The aim of this study was to investigate the quality properties of beef jerky replaced salt (NaCl) with red pepper paste, soy sauce and soybean paste. The quality properties of beef jerky including water activity (aw), pH, moisture content, protein content, color, shear force, texture profile analysis and sensory evaluations were investigated. The sliced beef samples were marinated at salt (control), soybean paste (T1), soy sauce (T2) and red pepper paste (T3) for 24 h and then dried at 70℃ for 8 h. The aw and moisture content varied from 0.88 to 0.79 and from 28.87% to 22.98%, respectively. All treatment samples showed higher final aw and moisture content than the control sample after drying for the 8 h (p<0.05). The protein content of T2 and T3 samples were lower than the control. Also, shear force and hardness value of all treatment samples had lower than the control (p<0.05). However, all treatment samples showed lower saltiness intensity than the control sample. Sensory panelists recorded greater flavor and texture scores to the samples with soy sauce replacement. Therefore, sensory panels found that the T2 samples had better overall acceptability scores than the other beef jerky samples (p<0.05). 본 연구는 소금을 된장, 간장 및 고추장으로 대체한 우육포의 품질특성 구명 및 전통장류를 이용한 우육포의 제조가능성을 타진코자 실시하였다. 본 실험에 이용된 원료육은 한우육의 semimembranosus 근육을 이용하여 동일한 염도(15)의 소금(대조구), 된장, 간장 및 고추장을 염지액의 2% 수준으로 첨가시켜 70℃에서 8시간동안 건조하였다. 수분활성도는 0.79-0.88의 범위를 만족하며, 처리구에서 대조구인 소금 첨가구에 비해 높은 수분활성도 값을 나타내었다(p<0.05). 수분함량 또한 22.98-28.87%의 범위를 보였으며, 된장과 간장 첨가구에서 대조구보다 높은 수분함량 값을 나타내었다(p<0.05). 육색 측정 결과, 된장, 간장 및 고추장 첨가구에서 대조군보다 낮은 명도 값을 나타내었고, 적색도는 대조구와 고추장 첨가구에서 된장 및 간장 첨가구에 비해 낮게 나타났다(p<0.05). 전단가 및 조직감 측정 결과, 대조구에 비해 처리구에서 낮은 전단가를 보였다. 경도 또한 대조구인 소금 첨가구에서 처리구에 비해 높게 나타났다(p<0.05). 관능평가 결과, 소금을 첨가한 대조구가 6.25로 가장 높은 염도 값을 나타내어 전통장류로 대체 시 소비자들이 느끼는 염도를 줄일 수 있을 것으로 판단된다. 또한 향 및 조직감에서 간장 첨가구에서 가장 높은 값을 획득하였다(p<0.05). 이러한 결과는 종합적 기호도로 이어져 간장을 첨가한 육포가 소금과 된장 및 고추장을 첨가한 육포에 비해 유의적으로 높은 선호도 값을 획득하였다(p<0.05).

임현정,정옥철,김화영,안상일 한국항공우주학회 2015 한국항공우주학회 학술발표회 논문집 Vol.2015 No.4

본 논문에서는 한국항공우주연구원에서 운영 중인 위성과 위험 우주물체와의 충돌가능 예측의 참고자료인 근접데이터메시지(CDM)에 대하여 분석하였다. 미합동우주작전본부(JSpOC) CDM의 개요 및 배포기준과 변수 특징에 대해 기술하였고, JSpOC에서 배포한 각 운영위성에 CDM 개수를 산출하였다. 운영위성의 정밀궤도데이터를 이용하여 충돌 예측 시점까지 전파한 위치와 충돌 예측 시점의 CDM 궤도 위치를 비교하여 정밀도를 확인하였고, 각 위성별로 CDM 생성시점과 충돌예측시점의 시간차에 대한 궤도오차 및 공분산을 분석하였다. In this paper, Conjunction Data Message(CDM) which is used as references of the conjunction prediction between the operational satellite of KARI and space objects was analyzed. The summary, the notification criteria and the characteristic of JSpOC CDM were described, and the number of CDM for each operational satellite from JSpOC was calculated. Using the precise orbit determination of the satellite, the position propagated by the time of closest approach(TCA) and the orbital position of CDM at TCA were compared in order to check the orbit accuracy. The position error and covariance with respect to time difference between TCA and the creation time of CDM is also analyzed.

Aminoglycosides (AG) and vancomycin are frequently prescribed for the treatment of serious bacterial infections. Since both agents have similar pharmacokinetics, it would be desirable to estimate vancomycin's pharmacokinetic parameters by using the patient's measured aminoglycoside pharmacokinetic parameters or vice versa. The objectives of this study were to determine if pharmacokinetic relationships exist between AG and vancomycin with respect to pharmacokinetic parameters in Korean patients in phase Ⅰ and to evaluate the clinical utility of these relationships by applying the derived regression equations to a different patient group in phase Ⅱ. 81 patients in phase Ⅰ and 39 in phase Ⅱ receiving concurrent intravenous vancomycin and AG were enrolled in this retrospective study. Steady-state serum concentrations of AG and vancomycin were obtained and pharmacokinetic parameters (Ke, t_(1/2), Vd, Cl) were calculated using first-order pharmacokinetic equations. In phase Ⅰ, there was significant linear correlation between AG and vancomycin pharmacokinetic parameters. The pharmacokinetic parameters of vancomycin derived from AG were superior to those derived from creatinine clearance (Clcr). Correlation coefficient between Ke, t-(1/2), Vd, and Cl values of AG and vancomycin were 0.862, 0.874, 0.438, and 0.787, respectively. Correlation coefficient between Ke, t_(1/2), Vd, and Cl values of vancomycin and those derived from Clcr were 0.728, 0.622, 0.408, and 0.675, respectively. In phase Ⅱ, the correlation between pharmacokinetic parameters of AG and vancomycin may be beneficial for predicting pharmacokinetics of vancomycin, especially in Ke when AG concentrations have already been obtained. Regression equations derived from correlation between AG and vancomycin were less biased in Ke and more precise in Vd. But, vancomycin's Vd and Cl from current regression equations were slightly overpredicted. Thus, revised regression equations ablout predictions of Vd and Cl, and its prospective evaluation will be completed. In conclusion, regression equations derived from AG may be safety used in predicting vancomycin pharmacokinetic parameters.

경찰의 직무스트레스가 일탈태도에 미치는 영향

임현정,유영재 한국경찰학회 2020 한국경찰학회보 Vol.22 No.4

The police is a profession that requires high morality. Also, it is a criminal justice institution that protects the people based on fairness and reliability. However, despite the effort of police organization’s attempts and changes for integrity, the crime rate of police officer is increasing every year. Also, the reliability of public on police is decreasing every year. Therefore, this study examines the factors leads to police deviance behavior using job stress to help the policy of police deviance control system. In this study, attitude on bribery and acceptable attitude on illegal behavior was set as a dependent variables and job stress as independent variables by reviewing the relevant precedent studies. Also, this study conducted regression analysis based on the survey of 300 police officers located in two police station in Seoul. According to the analysis, there was direct relationship between police’s job stress and police deviance. In other words, police’s job stress was significantly related to the attitude on bribery and acceptable attitude on illegal behavior. This means that when the police officer suffers from job stress, the attitude on bribery and acceptable attitude on illegal behavior also increased. Therefore, this results can be interpreted that police’s job stress from organization has possibility of increasing the police deviance. To, control the police deviance, police organization needs to make effort to reduce the police officer’s job stress by decreasing the stress factors related their job. Also, employing professional counselor will be one of the method to relieve the police officer’s job stress which leads the police deviance. 경찰은 높은 도덕성을 요구하는 직업이며, 공정함과 신뢰성을 바탕으로 국민을 보호하는 형사사법 기관이다. 그러나 청렴도를 위한 경찰조직의 시도와 변화에도 불구하고 경찰의 범죄율은 매해 늘고 있으며 경찰에 대한 국민의 신뢰도는 매년 낮아지고 있는 것이 현실이다. 따라서 본 연구는 경찰공무원의 일탈행위에 대한 적절한 통제방안을 제시하기 위하여 경찰의 일탈태도에 영향을 미치는 요인에 대하여 선행연구를 검토한 후 불법행위에 대한 태도 및 뇌물수수태도를 종속변수로 설정하였고, 직무스트레스를 독립변수로 설정하여 서울 지역에 위치한 경찰서를 대상으로 설문조사를 한 후 회귀분석을 실시하였다. 분석결과 직무스트레스가 불법행위에 대한 태도 및 뇌물수수태도에 유의한 정(+)적 영향을 미치는 것으로 나타났다. 즉, 직무스트레스 수준이 높을수록 일탈적 태도에 대하여 관대해지므로 일탈의 가능성이 높아 질 수 있다는 것이다. 따라서 이러한 연구결과를 바탕으로 직무스트레스를 완화하여 일탈태도를 통제하기 위한 조직적 대체방안을 제시하였다.

Background: The introduction of high resolution sonography has made it possible to detect nodules in the thyroid gland. However, there has been no reliable sonographic sign for distinguishing between benign and malignant thyroid conditions. The aim of present study was to evaluate ultrasonographic (US) parameters in predicting thyroid cancer. Methods: One hundred fifty three patients who underwent thyroidectomy at Kosin Medical Center from January, 2000 to April, 2002 were included in the study. All patients were checked high resolutional US before surgery. Of the 153 patients 89 were malignant tumors and 64 benign. Malignant US parameters were defined as calcification, irregular margin, more taller than wide, and fat line obliteration. Calcification pattern was classified with single, punctated, and amorphous calcification. The US characteristics to predict malignancy were evaluated by means of multiple logistic regression analysis. Results: All of the malignant sonographic parameters such as calcification, 53 (89.8%) were thyroid carcinoma. The incidence rate of malignancy was 55.9% in solitary nodules and 65.7% in multiple nodules (p=0.303). Even though nodule size was less than 1.5㎝, the incidence of malignant tumor was 69.5% (p=0.04). Of 53 malignant nodules with calcification, the incidence of single, punctated, and amorphous calcification pattern was 6 (11.3%), 22 (41.5%), 25(47.2%), respectively. The sensitivity, specificity, positive and negative predictive value, and accuracy of sonographic parameters were 76.4%, 87.5%, 89.5%, 72.7% and 81.0%, respectively. Upon the correlation of US-guided FNA cytology with pathologic diagnosis, the sensitivity of ultrasound-guided FNA cytology in differentiating benign and malignant nodule was 85.9%, the specificity 100% and overall diagnostic accuracy was 91.2%. The sensitivity, specificity, and accuracy of US parameters associated to follicular neoplasm, all were 75.0%. Conclusion : All the malignant US parameters including calcification, irregular margin, and more tall than wide showed high level of sensitivity, specificity and accuracy. Of these parameter, calcification and irregular margin were more significants. The more presence of calcifications with punctated and amorphous pattern could suggest the higher possibility of malignancy. However, further study is needed for clinical application of malignant US parameters in the thyroid tumors.

일반계 고등학교 선택의 결정변인 탐색 : 학교의 진로교육 요인을 중심으로

임현정 한국교육개발원 2013 한국교육 Vol.40 No.1

This study analyzed the main factors involved in the process by which middle school students choose to enter general high schools rather than vocational high schools. In particular, the effects of students' career-related activities on high school choice were examined after controlling for students' academic achievements and family background variables. The results revealed that, while academic achievement had a noticeable effect on the choice of high schools, the magnitude of the effect varied somewhat when accounting for family background variables. Still, students' level of educational ambition and the educational expectations of parents and teachers has been discovered to lessen the influence of academic achievement. This result indicates that students' educational ambitions and the educational expectations of parents and teachers amplified the demand for post-secondary education, which made students choose to go to general high schools rather than vocational high schools. The effects of family background were significant after controlling for student's academic achievements, and the family environment and support from parents also affected the choice of high school, aside from the individual effort of each student. Particularly significant factors were students’ satisfaction with career education, the frequency of counseling, and the diversity of career education. Because choice of high school is the individual student's decision, it should depend primarily on the student's ability, and then on the family environment and parents' opinions. Results from this study indicate that the school's pressure to achieve and career guidance may be additional factors that play a role in the decision. This is why we have to pay more attention to career guidance in schools. 「한국교육종단연구2005」에 참여한 학생들의 고등학교 진학 데이터를 분석하여, 전문계 고등학교 대비 일반계 고등학교에 진학할 확률에 영향을 미치는 다양한 변인들의 영향력을 분석해 봄으로써 계열 선택의 주된 요인이 어디에 있는가를 탐색해 보고자 하였다. 특히, 선행연구를 통해 밝혀진 학생의 학업성취, 가정배경의 영향을 통제한 이후 학생의 진로활동의 영향을 살펴보고, 학교수준에서 학교의 풍토와 진로지도 관련 변인이 유의한 영향을 미치는가를 파악하고자 하였다. 분석 결과, 기존 선행연구와 같이 고등학교 계열 선택에 학생의 가정환경, 부모의 지원과 같은 배경요인의 영향이 유의하였으나 학업성취도의 투입이 가정배경요인의 영향력을 감소시키는 것을 알 수 있었다. 또한 학생, 학부모, 교사의 교육포부 및 교육기대 수준과 학생의 진로교육 만족도와 학교의 개별 상담 정도, 진로프로그램 다양성도 유의하여 학교의 진로지도가 고교 계열 선택에 추가적인 영향을 미칠 수 있음을 알 수 있었다. 이를 바탕으로 중학교 시기의 진로교육이 중요함을 논의하였다.

임현정,김양분,김난옥 한국직업능력개발원 2015 직업능력개발연구 Vol.18 No.3

본 연구에서는 고등학교에서 대학으로 진학하면서 나타나는 진로성숙의 변화가어떤 요인으로 설명될 수 있는가를 파악하고자 「한국교육종단연구2005」 자료를 활용하여 대학 입학 전인 고 2때와 대학 입학 초기인 대학교 1학년 두 시점의 진로성숙도 변화와 유의한 관계가 있는 요인을 탐색하였다. 분석 결과, 진로성숙도는 제반 요인의 영향을 통제한 이후 대학에 진학하면서 향상되었다. 진로성숙도의 하위요인별로 보면, 계획성, 자기이해, 진로행동 영역의 수준은 향상된 반면, 직업태도영역은 유의한 차이가 없었다. 그리고 진로성숙도는 가정의 사회․경제적 배경의영향을 거의 받지 않으며, 고교 및 대학에서의 진로교육 경험, 교사 및 교우관계, 독서, 교내외 활동 참여 등의 영향을 받는 것으로 나타났다. 이를 통해 진로성숙이개인의 독자적 노력뿐만 아니라 학교와 사회의 지원을 필요로 하며 실제 경험과 관계 속에서 성장․발전한다는 것을 확인할 수 있었다. This study aims to analyze the factors influencing changes in career maturity during one’s transition from high school to entering college. The results from the analysis using the KELS 2005 dataset were as follows. First, the career maturity significantly increased as students entered college, when other variables were controlled. Second, as subcategories of the career maturity, planning ability, self-understanding, and career behavior improved by year. But there was no significant change in the attitude toward a job. Third, career maturity was affected by career education experiences, students’ relationships with teachers, reading, and student participation in school activities. In conclusion, it is suggested that support from the schools and communities as well as individual efforts is essential for improving career maturity.
