문상진,최영철 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.1

손가락 빨기는 유아의 심리적인 욕구와 영양적인 욕구에서 유발되어 흔히 2~3세까지는 정상적으로 간주된다. 이 시기까지의 상, 하악골과 교합을 포함하는 치열궁에의 영향은 습관의 중단과 함께 자연적으로 개선되는 경향을 보이는 것으로 알려져 있다. 3.5~4세 이후까지 손가락 빨기가 지속된 경우, 이로 인해 유발된 부정교합의 정도가 심하고 상, 하악골 발달의 부조화가 현저하며 자연적인 개선을 예측하기 어려울 때에는 적극적인 치료를 시행하는 것이 바람직하다. 습관의 중단 및 습관으로 인한 부정교합과 심한 골격적 부조화를 해소하기 위해 Fra¨nkel appliance는 매우 효과적인 장치이다. 본 증례는 경희대학교 치과병원 소아치과에 내원한 환아 중 손가락 빨기로 인한 심한 수평피개도와 상, 하악골 발달의 부조화, 심하게 함몰된 안모를 가진 3세 어린이와 정중선 변위, 안면 비대칭, 편측성 구치부 반대 교합을 지닌 4세 어린이에서 습관의 중단과 부정 교합의 치료를 위해 Fra¨nkel appliance를 이용해 치료하였다. 환아들은 Fra¨nkel appliance를 장착한 이후에 습관이 바로 중단되었으며 증례 1 에서는 심한 수평피개도와 상, 하악골의 부조화가 FR-Ⅱ 장착 16개월 후 개선되었다. 증례 2 에서는 정중선의 변위, 하악골의 편위, 편측성 구치부 반대교합, 안모 비대칭 이 FR-Ⅲ 장착 10개월 후 개선되었다. Fra¨nkel appliance는 골격적 부조화의 개선 및 Habit breaker로서 추천할 만한 장치이다. The habit of finger sucking is a reflex occurring in the oral stage, due to nutritive and psychological desire. The habit of finger sucking is considered to be normal till 3 years of age. Dento-skeletal effect on maxillo-mandibular complex including occlusion is naturally correction, when habit stopped before 3 years. If finger sucking continues till 3-4 years, Finger sucking leads to severe malocclusion and remarkable discrepancy maxillo-mandibular complex, which is difficult in expectation of natural correction. It is necessary to positive treatment. Treatment of malocclusion, as related to finger sucking is classified two methods. (psychological approach and orthodontic appliance) To stop a habit and to correct severe skeletal discrepancy and malocclusion, fra¨nkel appliance is very effective device. This study is to report two cases of treatment of malocclusion, as related to finger sucking. 2 years 10 months old girl with severe overjet, maxillo-mandibular skeletal discrepancy and severe convex facial profile was treated with a FR-Ⅱ appliance. Finger sucking habit stopped immediately. After 16 months, severe overjet, maxillo-mandibular skeletal discrepancy and severe convex facial profile was corrected. 4 years 2 months old girl with midline deviation, mandibular right shift, collateral posterior crossbite and facial asymmetry was treated with a FR-Ⅲ appliance. Finger sucking habit stopped immediately. After 10 month, Midline deviation, mandibular right shift, collateral posterior crossbite and facial asymmetry were corrected. FR-appliance is a recommendable appliance for a habit breaker and correction of skeletal discrepancy.

The purpose of this study was to investigate swimming pool usage at sports centers in Samcheok, South Korea and to identify ways of improving its operation. A survey developed by the researcher was used to collect data from a random sample of 243 participants in swimming programs at the sports centers. The internal operation data were also obtained from each sports center to analyze its operation of a swimming pool. 1. Of the 243 participants, 69% indicated that improving physical health was considered the most common reason for which they participated in the swimming program. Seventeen percent reported that utilizing their leisure time was the reason for them to start swimming. Seventeen percent of the respondents were influenced by their friends to begin swimming while 47% decided to begin swimming without other' s influence. 2. Fifty-three percent of male respondents (53%) used a swimming pool early morning and 27% used it later afternoon. On the other hand, 66% of female respondents used it in the morning and 22% used it in the early morning. The majority of the female respondents indicated their duration of using it was two years or more, while the majority of the male reported their duration was three to six months. 3. Most respondents (63%) spent less than 30 minutes to get to their sports center by an automobile. Fifty-three percent drove their car and 40% used a transportation provided by their sports center. 4. More than 78% were satisfied with their swimming instructor. Fifty-one percent were specially satisfied with her/his service and 21% were satisfied with her/his coaching skills. 5. Fifty-four percent were satisfied with its facilities while 2% were dissatisfied with it. 6. The most respondents preferred to purchase a three-month membership. Sixty-four percent were satisfied with their membership fees. 7. Only 2% indicated that they want to discontinue their swimming program. Reasons for that were a lack of time (31%) and unaffordable membership fees (27%). 8. Statistically significant differences were found in the satisfaction with its facilities between married and unmarried respondents. In addition, statistically significant differences were found in the satisfaction with its store and restaurant based on their demographical characteristics. 9. The peak season for swimming pool usage was between June and August while the slower season was between November and February. Based on the analysis of the internal operation data, there had been a loss of $54,000 for 2000 and $80,000 for 2001.

Feasibility of simple rapid methods to determine nitrate concentration in soil and plant sap in siltu was assessed using Merckoquant strip method and Cardy NO_(3)- sensor. The saturated extract of a soil was sampled readily in field by a simple apparatus which consists of a syringe, a vial and a hand vacuum pump with a vacuum valve. The simple measurement methods for saturated extract were tested for soil samples obtained from the thirty three farm vinyl houses around Chuncheon, Kang-weon-Do and Kuri, Kyeonggi-Do. The methods were tested for soil and plant sap samples grown under different fertilization in a vinyl house at Kangweon National University. The main treatments were with or without organic fertilizer, and subtreatments were four nitrogen levels ; 0, 100, 200 and 400kg/ha for lettuce and 0, 150, 300 and 500k9/ha for cucumber. The Cardy sensor method showed a high confidence for soil and plant sap nitrate measurement. The Merckoquant strip method was also reliable, but checking electrical conductivity was recommended for better reliability. The soil nitrate concentration above 10mmo1/L was not desirable for lettuce yield, and 15mmo1/L for cucumber. The respective electrical conductivities of saturated extracts were 3 to 4ds/m at these concentrations. The soil nitrate concentration could be monitored by Amberlite IRN-150 Resin-bag. A good correlation was obtained between the soil nitrate concentration and the nitrate absorbed by the resin bag. Therefore, use of the resin bag could be recommended to monitor nitrate in soil, minimizing soil destruction.

Choi, Yeong Hwan,Moon, Ja Young,Seo, Byoung Joo,Kim, Won Kyung,Cho, Jeong Sang,Choi, Min Su,Lim, Jae Sam,Kim, Sung Bok,Kim, Won Il,Hur, Jin The Korean Society of Veterinary Service 2017 韓國家畜衛生學會誌 Vol.40 No.4

Enterotoxigenic Escherichia coli (ETEC) strains producing each F4, F5, F6 and F41 fimbriae were lysed by GI24 peptide. The lysate cells were used as ETEC vaccine candidate. This study was carried out to examine whether intramuscular (im) immunization of pregnant sows with the novel vaccine candidate could effectively protect their neonatal piglets against ETEC colibacillosis. All pregnant sows were primed at 11 weeks and were boosted at 14 weeks of pregnancy. Group A sows were im inoculated with PBS. Group B sows were im immunized with $2{\times}10^9$ the mixture. Seral IgG, colostral IgA and IgG titers from group B sows, and seral IgG and IgA levels in group B piglets were significantly higher than those of group A sows and piglets, respectively. After challenge with wild-type ETEC, diarrhea and mortality was not observed in group B piglets. However, diarrhea was observed in 66.7% of group A piglets, and 33.3% mortality was observed. These findings indicate that im immunization of sows with the mixture of the novel vaccine candidate can effectively protect their offspring from ETEC colibacillosis.
