Established and new companies face similar business challenges in achieving performance and competitiveness. Furthermore, several empirical studies using competitive advantage resource-based view theory show that established companies achieve performance and competitiveness with breakthrough innovations. Similarly, new business ventures with limited resources must incorporate breakthrough innovations to achieve performance and competitiveness. Therefore, this study aimed to examine the impact of ambidextrous innovation on new venture performance and competitiveness. It used an online survey to collect data from 178 newly established shipping agency companies in 22 provinces in Indonesia. Data was analyzed using multivariate analysis with WarpPLS 7.0, where the analysis unit was an organization represented by a director. The results showed that ambidextrous innovation positively and significantly affects firm performance and new venture competitiveness. This means that ambidextrous innovation that emphasizes adaptation and development improves the firm's internal business processes, even with limited resources. Moreover, it increases new ventures' competitiveness in responding to threats and taking advantage of market opportunities. These results contribute to the competitive advantage resource-based view theory, specifically for new venture empirical examination. Also, they contribute to practical implications in the transportation business, demonstrating that exploitative breakthrough innovation can improve new venture competitiveness and performance.

Wegener's granulomatosis (WG) is a condition with immune-mediated pathogenesis that can present oral manifestations. This report describes the case of a patient diagnosed with WG 14 years previously, who was affected by persistent pain of non-odontogenic origin after successful endodontic treatment. A 39-year-old woman with WG was diagnosed with pulp necrosis and apical periodontitis of teeth #31, #32, and #41, after evaluation through a clinical examination and cone-beam computed tomography (CBCT). At the first appointment, these teeth were subjected to conventional endodontic treatment. At 6- and 12-month follow-up visits, the patient complained of persistent pain associated with the endodontically treated teeth (mainly in tooth #31), despite complete remission of the periapical lesions shown by radiographic and CBCT exams proving the effectiveness of the endodontic treatments, thus indicating a probable diagnostic of persistent pain of non-odontogenic nature. After the surgical procedure was performed to curette the lesion and section 3 mm of the apical third of tooth #31, the histopathological analysis suggested that the painful condition was likely associated with the patient's systemic condition. Based on clinical, radiographic, and histopathological findings, this unusual case report suggests that WG may be related to non-odontogenic persistent pain after successful endodontic treatments.

The insurance payment plan for dental implants in Korea has been criticized because the payment priority has not been properly established, and the benefits are concentrated among middle-class citizens. In the current study, the relationship between the oral health condition and socioeconomic status of the elderly was analyzed using data from the Korea National Health and Nutrition Examination Survey (KNHANES). This study aims to determine the reason underlying the criticism of the insurance payment plan. The subjects were >65-year-old individuals in the 2010 and 2011 database of KNHANES. Data from 2,812 subjects were analyzed. The socioeconomic status was determined based on edentulousness, molar tooth loss, and presence of 28 teeth. According to the analysis, the average income was 1,560,000 won for edentulous elderly, 1,811,000 won for elderly who had lost molar teeth, and 1,896,000 won for elderly with 28 teeth (p<0.05). In addition, elderly with a low education level demonstrated a poor oral health condition (p<0.001). In conclusion, the insurance plan currently under examination is not properly designed for economically impoverished elderly because the plan only covers 50% of the costs and is limited to implantation of molar teeth only. This plan will not provide practical benefits to elderly with a poor socioeconomic status; therefore, the insurance payment plan needs to be improved so that the appropriate beneficiaries can be targeted.

Stroke is the second cause of death worldwide, although the survival period is increasing after the occurrence of stroke, severe physical disability is caused with aftereffect. Oral inflammation is not limited to the oral cavity, it can cause malignant changes in other tissues and organs. In previous studies, we confirmed the relationship between tooth loss and stroke due to periodontal inflammation. The purpose of this study was to investigate the relationship between oral health and stroke such as oral hygiene behavior, tooth loss and periodontal disease among Korean adults over 40 years of age. This study was analyzed using the 6th Korea National Health and Nutrition Examination Survey (KNHANES) data. A total of 3,389 adults over 40 years of age were analyzed as final subjects. Socioeconomic statuses and oral health status was analyzed using a complex sample analysis technique. Logistic regression was used to analyze the relationship of oral health and stroke, and 95% confidence intervals were computed using SPSS. When the prevalence of stroke according to oral hygiene behavior was checked, the prevalence of strokes was lower in subjects who had a lot of brushings per day and subjects who used oral hygiene products (p<0.05). The risk of stroke was 2.17 times (95% confidence interval, 1.43~3.28) higher in the group with less than 19 remaining teeth, but it was not statistically significant as a result of adjusting for age and sex, income level, education level, drinking and smoking (p>0.05). Loss of teeth was found to be associated with the risk factor of stroke. Therefore, loss of teeth due to periodontal disease is an additional issue that should be considered as a risk factor for stroke.

Breast and cervical cancer are the most common causes of cancer mortality among women worldwide, but they are largely preventable. There are limited data on knowledge and practices on screening methods of breast and cervical cancers among female health care workers in Sri Lanka, in spite of having an organized screening programme islandwide. A cross-sectional survey was conducted among 219 female health care workers including public health midwives (68.9%) selected from 6 districts in Sri Lanka using convenient sampling methods. A self-administered questionnaire was used as a pre-test in a capacity building training programme to collect the data. The mean (SD) duration of work experience of the respondents was 12 years and 52.5% were aged over 35 years. Most (76.7%) were married, and afamily history of cancer was reported by 24.2%. Over 98% knew about self breast examination. Even though 84.1% practiced it, only 47.9% practiced it on a monthly basis. Clinical breast examination and mammography were known by 94.1% and 64.3% respectively. Only 19.2% had undergone a clinical braest examination within one year and 3.6% had ever undergone a mamography. Only 76.3% knew that a Pap smear detects precancerous stage of cervical cancer. Among 169 married workers, 73.4% had never had a Pap smear and only 17.2% had got it done within the preceding 5 years. Among the reasons for not doing a pap smear within 5 years, 47.0% belived it as not nescessary, 17.3% due to fear/dislike, 23.2% as not having symptoms, 3% had not known about it and 3% not known about availability of services. The study findings suggest that the knowledge and practices on breast and cervical cancer screening methods among female health care workers need to be improved. Considering the role that health care workers play in communicating health behaviors to the general public, strengthening health education interventions for this group of females is essential.

Objective : Recently, there is an increasing trend of attachment to physical appearance of individuals in many persons with spread of social concern through mass communication. Domestically, several studies has been performed, but they were limited to obesity mainly for juveniles or female college students. Therefore, purpose of this study were to standardize Body image dysmorphic disorder examination self report with male and female college students in Cheonnan area. Methods : This study were total 825 college students in Cheonan area. Subject group are consist of 393 males (47.6%) and 427 females (51.8%), and the mean age was $22.28{\pm}3.24$ years old. Results : The BDDE-SR had adequate internal consistency (Cronbach's alpha=.93) and test-retest (r=.82) and interator reliability. Four factors were extracted by factor analysis with the Varimax rotation. They were 'the camouflage and comparison factor', 'the self-consciousness and negative self-evaluation factor', 'the avoidance factor', and 'the distressing and embarassment factor'. The total score of BDDE-SR was $50.8{\pm}27.1$, female's score ($59.2{\pm}25.5$) was statistically higher than male's score ($41.85{\pm}25.84$). Conclusion : It is considered that BDDE-SR is reliable instrument for body image dissatisfaction, provided correct information in predicting clinical status of Body dysmorphic disorder that is most largely influenced by individual psychologic factor and family system.

A 25-month-old boy was referred to the hospital due to large head detected on routine physical examination. At visit, dysmorphic facial appearances, including broad nose, prominent forehead, and coarse face, were noted. Nasal obstruction with nasal voice, prominent adenoids, and bilateral middle ear effusions were detected. His abdomen was distended, and liver and spleen were palpated about 3 finger and 2 finger breadths, respectively. He was operated for bilateral inguinal hernias. The motion of both elbow joints was mildly limited on supination and pronation. Urinary level of glycosaminoglycan was elevated and the enzyme activity of iduronate sulfatase in leukocytes was decreased. The mutational analysis of the gene iduronate 2-sulfatase (IDS) revealed c.263G>A (p.Arg88His) mutation. His developmental scale showed delayed development and there was cardiac valvular involvement (tricuspid regurgitation and mitral valve prolapse). After the diagnosis of Hunter syndrome, enzyme replacement therapy started on a weekly basis without progression of any clinical features. Here we report a case of early diagnosed Hunter syndrome detected by large head on routine examination. Thus, it is important to associate Hunter syndrome in the patient with large head especially, if there is the history of bilateral inguinal hernia and prominent adenoids to increase the possibility of early diagnosis and treatment.

Objectives: This study investigated the association between oral health and suicide attempts in adults aged 65 years or older using the 7^th Korea National Health and Examination Survey (KHANES, 2016-2018). Methods: Of the total 24,269 participants of the 7^th KHANES (2016-2018), 1,488 adults aged 65 years or older who had an oral health examination were selected. Variations in suicide attempts with demographic characteristics and perceived oral health status were analyzed using the χ² test, and the association between oral health and suicide attempts was analyzed using the logistic regression model. Results: The suicide attempt rate was higher among older adults with chewing (p<0.01) and speaking (p<0.05) difficulties. The odds ratio for a suicide attempt was 1.05 times higher among those with tooth loss (p<0.05). Conclusions: Our results showed that older adults with tooth loss had an increased risk of suicide. Thus, it is important to prevent tooth loss, in the first place, through proper oral health management. If tooth loss occurs, appropriate treatment should be prioritized to facilitate functional recovery. Finally, national support is required for older adults with limited access to dental care.

Purpose : Sarcopenic obesity is associated with adverse health consequences in females. Nevertheless, there has been limited research on the hazardous components and prevailing rates of sarcopenic obesity among younger women. This study aimed to identify the hazardous components and prevailing rates of sarcopenic obesity in younger females. Methods : This study utilized data based on 2008~2011 from the Korea National Health and Nutrition Examination Surveys by the centers for disease control and prevention. The analysis was concentrated on a subset of 1,520 women aged between 30 and 39 years of age. The participants answered a questionnaire to gather demographic information. They then underwent a physical examination to measure the human detention variables, which was conducted utilizing bioelectrical impedance analysis. The blood pressure and blood laboratory tests were determined using established laboratory protocols for evaluating blood parameters. Results : This study included 1,520 patients aged 30~39 years old. The mean age of the participants was 34.97 (years)±2.74 and the overall prevailing rate was 1.84 %. The hazard components in human dimensions were the height, weight, body mass index (BMI), waist circumference (WC) and skeletal muscle mass index (SMI). The hazard components in biochemical and blood pressure were high fasting glucose, increased triglyceride, elevated total cholesterol, high systolic blood pressure, and increased diastolic blood pressure with p-values <.05. Conclusion : This study examined the hazardous components and prevailing rates of sarcopenic obesity in younger women living in the community. The results contribute to the current body of knowledge on sarcopenic obesity and shed light on possible hazardous components in a younger female population. Based on these findings, there should be increased health and medical attention towards the prevention, management, and health promotion related to reducing risk factors for sarcopenic obesity in younger women.

진단 X선 촬영에 의한 소아 및 성인의 장기 등가선량과 유효선량을 구하는 방법론을 개발하였다. 연령에 따른 체격의 차이가 방사선량 분포에 미치는 영향을 평가하기 위해, 식도를 포함한 4개 연령군의 MIRD형 수학적 모의피폭체를 제작하였다. 두 가지의 전형적인 진단 X선 절차인 흉부 PA와 복부 AP 진단 X선 촬영을 모사하여, 연령별 선량을 계산하였다. 흉부 PA 진단 X선 촬영절차에 의해서 환자들은 대략 0.03mSv의 유효선량을 피폭하는 것으로 나타났다. 복부 AP 진단 X선 촬영절차의 경우 연령에 따라서 0.4에서 1.7mSv의 유효선량을 받는 것으로 나타났다. 한정된 조사장을 갖는 방사선에 대해서 선량을 평가했기 때문에, 장기의 위치와 크기, 모양, 그리고 방사선이 입사하는 표면으로부터의 필이 등이 선량 계산에 상당한 영향을 미쳤다. 따라서 진단 X선의 조사장이나 선질의 조절 등을 통해 방호의 최적화를 위한 노력이 중요한 것으로 나타났다. 본 연구에서 개발된 선량계측 절차는 의료방사선 방호의 최적화를 위한 수단으로 활용될 수 있다.
