Since 1950s, fine needle aspiration(FNA) cytology has become increasingly popular and numerous reports have demonstrate its accuracy, safety and cost-effectiveness. To evaluate the role of diagnostic FNA cytology in the thyroid nodule, authors compared preoperative cytologic findings with postoperative histologic diagnosis in two hundred two thyroid nodules underwent surgical resection at Department of Surgery, Pusan Paik Hospital. from July 1990 to December 1993. FNA and thyroidectomy was performed primarily by one Head and Neck surgeon and specimen was interpreted by several pathologists. One hundred seventy two FNAs(85%) were interpreted as positive for benign lesion or carcinoma and thirty(15%, cystic in 25, non-cystic lesion in 5 cases) were unsatisfactory specimens for interpretation. The preoperative cytologic diagnosis of 172 cases revealed 'benign' in 112. 'suspicious cancer' in 10 and 'cancer' in 50 cases. Postoperative pathologic diagnosis showed 'nodular goiter' in 64. 'benign tumor' in 43, 'thyroiditis' in 4 and 'cancer' in 61 cases. The value of preoperative FNA diagnosis for thyroid cancer yielded a sensitivity of 85.2%, a specificity of 92.7%, false negative rate 5.2%, false positive rate 4.5% and positive predictive value and overall accuracy were 86.6% and 90.1% respectively. Preoperative rate of malignancy could be increased up to 35.5% by using FNA.

The purpose of this study was to compare the diagnostic performance of Waters' and panoramic view; maxillary sinus posteroanterior and lateral scanography of Scanora/sup (R)/ for mucosal thickening of maxillary sinus as well as to identify the utility of Scanora/sup (R)/ for the detection of maxillary sinus disease. The assessment was done at 66 maxillary sinuses in 45 patients and the results were as follows ; 1. Estimation of presence or absence of mucosal thickening. The sensitivity, specificity, and positive and negative predictive value of maxillary sinus posteroanterior and lateral scanography were 0.865, 0.860, 0.921, and 0.805 respectively and slightly higher than those of Waters' and panoramic views, which were 0.832, 0.835, 0.903, and 0.728 respectively. However, paired t-test showed no significant differences in the diagnostic performance of the two pairs of imaging modalities. 2. Estimation of the types of mucosal thickening. The diagnostic accuracy for type I, II, III was 75.3％ on Waters' and panoramic view; 77.9％ on maxillary sinus posteroanterior and lateral scanography. It was higher on the latter ,but showed no significant differences from that on the former. 3. Reliability of interpretation. In itraobserver and interobserver agreement, both overall rates of agreement and kappa-value were slightly higher on maxillary sinus posteroanterior and lateral scanography than on Waters' and panoramic views. There was no significant differences between the two pairs of imaging modalities. These results suggested that scanogram is a useful diagnostic radiography as well as Waters' and panoramic views for detection of maxillary sinusitis.

Today's young generation in digital era has a rich education environment and convenient life, on the other hand, there was negative impact on growth as normal body type because of adverse impact on an excessive study and insufficient exercise, etc. Also, for these people in IT culture generation, using small mobile including computer for long time is becoming main issue as changing factor in posture and body type in terms of spine like their neck disc. This body-typed characteristic reaches to normal adult body type in the process of physical development of adult woman and has least modification in body type. Therefore, despite of early young generation, body suitability of upper body clothes might caused imbalance. So, for intended to early 20s women, to design clothes with consideration on imbalance of body type by bended and curved spine, body type studies about size of upper body and forms are needed. As this researcher measured the body type of early 20s college women in metropolitan area, changes in body type of young generation with use of digital equipment recently were recognized since straight body type was decreased unequally and had characteristic in terms of changes to be bended body type. The changes of these body type should be considered to make clothes. Also, since there are some restrictions on this research objects in terms of local and numbers of measured objects, a broad interpretation of result on this research should be really careful.

The aim of this study was to evaluate the diagnostic value of fine needle aspiration cytology (FNAC) for the assessment of palpable enlarged lymph nodes. The authors reviewed the results of 1,346 FNACs of palpable enlarged lymph nodes performed at Pusan National University Hospital from 1998 to 2004. Of the 1,346 cases, 1,265 (94.0%) were satisfactory and 81 (6.0%) unsatisfactory. Cytologic diagnoses were judged in 488 cases, based on subsequent histologic diagnoses, clinical follow up, or both. Global results for all malignancies (lymphoid and non-lymphoid neoplasms) based on cases with final diagnoses, showed a sensitivity of 87.4% and a specificity of 98.7%. The overall diagnostic accuracy was 93,2%, and the false negative rate reduced from 12,6% to 7,3% when lymphomatous cases were excluded. The annual data for this period showed that the number of diagnostic lymph node biopsies and the rate of inadequately sampled material markedly decreased. Gene rearrangement studies for IgH and TCR ${\gamma}$ were helful in 30 cases. FNAC is a useful initial diagnostic procedure for the evaluation of palpable enlarged lymph nodes. However, the technique should be assisted by the appropriate ancillary studies and by proper interpretation by a cytopathologist.

Objectives The purpose of this study was to find out whether if there is correlation between the pattern differentiation questionnaire and edema index of body composition analysis. Methods The authors obtained results of pattern differentiation Questionnaires and body composition analysis tests from 195 female patients who visited the Oriental gynecology department in Kyung Hee university Oriental medicine hospital at Gang-dong. The authors conducted correlation analysis between indicators of Body composition analysis and each part of the pattern differentiation Questionnaire. Pearson correlation analysis was performed on SPSS version 13.0 for windows. Results There was negative correlation between the Phlegm Questionnaire and right arm ECF, left arm ECF, and left arm ECW of the Body composition index. There was no correlation between Yin-deficiency Questionnaire and Body composition index. There was no correlation between Heat pattern Questionnaire and Body composition index. There was positive correlation between the Cold pattern Questionnaire and right leg ECF, and right leg ECW of the body composition index. There was no correlation between degree of edema self-awareness and Body composition index. Conclusions The result showed that each Questionnaire score has different correlation or even no correlation with Body composition index and degree of edema self-awareness. Further studies are needed for a better understanding and interpretation of the relationship between edema index on Body composition analysis and Questionnaires.

This study was applied to the PCA (Primary Components Analysis) for the sixteen table setting at the 2017 Yeongju local food contest. In this contest, we have developed a seonbibansang and a temple one-dish meal. As a result of the correlation analysis, the applicability and composition were 0.7980, harmony and taste were 0.7747 and easiness and composition were 0.7435. In the Primary Component $Y_1$, all the variables $X_1{\cdots}X_{10}$ mean that the quality of the food had positive values greater than zero. The second Primary Component $Y_2$ has a large positive value while $X_4$, $X_5$, $X_6$, $X_7$, $X_9$ have negative values. $Y_2$ is a value representing the sanitation variable, and can be considered a traditional and characteristic table setting natural to the native food in Yeongju. In addition, we developed an-hyangbansang and seonmyoaecheong food content by applying PCA factors (the elements of harmony, ease and sanitation). Table setting of an-hyangbansang provided energy 61.5%, protein 20.0% and fat 18.5% and seonmyoaecheong provided energy 62.7%, protein 15.4% and fat 22.2%. This satisfied the necessary amount of caloric nutrient intake that could be provided in a meal. Especially through story-telling, a modern interpretation - or rebranding - of local and traditional foods could make these traditional food products familiar to consumers currently. The developed table setting is felt to be conductive to the possible commercialization and introduction of traditional food into the mainstream commercial food service industry.

Charlotte $Bront{\ddot{e}}^{\prime}s$ novel Jane Eyre has long been doted on as one of the canonized texts of British literature since its publication. Seemingly, this romantic novel has nothing to do with plantation based on slave trade. However, paying a keen attention to the fact that Jane's enormous inheritance results from wine plantation at a colony, this essay re-interprets Bertha's drinking and madness as evidence of imperialism. For the porter/jin Bertha and Grace Poole enjoy might have some suspicious connection with wine, the very root of Jane's great expectations. Jean Ryes' Wide Sargasso Sea, writing Jane Eyre back, records Bertha as "a white resident of the West Indies, a colonizer of European descent" (326). However, Jane Eyre, in my interpretation, describes Bertha pretty much as a black Creole. At any rate, the view that the white West Indians are tainted by miscegenation proves contemporary racism and is reflected in the text through Bertha and her mother's intemperate drinking and madness. Drinking and madness are stigmatized as the evidence of the so-called "bad blood"; embodying the stereotypes of drinking, madness, and sexual corruption, Creoles, the very inescapable product of imperialism, provide a convenient excuse for justifying imperialism for purity, civilization, and moral cleanness. In this way, Jane Eyre needs to be re-interpreted politically and historically in the context of colonialism. British imperialism pursues a tremendous amount of profits through grape plantation and wine trades; however, it cleverly leaves in the colony the associated images such as intemperate drinking and madness. Bertha, transferred from Jamaica to Britain, takes in these negative images of "savageness." Transcending the narrow confines of feminist criticism obsessed with doubling between Bertha and Jane, this essay, accordingly, reads Bertha the prisoner in the attic as the captive for perpetuating imperialism. This reading hinges upon interpreting Rochester and St John as colonizers bearing the so-called "white men's burden" to cultivate and civilize savages much like crops such as grapes and sugarcane in the colonial plantation.

진단방사선 영상을 획득하기 위해 이용되는 X-ray는 연속적인 에너지 분포를 가지지만 저에너지 광자의 경우에는 영상 형성 보다는 환자피폭에 더 많은 기여를 하는 것으로 알려져 있다. 이러한 저에너지 광자를 제거하기 위해 임상에서는 알루미늄 필터를 적용하고 있으나 이는 빔 경화 현상으로 인한 영상 품질에 악영향을 미칠 가능성이 있다. 이에 본 연구에서는 알루미늄 필터에 의한 산란 선량이 의료 영상의 품질에 미치는 영향에 대하여 고찰하고자 하였다. 또한, 영상의 대조도 저하를 정량적으로 표현하기 위해 상대 표준 편차 및 산란 열화 인자를 평가 지표로서 활용하였다. 연구 결과, 70 kVp 이상의 전압에서 진단 영상을 확보 시 NCRP에 의해 권장되는 2.5 mmAl를 기준에서 전방산란율 분석 결과 0.69 %, 산란 열화 인자 분석 결과는 0.005, NNPS 분석 결과 3.59 mm2의 변화가 나타났다. 이러한 연구 결과를 바탕으로 알루미늄 필터의 두께가 증가함에 따라 발생하는 산란 선량이 의료 영상의 품질을 저하시키는 것을 정량적으로 검증하였다.

Purpose: This study aimed to examine effect sizes of leadership styles of nursing managers on turnover intention of hospital nurses. Methods: A systematic review and meta-analysis were conducted in accordance with the PRISMA and MOOSE guidelines. Participants were nurses working in hospitals. The intervention involved nursing managers' leadership styles; the outcome assessed was nurses' turnover intention. This was an observational study design. Eleven databases were searched to obtain articles published in Korean or English. Of the 14,428 articles reviewed, 21 were included in systematic review and meta-analysis. Comprehensive Meta-Analysis and R software programs were used. Results: The total effect size r (ESr) was - 0.25 (95% confidence interval: - 0.29 to - 0.20). Effect sizes of each leadership style on turnover intention were as follows: ethical leadership (ESr = - 0.34), transformational leadership (ESr = - 0.28), authentic leadership (ESr = - 0.23), transactional leadership (ESr = - 0.21), and passive avoidant leadership (ESr = 0.13). Ethical leadership was the most effective style in decreasing turnover intention of hospital nurses. Conclusion: Positive leadership styles of nurse managers effectively decrease turnover intention of hospital nurses, and negative leadership styles of nurse managers effectively increase turnover intention of hospital nurses. The ethical leadership style is the most effective in decreasing turnover intention of hospital nurses; however, it requires careful interpretation as its effects are reported by only two studies. This study contributes to addressing the high turnover rate of hospital nurses and developing positive leadership styles of nurse managers in hospital settings.
