It is essential for future planning that governments and industry have a clear assessment of the quantities of petroleum available for production and quantities which are anticipated to become available within a practical time frame through additional field development, technological advances, or exploration. This paper describes the petroleum reserves classification and estimating methods based on the SPE/WPC (1997) definition. Reserves are those quantities of petroleum which are anticipated to be commercially recovered from known accumulations from a given date forward. Reserve estimating methods usually are categorized into analogy, volumetric and performance techniques. The performance techniques are subdivided into simulation studies, material balance calculations, and decline trend analysis. Reserve can be estimated using either deterministic or probabilistic methods. This paper can be helpful to understand petroleum reserve estimation and evaluate the reserves in oil & gas development projects properly.

The latest industrial machinery is usually used under the severe conditions such as high temperature, high pressure and high load because it needs the best efficiency. The austenitic stainless steels(SUS 316) are well suited for high temperature and high pressure service because of their creep resistance and high ductility. In this paper, in order to investigate the variation of fracture toughness of the specimens given repeat stress at 450℃, decreasing temperture of ductility, instrumented charpy impact test was carried out from-150℃ to 100℃. The results are summerized as follows ; 1. The fatigue life at 450℃ is reduced by 70 percent than that at room temperature. 2. When the specimens are damaged by the fatigue at 35kg/㎟ and at cyclic numbers with the same ratio on N_f, the difference between 450℃ and room temperature in hardness increasing ratio is 7%, and 5% at 30kg/㎟ 3. The maximum distance of work hardened zone by the fatigue damage at room temperature is larger than at 450℃. It means that the plastic deformation occurs easily because the yielding stress is lower at room temperature than at 450℃. 4. The fracture energy(E_f) decreases with the increase of nominal stress and rate of damage.

최근 정보통신기술의 발달에 따라 기업 교육훈련 체계가 전통적인 소집형 교육에서 e-learning으로 전환되고 있다. 기업교육의 궁극적인 성공은 교육을 이수하고 난 뒤 현업에 돌아가서 자신이 배웠던 교육내용을 실무에서 적극적으로 사용함으로써 전이성과를 높이는 데 있다. 본 연구는 기업교육의 전이성과에 영향을 주는 제 요인들을 살펴보는 것이 연구목적이다. 전이성과 결정요인으로 기업교육의 일차적 성과인 정서적 반응과 학습성과를 가정하고, 이들 간의 관계에 영향을 미치는 직무몰입의 매개효과를 실증 분석하였다. 이를 위하여 국내 기업교육 전문업체 C사와 직장인 재교육 교육기관인 K기관으로부터 최근 3개월에서 6개월 사이에 e-learning을 이수한 피교육자를 대상으로 설문조사를 실시하였다. 그리고 구조방정식모형에 의한 분석결과를 제시하고 토의하였다. 분석 결과, 직무몰입의 매개효과가 검증되었으며 분석 결과에 대한 해석 및 토론을 하였다. The development of information technologies has contributed virtual training as one of important education methods. E-Learning in firms provides trainees with more education opportunities in diverse ways. It has developed a range of innovative services with an one-stop solution of education within the electronic sector. Also under the e-learning environment, trainees can undertake customized training packages at anytime and any places. Moreover, information technology allows both the trainers and other trainees to be decoupled in any of the elements of time, Place, and space. This study explores the relationship between reaction/learning performance and transfer performance, and analyzes the mediating effect of individual characteristics on training effectiveness in e-learning settings. Based on the previous literature conducted on the traditional training environment, four sub-hypotheses are developed and tested by questionnaires survey data. The collected data have been analyzed by SPSS12.0 Results indicate that 1) reaction to the e-learning program are revealed as factor affecting the improvement of the transfer performance; and 2) mediating effects of personal characteristics(job involvement) are partially identified. The contribution and limitations of this research are also discussed with future studies.

This study was to find out calorie intake and body composition changes in accordance with weight loss of wrestlers. The wrestlers were divided three groups : no weight loss groups, 5∼7% weight loss group and over 7% weight loss group. And they were observed three : before weight loss, at measuring weight and before games. The following are the conclusion of this study: 1.The changes of calorie intake 1) Before weight loss, the percentage of the daily intake to the daily energy expenditure was 57.7% for the no weight loss group, 47.2% for the 5%∼7% weight loss group and 53.7% for the over 7% weight loss group. 2) The calorie intake of each group per meal: the no weight loss group intake 1,118kcal before weight loss, 760.9kcal before weight measurement and 1026.8kcal from after weight measurement to before games, and the 5∼7% weight loss group intake 955.4kcal before weight loss, 483.1kcal before weigh measurement and 880.4kcal from after weight measurement to before games, and the over 7% weight intake 959.3kcal before weight loss, 339.4kcal before weight measurement and 872.7kcal from after weight measurement to before games. 3) The ratios of calorie intake(protein : fat : glucose) : the no weight loss group showed 16.7∼35.1% : 20.8∼23.8% : 44.1∼60%, the 5∼7% weight loss group showed 15.5∼26.6% : 22.2∼23.7% : 50.6∼62.3% and the over 7% weight loss group showed 15.0∼30.2% : 19.6∼27,6% : 50.7∼59 4%. 2.The changes in body composition 1) After weight loss, weight and BMI changes in accordance with weight loss among groups showed meaningful differences in all circumstances : weight, before games versus at measuring weight and before weight loss versus before games.(p≤.001) 2) In the changes of total body water, protein, mineral, fat mass and %fat in accordance with weight loss among groups, when we compared those of before games with those of at measuring weight, we found that the over 7% weight loss group showed a meaningful increase over the no weight loss group.(p≤0.5) 3) In the changes within groups, though we found no meaningful difference, total body water, protein and mineral of before games were less than those of before weight loss, and fat mass and %fat of before games were higher than those of before weight loss. According to the results of this study, the wrestlers lost their weights intensively in three days before games by eating less and when lean body mass was restored, the level was lower than before weight loss. Therefore, these results intake the weakness of exercise capacity, long-term weight loss plan is more helpful than short-term weight loss, and for the enhancement of exercise capacity systematic plan and training of the weigh loss should be done.

고진공내의 데칸용매하에서의 요오드화 iso-프로필의 용해도를 8, 15, 25℃에서 니트로벤젠과 톨루엔이 존재할 때와 존재하지 않을 때의 두 경우에 대하여 각각 측정하였다. 데칸용매내에 니트로벤젠과 톨루엔이 존재할 때 요오드화 iso-프로필의 용해도가 존재하지 않을 때 보다 더 크고, 톨루엔과 요오드화 iso-프로필과의 상호작용이 니트로벤젠과의 상호작용보다 더 강하게 작용한다는 것을 알 수 있었다. 그리고 니트로벤젠과 톨루엔이 데칸용매내에 존재할 때 요오드화 iso-프로필과 니트로벤젠 및 톨루엔이 각각 불안정한 Complex를 형성한다고 생각되어 이 Complex를 여러 경우의 비율로 가정하여 계산해 본 결과 1 : 1 Comples를 형성한다고 보는 경우의 평형상수 K값이 비교적 일정한 값을 나타내었다. 그러므로 1 : 1 Complex 즉 ??과 ??이 용매속에 형성됨을 알았다. 또한 이 Complex의 생성에 대한 엔탈피, 자유에너지 및 엔트로피의 변화도 산출하였다. The solubilities of iso-propyliodide in decane on high vacuum were measured at 8℃, 15℃ and 25℃ in the presence and absence of nitrobenzene and toluene. When nitrobenzene and toluene exist in system respectively, the solubilities of iso-propyliodide in the presence of nitrobenzene and toluene are greater than in the absence, and the interaction of iso-propyl iodide with toluene is stronger than with nitrobenzene. In the presence of nitrobenzene and toluene, it could be thought that iso-propyl iodide forms unstable complex with nitrobenzene and toluene. The complex was assumed in various ways and it was evaluated that the equilibrium constant K value was relatively constant under the assumption of 1 : 1 complex. Thus, 1 : 1 complexes, ??과 and ?? are formed in the solution. Also, the changes of enthalpy, free energy and entropy for the formation of the complex were calculated.

The Orbital fracture which is often combined with midface fracture can cause decreased visual acuity, limitation of eyeball movement, diplopia, enophthalmos, etc. Traumatic orbital fracture causes change of orbital volume, results in diplopia and enophthalmos thus, accurate repositioning of displaced bone and reconstruction of orbital defect with autogenous materials(cranial, rib, iliac bone, cartilage and fascia lata) or alloplastic materials(gelatin film, polyglactin mesh, methylmethacrylate, Teflon, silicone, Supermid, hydroxyapatite and metal). The key point of reconstruction of orbit is accurate repositioning of displaced orbital floor, lateral, medial orbital wall and sufficient bonegraft in anatomical defect. As this cases, we obtained good results through transconjunctival and coronal approach who were required orbital reconstruction. Also, we accurately diagnosed orbital fracture with C.T., 3D model and good result for orbital reconstruction with sufficient parietal block bone graft during average 16.8 months follow-up.
