중석은 우리나라에서 40여년간 개발되어 1951년 이후 세계 굴지의 중석 생산국의 하나로 등장 했으나 중석에 대한 광물학적및 지화학적인 지식은 이들을 다루고 있는 전문가에게도 극히 제한되어 이해되고 있다. 중석에 대한 광물학, 지구화학적인 활동특성, 중석광상의 특정과 광화작용의 지질적인 환경등에 관한 연구논문이 세계적으로 상당량 발표되어 있다. 일반적으로 잘 알려진 중석광물중 회중석과 흑중석은 일차광물로 회중석계열 및 흑중석계열 광물중의 하나에 불과하며 이외 이차광물은 극히 드물게 산출되나 이들은 중석광물을 탐사하는데 중요한 자료가 되기도 한다. 반면 중석에 대한 지구화학지식은 아직도 불완전하게 알려져 있고 지질과정에 있어 중석의 활동 특성은 연구단계에 있다. 최근 중석의 기초 지구화학연구가 많이 진전되어 여러 학자들에 의하여 그 자료가 정리되어 발표되고 있다. 중석광상을 보다 더 이해하고 앞으로 효율적인 탐사를 위하여 현재까지 알려진 중석에 대한 지구화학적인 기초연구와 중석광상에 수반되는 원소들을 요약한다.

PURPOSE. Articulation paper mark size is widely accepted as an indicator of forceful tooth contacts. However, mark size is indicative of contact location and surface area only, and does not quantify occlusal force. The purpose of this study is to determine if a relationship exists between the size of paper marks and the percentage of force applied to the same tooth. MATERIALS AND METHODS. Thirty dentate female subjects intercuspated into articulation paper strips to mark occlusal contacts on their maxillary posterior teeth, followed by taking photographs. Then each subject made a multi-bite digital occlusal force percentage recording. The surface area of the largest and darkest articulation paper mark (n = 240 marks) in each quadrant (n = 60 quadrants) was calculated in photographic pixels, and compared with the force percentage present on the same tooth. RESULTS. Regression analysis shows a bi-variant fit of force % on tooth (P<.05). The correlation coefficient between the mark area and the percentage of force indicated a low positive correlation. The coefficient of determination showed a low causative relationship between mark area and force ($r^2$ = 0.067). The largest paper mark in each quadrant was matched with the most forceful tooth in that same quadrant only 38.3% of time. Only 6 2/3% of mark surface area could be explained by applied occlusal force, while most of the mark area results from other factors unrelated to the applied occlusal force. CONCLUSION. The findings of this study indicate that size of articulation paper mark is an unreliable indicator of applied occlusal force, to guide treatment occlusal adjustments.

The object of International License Contract is technology. Technology is means to produce visible goods, which are human's intellectual creations such as Intellectual Property Right - patent, design, trademark- and Know-how. Unlike visible goods which decrease as being used, these technologies are possible to be produced expansively and develop additionally. Therefore, the way to make a contract of goods is a sales contract which transfers ownership while technology follows license contract which gives approval of use for a certain period. International license contract means that licensor has right to possess, allows licensee to use licensed technology for a fixed period and takes royalty. So there are various matters such as selection of the duration of a contract, confirmation of technology range, competition limitation, technique guidance and support, calculation of royalty, withholding tax between parties. This study examines licensor's grant of license and competition limitation. Intellectual property rights fundamentally give exclusive rights to the creator so the licensor use or dispose of his or her intellectual property rights at will. Technology transfer is possible through license contract because of this right. But licensor must exercise his or her intellectual property rights within a reasonable limit. It means, when licensor makes an unreasonable demand abusing his or her position, it is regarded as competition limitation clause and the deal itself may become null. Therefore, restraint on competition needs to be examined in detail as it influences on contract validity. Each country has their own competition laws for establishing a fair market order and inspection guide and guideline for judging whether there is any unfair act related to intellectual property rights. Judgment on intellectual property rights is subject the technology-introduced country's domestic laws and thus, contracting parties each need to precede opposite nation's domestic laws system.

We would like to suggest the guideline of use of materials of sexual education for adolescent in school by examining the status of use of materials and by evaluating the video materials frequently used. Survey was done by enquetes on status of use of materials of sexual education from school nurses in 190 primary, 44 middle and 50 high schools in Seoul, Kyonggi-do and Kangwon-do from August 1999 to February 2000. The frequently used 84 videotapes were evaluated on their contents. As for the status of use, 99.3% of subjected schools possessed the materials for sexual education. Decision of purchase was determined according to the review of contents (92.6%). Information about materials was received by the advertisement in newspapers or broadcasting (46.1%) or recommendation of peer teacher (32.4%). Videotape was most frequently used (64.1%) rather than books or CD. Teachers concerns on the materials were the educational content according to developmental stage of students (41.9%), content provoking interest (33.5%) and concrete guide for teacher (10.6%). As for the evaluation of the contents of videotapes, a subject of education was not described out of 46.6%. Videotape producer were mostly the Government-affiliated institutes or non-profit organizations (86.8%). The year of production was indicated from 41.7%. Running time range of 21-30 minutes was highest (55.9%). The price was marked in only one videotape. Subjects of contents were general sexual education (34.5%), sexual violence or sexual harassment (21.4%), pregnancy and contraception (14.2%) and AIDS and sexually transmitted diseases (8.3%) and dating and adolescent change (4. 8%), and etc (11.9 %). According to above results, we suggested that materials for sexual education should be completed with a description on the subjected group, summary of content, information on the tape producer, year of production, running time and sale price.

Clamping force of a high strength bolt is reduced by a certain period of time after the initial set-up. In case of special treatments on faying surfaces such as protective coating, clamping force is relaxed more severely. Tests for slip critical joints subject to various faying surface parameters were conducted. Five different surface treatments were tested including mill scale surface, blast surface, rust surface and coated surfaces. Each specimen was composed of F10T M20 of high strength bolts and steel plates. Based on the result of slip coefficient test, blast treatment surface showed 0.59, rust treatment surface showed 0.54 and inorganic zinc treatment surface exhibited 0.44. Clean mill treatment surface and red lead paint treatment surface were 0.23, 0.21 respectively. It is identified that the slip coefficient in Korean structural design guide should be determined for various surface conditions. Subsequently from long term relaxation test of ASTM A 490 high strength bolts, relaxation of no-coated surfaces such as blast, clean mill, rust treatment, the loss of initial clamping load was 10.5%, 13.6% and 7.9% for 1,000 hours, while the loss of initial clamping force was reached as 15.0%, 18.7% more than the required redundancy 10% in case of inorganic zinc and red lead painted treatment. It is required that the limit of relaxation on coated faying surface should be established separately for various surfaces.
