The concept of integrated pest management (IPM) first developed in the 1950s, and the concept of economic control via pest management was established in the 1960s. Research on IPM began in the United States and Europe, and IPM studies in Korea started with citrus insects and paddy field pests following the distribution of high-yield varieties of rice. Apple IPM in Korea began with research on pest control using chemical pesticides and pesticides resistant to insect pests, studies on the ecology of insect pests and their natural enemies, and the exploitation of sex pheromones on insect pests. Since the 1990s, IPM research and field projects have been carried out simultaneously for farming households. In the 2000s, the development of pest monitoring and forecasting models centered on mating disturbances, database programs for pests, and networks for sharing information. IPM technology has expanded via the development of unmanned forecasting systems and automation technologies in the 2010s.

Purpose : The purpose of this study was conducted to compare the fear of falling, self-efficacy and fall prevention behavior according to the fall experience of the elderly. Methods : The subjects of this study were 162 elderly in B metropolitan city. The data collection period was from September 10th to November 30th of 2018. The collected data was processed using SPSS 21.0 and was analyzed using descriptive statistics, t-test, ANOVA, Scheffe's test. Results : The mean scores for fear of falling according to the fall experience and no fall experience of the elderly were 2.28±0.63 and 1.84±0.64 respectively and the results showed that fear of falling (t=4.26, p<.001) and self-efficacy of falling (t=3.88, p<.001) were significantly different between the two groups, but the mean scores for fall prevention behavior according to the fall experience and no fall experience of the elderly were 1.63±0.20 and 1.67±0.17 respectively and there was no significantly different in fall prevention behavior (t=-1.16, p=.25). Fear of falling according to the fall experience was significantly different by age (F=3.25, p<.05) and physical activity related to daily life (F=13.22, p<.001). Self-efficacy according to the fall experience was significantly different by age (F=3.03, p<.05), income per month (F=3.74, p<.05) and physical activity related to daily life (F=11.99, p<.001). But fall prevention behavior was no significantly different of general characteristics. Fear of falling according to the no fall experience was significantly different by age (F=3.37, p<.05), marriage status (F=3.37, p<.05), education level (F=5.15, p<.01), income per month (F=3.58, p<.05) and physical activity related to daily life (F=15.71, p<.001). Self-efficacy according to the no fall experience was significantly different by sex (t=2.32, p<.05), age (F=5.20, p<.01), marriage status (F=5.04, p<.01), education level (F=6.55, p<.001), income per month (F=5.99, p<.001) and physical activity related to daily life (F=18.86, p<.001). Fall prevention behavior was significantly different by marriage status (F=3.51, p<.05). Conclusion : The results of this study suggest the following : it is necessary to develop a program that can lower the fear of falling in the elderly and to increase the self-efficacy of falling, and to develop an education program that can improve the elderly's practice of fall prevention behavior regardless of the fall experience and to verify its effectiveness.

Objective: The aim of this study was to investigate 1) the difference in static lower extremity alignment (SLEA) according to a history of lateral ankle sprain (LAS), 2) to identify SLEA factors affecting LAS, and 3) to present the cut-off value and 4) the usefulness and limitations of the SLEA measurement. Method: This case-control study recruited 88 men (age: 27.78±4.69 yrs) and 39 women (age: 24.62±4.20 yrs) subjects with and without LAS. SLEA measurement protocol included Q angle, tibiofemoral angle, genu recurvatum, rear foot (RF) angle, tibal varum and torsion, navicular drop, ankle dorsiflexion range of motion (DF ROM). Independent t-test, logistic regression and receiver operating characteristic (ROC) curve were used for statistical analysis. Results: Men with a history of LAS had significantly smaller Q angles both in standing and in supine position, while women with a history of LAS had significantly greater DF ROM in non-weight bearing (NWB; p < 0.05). Logistic regression model suggests tibial varum (OR = 0.779, p = 0.021) and WB DF ROM (OR = 1.067, p = 0.045) were associated with LAS in men. In case of women, there were no significant SLEA factors for LAS, however, ROC curve analysis revealed standing RF angle (AUC = 0.647, p = 0.028) and NWB DF ROM (AUC = 0.648, p = 0.026) could be affecting factors for LAS. Conclusion: There are differences in SLEA according to the history of LAS, furthermore, the identified items were different by sex. In case of men, tibial varum and WB DF ROM affect LAS occurrence. Standing RF angle and NWB DF ROM of women could be a predictor for LAS. However, since the sensitivity and specificity in most of the SLEA measurements are low, kinematic in dynamic tasks should be considered together for a more accurate evaluation of LAS risk.

Background and Objectives Vocal process granulomas (VPGs) are benign lesions of the larynx, typically contact granulomas (CG) and intubation granulomas (IG). The two diseases are known to have different clinical manifestations despite having the same pathological features. The purpose of this study was to analyze the treatment results for CG and IG and to obtain clinical information. Materials and Method We retrospectively reviewed the medical records of patients diagnosed with VPG between January 2015 and December 2018. The patient's age, sex, medical history, lesion size, lesion type, reflux finding score, response to treatment, duration of treatment, and follow-up period were compared. Results In total, 32 patients were included in the study, of which 18 were CG and 14 were IG. In the CG group, males were dominant (n=15, 83.3%), whereas in the IG group, females were dominant (n=11, 78.6%) (p=0.0009). The response to medical treatment using proton pump inhibitor and steroid inhaler was better in the IG group (11/14, 78.6%) than in the CG group (7/18, 38.9%) (p=0.036). Of the 14 patients who did not respond to medical treatment, 5 received botulium toxin injections, and all 5 had complete remission. The duration of medical treatment was significantly longer in the IG group (p=0.0029). Conclusion IG was more common in female, and CG was more dominant in male. IG had better response to medical treatment using proton pump inhibitor and steroid inhaler than CG.

The reported risk factors for gallstone disease (GD) are old age, female sex, obesity, metabolic syndrome and migrants. Many younger adults tend to live in Jeju City, where transportations are convenient and commercial activities are active. Whereas, older people tend to live in Seogwipo City, because they engaged in fisheries and agriculture. Rates of migrants and old age could affect the prevalence of GD among residents in two regions. Therefore, the purpose of this study was to compare the GD prevalence and analyze risk factors affecting GD including residencies. A total of 13,050 subjects who visited a single health medical check-up center on Jeju Island between 2012 and 2019 were included. We performed univariate and multivariate analysis to identify risk factors for GD. The prevalence of GD among residents were 5.7% in Jeju City and 5.8% in Seogwipo City, respectively. Multivariate analysis revealed that age (P=0.008), body mass index (P=0.044), high-density lipoprotein cholesterol (P=0.006) and gamma-glutamyl transferase (P=0.013) were independent factors affecting GD. The old age, mean higher body mass index, gamma-glutamyl transferase and mean lower high-density lipoprotein cholesterol were independent risk factors affecting GD. However, residencies did not affect the prevalence of GD.

Purpose: This study was based on the Korean Foot and Ankle Society (KFAS) member survey and aimed to report the current trends in the epidemiology, diagnosis, and management of acute Achilles tendon rupture (AATR) over the past few decades. Materials and Methods: A web-based questionnaire containing 34 questions was sent to all KFAS members in October 2021. The questions were mainly related to the clinical experience and preferred management of patients with AATR. Answers with a prevalence ≥50% of the respondents were considered a tendency. Results: Seventy-one (12.9%) of the 550 members responded to the survey. The male sex ratio in AATR was answered mean 78%, and the most common age groups were 30~40 years (n=49; 69.0%), and 40~50 years (n=37; 52.1%), in that order. The most common seasons for the occurrence of AATR were spring (37 cases; 52.1%) and autumn (27 cases; 38.0%). Also, sports-related rupture had an average occurrence of 76.2%. The most important clinical factor to determine the type of treatment was the history of previous injuries, and 75.9% of respondents started conservative treatment in the 2010s. The most preferred protocol of conservative treatment was an orthosis capable of ankle range of motion after casting (68.5%), and 53.7% 'satisfied' and 1.9% 'very satisfied' with conservative treatment. The most preferred surgical method was open repair (80.3%), and the Krackow method (60.6%), and 49.3% of treated patients responded 'satisfied' and 45.1% 'very satisfied' with this treatment. Conclusion: This study gives updated information concerning the current trend of epidemiology, diagnosis, and treatment of AATR in Korea. Both consensus and variation in the approach to AATR were identified using this survey study. This study may raise the awareness of various possible approaches toward AATR and should be used to further establish a standard protocol for the management of this injury.

Objectives: The purposes of this study were to compare the degree of sodium reduction practice and estimate sodium intake by salty food preference. Methods: Sodium reduction practices, salty food preferences and estimated sodium intake were surveyed for restaurant owners (n = 80), employees (n = 82) and customers (n = 727) at the restaurants participating in the sodium reduction project in Daegu, Korea. Estimated sodium intake was performed by examining sex, age, body mass index (BMI), salty eating habit and dietary behaviors. Results: The degree of sodium reduction practice was significantly higher in salinity meter use (P < 0.001), low salt seasonings (P < 0.001) and efforts to make the foods as bland as possible overall (P < 0.001) in the restaurants participating in sodium reduction project than in homes (P < 0.001). The degree of sodium reduction practice appeared lower in the high salty food preference group than in the low-preference group in such items as efforts to make the foods as bland as possible overall (P < 0.05) and washing the salty taste and then cooking (P < 0.05). The high-preference group showed high-salt dietary behavior, including eating all the soup until nothing was left (P < 0.05) more than the low-preference group, but low-salt dietary behavior included checking the sodium content in processed foods (P < 0 .0 5) less than the low-preference group. The high-preference group was higher in the soup and stew intake frequency than the low-preference group (P < 0.05) and much lower in nuts (P < 0.05) and fruits (P < 0.05) intake frequency. The high-preference group had a higher salty eating habit (P < 0.05), salty taste assessment (P < 0.05) and estimated sodium intake (P < 0.05) than the low-preference group. Conclusions: The present study showed that the salty food preference was strongly associated with lower sodium reduction practice and higher estimated sodium intake.

Objective : This study aimed to develop a Korean version of the HLS-EU-Q47 that deals with the concept of health literacy based on the understanding, apply/use, process/appraisal, and access/obtain to health information. The purpose of this study is to confirm the level of comprehensive health literacy of the elderly in Korea using this tool. Methods : After going through the Korean interpretation process of HLS-EU-Q47, the items were confirmed through content validity verification by experts. The completed Korean-HLS-EU-Q47 (K-HLS-EU-Q47) was applied to 254 elderly people in the local community to analyze the degree of internal consistency and reliability. Furthermore, a comparative analysis based on the general variables was conducted. Results : The internal consistency of this tool for the elderly yielded Cronbach's 𝛼 of .81~.91, indicating a high level of reliability. There was a difference in health literacy according to sex and age based on general characteristics. Men had higher health literacy than women, and with increasing age, health literacy decreased. Conclusion : In this study, the K-HLS-EU-Q47 was developed to assess the comprehensive health literacy level of the elderly in Korea. It is expected that the search for ways to maintain a healthier life for the elderly through understanding the health literacy levels of the elderly using the results of this study will become more active.

Objective: The aim of this study was to investigate the effects of dietary supplementation with a multi-strain probiotic (MSP) product containing of Bifidobacterium animalis, Lactobacillus casei, Streptococcus faecalis, and Bacillus cerevisiae on growth, health, and fecal bacterial composition of dairy calves during the first month of life. Methods: Forty Holstein calves (24 female and 16 male) at 2 d of age were grouped by sex and date of birth then randomly assigned to 1 of 4 treatments: milk replacer supplementation with 0 g (0MSP), 2 g (2MSP), 4 g (4MSP), and 6 g (6MSP) MSP per calf per day. Results: Supplementation of MSP did not result in any significant differences in parameters of body measurements of calves during the 30 d period. As the dosage of MSP increased, the average daily gain (p = 0.025) and total dry matter intake (p = 0.020) of calves showed a linear increase. The fecal consistency index of the 2MSP, 4MSP, and 6MSP group calves were lower than that of the 0MSP group calves (p = 0.003). As the dosage of MSP increased, the concentrations of lactate dehydrogenase (p = 0.068) and aspartate aminotransferase (p = 0.081) in serum tended to decrease, whereas the concentration of total cholesterol increased quadratically (p = 0.021). The relative abundance of Dorea in feces was lower (p = 0.011) in the 2MSP, 4MSP, and 6MSP group calves than that in the 0MSP group calves. The relative abundance of Dorea (p = 0.001), Faecalibacterium (p = 0.050), and Mitsuokella (p = 0.030) decreased linearly, whereas the relative abundance of Prevotella tended to increase linearly as the dosage of MSP increased (p = 0.058). Conclusion: The MSP product can be used to reduce the diarrhea, improve the performance, and alter the composition of the fecal bacteria in neonatal dairy calves under the commercial conditions.
