by clinical stage was achieved in 4(57%) of 7 with stage T3a and in 2(29%) of 7 with stage T3b, and in 3(33%) of 9 with stage T4. Acute and self-limited complications of radiation therapy such as dysuria, diarrhea, and urinary frequency occured in 61% of the patients during the radiation therapy. Conclusions: Definitive radiation therapy after TURB is appliable bladder preserving modality in patients with muscle-invasive bladder carcinoma when they are not proper candidates due to general inoperability or due to the patient's preference.

Using confidential accounting data of executive-specific short-term bonus plans, we presents the extent to which executives manipulate earnings to maximize the present value of bonus plan payments. As such, this paper extends the works of other, Healy(1985). Like Healy, we find essential model evidence consistent with the hypothesis that managesr manipulate earnings downwards when their bonuses are at their maximum. Unlike Healy, we find essential model no evidence that managers manipulate earnings downwards when earnings are below the minimum ecessary to receive any bonus.

To construct a structure in rock, first of all, the mechanical behavior of the rock should be understood. Most of rocks in situ have contained mechanical weak planes which greatly influenced on the mechanical behavior of the rock. On this study, hard rock was used to investigate in influence of the weak plane on the peak strength and displacement behavior. The results were summarized as follows; 1. When the angle of a weak plane(α) was 30。, the lowest peak strength was appeared. And the peak strengths between 30。to 45。were increased with increasing angles of weak plane. But the anisotropy of peak strength by the angle of weak plane was not remarkable in the comparision with that of soft rock, Tuff. The reason is the influence of the angle of the internal friction of the weak plane. 2. Different from soft rock, the peak strength was higher α= 60。than 90。with the lowest rate of displacement (1㎛/sec) in case of hard rock. It shows that the peak strength of weak plane is chiefly influenced by coefficient of internal friction rather than cohesion.

The purpose of this study is to analyze the overall situation of how the elementary school-level physical education curriculum is organized and operated. For this purpose, five teachers in charge of elementary physical education were selected as research participants. Data were collected through questionnaires and telephone interviews, and inductive case analysis was conducted. In order to secure the authenticity of the data, it was reviewed among members and consulted with experts. As a result of the study, problems such as a curriculum without a teacher's philosophy, a curriculum without subject content, a curriculum without autonomy, an unprepared curriculum, and a curriculum inconsistent with organization and operation were raised in the school-level elementary physical education curriculum. As alternatives, the composition of the curriculum reflecting the teacher's physical education philosophy and the thoughts of the members, review of teacher education, establishment of educational infrastructure, and guarantee of practical autonomy were suggested. 이 연구는 초등학교 학교수준 체육교육과정이 어떻게 편성·운영되는가에 대한 전반적인 실 태를 분석하는데 목적이 있다. 이를 위해서 체육교과 전담교사 5명을 연구참여자로 선정하였 다. 질문지와 전화 면담을 통하여 자료를 수집하여 귀납적 사례분석을 하였으며, 자료의 진실 성 확보를 위하여 구성원간 검토, 전문가 협의를 거쳤다. 연구 결과, 학교수준 초등 체육교육과 정에서 교사철학 없는 교육과정, 교과내용 없는 교육과정, 자율권 없는 교육과정, 준비되지 않 은 교육과정, 편성과 운영이 일치하지 않는 교육과정 등의 문제점이 제기하였다. 대안으로는 교사의 체육철학과 구성원의 생각이 반영된 교육과정의 구성, 교사교육의 재검토, 교육인프라 의 구축, 실질적인 자율권의 보장 등을 제안하였다.

Considering the facing subject that the sound basic national economic condition is most important in the modern enterprises growth the function of self-finance like the depriciation is significant in efficiently keeping up the economic development, continuing the high growth and maintaining the strength of enterprises finance. Most enterprises, however, pay no heed to the fundamental function of depreciation by basly using this depreciation system as the unproper means of period profit instead of financial application for the investment finance source and economic development, so that the enterprises investment depends on outer-induced finance to make the strength worse. Accordingly, the depreciation is artificially accounted in the determination of method, useful life and scarp-value, and also applies for the custom of general accounting. Studying the maintenance status and tax law of the Complex depreciation system, the following results are obtained. 1) The useful life under the free depreciation system is only for the determination of depreciation rate, 2) It is doubtful whether or not the depreciation functions well as the finance source of surplus and devision fund because it is a loss without expense in cash. 3) It is problematic that tangible fixed asserts is put on 10%, and intangible fixed asserts 0%, uniformly. 4) The systematic complement of possible depreciation of fixed casserts closing related to production and sale in terms of mechanical establishment is necessary. 5) The systematic complement to solve the problem of depreciation determination is necessary. 6) The argument about the special depreciation between the enterprises Accounting and tax Accounting should be solved.

Organizations classified as non-profit institution have as their objective the furnishing of services of one sort or another on a non-profit, no-loss basis. The governing body of a nonprofit enterprise has the responsibility of carrying our the service objectives of the activity within the framework of the limitations surrounding its operations, efficiency of operation and compliance with legal and other restrictions are the basis premises of accounting for such organizations. A common misunderstanding of the term, "nonprofit", seems to imply that operations should be carried on at a loss"nonprofit"however, involved breakeven concept of operations, The basis idea is that the enterprise is organied to furnish services to some segment of the service without financial gain to the persons or groups who supplied the funds used in furnishing the service. In most case there is no requirement that the funds expended must be recovered and returned to the original supplier. A number of characteristics are common to the types of organizations which may be included in the nonprofit classification. Among these characteristics are the following: 1. Revenue is often restricted as to its use. 2. No private ownership of property is involved. 3. Permanent funds, held only to produce income, as well as expendable funds are ofter present. 4. The major purpose is to render services on a no-profit, no-lose basis. In certain activities financial profits may actually result, however, such profits and not provately distributable but insure solely to the benefit of the directing agency. 5. Management is not answerable to a group of investor owners but must report upon its steward ship of the funds entrusted to it to the general public on the supporting donors. 6. Generally these organizations are wholly or largely extempt from taxation.
