Although a majority of patients with splenic rupture present acutely, up to 15% present with a delayed rupture days to weeks following a substantial abdominal injury. The mortality for patients presenting with acute splenic rupture is approximately 1% whereas that associated with delayed rupture approaches 15%. Although many cases of delayed splenic rupture have been reported, the majority of those reports present delayed splenic rupture associated with an underlying systemic disorder such as liver or kidney disease, or another hematologic disorder. We found a delayed splenic rupture case that documented the normal spleens of young healthy soldiers after trivial abdominal trauma, and we have had successful treatment experience with delayed rupture of a normal spleen after trivial trauma. Therefore, we want to review the literature and discuss the phenomenon of delayed rupture of the spleen following trivial trauma.

Objective : The purpose of this study was conducted to find treatment of forward head posture and shoulder instability with proprioceptive neuromuscular facilitation concept. Methods : This is literature study with books, seminar note and international course. Results : Forward head posture and shoulder instability has related each other. Forward head posture will make muscle instability, weakness and stiffness on neck and shoulder girdle. It will make pain also. Important muscle are suboccipital muscle, omohyoid muscle, sternoclaidomastoid muscle, scaleni, pectoralis minor, levator scapular and digastric. Conclusion : Treatment of the forward head posture and shoulder instability is provided. It is that treatment of stiff muscle with eccentric muscle work, muscle elongation, muscle strengthening at the structure level and at the functional level for daily activities.

The evaluation of thermal properties of actinide oxide fuels is a problem of high importance for the development of new generation reactors. In the present study, an expression obtained for n-dimensional Debye functions is used to derive a simple analytical expression for the specific heat capacity of nuclear fuels. To test the validity and reliability of this expression, the analytical expression is applied to $UO_2$, $NpO_2$, $ThO_2$, and $PuO_2$. It is seen that the formula was in agreement with the experimental and theoretical results reported in the literature.

Acute rupture of the tibialis anterior tendon is rare, but the diagnosis is often delayed when it occurs. Acute rupture of the tibialis anterior tendon is often caused by minor trauma or it occurs spontaneously. Therefore, the diagnosis is more likely to be delayed. Among ruptures of the tibialis anterior tendon, longitudinal ruptures are less common and difficult to diagnose. Thus far, there are no reports of ruptures of the tibialis anterior tendon caused by direct trauma in Korea. This paper reports a case of chronic longitudinal tear of the tibialis anterior tendon caused by trauma in a 50-year-old male patient with no specific history of the disease, along with a review of the relevant literature.

Primary malignancies of hard palate are rare, espicially adenocarcinoma of minor salivary gland in hard palate. The clinical stage of the tumor and its histologic grade at the time of treatment were significant predictors of survival. A 33-year-old woman was diagnosed with stage II, polymorphous low-grade adenocarcinoma of the hard palate and treated with surgery. We thougt that she would have excellent prognosis. After that, there was no definite evidence of recurrence during 3 months. Since then, the patient herself decided to discontunue follow-up. 9 years after that she came to the hospital due to both submandibular mass without any sign of local recurrence. CT scan and biopsy of the mass revealed multiple cervical metastatic adenocarcinoma without distant metastasis and the histologic findings were similar to that of the primary hard palate adenocarcinoma. So, we present this case with the review of literature.

The purpose of this study was to investigate the food sanitation awareness and performance of foodservice industry employees. Based on a literature review, a questionnaire was developed to identify the food sanitation education, experience, knowledge, and food sanitation practices of the employees. A total of 376 Korean food industry employees participated, and there were 344 usable questionnaires. In the analysis of food sanitation knowledge, the statements "clip fingernails short and do not use nail polish", and "if feeling sick, even with a minor cold, speak to your supervisor immediately", had the highest and lowest percentages of correct answers, respectively. In assessing employee sanitary management practices, many correctly acknowledged "clip fingernails short and do not use nail polish" and "wash hands after using the toilet", which received high scores; however, "use hands to pick up ice" and "if feeling sick, even with a minor cold, speak to your supervisor immediately" had low scores. The sanitary knowledge and practice levels of the employees were not significantly different according to gender, age, work area, job title, or duration of duty. Among the surveyed industries, employees of special restaurants had the least sanitary knowledge(p<0.05) and practice scores(p<0.001). Employees who had worked for $1{\sim}3$ years presented the least sanitary management practice level scores(p<0.05).). In addition, college students and participants without hygiene educational experience showed the least levels of sanitary knowledge(p<0.01). Scores for sanitary management practice were higher when hygiene education was regularly conducted more than once per month. Employees showed significantly higher knowledge and sanitary management practice levels when they were required to use a sanitary checklist(p<0.001), and employees who were trained in HACCP had significantly higher sanitary checklist scores(p<0.05). In foodservices that applied HACCP, the employees showed higher knowledge and sanitary management practice levels(p<0.001).

Earthquake Resistant Design Philosophy seeks (a) no damage, (b) no significant structural damage, and (c) significant structural damage but no collapse of normal buildings, under minor, moderate and severe levels of earthquake shaking, respectively. A procedure is proposed for seismic design of low-rise reinforced concrete special moment frame buildings, which is consistent with this philosophy; buildings are designed to be ductile through appropriate sizing and reinforcement detailing, such that they resist severe level of earthquake shaking without collapse. Nonlinear analyses of study buildings are used to determine quantitatively (a) ranges of design parameters required to assure the required deformability in normal buildings to resist the severe level of earthquake shaking, (b) four specific limit states that represent the start of different structural damage states, and (c) levels of minor and moderate earthquake shakings stated in the philosophy along with an extreme level of earthquake shaking associated with the structural damage state of no collapse. The four limits of structural damage states and the three levels of earthquake shaking identified are shown to be consistent with the performance-based design guidelines available in literature. Finally, nonlinear analyses results are used to confirm the efficacy of the proposed procedure.

본 연구는 2000~2006년의 기간 동안 발생한 코스닥기업 인수합병결정의 성과를 측정하고 그 성과에 대한 횡단면분석을 통해 기업지배구조가 합병성과를 설명할 수 있는지 검토하였다. 본 연구를 통해 지분변수 등 기업지배구조 변수들이 합병성과의 횡단면 차이에 대해 상당한 설명력을 지니고 있음을 알 수 있었다. 본 연구의 시사점을 좀 더 구체적으로 서술하면 아래와 같다. 첫째, 지분변수 중에서 임원 지분이 대주주 지분변수, 지분 5% 이상 대량보유자의 지분과 기관투자자의 지분 등 외부 투자자의 지분보다 합병성과에 긍정적으로 영향을 미치는 결과로 나타났다. 둘째, 임원 지분 이외에 중요한 외부 투자자로 인식되는 외국인 지분의 경우, 그 자체로서는 기업합병의 성과에 큰 영향을 미치지 않은 것으로 나타났다. 이것은 선행연구와 달리(김희석 조경식 2006), 코스닥시장에서 외국인지분의 경우, 합병성과에 영향력이 없음을 알 수 있다. 또한, 소액투자자들도 내부지분과 같이 영향력이 큰 것으로 나타났으며, 이것은 합병이라는 특정한 사건이 투기적인 성향을 보이는 소액주주들에게 단기적으로 호재로 작용했을 가능성도 상존하기 때문이라 고 판단되며, 비교적 기업에 대한 정보가 부족한 소액주주들에게 합병으로 인한 시너지 효과가 발생하여 가치상승으로 이어질 것이라는 막연한 기대심리가 소액주주들의 지분이 증가한 원인으로 작용했을 수 있다. 셋째, 기존연구와 달리, 임원 지분과 같은 내부 투자자들의 지분율이 합병의 성과를 설명하는 유의한 변수로 나타났다. 이것은 코스닥시장의 규모가 유가증권시장보다 작기 때문에 소액투자자들처럼 소수임원으로도 통제가 가능하기 때문인 것으로 판단된다. 본 연구의 실증분석 결과는 전체적으로 기업합병의 성과에 기업지배구조가 일정부분 영향을 미치고 있음을 시사하고 있다. 소액투자자들이 코스닥시장 지배구조에 일정부분 영향을 미치는 결과는 기존 연구와 달리 새로운 연구결과라 할 수 있다.
