본 논문에서는 입력된 음성이 남성화자인지 여성화자인지를 구분하는 FFT 스펙트럼 및 LPC 켑스트럼 입력에 의한 성별인식 알고리즘을 제안한다. 본 논문에서는 특히 남성화자와 여성화자의 특징벡터를 비교 분석하여, 이러한 남녀의 음향학적인 특징벡터의 차이점을 이용하여 신경회로망에 의한 성별 인식에 대한 실험을 수행한다. 특히 12차의 LPC 켑스트럼 및 8차의 저역 FFT 스펙트럼의 특징벡터를 사용한 경우에, 남성화자 및 여성화자에 대해서 양호한 남녀 성별인식률이 구해졌다.

It is increasingly clear that student mastery of concepts and skills in geographic education is based on a complex set of variables. Sex and gender are the key variables. Much has been written about biological sex differences in learning, but less attention has been paid to the impacts of socio-cultural gender on learning geography. As such, the aims of this paper are two-fold. First, to examine theories which seek to explain why males and females might differ in their geographic and spatial knowledge or skill. Second, to examine the extent of sex differences and gender traits in the geographic learning. The results of study illustrate clearly that there are more similarities than differences between the sexes. Therefore, there are significant gender differences between the preferences of regions, contents, activities in the secondary geographic learning. The results also provide insights into improving contents and method of geographic education.

This paper proposes a gender recognition algorithm which classifies a male or female speaker. In this paper, characteristic vectors for the male and female speaker are analyzed, and recognition experiments for the proposed gender recognition by a neural network are performed using these characteristic vectors for the male and female. Input characteristic vectors of the proposed neural network are 10 LPC (Linear Predictive Coding) cepstrum coefficients, 12 LPC cepstrum coefficients, 12 FFT (Fast Fourier Transform) cepstrum coefficients and 1 RMS (Root Mean Square), and 12 LPC cepstrum coefficients and 8 FFT spectrum. The proposed neural network trained by 20-20-2 network are especially used in this experiment, using 12 LPC cepstrum coefficients and 8 FFT spectrum. From the experiment results, the average recognition rates obtained by the gender recognition algorithm is 99.8% for the male speaker and 96.5% for the female speaker.

The present study evaluated the SNS addiction tendency, mental health, and the student's adjustment to college life to identify the correlations between each of these independent variables on the dependent variable, the adjustment to university life of undergraduate students. Data were collected from 197 subjects in K university of G city, using a self-administered questionnaire. Mental health was negatively correlated with the adaptation to university life. A significant influence of gender and mental health on the adjustment to college life was found in this sample. These findings are expected contribute to understanding and improving the adjustment to college life of undergraduate students. Based on these findings, it will be necessary to improve mental health and multidisciplinary interventions will be needed to support the adjustment to college life in undergraduate students. In addition, these findings would contribute to the development of programs for student's adaptation to college life.

The purpose of this study is to investigate the differences of the mobile phone overuse by gender and school levels. For this study, 565 middle and high school students in Gyeonggi province answered the self-report survey, 253 students were extracted as an overuse group, and the data were analyzed by one-way MANOVA. The results showed that 'daily disturbance' was a common major factor in gender and school level difference and 'school life disturbance', 'with draw' and 'tolerance' were added in school level difference. Based on the results, this study suggested users' characteristics such as gender and school level should be taken into prevention and treatment of mobile phone overuse.

Purpose : To analyze how the Fourth Industrial Revolution affects the gender gap. Method : This study regressed the relationship between ICT development index, network Readiness index and gender gap in 145 countries all over the world. Results : The ICT development index was not statistically significant, but the network readiness index was positively correlated with female labor participation rate and gender wage equality ratio, indicating that the progress of the $4^{th}$ industrial revolution increased female participation in labor but the wage gap has been shown to intensify. Conclusion : The results verify the hypothesis that the $4^{th}$ industrial revolution led by the information and communication revolution affects the labor market conditions of women.

Objectives : Behavioral and psychological symptoms of dementia(BPSD) represent significant clinical problems, resulting in functional decline, caregiver distress, institutionalization and increased mortality. A recent study showed gender differences have important role in the development of BPSD, but relationship between BPSD and gender has never been studied in Korea. This study was designed to examine whether patients with Alzheimer's disease show gender differences in behavioral and psychological symptoms of dementia(BPSD). Methods : Ninety-eight subjects with Alzheimer's disease were included in this study. We carried out history taking and cognitive assessment for the diagnosis of Alzheimer's disease based on DSM-IV. Cognitive impairment and BPSD were measured using the Mini Mental State Examination(MMSE), Global Deterioration Scale (GDS), Clinical Dementia Rating(CDR) and the Korean Neuropsychiatric Inventory(K-NPI). Independent samples t-test was used to examine the differences across gender in BPSD. Correlation analysis between MMSE, CDR, GDS and NPI was performed using Pearson's correlation coefficient. Results : There were no significant gender differences between the gender in BPSD. We found statistically significant negative correlations between MMSE with NPI total score, and with scores of several sub-domains such as hallucination. Conclusions : This study showed that gender differences in BPSD are not significant. Further research is necessary to identify whether BPSD affect gender differences or individual differences.

본 연구는 사료 내 라이신 수준과 성별이 재래흑돼지육의 냉장기간동안 육질에 미치는 영향을 구명하고자 실시하였다. pH는 저장 5일까지 감소하였으나 7일째에 증가하였다. 그리고 high 처리구에서 가장 높게 나타났으며, high, medium 처리구의 거세돈과 low 처리구의 미경산돈에서 높게 나타났다. 드립감량과 가열감량은 저장기간동안 감소하였으나 라이신 수준과 성별에 따른 차이를 나타내지 않았다. 라이신 수준이 낮을수록 적색도와 황색도 모두 높게 나타났으나 성별에 따른 차이는 나타나지 않았다. 경도와 점착성은 감소했고, 거세돈육의 경도와 점착성이 미경산돈육보다 낮았지만 라이신 수준에 따른 차이는 없었다.

"여성은 수학을 못한다" 또는 "수학적 능력에 있어서 남학생이 여학생보다 우월하다"는 우리 사회의 일반적 통념은 근거가 있는 것인가? 1970년대 이후 구미를 중심으로 외국에서는 교육에서의 성 평등(equity) 문제에 대한 관심이 높아지면서 수학에서의 성별차이(gender difference)에 대한 연구들이 상당히 이루어져 왔다. 그러나 국내의 연구는 한국학술진흥재단의 연구지원을 반아서 수행된 96년부터 98년까지의 3년 연구(권오남, 박경미, 임형, 허라금의 공동연구) 이외에는 거의 전무하다. 이 글에서는 수학적 능력에서의 성별차이라는 논제를 3년 연구의 결과를 중심으로 양적, 질적 연구방법으로 접근하며, 이를 바탕으로 수학교육에서의 양성평등의 과제와 전망을 논의한다.
