김인배,김순호,강민철,윤인택 釜山大學校生産技術硏究所 1998 生産技術硏究所論文集 Vol.55 No.-

6082 Al합금의 미세조직 및 기계적 성질에 미치는 시효처리의 영향을 시차주사열분석기, 투과전자현미경 및 미소경도 시험을 통하여 조사하엿다. 170℃, 9시간의 시효열처리에 의해서 118Hv의 최대경도값이 얻어졌으며, 이는 GP zone과 β'상의 석출에 의한 것이었다. 최대경도 이후의 경도 감소는 완만한 감소를 나타내었는데 이러한 결과는 β'에서 β로의 변태속도가 매우 늦다는 것을 의미한다. 이 합금의 석출과정은 GP zone →불안정 hcp Mg₂Si(β') →평형 fcc Mg₂Si(β)이었다. The effect of aging treatment on the microstructures and mechanical properties of 6082 aluminum alloy was investigated by differential scanning calorimetry, transmission electron microscopy and microhardness measurement. The maximum hardness(118Hv) was obtained from the specimen aged at 170℃ for 9hrs due to the formation of GP zones and metastable β' phase. In over-aged condition, decrement of hardness showed not so much. This results was attributed to the very slow transformation rate from β' to β phase. It was found that the precipitation sequency was GP zone→metastable hexagonal Mg₂Si(β') →equilibrium fcc Mg₂Si(β).

The purpose of this study was to investigate the postnatal development of pulpal innervation with the tooth development and eruption process in developing rat mandibular molars (postnatal 1, 5, 10, 15, 20, 25, 35day-old and adult rats). Immunohistochemical method was carried out for the detection of nerve fibers, using the antibody against calcitonin gene-related peptide(CGRP). The results were as follows: The feature of CGRP-IR nerve fibers were shown in a bead-like appearance. The time of nerve entering into the dental papilla of tooth follicle began at the occured advanced dentinogenesis. The development of Raschkow plexus began at the formative stage of the roots and was accelerated at the stage of the crown emerged into the oral cavity. The number of nerve fibers entering the odontoblastic layer increased with the tooth eruption and mastication. The development of innervation was shown to be related with the stage of the development of individual teeth rather than the chronological age of the rat.

치내치는 석회화가 되기전에 치관의 함입에 의해서 야기되어지는 치아의 형태이상이다. 영구치뿐만 아니라 유치에서 발생될 수 있지만 주로 상악 측절치에서 발생하며 그 발생빈도는 0.04-10%로 다양하게 보고되고 있다. 치내치는 치수와 치근단 조직으로 교통될 수 있어 이로 인해서 치수의 염증, 치근잔 농양, 낭종 등을 야기하거나 내흡수를 일으킬 수도 있으며 치관의 형태이상을 보이는 등 심미적인 문제도 초래할 수 있다. 치내치는 그 함입의 정도에 따라서 Oehlers씨에 의해서 3가지 형태로 구분된다. 치내치의 다양한 형태중 Type 3의 치내치는 치내치 함입부가 치수와의 교통없이 치근단공이나 측방치주조직으로 opening을 형성하는 형태로 치수감염의 여부에 따라 치료전략이 달라지며, 치수감염에 의한 병소가 존재하는 경우에는 함입된 형태와 복잡성을 고려하여 통상적인 근관치료, 외관적 치근단 절제술, 의도적 재식술 및 발치를 시행할 수 있다. 본 증례에서는 근첨이 개방된 측방 치주공을 가진 치내치로 해당치아가 생활력을 보이고 invagination의 형태가 단순하였기에 invagination에 한정된 근관치료와 근첨형성술을 통하여 성공적인 결과를 보였으며 다을과 같은 결과를 얻었다. 1. Type 3 치내치의 경우에서 치아의 생활력이 유지되고 invagination의 형태가 복잡하지 않다면, 그리고 치수와 invagination과의 교통의 증거가 없다면 invagination에 한정된 근관치료로서 병소의 해결과 해당치아의 생활력 유지가 가능했다. 2. 개방된 근첨을 가진 invagination을 보이는 치내치의 경우 근첨형성술로 개방된 근첨의 폐쇄를 유도할 수 있었고 이런 점을 이용 외과적 술식을 피할 수 있었다. Dens invaginatus is a developmental anomaly resulting from and invagination of the enamel organ. The incidence is highest with maxillary permanent lateral incisors. The reported occurrence ranges from 0.04 to 10%. This anomaly may involve the pulp and periapical tissues and cause pulpal inflammation, loss of vitality, apical and lateral periodontitis, periapical abscesses and cysts and stimulate internal resorption. Oehlers describes dens invaginatus as occurrence in three forms. In treating type 3 invaginatus, treatment strategy can be determined by considering the complexity and accessibility of invagination. In this case, showing simple invagination, it could be treated by simple endodontic treament confining to invagination without loss of vitality of tooth. After treatment of the present case, the results were as follows: 1. In type 3 dens invaginatus, if the tooth is vital and there is no evidence of communication between invagination and pulp, we can save the vitality of the tooth and resolve the lesion by endodontic treament confining to the invagnation. 2. In the invagination with opened apex, the closure of apex can be induced by apexification procedure doing this, we can avoid the neccessity of surgical invagination.

This study was conducted to research into the gymnastic circumstances according to medieval thought and its classified classes. The results of medieval physical education and their contributions to us on the basis of characteristics of their classes and their physical activity are as follows: 1. The gymnastics development of the Middle Ages was hindered by Christian view on physical culture. 2. The aristocratic view on gymnastics was changed into equalitarian by the birth of Christianity. 3. The physical education of Knight was actual military training in the early age and a formal one in later age, moralism was introduced into physical education through knighthood. 4. The medieval gymnastics activities avoided by knight, chmchemn, and aristocracy were highly popular among guidsmen, bourgeois and the peasantry as a recreation like ball-game and dancing. This was developed into modern gymnastic tendency. 5. The medieval gymnastics which was called dark age of physical education owing to the gymnastics view of Stoic asceticism was advanced through the middle of medieval era to ward the modern form of sportmanship in later age.

열분석 방법에 의한 급냉응고 Al-Li-Cu-Zr 합금의 시효거동연구

김순호,김인배 부산대학교 1994 生産技術硏究所論文集 Vol.47 No.

급냉응고된 Al-3.13 wt% Li-1.66 wt% Cu-0.42 wt% Zr 합금의 시효거동을 시차주사열량계 (DSC)에 의한 열분석 방법으로 조사하였다. DSC에 의한 비열측정결과 δ'상과 T₁+δ+ 복합 석출상의 석출에 의한 2개의 발열반응과 이들 상의 재고용에 대응되는 2개의 흡열반응이 각각 확인되었고, 시효온도의 상승과 시효시간의 증가에 따라 δ'상 및 T₁+δ+ 복합석출상의 석출에 대응되는 발열반응의 열량이 감소되었다. DSC 곡선에 나타난 발열과 흡열곡선을 해석하여 얻은 δ'상의 석출과 재고용의 활성화 에너지 값은 각각 98 KJ/mol과 123KJ/mol로서 Al-Li, Al-Li-Mg에 비해서 높은 값을 나타내었다. 시효에 의한 강화가 일어나 DSC에 의한 비열변화 조사결과 나타난 δ'상 석출완료 조건인 210℃, 1시간에서 최고경도값 (Hv 148)을 나타내었다. Effects of aging treatment on the microstructural evolution of a rapidly solidified Al-3.13wt%Li-1.66wt% Cu-0.42wt% Zr alloy were investigated by differential scanning calorimetry (DSC). DSC analysis showed the two exothermic and two endothermic peaks. The two exothermic and endothermic peaks corresponded to δ'and T₁+δ+ composite precipitates precipitation and dissolution reactions respectively. The enthalpies of δ'and T₁+δ+ composite precipitates were decreased with increasing aging temperature and time until the finishing point of precipitation. The activation energy for precipitation and dissolution of δ'was measured as 98 KJ/mol and 123 KJ/mol respectively. These values are higher than those of Al-Li, Al-Li-Cu and Al-Li-Mg alloys. Peak hardness value (Hv 148) was obtained at 210℃ for lhr aging treatment which coincided with finishing point of δ' precipitation.

김지혜,이영은,안상헌,최연희,남순현,송근배 大韓小兒齒科學會 2009 大韓小兒齒科學會誌 Vol.36 No.4

본 연구에서는 장기적인 자일리톨의 섭취가 Streptococcus mutans의 대표적인 독성인자 중 하나인 글루칸 생성에 미치는 영향을 알아보기 위하여 글루칸 합성효소인 glucosyltansferase의 mRNA 발현을 실시간 역전사 중합효소 연쇄반응을 통해 평가하여 다음과 같은 결과를 얻었다. 1. 24개월 동안 자일리톨껌을 섭취한 군에서 타액 내 Streptococcus mutans의 colony 수는 통계적으로 유의하게 감소하였다(p<0.05). 2. 비수용성 글루칸 합성에 관여하는 유전자인 gtfB, gtfC의 발현은 자일리톨껌을 섭취한 군에서 시간이 지남에 따라 유의 하게 감소하였다(p<0.05). 특히 gtfB의 발현은 12개월과 24개월째 대조군에 비하여 통계적으로 유의하게 낮았고, gtfC의 발현은 24개월째 대조군에 비하여 통계적으로 유의하게 낮았다(p<0.05). 3. 수용성 글루칸 합성에 관여하는 유전자인 gtfD의 발현 역시 자일리톨껌을 섭취한 군에서 시간이 지남에 따라 유의하게 감소하였다(p<0.05). 또한 gtfD의 발현은 12개월과 24개월째 대조군에 비하여 통계적으로 유의하게 낮았다(p<0.05). 이상의 결과들을 종합해 보았을 때, 자일리톨의 섭취는 구강 내 Streptococcus mutans의 글루칸 합성 관련 유전자들의 발현을 억제시킴으로써 Streptococcus mutans의 수적인 감소를 가져오는 것으로 생각된다. Xylitol has the ability to reduce the adherence of Streptococcus mutans(S. mutans), which can make it easier to remove plaque, decrease acid production and inhibit dental caries. There are few reports on the effects of xylitol on the expression of the virulence related genes in S. mutans. This study examined the inhibitory effect of chewing gum containing xylitol on glucan synthesis related gene expression of S. mutans. Participants were voluntarily recruited for a women's oral health prevention program, classified into two groups(a control and a xylitol group), and then followed for 2 years. Twenty salivary samples were randomly selected from each group. Colony count and real-time reverse transcription polymerase chain reaction were used to analyze the characteristics of S. mutans. The following results were obtained: The S. mutans counts decreased steadily in the xylitol group over the study period(p<0.05). The expression of the virulence related genes (gtfB, gtfC and gtfD) was significantly lower in the xylitol group than in the control groups (p<0.05). In conclusion, these results suggest that chewing xylitol gum for a long period of time may reduce the expression of the genes associated with S. mutans virulence, which can result in a decrease growth of S. mutans colonies as a result.

The purpose of this study was to investigate the distribution of CGRP immunoreactive nerve fibers in rat squamosomandibular joint with postnatal development. Squamosomandibular joint with adjacent tissue of 8 groups of rats(1,5,10,15,20,25,35-postnatal day and adult groups) were removed en bloc and processed for immunohistochemistry and were subjected to light microscopic examination. The results obtained were as follows; 1. The anterior portion of the articular disk was most densely innervated, followed by the posterior, lateral, and medial portions in each group. 2. Increase of CGRP immunoreactive nerve fibers was evident in 10,15,20 postnatal day groups. 3. Almost no CGRP immunoreactive nerve fibers were observed in articular surface of disk proper, mandibular fossa and condyle head of each group. These result suggest that CGRP immunoreactive nerve fibers increased in synovial membrane and peripheral portion of articular disk during 10-20 postnatal day may play a important role in squamosomandibular joint function after weaning period.
