Purpose: The purpose of this study was to provide basic data for the development of weight control programs to maintain and promote healthy behavior in women college students by identifying their weight control behaviors and factors that influence these behaviors. Method: Data were collected from 300 women student participants and were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression with the SPSS 18.0 program. Result: Weight control behavior showed a significant difference according to participants' gender role identity type. Weight control behaviors were correlated with self-efficacy, body image, objective BMI, and ideal BMI. Factors influencing weight control behavior were self-efficacy (${\beta}$= .449, $p$<.001), secret method for weight loss (${\beta}$= .181, $p$<.001), monthly allowance below 200,000 won (${\beta}$= .156, $p$= .006), weight control support from others (${\beta}$= .124, $p$= .013), eating breakfast (${\beta}$= .119, $p$= .015), and age (${\beta}$= .113, $p$= .023) with R-sq. value of 45.3%. Conclusion: The results of the study indicate that development of interventions for weight control behavior and health education for college women should reflect identified factors influencing weight control behavior and gender role identity.

Purpose: Using food labels has been related to healthy eating habits and positive health outcomes. The purpose of this study is to describe the prevalence of food labels utilization and the association between food label use and obesity related factors. Methods: We conducted a self-reported population-based survey including health behaviors, 24-hour recalls, measurements of body mass indices with 6,266 Koreans aged 10 or older. ${\chi}^2$-test and ANOVA examined differences in demographic factors, health behavioral factors, and nutrition factors in tandem with food label use categories. Multivariates logistic regression was used to estimate association between food label use and obesity factors. Results: The percentages of food label users and non-users who perceive food labels were 21.8% and 48.5% respectively. In the multivariate logistic regression, food label use had significant positive associations with women, age, income, education attainment, and subjective obesity. After adjusting for socioeconomic factors and dietetic treatments, the positive associations between food label use and subjective obesity, weight control, and subjective obesity with objective normal weight remained. Conclusion: In order to improve eating habits and weight management, the obesity population that does not use food labels needs to receive proper nutrition education including food choice and body image correction.

The purpose of this study was to investigate dining-out behavior at ethnic restaurants and its relationship with ethnic restaurant satisfaction based on the food-related lifestyle (FRL) of undergraduate students. A total 306 of questionnaires were analyzed using SPSS ver. 12.0 package. The data were analysed using frequency, chi-square, one-way ANOVA, factor analysis and multiple regression analysis. According to the results of factor analysis, the FRL of undergraduate students categorized into health factor, taste factor, convenience factor and ethnic restaurant satisfaction was influenced by four elements: service & hygiene, food quality & convenience, atmosphere & image and unique culture. In addition, visiting frequency and visiting motivation of all dining-out behaviors at ethnic restaurants were significantly different and the FRL groups had differences in the influence of food quality & convenience, atmosphere & image and unique culture. Futhermore, the health factor of FRL was influenced by all elements of ethnic restaurant satisfaction. The findings indicate that ethnic restaurant owners should provide food with healthy ingredients in addition to unique culture and atmosphere to customers.

We report a novel extension of 840 nm wavelength- based spectral domain optical tomography to in vivo/real-time human middle ear diagnosis. The system was designed to access the middle ear region with a specifically dedicated handheld probe. The real-time displaying feature was mandatory for in vivo imaging human subject with the handheld probe, and the system could provide about 20 frames per second for 2048 pixels by 1000 A-scans without using any graphics process units under the Labview platform. The inner ear structure of a healthy male volunteer was imaged with the developed system with the axial and lateral resolutions of $15\;{\mu}m$ and $30\;{\mu}m$, respectively. The application of the OCT technology to early diagnose otitis media(OM) is very promising and could be another extensive branch in the OCT field because it provides the depth resolved image including tympanic membrane (TM) and structures below TM whereas the conventional otoscope technique only gives asurface image of the TM.

PURPOSE: Selective strengthening of the transverse abdominis muscle (TrA) during abdominal hollowing makes an important contribution to the stability and control of the spine. This study examined the effects of abdominal hollowing exercise (AHE) according to the visual feedback method on the external oblique, internal oblique, and transverse abdominis muscles. METHODS: Twenty healthy subjects were assigned randomly to an AHE with visual feedback from real-time ultrasound image (group A, n = 10), AHE with visual feedback with pressure biofeedback unit (group B, n = 10). Both groups underwent 20 min of AHE with visual feedback once daily, five days/week for two weeks. The changes in the muscle thickness of the TrA, internal oblique abdominal muscle (IO), and external oblique abdominal muscle (EO) were measured by ultrasonography. RESULTS: The thickness of TrA was changed significantly in both groups (p < .05). However, the lowest minimal detectable changes were achieved in Group A. The thickness of the IO and EO muscles in group A was changed significantly, but there were no significant changes in group B. CONCLUSION: Both visual feedback methods were effective for strengthening the TrA muscles selectively. Nevertheless, AHE with visual feedback using real-time ultrasound images may be more useful in trA muscle contraction.

Objective: This study was to resolve the limitations of the experimental environment and to solve the shortcomings of the method of measuring human gait characteristics using optical measuring instruments. Design: A cross-sectional study. Methods: Fifteen healthy adults without a history of orthopedic surgery on the lower extremities for the past 6 months were participated. They were analyzed gait variables using the smart guide and the 3D image analysis at the same time, and their results were compared. Visual-3D was used to calculate the analysis variables. Results: The reliability and validity of the data according to the two measuring instruments were found to be very high; gait speed(0.85), cycle time(0.99), stride time of both feet(0.98, 0.97) stride legnth of both feet(0.86, 0.88) stride per minute of both feet(0.99, 0.96), foot speed of both feet(0.90, 0.91), step time of both feet(0.77, 0.71), step per minute(0.72, 0.74), stance time of both feet(0.96, 0.97), swing time of both feet(0.93, 0.79), double step time(0.81), initial double step time(0.84) and terminal step time(0.76). Conclusions: In the case of the smart insole, which measures human gait variables using the pressure sensor and inertial sensor inserted in the insole, the reliability and validity of the measured data were found to be very high. It can be used as a device to replace 3D image analysis when measuring pathological gait.

Bilateral femoral neck stress fractures have been rarely reported. When diagnosed, they are usually limited to athletes or military personnel. A 35-year-old man, previously healthy, visited the emergency department for right inguinal pain. On physical examination, no external wound, tenderness or limitation of motion were found in either lower extremity. Plain radiography showed normal findings but an magnetic resonance image showed a linear fracture in the femoral neck. In this case, bilateral femoral neck stress fractures were found in a young non-athlete adult with no prior medical history of related injuries. Surgery is generally not performed for stress fractures but considering the patient's early mobilization and the need for quick reintegration into society, surgery was done in this case.

최근까지 Chromameter$^{(R)}$ CR-400, Mexameter$^{(R)}$ M18 그리고 육안평가는 피부색 평가를 위한 주된 평가방법으로 이용되어 왔다. 하지만 본 연구를 통해 피부색의 변화를 평가할 수 있는 객관성 있는 평가방법으로 이미지 분석을 제안하고자 한다. 본 연구에서는 세 가지의 기존 평가방법의 변수들과 이미지 분석을 통해 얻은 V (Value) 값을 이용하여 미백 인체 효능평가를 수행하고 변수들 사이의 상관성을 분석하여 이미지 분석의 신뢰성을 확보하고자 하였다. 효능 평가를 위해 과색소침착으로 고민하는 34명의 시험 대상자를 모집하였고 선정된 시험 대상자들은 8주간의 시험기간 동안 vitamin C가 함유된 5 종류의 미백 화장품을 사용하는 동시에 일주일에 1회 전기이온영동(iontophoresis) 시술을 받았다. 제품 사용 및 시술 전과 8주 후 기존 평가 변수들과 V 값 측정결과를 비교하고 각 변수들 사이의 상관성을 분석한 결과, 제품 사용 및 시술 8주 후 V 값은 Chromameter$^{(R)}$의 $L^*$ 값의 경향과 유사하게 증가하였으며, $L^*$ 값과는 양의 상관관계를 보이는 것을 확인하였다(r = 0.494, p < 0.01). 또한, Mexameter$^{(R)}$의 MI 값(r = - 0.683, p < 0.01)과 육안평가 측정 값(r = - 0.549, p < 0.01)은 V 값과 음의 상관관계를 나타내었다. 따라서 이미지 분석의 V 값의 활용은 기존의 평가방법과 더불어 주관적인 육안평가의 한계를 보완할 수 있는 신뢰성 있는 미백평가 방법의 하나라고 생각된다.
