Objective : The purpose of this study is to summarize the differential diagnosis between allergic and nonallergic rhinitis and suggest management. Methods : We reviewed the current update of medical history and physical examination for allergic and nonallergic rhinitis. Then we analyzed clinical characteristics according to onset age, gender incidence and state of nasal symptoms, etc. Results : 1. Patients with nonallergic rhinitis tend to develop symptoms at a later age(>35 years of age), and there is a female-to-male incidence ratio for nonallergic rhinitis of 2:1 to 3:1. 2. Patients with nonallergic rhinitis report nasal congestion, nasal rhinorrhea and more often report postnasal drip rather than sneezing and itching, which are predominant symptoms of allergic rhinitis. And the nasal mucosa in nonallergic rhinitis usually looks normal. 3. Patients with nonallergic rhinitis have few complaints of concomitant symptoms of allergic symptoms and the absence of other atopic diseases in the patient or in the family supports the diagnosis of nonallergic rhinitis. 4. Common triggers of nonallergic rhinitis are nonspecific irritant exposures and many patients with nonallergic rhinitis find that antihistamines have no benefit. Conclusions : The differential diagnosis between allergic and nonallergic rhinitis is clinical and relies on a detailed medical history and physical examination.

The focus of this study is on the new instructional and pedagogical application of teaching English as a foreign language (TEFL) with technology and by gender. Participants comprised 204 TEFL students in Korea. The study was conducted in the 2017 academic year. For this study, all participants attended English class using technology for three hours a week. Course syllabus, lecture notes, and other study materials were uploaded to the school website. Homework assignments, quizzes, and exams were also distributed through the website. To ascertain whether there are any differential effects from gender on learning English as a foreign language using technology, the quantitative materials included pre- and post-tests. This study also adopted qualitative methods, with structured interviews to obtain participants' comprehensive view of technology-assisted English lessons. Paired sample t-tests and independent t-tests were administered to analyze the quantitative data. The qualitative data were analyzed with the content analysis method. Findings show that both male and female students improved their English-speaking skills using technology. However, no gender difference was found in technology-assisted TEFL. Technology use for learning English also resulted in both genders' positive perceptions of language lessons. Based on these findings, this study yields practical implications for TEFL teachers in Korea.

The purpose of this study was to examine gender differences in the impact of exposure to peer delinquency among elementary school-age students and the mediating effects of aggression. The study utilized 458 cases (220 male students, 238 female students) of data from the 2015 Korea Welfare Panel Study (KoWePS) conducted by the Korea Institute for Health and Social Affairs (KIHASA). The theoretical frameworks used in this study included Bandura's social learning theory, Akers' social learning theory, and Sutherland's differential association theory. The findings were as follows. First, there was no statistically significant effect on peer group's delinquency experience overall, aggression, and delinquency experience by gender. Second, male students' delinquency experience of their peer group had a statistically significant effect on their delinquency, however, this was not true for female students. Third, in the case of male students, aggression was found to mediate the relationship between peer group delinquency experience and their own delinquency, but not for female students. From these findings, we suggest a practical and policy-driven intervention plan, focusing on reducing the contact frequency of delinquency experience and aggression, The purpose of this study was to examine gender differences in the impact of exposure to peer delinquency among elementary school-age students and the mediating effects of aggression.

Age-related changes in larynx can have a direct impact on voice quality and general comfort level. Observations of vocal aging have spanned perceptual, acoustic, aerodynamic, physical, electromyographic (EMG) and histological levels. Evidence of differential vocal aging in relation to gender and physical condition has been reported. Perceptual, acoustic, aerodynamic, kinematic, EMG and histological data document age-related changes in laryngeal structure and function with advancing age. These changes contribute to a functional age-related impact of vocal hypofunction or compensatory hyperfunction. This review will focus on the current understanding of the clinical and cellular changes in the larynx that lead to presbyphonia.

The diagnosis of juvenile rheumatoid arthritis (JRA) is based on patient's age at disease onset, symptom duration, gender, and clinical manifestations. JRA is of unknown origin, begins under the age of 16, and persists for a minimum of 6 weeks. JRA is categorized into three principal types, systemic, oligoarticular and polyarticular. Infection, other connective tissue diseases, malignancy, trauma, and immunodeficiency are discussed as differential diagnoses for JRA. Because of joint damage, focusing on early diagnosis and intervention, a vigorous initial therapeutic approach must be taken in patients who have poor prognostic factors. A multidisciplinary team approach is also important for the care of patients with JRA.

The purpose of this study is to understand and analyze characteristics of using pattern on the physical facilities and fundamental demands about improving factors associated with management of variation type. The teachers of four middle schools are participated through questionnaires with this survey. According to the results, supplemental factors of learning activities, convenient facilities for students, factors with space utilization, moving class and arrangement of similar subject blocks are influential in order on the awareness of teachers for correspondence of variation type. In the analysis of variance based on the sampling factors, significant differences were shown in the factors of attached group, gender, age and managemental experience of variation type. Especially, the factors with moving class and convenient facilities for students are analytically more differential than the other factors, therefore, these factors must be considered in detail.

Objective: The purpose of this study is to investigate the prevalence rate of OSA in subjects whose main sleep complaint is insomnia and to find differential factors of OSA in these insomniac subjects. Method: We reviewed the medical records and polysomnographic findings of patients referred to the Sleep Laboratory at Seoul National University Hospital from January 1996 to December 2002. Four-hundred and seventy subjects complained of insomnia as their main sleep problem (235 males and 235 females, mean age $53.6{\pm}12.4\;years$). First, we investigated the prevalence rate of OSA in these insomniac patients. Second, we compared the clinical and demographic characteristics of the OSA-associated group with those of the non-associated group. Third, we examined whether the degree or presence of differential factors within the OSA group correlate with severity of OSA, as determined by the respiratory disturbance index (RDI). Results: Among 470 insomniac subjects, 125 subjects (26.6%) were diagnosed as OSA by nocturnal polysomnography. OSA-associated subjects were significantly older ($58.4{\pm}12.3\;years$ vs. $51.8{\pm}11.2\;years$, p<0.01), and had significantly higher body mass index (BMI) ($23.4{\pm}3.3\;kg/m^2$ vs. $22.5{\pm}3.1\;kg/m^2$, p=0.44) than non-associated subjects. The OSA-associated group had more subjects with male gender (64.0% vs. 44.9%, p<0.01), hypertension (20.0% vs. 9.3%, p<0.01) or snoring (96.0% vs. 63.5%, p<0.01). Within the OSA-associated group, age had a significant positive correlation with RDI (p=0.01). Conclusion: We found that a considerable portion of patients complaining of insomnia as their main sleep problem were diagnosed as OSA. Snoring, old age, male gender, obesity, and comorbid hypertension were found to be differential factors of OSA in insomniac patients. We suggest that diagnostic efforts including nocturnal polysomnography are needed for insomniac patients with any of the above risk factors of OSA.

Patterns and changes of marriage have drawn much attention as they have been pointed out a key factor of low fertility. Nonetheless, systematic studies on marriage have been quite limited. This study, using recent nationwide survey on marriage and fertility, attempts to explain whether and how intention of marriage would differ between never married men and never married women. The logit regression analysis reveals that the likelihood of planning marriage between both sexes are still different even after controlling demographic characteristics, economic status, household and family background, and attitudes toward sex and premarital cohabitation. Furthermore, important factors affecting the likelihood of planning marriage turns out to be different between men and women. For instance, men with a job is more likely than men without a job to plan marriage. However, for women, the effect of having a job is not found. Such result, with other sex differential effects of living arrangement and attitudinal variable, suggests that the mechanism through which men and women transit from singlehood to marriage would differ. More attention on gender differential should be paid in developing conceptual arguments and conducting empirical analysis regarding marriage and its related topics.

Purpose: From the holistic environmental perspective, individual and environmental influences on low-income children's questionable development were identified and examined as to differences in the influences according to the child's developmental stage of infancy (age 0-35 months) or early childhood (age 36-71 months). Methods: This study was a cross-sectional comparative design using negative binominal regression analysis to identify predictors of questionable development separately for each developmental stage. The sample was comprised of 952 children (357 in infancy and 495 in early childhood) from low-income families in South Korea. Predictors included individual factors: child's age and gender; proximal environmental influences: family factors (family health conditions, primary caregiver, child-caregiver relationship, depression in primary caregiver) and institution factors (daycare enrollment, days per week in daycare); and distal environmental influences: income/resources factors (family income, personal resources and social resources); and community factors (perceived child-rearing environment). The outcome variable was questionable development. Results: Significant contributors to questionable development in the infancy group were age, family health conditions, and personal resources; in the early childhood group, significant contributors were gender, family health conditions, grandparent as a primary caregiver, child-caregiver relationships, daycare enrollment, and personal resources. Conclusion: Factors influencing children's questionable development may vary by developmental stage. It is important to consider differences in individual and environmental influences when developing targeted interventions to ensure that children attain their optimal developmental goals at each developmental stage. Understanding this may lead nursing professionals to design more effective preventive interventions for low-income children.

The purpose of this study was to assess the relationship between drinking patterns and depressive mood, and to understand the factors associated with depressive mood among problem drinkers. Data of 19,878 adults over 19 years of age and older from the third Korea National Health and Nutrition Examination Survey were evaluated by multivariate logistic regression analysis. The risk of depressive mood was greater with higher level of problem drinking in both genders. For male problem drinkers, the factors associated with depressive mood include older age, lower education level, unemployment, high perceived stress, bad subjective health status, and non-married status. For female, higher risk was found in groups with the age of 40-49, lower education level, unemployment, high perceived stress, and bad subjective health status. By early screening of the identified risk factors, progression to mental health problem can be avoided. For preventative measures, differential approach depending on gender is suggested.
