This study was carried out to investigate the perception, preference and usage of Korean festival foods of women according to age in Busan. The survey was conducted from October 15, 2012 to November 30, 2012 using questionnaires and the data were analyzed with the SPSS program. In general, younger women (20~30 years old) had a lower interest in Korean festival foods than slightly older women (40~50 years old). Most of women over 40 years of age prepared Korean festival foods at home, but many who were in their 20's (45.9%) and 30's (41.1%) obtained their foods from family and relatives. Overall, 62.5% of the subjects wanted to inherit Korean festival food from family and relatives. The dissemination of information and recipes of Korean festival foods were needed for succeeding to Korean festival foods. The taste score was significantly lower for women in their 20's compared to those over 40. Women under 40 reported a lower ease of cooking compared to women over 50. Tangguk (4.93) on Seollal showed the highest perception degree in the order of Namul (4.91), Tteokguk (4.90), and Sikhye (4.90). Jeon, Yaksik, Sikhye, and Gangjeong were the most highly preferred in every group. The preference degree of Pajeon was significantly higher in women under 40 than in those over 60. Tteokguk and Tangguk were more highly preferred in women in their 30's and 40's compared to the other groups. There was a significant positive correlation between preference for festival food and education level, degree of knowledge, degree of interest, will for inheritance, and will for learning (P<0.01). In conclusion, festival foods rich in local tradition should be developed, publicized and used to educate others. The simplification of cooking methods and the development of processed foods are needed to pass on the traditional food culture of Busan.

Introduction: This study evaluated whether body mass index (BMI) and waist circumference (WC) cut-offs for predicting metabolic syndrome (MetS) were different according to Sasang constitutional type. Methods: Data were obtained from 3,117 South Koreans (20-90 years old), and MetS was defined according to the revised NCEP-ATPIII criteria. Age-adjusted BMI and WC cut-offs were calculated according to Sasang constitutional type (Soyangin [SY], Taeeumin [TE], and Soeumin [SE]), sex, and age (men: ${\geq}40$ vs. <40 years, women: ${\geq}50$ vs. <50 years). Results: The prevalences of MetS were 29.9% (<40-year-old men), 35.1% (${\geq}40$-year-old men), 14.8% (<50-year-old women), and 47.7% (${\geq}50$-year-old women). The BMI ($kg/m^2$) and WC (cm) cut-offs for <40-year-old men were 25.9 and 89.9 (SY), 25.5 and 90.5 (TE), and 21.8 and 86.2 (SE). The cut-offs for ${\geq}40$-year-old men were 23.1 and 88.9 (SY), 25.0 and 89.9 (TE), and 22.2 and 87.5 (SE). The BMI and WC cut-offs for <50-year-old women were 22.5 and 81.2 (SY), 25.1 and 83.0 (TE), and 21.5 and 79.8 (SE). The cut-offs for ${\geq}50$-year-old women were 22.2 and 80.5 (SY), and 25.2 and 89.1 (TE), and 21.9 and 80.3 (SE). Conclusions: The BMI and WC cut-offs for identifying MetS varied according to Sasang constitution type.

Purpose: A variety of short Exeter stems designed specifically for use in performance of total hip arthroplasty (THA) in primary and revision settings have recently been introduced. Some have been used 'off label' for hip reconstruction. The aim of this study is to report clinical and radiological results from the Exeter V40 125 mm stem in performance of primary THA and revision THA. Materials and Methods: This study had a retrospective design. Insertion of 58 (24 primary, 34 revision) Exeter V40 125 mm stems was performed between 2015 and 2017. The minimum follow-up period was two years. Assessment of the Oxford hip score (OHS), EuroQol-5 Dimension (EQ-5D), and radiological follow-up was performed at one and two years. Results: In the primary group, the preoperative, mean OHS was 13.29. The mean OHS was 32.86 and 23.39 at one-year and two-year post-surgery, respectively. The mean EQ-5D-3L scores were at 0.14, 0.59, and 0.35, preoperatively, at one-year follow-up and two-year follow-up, respectively. In the revision group, the mean preoperative OHS was 19.41. The mean OHS was 30.55 and 26.05 at one-year and two-year post-surgery, respectively. The mean EQ-5D-3L scores were 0.33, 0.61, and 0.48 preoperatively, at one-year follow-up and two-year follow-up, respectively. No progressive or new radiolucent lines were observed around any stem at the time of the final follow-up in all patients in both groups. Conclusion: Encouraging results regarding use of Exeter V40 125 mm stems have been reported up to two years following surgery in primary and revision THA settings.

The purpose of this study is to examine differences between 20s and 40s in visuospatial performance and brain activation areas using functional Magnetic Resonance Imaging (fMRI). Eight male college students in their twenties ($21.5{\pm}2.3$ years old) and six male adults in their forties ($45.7{\pm}2.6$ years old) who were graduated from college participated in the study. A visuospatial task was presented while brain images were acquired by a 3T fMRI system. Compared to the 20s the 40s showed lower visuospatial performance. There were more activations observed at the parietal and superior frontal areas at 20s compared to 40s. There were more activations observed at the middle frontal and occipital areas at 40s compared to 20s. The results of this study show that the lowering of visuospatial performance with aging was correlated to the decrease of activation area at the parietal lobe and the change of activation area at the frontal lobe.

Purpose: We defined osteoarthritis of the knee as knee pain and crepitus in over 40 years old. The usual clinical manifestation include pain, stiffness, crepitus and loss of function. Methods: We studied 40 cases of the degenerative arthritis of knee clinically. The body mass index(BMI, weight(kg)/height($m^2$) was used as a measure of obesity. Pain self assessment scale by Million Index in according to age, occupation, BMI. Results: Gender by pain self assessment scale was 6.5 in male and 6.6 in female(P<0.05). The prevalence rates obese was 40%. Occupation by pain self assessment scale was 7.0 in Sitting and 5.7 in Standing(P<0.05). Prevalence was increased with age by pain self assessment scale in aged 40-69 years. Conclusion: It has been known that the obesity is one of the predispsing factors of the primary degenerative arthritis of knee. A flexion weight bearing view of the knee obtained at $30^{\circ}$ to $40^{\circ}$ of the joint flexion may be more sensitive in assessing damages to hyaline cartilage because the knee flexion is an important component of the stance phase.

Background: Gastric cancer, the fifth most common malignancy in the world, usually affects older individuals but can occur in younger age groups. In this study we compared the clinicopathological profile of young patients of gastric cancer with that of older patients. Materials and Methods: It is a prospective study of gastric cancer patients treated over three year period (January 2012 to December 2014). Data of patients were obtained from the medical record. Clinical and pathological characters of younger patients (age 40 years or less) were compared with older patients (age more than 40 years). Results: There were total of 152 patients treated during the study period. Twenty patients (13.2%) were less than 40 years of age and 132 (86.8%) were older. The male to female ratio in younger patients was 1:1.5 whereas in older patients it was 1:0.6. In the younger age group 14 patients (70%) had poorly differentiated adenocarcinoma in contrast to 45% in the older age group (p<0.01). Some 55% of younger and 42% of older patients had stage IV disease at presentation and curative surgery was not possible. Palliative surgery for gastric outlet obstruction or bleeding from the tumor was performed on 25% and 21% respectively. Conclusions: Gastric cancer in young people aged less than 40 years has unique characters like female predominance, unfavorable tumor biology, and advanced stage at presentation. There should be a high index of suspicion of gastric cancer even in young patients.

Background: To evaluate pathological features of head and neck squamous cell carcinoma (HNSCC) and to compare these pathological features in patients younger and older than 40 years. Materials and Methods: All resection specimens of HNSCC between 2010 and 2013 evaluated. Tumor characteristics - grade, location (site) cervical node status, alongwith presence or absence of extranodal extension, lymphovascular invasion, gender and age - were extracted from surgical pathology reports. Results: Among these n=19 patients (21.8%) were 40 years or younger and n=68 patients (78.2%) were above 40 years of age. The mean age was 34 (20-40 years) in the younger group and 56 (42-86) in the older group. The most common location of HNSCC in both groups was the oral cavity. The analysis of histopathological features including grade of tumor, tumor size, extranodal extension and comparison between two groups do not show any significant difference. Conclusions: There are no specific pathological characteristics of HNSCC in young patients. An interesting observation is that exposure to expected risk factors is similar in both groups, in younger patients they have less time to act and yet tumors are the same in terms of tumor size, lymph node status and lymphovascular invasion. Therefore further research is recommended to look for potentiating factors.

Purpose: The purpose of this study was to investigate the correlation between shoulder pain and disability index (SPADI) with participation in badminton and to find the effects of badminton on the shoulder joint. Methods: A questionnaire was answered by 143 people with shoulder pain and disability in badminton clubs located in Busan, Gyeongsangnam-do. Out of the 143 subjects (91 males, 52 females), about half (72 people) were over 40 years old, with 71 people over 50 years old. The questionnaire contained 27 questions involving demographic participation characteristics, playing characteristics, and SPADI. Data analysis was performed using the SPSS statistics program to conduct frequency analysis, cross analysis, the t-test, and one-way analysis of variance. Results: The correlation between badminton career, frequency of play, and SPADI was statistically significant. There was a significant increase in SPADI scores for players over 40 years old. The over 40 year old group with less than 5 years of badminton had a significantly increase in SPADI score. The over 50 year old group showed a significantly lower SPADI score compared with the over 40 group. Conclusion: We suggest that beginner badminton players learn correct posture and badminton skills from professionals, participate regularly, and maintain an appropriate intensity/frequency of badminton.

국내의 시력분포를 조사하기위한 다양한 조사가 있었으나 거주지역주민을 대상으로 한 성인의 시력 통계치가 전무한 실정이므로 본 연구에서는 구리시의 지역주민 중 성인을 대상으로 굴절이상의 통계치를 조사하였다. 시력을 spherical equavalent 기준으로 분류할 때 정시안이 총 대상안의 32.0%. 굴절이상안이 총 대상안의 68%(근시 56.6%, 원시 11.4%)를 차지하는 것으로 나타났으며, 안과병원의 외래환자일 때보다 매우 높은 비정시안의 분포를 나타내고 있다. 전체 굴절이상안 중 근시성 굴절이상안이 83.3%로 1968 년 76.3%, 1975년 76.9%에 비하여 점점 증가하는 추세를 나타내고 있으며, 원시성 굴절이상안은 1968년 19.4%, 1975년 17.3%에 비하여 16.7%로 감소하였다. 굴절이상안의 종류별 분포는 전체 대상안 985안 중 근시성복난시가 전체 대상안 중 32.1%로 가장 많았고, 근시성 단난시 18.2%, 단순근시 14.2%, 원시성단난시 6.8%, 혼합난시 5.0%, 원시성 복난시 4.7%, 단순원시 3.6%의 순으로 나타났다. 등가구면굴절력의 분포를 기준으로 근시성 굴절이상안 중에서 경도 근시가 전체 대상안중 40.2%로 가장 많은 수를 차지하였고, 굴절이상안의 74.3%가 경도근시와 경도원시로 나타났다. 양안 굴절이상도 차이의 분포는 0.5~2.00 Dptr가 전체 대상자 중 29.0 %로 대부분을 차지하였고, 양안 굴절이상도 차이가 2.00 Dptr 이상인 부동시는 전체 대상자의 3.6%였다. 연령별 근시성 굴절이상도의 분포는 20대 대상안중 76.7%, 30대 대상안중 74.0%로 외국보다 매우 높은 분포를 보이고 있으며 이는 우리나라의 20대, 30대 성인들이 중고등학교 때의 과도한 입시부담으로부터 오는 많은 근거리 작업에서 그 원인을 찾을 수 있다. 연령별 원시성 굴절이상도의 분포는 20대 대상안중 2.9%, 30대 대상안중 0.6%, 40대 대상안중 6.3%, 50대 대상안중 16.0%, 60대 대상안중 63.9%로 연령이 증가할수록 점점 증가하는 경향을 보이고 있으며 40대 이후로 급격히 증가하고 있으므로, 우리나라의 노인성 시력변화의 시기는 40대로 추정할 수 있으며 노안의 발생시기 또한 일본의 42세와 비슷할 것으로 추정된다. 우안과 좌안의 굴절력을 비교한 결과 우안이 더 근시쪽의 이상을 나타내었으며 남녀의 굴절이상에서 유의한 차이점이 발견되지 않았다.
