Saliva have many important functions in the maintenance of oral health. Saliva contains protective components, antibacterial enzymes, and other rubricating glycoprotein elements. When the salivary flow decreases of the salivary composition changes, a normally healthy mouth can become susceptible to caries, periodontal disease, and mucositis, and other diseases. Salivary peroxidase system acts as an antimicrobial factor in the oral cavity, having a role in the prevention of dental plaque accumulation, dental caries and gingivitis. Recently, this enzyme system has been introduced by many researchers in the form of toothpaste, mouthwash or moisturizing gel for use in patients with various disease states . The author prescribed the peroxidase system containing gel (Oralbalance) to the 18 Burning Mouth Syndrome (BMS) patients for 1 week and investigated the changes of the subjective symptoms, $HOSCN/OSCN^-$ levels of unstimulated whole saliva, and the salivary flow rates. The obtained results were as follows : 1. The patients reported decrease in all symptoms of BMS after the use of peroxidase system containing gel, particulary, a significantly higher decreases of dry mouth and burning symptoms. 2. Decreased $HOSCN/OSCN^-$ levels of unstimulated whole saliva were detected in the patients with BMS after the use of perosidase system containing gel for 1 week. 3. There was no difference between the flow rates of unstimulated whole saliva before and after uses of peroxidase system containing gel for 1 week.

Background: Pregnancy-related low back pain (PLBP) has fewer systematic guidelines than pregnancy-related pelvic girdle pain, previous studies have not evaluated physical therapy for this ailment in Korea. Objects: We aimed to provide a detailed account of clinical decision making by Korean physiotherapists while treating PLBP. Methods: In total, 955 questionnaires were distributed mainly in places of continuing education held by the Korean Physical Therapy Association from April to July 2019. The same questionnaire was posted on a website used by physiotherapists. We collected subject information, a specific Vignette typically represent symptoms of PLBP, and responses to multiple questions about decision making, subjective recognition and interest level in the field of women's health physiotherapy (WHPT). Results: The overall response rate was 56% (n = 537); of these, responses to 520 questionnaires were analyzed. Most respondents chose various combinations of physical therapy methods. There were significant differences in subjective recognition levels of WHPT according to gender (p < 0.05), age (p < 0.01), education level (p < 0.01), and clinical experience (p < 0.05). There were significant differences in interest according to gender (p < 0.01) and education level (p < 0.01). With respect to the types of treatment, significant differences were noted in selective rates for "manual therapy", "pain control", and "supportive devices" based on gender. Manual therapy tended to be chosen more with increasing age and clinical experience. With increased education level, there were fewer choices for the use of pain control. Conclusion: This is the first data on how Korean physiotherapists manage PLBP patients using the vignette method. We were able to recognize the Korean physical therapist's decision on PLBP patients, and observed statistically significant correlations. This may aid in developing future research and education plans in the WHPT field.

Objectives: To investigate and analyze the assessment indicators and tools used in clinical practice to assess Korean medicine (KM) treatment for infertility, and to establish a basis for assessment tools to diagnose and assess infertility. Methods: Relevant studies published until March 2023 were extracted from Pubmed, Research Information Sharing Service, and National Digital Science Library databases. Results: Sixty-four studies comprising 4,105 patients were included. We investigated pregnancy outcomes, and assessed pregnancy- and childbirth-related factors, overall health, reproductive health, and mental health. Pregnancy result was most common primary outcome. Ongoing pregnancy, stillbirth, miscarriage, and ectopic pregnancy rates were suggested as indicators of pregnancy and childbirth-related assessment. Overall health was most commonly assessed with Likert and Visual analogue scale (VAS). Among reproductive health variables, menstrual history was most frequently assessed. Moreover, indicators such as reproductive function, sexual intercourse, and gynecological disease were assessed. The Infertility Stress Scale and the Fertility Quality of Life tool (FertiQoL) were used to assess mental health. Conclusions: Subjective scales and objective assessment tools, such as the Likert scale and blood tests/ultrasonography, respectively, are used to assess KM infertility treatment. Inconsistent assessment tools make quantitative analyses more challenging. The development of a standardized mental and physical function assessment questionnaire with confirmed reliability and validity ensure the effectiveness of KM infertility treatment, and promote future studies on infertility treatment.

농업인의 안전보건 정책 수립에 있어 농작업 재해 규모 및 특성 파악뿐만 아니라 손상 부담 평가도 중요하다. 본 연구에서는 농작업 재해자를 대상으로 주관적인 손상 부담 종류 및 그 특성을 파악해 보았다. 2013년 농업인 업무상 손상 조사에서 파악된 재해자를 대상으로 손상 이후 발생되는 부담을 의료비등 직접 비용과 관련된 1개 항목과 생산성 감소, 인건비 증가 등 간접 비용과 관련된 5개 항목으로 파악하였다. 항목별 분포를 비교하였고, 로지스틱 회귀분석을 통해 농업인의 특성 및 농작업 손상 특성에 따라 부담 항목에 차이가 있는지 살펴보았다. 457명의 농작업 재해자에서 주관적 손상 부담중 '치료기간 중 일을 쉼(휴업)으로 인해 농업에 차질'이 가장 많았으며, 다음으로 '가족에 농업 활동 과중 부담 초래', '치료비로 인한 가계 압박', '작업이 지체되어 생산물의 품질 저하', '고용 인건비 증가', '농업 규모 축소'순이었다. 주관적 손상 부담 항목별로 영향을 미치는 주요 특성은 다음과 같다. '치료기간 중 일을 쉼(휴업)으로 인해 농업에 차질'은 연령, 재해 발생시기, 휴업 치료 기간, 농기계 사용여부이며, '가족에 농업 활동 과중 부담 초래'는 가족수, 농작업 기간, 휴업 치료기간이었다. '치료비로 인한 가계 압박'은 입원 치료 여부와 년간총수입에 따라 차이가 있었다. 기존에 신체 제한이 있었던 경우에는 모든 항목의 주관적 손상 부담이 증가하였다. 우리나라 농작업 재해자의 경우, 의료비와 같은 직접 비용에 대한 부담보다는 간접 비용에 대한 부담이 더 높은 것으로 파악되었고, 농업인의 특성 및 농작업 재해 특성 따라 부담 항목별로 차이가 있음을 알 수 있었다. 농작업 재해가 발생한 농업인에 대한 지원에 있어 간접 비용 부담을 줄이려는 목표와 함께 구체적인 방법이 마련되어야 할 것으로 판단된다.

Objectives: In recent days, the problem of odor pollution in community near Sihwa Industrial complex, Kynuggi Province is becoming of significant public concern. We have investigated the health effects of the Sihwa residents from odor pollution comparing with other less polluted areas. Methods: The Ansan and Kuri Cities were selected as control areas. The parents of the elementary and middle school students in these three areas were surveyed with structured questionnaire twice, Nov 1997 and Jure 1998 each. As a exposure index, the ambient air concentrations of five major air pollutants(particulates, $O_3,\;SO_2,\;NO_2$, CO) and subjective odor perception were used. We have focused health outcomes such as the prevalence of nonspecific irritant symptoms, respiratory disease among family members and the score of qualify of life(QOL). Results: Although the mean concentrations of major air pollutants except particulates were similar or lower in Sihwa than other areas, the odor perception rate and the monthly odor perception days were significantly higher. It suggested that odor producing chemical compounds are the major source of environmental pollution problem. There were higher prevalence rates of nonspecific irritant symptoms and respiratory disease among family members in Sihwa than other control areas. The QOL score was also lower in Sihwa. The odor perception proved to be a most important factor in reporting adverse health effects and lowering the QOL score. Conclusion: The residents living near Sihwa industrial complex were suffering from more adverse health symptoms and poorer QOL status than control areas. And it may be due to environmental odor pollution from industrial complex. Therefore, further research will be needed for monitoring of the responsible chemicals emitted from industries.

Objectives: There is higher rates of experience of suicide ideation and suicide attempt of adolescents in the Lima and Callao region compared with the results of the epidemiological study (2013) conducted by Peru National Institute of Mental Health and the Global School-based Student Health Survey (2010) which is was conducted among adolescents across all regions of Peru. Based on the PRECEDE model, this study analyzed the prevalence and the factor associated with the suicide attempt among the adolescent in a poor urban area in Peru. Methods: A stratified random sampling was used for the survey to select study participants from the 6 secondary schools based in Comas or Callao. The survey was conducted November 25th and December 4th in 2015 and a total of 738 individuals included in the analysis. In order to analyze factors influencing suicide attempt, comparison of predisposing factor, reinforcing factor, enabling factor, behavioral factor, environmental factor, psychological factors by suicide attempt and suicide risk group were identified through the chi-square test and hierarchical logistic regression. Results: Results showed that those who reported having less parental understanding, less time spent with parents, and 'almost none/none' for parental affection had more experience of suicide attempt and were more likely to sort into the high suicide risk group. Also, a greater proportion of those with the experience of suicide attempt had more experience of smoking and alcohol consumption, and experience of physical abuse and feeling insulted and depression in comparison to that of those without experience of suicide attempt. Variables that had a significant effect on suicide attempt included depression, subjective happiness, smoking experience, sexual intercourse, involvement in fight, parental affection, and gender (male). Conclusions: The results of the current study can serve as grounds for the necessity of acknowledging that adolescent suicide does not simply depend on a couple of factors, but arises from situations in which individual, home, school, social factors influence one another, and therefore adolescent suicide should be prevented and addressed through a multi-dimensional and integrated approach.
