Background: It has been proved that participating in exercise improves colorectal cancer patients' prognosis. This study is to identify barriers to exercise in Korean colorectal cancer patients and survivors. Materials and Methods: A total of 427 colorectal cancer patients and survivors from different stages and medical status completed a self-administered questionnaire that surveyed their barriers to exercise and exercise participation. Results: The greatest perceived exercise barriers for the sampled population as a whole were fatigue, low level of physical fitness, and poor health. Those under 60-years old reported lack of time (p=0.008), whereas those over 60 reported low level of physical fitness (p=0.014) as greater exercise barriers than their counterparts. Women reported fatigue as a greater barrier than men (p<0.001). Those who were receiving treatment rated poor health (p=0.0005) and cancer-related factors as greater exercise barriers compared to those who were not receiving treatment. A multivariate model found that other demographic and medical status were not potential factors that may affect exercise participation. Further, for those who were not participating in physical activity, tendency to be physically inactive (p<0.001) and lack of exercise skill (p<0.001) were highly significant barriers, compared to those who were participating in physical activity. Also, for those who were not meeting ACSM guidelines, cancer-related exercise barriers were additionally reported (p<0.001), compared to those who were. Conclusions: Our study suggests that fatigue, low level of physical fitness, and poor health are most reported exercise barriers for Korean colorectal cancer survivors and there are differences in exercise barriers by age, sex, treatment status, and physical activity level. Therefore, support for cancer patients should be provided considering these variables to increase exercise participation.

Objective : The purpose of this study is to investigate about comparison of Eastern-Western medicine on the acne. Methods : We searched Eastern and Western medicine books for acne. We analyzed these books and examined category, definition, etiology, classification, internal and external methods of treatment of acne. Results : The results were as follows. 1. In Eastern medicine, Acne belongs to the category of the Bunja(粉刺), Jwachang(痤瘡), Pyepungbunja(肺風粉刺). In Western medicine, the other name of Acne is acne vulgaris. 2. In Eastern medicine, the definition of Acne includes manual extraction of comedones and skin appearance. In Western medicine, Acne is a common skin disease during adolescence and a chronic inflammatory disease of pilosebaceous unit of self localization. It is characterized by noninflammatory, open or closed comedones and by inflammatory papules, pustules, and nodules and it affects the areas of skin with the densest population of sebaceous follicles, these areas include the face, neck, back, and the upper part of the chest. 3. In Eastern medicine, the cause and mechanism of Acne arose from the state of internal dampness-heat and spleen-stomach internal qi deficiency due to dietary irregularities and then invaded external pathogen such as wind-dampness-heat-cold-fire in lung meridian lead to qi and blood heat depression stagnation. So it appears in skin. In Western medicine, the etiology and pathogenesis of Acne is clearly not identified, but there are most significant pathogenic factors of blood heat depression stagnation. So it appears in skin. In Western medicine, the etiology and pathogenesis of Acne is clearly not identified, but there are most significant pathogenic factors of Acne; Androgen-stimulated production of sebum, hyperkeratinization and obstruction of sebaceous follicles, proliferation of Propionibacterium acnes and inflammation, abnormaility of skin barrier function, genetic aspects, environmental factors etc. 4. In Eastern medicine, differentiation of syndromes classifies clinical aspects, and cause and mechanism of disease; the former is papular, pustular, cystic, nodular, atrophic, comprehensive type; the latter is lung blood heat, intestine-stomach dampness-heat, phlegm-stasis depression, thoroughfare-conception disharmony, heat toxin type. In Western medicine, it divides into an etiology and invasion period, and clinical aspects; Acne neonatorum, Acne infantum, Acne in puberty and adulthood, Acne venenata; Acne vulgaris, Acne conglobata, Acne fulminans, Acne keloidalis. 5. In Eastern medicine, Internal methods of treatment of Acne are divided into five treatments; general treatments, the treatments of single-medicine and experiential description, the treatments depending on the cause and mechanism of disease, and clinical differentiation of syndromes, dietary treatments. In Western medicine, it is a basic principles that regulation on production of sebum, correction on hyperkeratinization of sebaceous follicles, decrease of Propionibacterium acnes colony and control of inflammation reaction. Internal methods of treatment of Acne are antibiotics, retinoids, hormone preparations etc. 6. In Eastern medicine, external methods of treatment of Acne are wet compress method, paste preparation method, powder preparation method, pill preparation method, acupuncture and moxibustion therapy, ear acupuncture therapy, prevention and notice, and so on. In Western medicine, external method of treatments of Acne are divided into topical therapy and other surgical therapies. Topical therapy is used such as antibiotics, sebum regulators, topical vitamin A medicines etc and other surgical therapies are used such as surgical treatments, intralesional injection of corticosteroids, skin dermabrasion, phototherapy, photodynamic therapy, and so on. Conclusions : Until now, there is no perfect, effective single treatment. We think that Eastern medicine approach and treatment can be helpful to overcome the limitations of acne cure.

The incidence of colorectal cancer has been increasing in many Asian countries including Malaysia during the past few decades. A physician recommendation has been shown to be a major factor that motivates patients to undergo screening. The present study objectives were to describe the practice of colorectal cancer screening by primary care providers in Malaysia and to determine the barriers for not following recommendations. In this cross sectional study involving 132 primary care providers from 44 Primary Care clinics in West Malaysia, self-administered questionnaires which consisted of demographic data, qualification, background on the primary care clinic, practices on colorectal cancer screening and barriers to colorectal cancer screening were distributed. A total of 116 primary care providers responded making a response rate of 87.9%. About 21% recommended faecal occult blood test (FOBT) in more than 50% of their patients who were eligible. The most common barrier was "unavailability of the test". The two most common patient factors are "patient in a hurry" and "poor patient awareness". This study indicates that colorectal cancer preventive activities among primary care providers are still poor in Malaysia. This may be related to the low availability of the test in the primary care setting and poor awareness and understanding of the importance of colorectal cancer screening among patients. More awareness programmes are required for the public. In addition, primary care providers should be kept abreast with the latest recommendations and policy makers need to improve colorectal cancer screening services in health clinics.

Purpose: The purpose of this paper is to provide logical basis on enlargement of toilet floor space for the disabled by "ACT ON GUARANTEE OF PROMOTION OF CONVENIENCE OF PERSONS WITH DISABILITIES, THE AGED, PREGNANT WOMEN. ETC" Revised Enforcement regulation [Asterisk 1] (2018.2.10.) and to help with making plans, designs and establishing policies by conducting experimental study with the enhanced floor area regulations. Methods: We conduct Experimental study, field work and interview for this paper. In experimental study, verification of the effective floor area was proceeded by measuring activity space for people in manual wheelchair, electric wheel chair and electric scooter and also reviewed useable area with the space expanded 0.2m both width and depth. In filed work, conducted an observation what other things (ex. sanitary equipment, hand rail and so on) can also affect the active space as well as effective floor space. In the interview, other problems and requirements that were not revealed were experimental study and observation of field work. Results : it's expected to provide better access to toilets for the disabled with the law revision of effective floor area. But, with the usage increasement of enlarged wheel chair and electric wheel chair, expanding side areas of toilet is also highly likely to be required going forward. Implications : Additional research is required on locations of exists and internal arrangement that effect the usage of toilet. It should be led to Universal design by making additional investigation and verification of the users patterns.

Objective: This research was conducted to determine the breast cancer risk levels of women with and without previous mammography and their beliefs on breast cancer and mammography. Methods: The sample for this descriptive research consisted of women aged 50 years or older who were registered at the Family Health Center in the city center of Erzurum. The research was conducted with a total of 420 women with at least one mammography (210) and without mammography (210) who presented to the center on Wednesdays and Thursdays for any reason between 1 January 2010 and 1 January 2011. Research data were collected using the personal information "Breast Cancer Risk Assessment Form" accepted and recommended by the Turkish Ministry of Health, and the Champion's Health Belief Model Scale for Breast Cancer and Screening (CHBMS). Data were evaluated using percentages and means with the t-test. Results: According to the research data, 89.8% of the women were found to be in the low risk group, 87.6% with and 91.9% without mammography. When the health beliefs of women with and without mammography were compared, it was found that susceptibility, seriouness, motivation, mammography benefit scores were higher among those with mammography (p<0.01). The mammography barrier score average was higher in the group without mammography (p<0.01). Conclusion: Knowing women's health beliefs, which have positive and negative effects on participating in mammography screening, may increase the rate of mammography uptake among women. Moreover, women with high breast cancer risk may be determined by increasing society's level of knowledge on breast cancer and risk factors.

Idiopathic nephrotic syndrome (INS) in children is characterized by massive proteinuria and hypoalbuminemia. Minimal change nephrotic syndrome (MCNS) is the most common form of INS in children. The pathogenesis of MCNS still remains unclear, however, several hypotheses have been recently proposed. For several decades, MCNS has been considered a T-cell disorder, which causes the impairment of the glomerular filtration barrier with the release of different circulating factors. Increased levels of several cytokines are also suggested. Recently, a "two-hit" theory was proposed that included the induction of CD80 (B7-1) and regulatory T-cell (Treg) dysfunction, with or without impaired autoregulatory functions of the podocyte. In contrast to the well-established involvement of T cells, the role of B cells has not been clearly identified. However, B-cell biology has recently gained more attention, because rituximab (a monoclonal antibody directed against CD20-bearing cells) demonstrated a very good therapeutic response in the treatment of childhood and adult MCNS. Here, we discuss recent insights into the pathogenesis of MCNS in children.

Background: Viruses can cause either meningitis or encephalitis. It is unclear why some people suffer from aseptic meningitis, and others acquire aseptic encephalitis when infected with the same viral pathogens. The aim of this study was to compare demographic and laboratory factors between patients with aseptic meningitis and encephalitis. Methods: The demographic and laboratory differences were analyzed according to age, sex, diabetes, hypertension, C-reactive protein in the blood, white blood cell and protein in the cerebrospinal fluid, and glucose ratio (cerebrospinal fluid/blood). Additionally, we analyzed the nation-wide differencesin age between the patients with aseptic meningitis and those with encephalitis in Korea. Results: The patients with aseptic encephalitis were older, more likely to have hypertension, and had higher levels of C-reactive protein than did the patients with aseptic meningitis. However, the numbers of white blood cells in the cerebrospinal fluid were significantly higher in the patients with meningitis than in the patients with encephalitis. Multivariable analysis revealed that age >49 years, hypertension and a C-reactive protein level >5.81 mg/dL were independent and significant variables in the prediction of aseptic encephalitis. Additionally, the patients with aseptic encephalitis were older than those with aseptic meningitis in the nation-wide Korean database. Conclusions: Older age, hypertension, and higher levels of C-reactive protein are useful factors for the prediction of aseptic encephalitis.
