장항익,황현식 대한치과교정학회 1995 대한치과교정학회지 Vol.25 No.2

교정치료시 보다 효과적인 치아 이동을 위한 한 방법으로 최근 자석 사용이 고려되고 있다. 영구자석의 체적 변화가 자력에 미치는 영향을 파악하고자 한 쪽에 한 개의 자석을 고정하고 반대쪽 자석의 두께나 넓이를 일정한 비율로 증가시키면서 양측 간에 나타나는 자력을 비교 연구한 결과 다음과 같은 결과를 얻었다. 1. 두께를 증가시킨 경우에는 자력이 증가하였으나 넓이를 증가시킨 경우 자력이 오히려 감소하였다. 2. 체적 증가에 따른 자력의 증간은 대수함수 분포 양상을 나타내었다. 3. 두께 증가로 체적을 변화시킨 경우, 같은 두께라도 처음부터 크게 제작한 자석이 작은 자석을 여러 개 합한 것보다 큰 자력을 보였다. 본 연구 결과 구강내에서 자력을 증가시키기 위해서는, 마주보는 자석면은 같게 유지하면서 넓이 증가보다는 두께를 증가시키는 방법이, 그리고 처음부터 두꺼운 자석을 사용하는 것이 보다 효율적임을 알 수 있었다. Recently, magnetic forces are considered as a method for more efficient tooth movement. The purpose of this study was to evaluate the effects of the changes of the magnetic volume on the magnetic forces. The universal testing machine and the electronic balance were used for the exact measurement of the force with constant air gap. While the magnet was kept same on one side, the magnetic volume of the other side was increased gradually in four manners. In the first group, the thickness was increased by adding same size of the magnets on after another while the thickness was increased by changing with a thicker magnet gradually in the second group. In the third group, the width was increased by adding same size of the magnets while the width was increased by changing with a wider magnet gradually in the last group. The results were as follows : 1. With the increase of the thickness, the magnetic force increased, while the magnetic force decreased with the increase of the width. 2. The magnetic force according to the change of the magnetic volume showed the distribution of the logarithmic function. 3. An originally thick magnet showed larger force than the added magnets although both of them had same volume.

Polycyclic aromatic hydrocarbons(PAHs) in sediments of Kwangyang bay on Korea, have been investigated by gas chromatography-mass spectrometery (GC/MS). The average content of total PAHs in all samples was 2,211ppb, and the range was from 36 to 22,699pph. The higher concentrations were found in sediment sampled near Kwangyang iron processing plant, Taeindo. The resulting distributions of PAHs according to the number of aromatic ring and molecular ratios of specific aromatic compounds (phenanthrene, anthracene, fluoranthene and pyrene) have been discussed in terms of sample location, origin of the organic matter. Four, five and six rings of PAHs were mainly found near to Kwangyang iron processing plant, and three and four rings near to Yeosu chemical kombinat. This result typically indicated the local characteristics, depending on the origin of PAHs.

Physicochemical characteristics of Kwangyang Bay, have been investigated on the effects of inputting rivers just after rainy season in summer 2003. The results ranged from 4.96~8.01 mg/L for DO, 1.16~3.09 mg/L for COD, 7.21~67.71 μM for DIN and 0.12~121.84 μM for phosphate. The COD of Yeosu Area was 1.19~3.09 mg/L, Kwangyang Area was 1.23 ~ 2.76 mg/L. The COD of Wallae cheon in Yeosu Area was 3.09 mg/L and Donghoan in Kwangyang Area was 2.76 mg/L. The reason of high COD might be industrial sewage of organic chemical plants and iron foundry. DIN of Yeosu Area and Kwangyang Area were 7.21--63.43 μM and 8.43 67.71 μM respectively. The average phosphate of Yeosu Area was 23.65 μM. The source of phosphate might be industrial sewages of fertilizer plant and phosphate gypsum stocked with high amounts. The metal concentrations were measured in the range of 1.01~175.10 ㎍/L for Cu, 0.13~1.78 ㎍/L for Cd, 1.13~5.21 ㎍/L for Pb, 1.58~13.57 ㎍/L for Cr and 1.07~20.68 ㎍/L for As. The average Cu concentration was 78.99 ㎍/L in Kwangyang Area. The source of Cu might be industrial sewage of iron foundry. The average Cr concentration of Yeosu Area was 9.07 ㎍/L. That is 2 times higher than Kwangyang Bay 5.74 gg/L, because of sewage of chemical plants.

This experiment was carried out to know the effect of agricultural ehemicals as a fruit thinner of apple varieties such as Fuji, yellow delicious, Jonagold and starkrimson with sevin and smithion in 1990. The results were as follows. 1) Fuji cultivar showed higher thinning effect with sevin and smithion in the center fruit. Trees treated with smithion was 89.3% in the side fruit and 67.5% in thinning rate with sevin 2) Simmilar thinning effect were shown in yellow delicious and starkrimson cultivars, too. 3) Jonagold cultivar showed striking thinning effect and that side fruits were dropped cntirely. This cultivar seemed to response well. From these results, agricultural chemicals, sevin and smithion can be applied as a thinning agent for apple cultivars effectively without any injury to the tree, the authors believed.

In this study, positive versus negative symptoms of schizophrenia were examined in relation to social networks. The subjects consisted of 36 positive symptom(PS) and 35 negative symptom(NS) groups of schizophrenics admitted to the Anyang Neuropsychiatric Hospital. There was no significant difference in sociodemographic data(ie. sex, age, education etc) between the two groups. Structurally, the social network of NS group was smaller and contained lesser number of friends and family members than PS group. Furthermore, with respect to the functional aspect of social network. 1) The frequency of contact, comfortability, and material support given by the patients were much less in NS group. However, there was no difference in emotional, material, and informative support between the two groups. 2) In contrast with the PS group, in the 'most important person' category of social network in the NS group, the proportion of 'other people' (fellow patients, hospital staff etc) was much higher than that of friends and family members. 3) All negative symptoms correlated negatively with the size of social network. However, no such relationship existed among PS group. These results indicated close relationships existing between different types of schizophrenic symptoms and the structural and functional aspect of social network.

양앵두 佐藤錦 및 Napoleon品種을 供試하여 Ca(OH)_2 處理濃度 및 處理回數에 따른 果實生長, 果實品質, 칼슘축적 및 裂果에 미치는 影響을 調査하였던바 다음과 같은 結果를 얻었다. 1. 양앵두 果實生長은 佐藤錦품종에서 收穫1週前 Ca(OH)_2 처리농도간에는 차이가 없었으나, Napoleon품종에서 Ca(OH)_2 처리회수가 증가 할수록 抑制되었다. 2. 可溶性 固形物과 Anthocyanin함량은 Ca(OH)_2 처리농도 및 처리회수를 증가 할수록 감소하였으나, 유기산 함량은 증가하였다. 3. 果實內 칼슘축적은 Ca(OH)_2 처리농도 및 처리회수가 증가 할수록 증가하였고, 佐藤錦 품종에서 과실내 칼슘함량은 과피, 종자, 과육, 핵의 순이였고, Napoleon품종에서는 종자, 과피, 과육, 핵의 순이였다. 4. 裂果방지를 위한 Ca(OH)_2 처리는 7.2g/l를 수확 3주전부터 1週間隔으로 3회 살포하는 것이 열과를 감소시키는데 효과적이였다. The study was conducted to investigate the influences of several concentrations of Ca(OH)_2 and application time on fruit growth, quality, contents of Ca in fruits and cracking of 'sa Tou Nisiki' and 'Napoleon' sweet cherry. The results obtained are summarized as follows; 1. In Ca(OH)_2 treatments, the fruit growth of 'Sa Tou Nisiki' and 'Napoleon' sweet cherry was not influenced by its concentrations but by application times of Ca(OH)_2. 2. Contents of soluble solids and anthocyanin according to concentreation and application of Ca(OH)_2 were decreased, while titratable acidity was increased respectively. 3. Contents of Ca in the fruit according to concentration and application of Ca(OH)_2 were increased and Ca contents in both fruits differ from fruit portions. 4. Preharvest application of Ca(OH)_2 by 0.72% and three times applications reduced cracking of 'Sa Tou Nisiki' and 'Napoleon' sweet cherry. From these results, twice applications of Ca(OH)_2 to the sweet cherry are recommended for the best fruit quality, the authors believed.
