Purpose: This study aimed to determine the influence of injury and/or injured area classification on depression in patients with industrial injuries. Methods: The participants comprised438 patients who consented to participate and completed self-reported questionnaires. Data were analyzed using SPSS/WIN version 22.0 for descriptive statistics, $x^2$ test, fisher's exact test, ANOVA, and post-hoc $Scheff{\acute{e}}$ test. A stepwise multiple regression analysis was used to identify factors influencing depression. Results: The results indicated that the effect of disease classification and injured areas on depression were significantly different in patients with industrial injuries. The results further showed that severe depression was significantly higher in cardiovascular patients and patients with an injured area of the head and waist. The most powerful predictor was age (50~59 years), return to work (reemployment), disease classification (cardiovascular), and injured area (head, including vascular disease). Conclusion: This study showed that the most influential variable of depression in patients with industrial injuries were cardiovascular issues, injury areas of the head and waist, being aged 50~59 years, and reemployment. To reduce depression in these patients, it is important to develop and implement a psychiatric rehabilitation program that helps patients to formulate a concrete plan and goal for recovery, enabling patients to actively engage in their rehabilitation.

Objectives: The purpose of this study was to identify the distribution of diagnostic disease among applicants for shoulder musculoskeletal disease. Methods: In 2020, 47 diagnostic disease applicants were investigated for sociodemographic, health, work, job, and diagnostic disease characteristics. The data were corrected through on-site visits and analyzed using descriptive statistics with SPSS WIN23.0. Results: Most of the applicants were male and elderly. They had high blood pressure(38.3%) and diabetes (21.3%), and the drinking rate and smoking rate were also high. The most common type of employment was daily workers, and it was confirmed that the working condition was poor due to excessive working hours and short rest times. Most of the applicants for shoulder diagnostic diseases were in the construction industry, and the most common diagnostic disease was a rotator cuff tear. Conclusions: It is necessary to develop a musculoskeletal disease prevention program suitable for construction workers to reduce their work-related disease. When establishing a program, business type, task, and diagnostic disease must be considered.

Myostatin is a transforming growth and differentiation factor-${\beta}$ family member that acts as a negative regulator of muscle growth. Previously, mutations in the myostatin gene were known to be related to double muscling phenotypes in cattle. Because myostatin gene is highly related to muscle mass, also meat quality, in cattle, we sequenced whole myostatin mRNA and investigated the SNPs (Single Nucleotide Polymorphisms) in Korean cattle (Hanwoo). The results indicated that Hanwoo had an SNP in nt2385 and this mutation can be a useful marker with further verifications. We also investigated expression patterns of the myostatin gene from various muscle tissues and organs. Northern blotting results indicated that myostatin expression was restricted in muscles with variable expression levels. The results presented here can be used as a valuable information for meat quality related traits and muscle mass in cattle.

To investigate the effects of CaCl2 on artificial induction of antlerogenesis in female deer, various CaCl2 conditions with different concentrations, dosages and times were treated to five female Elk(Cervua Canadensis). After injection of CaCl2 solution to the putative region of antlerogenesis, rate of induction, yield of antler, length of antler, number of point were examined. In regard to the effect of concentration of CaCl2 solution on the induction of antlerogenesis in the female deer, generation of pedicle and antler has not induced under treatment of 2ml and 3ml of 15％ solution, but only pedicle has generated with 4ml of 15％ solution, otherwise generation of pedicle and antler has induced under treatment of 1.5ml, 2ml and 3ml of 30％ solution and 1ml and 2ml of 50％ solution. The yields of antler were 319g in 4ml of 15％ solution, and 1,290g, 513g and 295g in 1.5ml, 2ml and 3ml of 30％ solution, respectively, and 800g and 443g in 1ml and 2ml of 50％ solution, respectively. The yields of antler of 30％ solution and 50％ solution were decreased with increase the dosage volume. The maximum yield of antler was 1,290g at 30％ 1.5ml treatment. The length of antler were 25cm in 15％ 4ml treatment, and 55cm, 51cm and 35㎝ in 1.5ml, 2ml and 3ml of 30％ solution, respectively, and 60cm and 35cm in 1ml and 2ml 50％ solution, respectively. There was a tendency that length of antler became longer as yield of antler were grew. The numbers of point were 2 in 15％ 4ml treatment, and 5, 2.3 and 1 in 1.5ml, 2ml and 3ml of 30％ solution, respectively, and 3 and 1 in 1ml and 2ml of 50％ solution, respectively. The number of point was not related to concentration and dosage of CaCl2 solution, but related to the shape of wound due to the time and method of injection. Consequently, the optimum concentration of CaCl2 solution for artificial induction of antlerogenesis in female elk is 30%.

In this study, 1,495 cases of computerized data collected as disease entities of oral and maxillofacial injuries among patient visiting S university hospital located in Seoul in 2009 were analyzed and following results were obtained. It was found that the injury incidence in male was greater than in female (1.49:1), it occurred most frequently in the age of 7~14 years old (19.6%), and its most frequent cause was falling down (25.9%). Injuries occurred in other place including beach and open-air (24.7%) most frequently, often developed in anterior teeth (43.2%) and posterior teeth (43.1%), their incidence was relatively higher between 15:00~17:00 (10.4%) and 19:00~23:00 (7.1%) O'clock. In the relationship between causes of the injury and the diagnosis based on the international classification of disease), falling, fall, impingement, violence, traffic accident, sports and own making accident caused most frequently lip and oral open injuries (S01.5), open fracture of tooth (S02.51), close fracture of tooth (S02.50), close fracture of mandible (S02.60), close fracture of tooth (S02.50), respectively. From the above results, it is necessary to understand general characteristics of oral and maxillofacial injuries and to consider their trends for the establishment of systematic complement policies and for the performing safety training and public relations activities.

Cellular FOS(c-fos) protein is a transcription factor that forms heterodimers mostly with c-jun family and stimulates the transcription of genes containing AP-1 regulatory elements. This c-fos expression can control growth and differentiation of various precursor cells including myoblasts. The controls by c-fos gene have been identified for affecting skeletal muscle fiber traits which are the key determinants of meat quality in pigs. As a first step for identifying the relationship between c-fos gene and meat quality traits in cattle, we fully sequenced 1,443 bp of Hanwoo c-fos mRNA and analyzed expression patterns from various organs and muscle tissues. The sequence identities of Hanwoo c-fos with that of human, pig and mouse showed 89.8%, 93.3% and 87%, respectively. Analyses of the northern blot showed high c-fos expressions were obtained in spleen and rib muscle from 7 organs and 9 different parts of muscles investigated. These results presented here can be used as a valuable marker for meat quality related traits in cattle with further verification.
