본 연구는 레진시멘트의 레진인레이에 대한 접착 시 접착제 혹은 primer의 사용이 결합력에 영향을 미치는지 평가하기위해 시행하였다. 직경 5 mm,높이 4.5 mm의 원기둥 형태로 제작한 레진인레이(Tescera, Bisco, USA)의 표면을 1000번,1500번 그리고 2000번 사포로 주수 하에서 연마하여 평편한 면을 형성한 후 레진인레이의 표면에 sandblasting을 시행한 후 표면에 1분 동안 silane을 도포하였다. 2군으로 나누어 한 군은 대조군으로,다른 한 군은 표면에 동일한 제조사의 접착제나 프라이머를 도포한 후 중합하였다. 레진인레이 상에 3 mm 직경의 구멍이 형성된 아크릴판을 고정하고,구멍에 레진 시멘트를 주입하여 경화시켰다. 레진 시멘트는 Panavia-F(Kyrary), Varolink-II(Ivoclar-Vivadent), RelyX Unicem (3M ESPE),Duolink (Bisco)와 자가중합형인 Multilink(Ivoclar-Vivadent)를 사용하였다. 제작된 시편을 만능물성시험기에 위치시고 전단결합강도를 측정하였다. 측정 결과 접착제나 프라이머를 도포한 군은 대조군에 비해 전단결합강도가 증가하였다 (p < 0.05). 하지만 Variolink-II와 Panavia-F는 전단결합강도의 차이를 보이지 않았다. 대조군에서는 각 레진 시멘트 간에 전단결합강도의 유의한 차이를 보였으며 (p < O.O1),Variolink-II가 가장 높은 결합강도를 보인 반면,자가중합형인 Multilink가 가장 낮은 결합강도를 보였다. 하지만,접착제나 프라이머를 도포한 군에서는 각 제품 간에 전단결합강도의 차이를 보이지 않았다. 이상의 결과 이원중합형이나 자가중합형 레진시멘을 이용하여 레진인레이 부착 시 silane 처리 후 접착제나 프라이머의 도포가 결합 강도의 증가를 위해 필요하리라 사료된다. This study analyzed the influence of dental adhesive/primer on the bond strength between indirect resin composite and the resin cement. Seventy disc specimens of indirect resin composite (Tescera Dentin. Bisco) were fabricated. And bonding area of all specimens were sandblasted and silane treated for one minute. The resin cements were used with or without application of adhesive/primer to bonding area of indirect resin restoration: Variolink-II (Ivoclar-Vivadont): Exite DSC, Panavia-F (Kuraray): ED-Primer, RelyX Unicem (3M ESPE): Single-Bond. Duolink (Bisco): One-step. Mulitlink (Ivoclar-Vivadent): Multilinh Primer. Shear bond strength was measured by Instron universal testing machine. Adhesive application improved shear bond strength (p < 0.05). But Variolink II and Panavia-F showed no statistically significant difference according to the adhesive application. With the above results. when resin inlay is luted by resin cement it seems that application of dental adhesive/primer is necessary in order to improve the bond strength.

To study the effects of corticosteroids to the bone tissues, author grouped young(3 weeks affter birth) and adult ICR mouse by dosage, injected intramusculaily prednisolone, a series of corticosteroids, to posterior leg during 6 weeks per day, obtained femurs and tibias, measured the lengths of tibias and femurs. The portions of the distal end of tibial crests were cross-sectioned, general H-E stain was perpormed. The adjacent distal portions of femoral neck were sectioned longitudinally, observed endosteal surface by scanning electron micrscope The results were followings: 1. The adult group injected by large dosage (0.56mg/100g body weight/day) and the young group injected by small dosage(0.14mg/100g body weight/day) from 3 weeks after birth were significantly shorter than the normal group according to statistics. And the adult group injected by small dosage (0.14mg/100g body weight/day) was not different from normal group according to statistics. 2. In the light microscopic sutdy, the adult group injected by large dosage decreased in bone mass of compact bone severely, the adult group injected by small dosage changed a little grade. The young group injected by small dosage from 3 weeks after birth was not severe in bone change, but bone thickness decreased. 3. In the scanning elctron microscopic study, the adult group injected by large dosage and the young group iniected by small dosage from 3 weeks after birth decreased in trabeculae. The trabeculae of the adult group injected by small dosage were decreased slightly. 4. Integrating above all, the changes by prednisolone injection osteoporosis, of young period were more severe than those of adult, too.

서해의 아산만, 천수만과 영광 근해, 남해의 삼천포 근해 및 동해의 영일만에서 otter trawl로 민태를 채집하여, 계절에 따른 밀도 분포, 체장 및 연령 조성을 분석하였다. 영광근해에서는 민태의 평균밀도가 1,147개체/10,000㎡로 높은 생물량을 보였고, 저어류 군집을 우점하였다. 천수만에서는 평균밀도가 94개체/10,000㎡, 아산만과 삼천포에서는 이보다 낮아 8-24개체/10,000㎡였다. 영광 근해에서 서해의 북쪽 혹은 남해의 동부로 갈수록 평균밀도는 감소하였으며, 영일만에서는 한 개체도 채집되지 않아 동해 연안에는 분포하지 않는 것으로 보인다. 이 어류는 봄에 연안에 출현하기 시작하며 해역에 따라 봄, 혹은 여름에 최대 밀도를 보였다. 봄과 여름에 채집된 개체는 Ⅰ, Ⅱ 및 Ⅲ세의 성어들이었으며, 영광과 삼천포에서는 여름부터 유어들이 채집되기 시작하였다. 가을에는 미성어가 주를 이루었다. 이 결과로 미루어 산란을 위하여 봄에 내만으로 몰려온 성어는 산란을 마친 후 외해로 넓게 분산되며, 많은 유어들은 월동하기 위하여 외해로 이동하는 늦가을까지 내만에서 자라는 것으로 추정된다. The distribution, and length and age compositions of Johnius belengeri were studied using samples collected by an otter trawl from the five different coastal waters of Korea : Asan Bay, Cheonsu Bay, waters off Yeongkwang and Samchonpo, and Yeongil Bay. This fish showed a high density of 1,147 individuals/10,000㎡ and predominated in abundance of the demersal fish in the coastal water off Yeongkwang. The mean density was 94 individuals/10,000㎡ in Cheonsu Bay and 8-24 individuals/10,000㎡ in Asan Bay and in the water off Samchonpo. Few fish were collected from Yeongil Bay. J. belengeri occurred from spring to autumn in the study area and showed a relatively high density in spring or in summer. The fish collected in spring and in summer composed of adults of age group Ⅰ, Ⅱ and Ⅲ. Some juveniles began to occurred in the waters off Yeongkwang and Samchonpo from summer. The fish collected in autumn consisted mainly of the fish of age group 0. It implies that the adults after spawning moved out from the embayments for feeding, but the young fish stayed and grew in the embayments until late autumn when they migrated to the offshore water for wintering.

The AN-AA copolymer-Cu(Ⅱ) and Amidated AN-AA copolymer-Cu(Ⅱ) complex were the most stable in the pH range of 9. The morphology of Cu(Ⅱ) complex and CuxS-induced had changed into compact form. The thermal stability for Cu(Ⅱ) complex and CuxS-induced had been determined through DTA and TGA measurement. As result, it has been observed that thermal stability for Cu(Ⅱ) complex were stabilized less than that of copolymer. The Cu(Ⅱ) complex exhibited surface resistivity around 10Ω㎝ when modified iodine in acetone. The resistivity was significantly affected by the amounts of added cupric chloride, iodine and results were statisfactorily obtained by adding more than 20wt% of Cupric chloride and about 1.0wt% iodine. The optimum condition for the introducing of CuxS was at the CuSO₄concentration of 30g/ℓ and the reaction time of 3hrs. The CuxS-induced electrical conductivity of copolymer was higher by order of 10 than that of the Cu(Ⅱ) complex.

Objectives : Since the publication of Korean Medication Algorithm Project for Major DepressiveDisorder (KMAP-MD) in 2002, there has been a substantial need for a revision due to rapid progress in the pharmacological management of depressive disorder. We revised KMAP-MD 2002 and developed the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) 2006. Methods : We developed a questionniare for surveying the opinion of experts on pharmacotherapy of depressive disorder. The questionnaire consisted of 4 parts ; 1) treatment of non-psychotic depressive disorder, 2) treatment of psychotic de-pressive disorder, 3) treatment according to clinical subtypes and drugs choice considering adverse effects, and 4) treatment of depressive disorder in women. The questionnaire was completed by the review committee consisting of 101 experienced Korean psychiatrists. It is composed of 22 questions, and each question includes 54 sub-items. We classified the expert opinionto 3 categories (the first-line, the second-line, or the third-line) by χ²-test. Results : For depressive disorder with psychotic features, most reviewers prefer the combination of antidepressant and atypical antipsychotics. Electroconvulsive therapy and the combination of antidepressant and typical antipsychotics were the second-line treatment. Among antidepressants, venlafaxine was the most preferred, and SSRI and mirtazapine followed. Among atypical antipsychotics, quetiapine, risperidone and olanzapine were the most preferred, in this order. In patients who have no response to the first-line treatment, many reviewers recommended switching to another antidepressant or adding another atypical antipsychotics Conclusion : For severe depressive disorder with psychotic features, the combination of antidepressant and atypical antipsy-chotics was preferred for the first-line treatment. These results suggest that the medication strategies of depressive disorder are rapidly changing and reflects the recent studies and clinical experiences.

「韓國倫理」의 敎育的 價値志向

朴仁熙,宋海永,金元述 경북대학교 1992 논문집 Vol.24 No.-

Since the opening of this country in 1876, we had kept our own cultural orientation and this cultural orientation had been working as principle of our individual and community life. But this orientation became degraded through the colonial policy of Japan and the set-up of military government by U. S. A and U. S. S. R, and also came to be deformed after the division of the country. From these reasons, it follows that modern Korean Ethics must tend to creativly modify the cultural orientation, which we aimed since 1876, and that Korean Ethics must be based on this fact. This is the question at issue and the object of this paper, For the settlement of the question, this paper develops the following details. First, the concept of Korean Ethics is defined on the level of cultural specificity and universality, and the orientation of Korean Ethics is explaned with relation to that of Korean Culture. Second, we had considered the education of Korean Ethics dividing our modern history into the opeining the country, the colonization, the military government of two powers and the post-establishment of two Korea. Third, the value that Korean Ethics must aim is discussed with reference to man, society and nation. In conclusion, it is argued that with the succession of our cultural orientation, Korean Ethics must be established by way of national consensus, and that through the educative efforts it must be interiorized towards the members of our society.
