Maternal stress was very common symptom that every pregnant women could have experienced during pregnant period. We found that the causative factors of stress for subjects were physical change(50.8%), family relationship(13.6%), change of body image(7.4%), concern baby(6.8%), economic difficulties(6.4%), depress(4.3%), morning sickness(3%), and miscellaneous(3.5%). According to our study, maternal stress during the first trimester negatively correlated with food and nutrients intake of pregnant women and gave low weight gain during pregnancy and low birth weight of infants. It also significantly correlated with monthly income(p<0.001) and monthly food cost(p<0.001) during pregnant period. Mean intake of Calcium and Iron were $47{\sim}60%$ of RDA and $35{\sim}48$ of RDA, respectively. With the Iron supplement the total intake of Iron exceeded 100% of RDA. We also found majority of food items, except seaweeds, fruits and vegetables, were negatively correlated with maternal stress during three trimesters. Additional support system projected by professionals in health-care field could mediate maternal stress and lead to healthy pregnancy outcome.

본 연구는 치열궁 길이 부조화(Arch length discrepancy : 이하 ALD)의 원인요소간의 상대적 중요성과 혼합치열기에서의 예측가능성을 알아보고자 시행되었다. Angle씨 I급 대구치관계이며 근기능 이상이나 골격형태의 이상이 없다고 판단되는 142명의 진단모형을 이용하여 성별과 ALD의 양에 따라 여섯군으로 나누어 각 치아의 크기와 치열궁 각 부위의 크기를 계측하였다. SPSS통계처리 프로그램을 이용하여 각군의 평균, 표준편차를 구하고 Student t-test, 상관관계 분석, 요인분석, 다중회귀분석을 실시하였으며 혼합치열기에서 얻을 수 있는 자료들을 이용한 ALD의 예측가능성을 평가하여 다음과 같은 결과를 얻었다. 1. 성별에 따른 차이는 정상군에서는 거의 보이지 않았으며 spacing군은 대부분의 계측치에서, crowding군은 몇가지 치열궁의 크기에 관한 계측치에서 유의한 차이를 보였다. 2. 남자crowding군과 여자 spacing군은 해당 정상군에 비해 주로 치아크기에 관한 계측치에서 유의한 차이를 보였다. 3. 남자 spacing군과 여자crowding군은 해당 정상군에 비해 치열궁의 크기에 관한 계측치에서 유의한 차이를 보였다. 4. 상관관계분석과 요인분석결과에서는 주로 치열궁의 크기에 관한 계측치들이 ALD와 큰 연관성을 나타내었다. 5. 혼합치열기에서 얻을 수 있는 정보인 중절치, 측절치, 제1대구치의 폭경과 제1대구치간 폭경, 치열궁 장경 을 이용한 ALD의 다중회귀분석은 최소 $63\%$에서 최대 $80\%$의 예측도(R square)를 보였다.

A malformation of the anal fin in longfin trevally, Carangoides armatus, is described and compared with normal specimens. The fish specimen is clearly shown anal fin deformity with missing of 3 spines and 6 rays. The remaining eleven anal fin rays are shorter than those in the normal specimen. The causative factors of this anomaly were discussed.

A Study on Scoliosis Milwaukee Brace , Therapeutic Exercise -Oh, Kuyung- Hwan Scoliosis implies an appreciable lateral deviation in the spine. There are numerous theories of the etiology of scolisosis. but the true causative factors remain unknown ;thus this affliction currently cannot be prevented. Treatment essentially consists of early recognition, correction of existing curves, and prevention of the further progression of the curves . Tremendous strides are being made in the treatment of severe scoliosis but the desire for early nonoperative treatment is of paramount important. Many conservative nonoperative procedures have been advocated. Among th-em .Milwaukee brace and therapeutic exercise are the most effective ones .

Ginsan, a polysaccharide extracted from Panax ginseng. was earlier scrutinized for a biological-response modifier. We further studied the protective and restorative activity of Ginsan against sublethal dose irradiation owing to increase production of endogenous hematopoietic growth factors such as IL-1. TNF-${\alpha}$. IL-6, GM-CSF. Which induce strong redox-emzyme elevation. Exposing to radiation induces reactive oxygen species (ROS). which play an important causative role in radiation damage.

The purposes of this study were to identify the prevalence of fatigue. and factors influencing fatigue in women with rheumatoid arthritis. The subjects were 124 patients with rheumatoid arthritis. Most of all patients felt fatigue and mean score measured by Multidimensional Assessment of Fatigue was relatirely high. Fatigue was positively correlated with pain intensity, the number of pain sites, functional disability, depression. and sleep quality. A hierachical regression model was used to determine the variance which accounts for fatigue. Pain intensity, depression. sleep quality accounted for fatigue significantly. This finding indicates that pain influences fatigue through depression and sleep quality ; depression through sleep quality. The causative factors could be identified by further study of structural eqation model.

Purpose: To identify the frequency of bacterial isolates in early-onset neonatal sepsis (EONS) and their antimicrobial resistance pattern. Methods: A retrospective study of EONS was conducted at the Beni Suef University Hospital from September 2008 to September 2012. A case of EONS was defined as an infant who had clinical signs of infection or who was born to a mother with risk factors for infection, and in whom blood culture obtained within 72 hours of life grew a bacterial pathogen. Results: Of 673 neonates screened, there were 138 positive blood cultures (20.5%) (confirmed EONS). Of the recovered isolates, 86.2% were gram-negative pathogens. Klebsiella pneumoniae (42.8%), Enterobacter cloacae (22.5%), and Escherichia coli (13.8%) were the commonest isolated organisms. The most common gram-positive microorganism was Staphylococcus aureus accounting for only 12 isolates (8.7%). All Klebsiella isolates and 93% of Enterobacter isolates were resistant to ampicillin. Gram-negative pathogens had the maximum overall sensitivity to imipenem, cefepime, and ciprofloxacin; whereas, gram-positive isolates were most susceptible to vancomycin, imipenem, and piperacillin. Conclusion: K. pneumoniae was the predominant causative bacteria of EONS followed by E. cloacae and E. coli. There was a high resistance to ampicillin. Imipenem had the maximum overall activity against the causative bacteria. Continuous surveillance is needed to monitor the changing epidemiology of pathogens and antibiotic sensitivity.

This research investigates how using algae as an ecotoxicological test species is easier than using daphnia for identifying toxic causative substances. From the results of the ecotoxicity measurements on the Shihwa lake and its tributaries, heavy metals were considered as one of major factors in causing toxicity. The algae ecotoxicity value was 9.6 while the daphnia ecotoxicity value was 0.8 in the Jeongwang stream. By using algae as the test species, we could identify the toxicity that causes heavy metals which might otherwise have been missed with only daphnia. The results from the EDTA addition test showed that zinc and copper were the main toxic causative substances in the Jeongwang stream and Gunja stream.

Purpose: The goal of this study was to investigate the causative factors related to the stress of temporomandibular disorders (TMDs) by evaluating salivary cortisol concentration in young adult TMD patients and control groups. Methods: Saliva was obtained from 32 young adult TMDs patients and 34 control patients without a history of TMDs who visited Chosun University Dental Hospital between June 1 and August 31, 2021. Enzyme-linked immunosorbent assay was conducted to measure the salivary cortisol concentration. Results: The salivary cortisol concentration in the TMD patient group and the control group differed significant significantly (p<0.05). The salivary cortisol concentration according to the duration of the clinical symptom of TMD differed significantly difference between the two groups in the male. The salivary cortisol concentration according to perceived stress level differed significantly in the mild and moderate groups (p<0.05). There was no significant difference in salivary cortisol concentration between the two groups related to bruxism or clenching (p>0.05). Conclusions: The salivary cortisol concentration in the TMD patient group and the control group showed statistical relevance, indicating that stress was a causative factor.
