Objectives Osteoarthritis is hard to manage with both conventional and Korean medicine treatment. The core outcome set (COS) to demonstrate the effectiveness of Korean medicine treatment has not been established yet. We aimed to present preliminary data of COS by performing a literature review on the evaluation indices used in existing clinical research. Methods We examined the literature from 2000 to 2017 in two Korean electronic databases (Korea citation index and oriental medicine advanced searching integrated system) by searching for the following 3 terms 'total knee replacement (Korean)', 'total knee replacement,' and 'knee surgery.' We found 333 articles; among them, 50 duplicates were removed. Finally, we selected 160 articles after complete screening. We then extracted measured indices and clinical outcomes from the selected articles and categorized the relevant criteria. Results According to this study, the hospital for special surgery and knee society, range of movement angle, cross leg, Berg balance scale and balance ability, muscle strength, 6 minutes walking test, visual analogue scale, self-efficacy, the 12-item and 36-item short form survey and self-rated health status are the most commonly used outcomes of knee. Conclusions This study found that the several categories after total knee replacement (TKR) are being evaluated in the literature, and we were able to verify the most frequently used evaluation indices in these categories. The results of this study will be used to establish evaluation indices for the treatment of TKR in the future using Korean medicine.

Purpose: This study was to identify international classification of functioning, disability and health (ICF) categories that could be linked conceptually to disability of arm, shoulder and hand (DASH) items and short form of health survey 36 (SF-36) items for persons with shoulder pain. Methods: Linkage between each item in DASH and SF-36 and the categories in the ICF were assessed. The linking process was performed by ten health professionals following the linking rule. One hundred four patients with shoulder pain were enrolled from 12 private clinic outpatient departments and participated in this study. Pearson correlation coefficients were used to assess the relationships between each scale item and the linked ICF code. Results: Thirty DASH items were able to be linked to 30 ICF codes, whereas the 36 items in SF-36 were only linked to 17 ICF codes. General health items included in SF-36 could not be linked to a relevant ICF concept. There was a high correlation between the two measurement tools and the linked ICF codes, DASH and its ICF code list (r =0.91), SF-36-Physical Health and its code list (r =-0.62), and SF-36-Mental Health and its code list (r =-0.72). Conclusion: The results suggest that concepts within each item in DASH can be linked to ICF codes for patients with shoulder pain, however, the concepts in the SF-36 items had limited linkage to ICF codes. The shoulder-specific functional tool, DASH can be expressed with ICF codes and, therefore, its use can promote data standardization and improve communication between professionals.

Objective: For knee osteoarthritis (OA), there is a demand for alternative modalities in order to delay surgery and to avoid the side effects of medications. This study compared the effects of applying seaweed pack and mudpack for the treatment of knee OA. Design: Randomized controlled trial. Methods: Twenty-five patients with knee OA who satisfied the criteria were included. The patients were divided into two groups according to the treatment method: mudpack (n=12) and seaweed pack (n=13). The two groups were treated for 20 minutes, twice a day for five continuous days at the Ocean Healing Center at Wando Island, South Korea. Participants were assessed by clinical scores (Western Ontario and McMaster Universities Osteoarthritis Index, Hospital for Special Surgery Knee Score, Knee injury and Osteoarthritis Outcome Score and 36-Item Short Form Health Survey) and lab results (erythrocyte sedimentation rate, C-reactive protein, insulin-like growth factor-1 [IGF-1], tumor necrosis $factor-{\alpha}$ [$TNF-{\alpha}$]) during the follow-up period. Results: For the most part, clinical scores improved after therapy and maintained improvements for four weeks in both groups (p<0.05). In the seaweed group, $TNF-{\alpha}$ was significantly decreased at two weeks post-therapy (p<0.05). In both groups, IGF-1 was significantly increased immediately post-therapy (p<0.05). There were no statistically significant differences after therapy between the groups in clinical scores and labs. Conclusions: Seaweed packs and mudpacks had similar positive effects for knee OA. Additionally, the seaweed pack group showed decreased levels of $TNF-{\alpha}$ at two weeks post-treatment, which may explain the reduced inflammatory reaction. For rehabilitation therapy, use of seaweed packs may serve as an alternative modality for the treatment of knee OA.

Purpose: The survival rate of pediatric patients undergoing liver transplantation has increased considerably. Despite this, the period after transplantation is still complex and poses several challenges to the recipient's family, which is responsible for care management. Recently, more attention has been paid to the impact of this complex procedure on the quality of life of caregivers. Hence, this study is aimed at assessing the quality of life of caregivers of patients who have undergone liver transplantation and the aspects that influence it. Methods: This was an observational and cross-sectional study. From November 2020 to January 2021, short-form-36 questionnaires and additional questions were given to the main caregivers of children and adolescents who underwent pediatric liver transplantation. Results: Thirty-eight questionnaires were completed and the results revealed a lower quality of life in comparison to Brazilian standards, primarily in the mental domains (41.8±14.1 vs. 51.1±2.8; p<0.001). It did not show a significant association with socioeconomic or transplant-related factors, but it did show a negative impact on parents' perception of the child's health. Parents who reported worse health status for their children had a lower mental quality of life (44.1±13.8 vs. 33.3±12.6; p<0.05). Conclusion: The caregivers of transplanted children have a lower quality of life than those of the local population. Psychological assistance should be routinely provided to parents for long-term follow-up to mitigate potential negative effects on the transplanted child's care.

Objective : This study aimed to estimate the mediating effect of interpersonal problems in the association between depression and smartphone addiction among preadolescence. We verified the gender differences and interpersonal problem subtypes. Methods : This cross-sectional study obtained data from 674 subjects aged 9-12 years. The questionnaire included the Smartphone Addiction Scale-Short Form Version (SAS-SV), the Kovacs' Children's Depression Inventory (CDI), and the Korea Inventory of Interpersonal Problems (KIIP-SC). We analyzed data using Pearson's correlation analysis and evaluated the mediating effect of interpersonal problems. Results : The CDI score showed positive correlations with associated with the SAS-SV and the KIIP. In the total group, the KIIP-PA (Domineering) (b=0.13, 95%CI [0.05, 0.22]), the KIIP-BC (Vindictive)(b=0.07, 95%CI [0.02, 0.14]) and the KIIP-NO (Intrusive) (b=0.07, 95%CI [0.02, 0.13]) significantly mediated the association between the CDI and the SAS-SV. In men, the mediating effect of the KIIP-PA (Domineering) (b=0.20, 95% CI [0.08, 0.35]) was significant. On the other hand, in women, the mediating effect of the KIIP-BC (Vindictive) (b=0.14, 95% CI [0.06, 0.25]) and the KIIP-NO (Intrusive) (b=0.08, 95% CI [0.02, 0.17]) were significant. Conclusion : Understanding the mediating role of interpersonal problems in the association between depression and smartphone addiction may help find the appropriate intervention target.

Background: This study aimed to determine the effects of training on breathing re-education on pain and dysfunction levels, posture, quality of life (QoL), and pulmonary function in patients. Methods: This study included 34 patients with chronic neck pain and upper thoracic breathing pattern were included. The participants were assigned to either the routine physical therapy program (RPTP) (CG; n=17) or RPTP and breathing pattern re-education training (EG; n=17). The CG and EG groups performed RPTP for 40 minutes, and only the EG groups performed breathing re-education training for 10 minutes. Exercises were performed thrice weekly for both groups. Level of pain and dysfunction, posture, QoL and pulmonary function status were assessed before and after the intervention. Results: After four weeks of intervention, numeric pain rating scale (NPRS), Korean version of neck disability index, cranio-vertebral angle, cranial rotation angle, and 12-item short form health survey-physical and mental component summaries had significant differences before and after intervention in both groups (p<.01). However, only NPRS, forced vital capacity, forced expiratory volume in 1s, and maximum voluntary ventilation showed significant interactions between the two groups and measurement time (p<.01). Conclusion: Breathing re-education training and RPTP may be optimal for patients with chronic neck pain and may be more effective in improving neck pain and pulmonary function.

Background: Studies on the association between occupational stress and depression have been frequently reported. However, the cross-sectional designs of studies limited insight into causal associations. In this study, we investigated the longitudinal association between occupational stress and new-onset depression among employees in a single manufacturing plant. Methods: The annual health checkup data of employees at a manufacturing plant in Korea were collected. A total of 1,837 male employees without depression who completed a health checkup during two consecutive years were included. Occupational stress was measured using a short form of the Korea Occupational Stress Scale (KOSS-SF), and depression was assessed using a Patient Health Questionnaire-2. The association between occupational stress change over the two years and newly developed depression was investigated using two logistic regression models. Results: Across all sub-factors of KOSS-SF, employees who reported increased occupational stress had a higher risk of new-onset depression. Newly developed depression was significantly associated with job demand (odds ratio [OR]: 4.34; 95% confidence interval [CI]: 2.37-7.96), job insecurity (OR: 3.21; 95% CI: 1.89-5.48), occupational climate (OR: 3.18; 95% CI: 1.91-5.31), lack of reward (OR: 2.28; 95% CI: 1.26-4.12), interpersonal conflict (OR: 2.14; 95% CI: 1.18-3.86), insufficient job control (OR: 1.93; 95% CI: 1.05-3.56), and the organizational system (OR: 1.84; 95% CI: 1.01-3.36). Conclusions: For every sub-factor of the KOSS-SF, occupational stress increase and persistent high stress were associated with the risk of developing new-onset depression. Among the seven sub-factors, job demand had the most significant effect. Our results show that occupational stress should be managed to promote employee mental healthcare.

Objective : To report the effects of a specific intervention, the Interactive Metronome$^{(R)}$ (IM), on timing, attention and motor function of a children with ADHD. Methods : The study is case reports about two boys with ADHD. One boy who is born 2008 is attending general elementary school as a first year student (case 1), and another boy who is born 2001 is attending general elementary school as a second year student (case 2). For each case subject, IM training was provided during 3 weeks, from January 2015 to Febrary 2015. Evaluations were performed pre- and post-intervention in order to exam timing, attention and motor skills. The measurements uses in this study are Long Form Assessment (LFA) for the timing, RehaCom screening module for the attention, and Bruininks-Oseretsky Test of Morot Proficiency, second version (BOT-2) for the motor function. Results : The timing function was improved in both cases since both showed reduced response time for all motor tasks of LFA. In terms of attention, case 1 showed improvement of visual attention division, neglect and response Inhibition, and case 2 showed improvement of sustained attention. Lastly, in the BOT-2, case 1 showed improved the percentile rank of short (from 42%ile to 96%ile), and case 2 also showed similar improvement (from 21%ile to 66%ile). Conclusion : This study provides positive evidence that the Interactive Metronome$^{(R)}$ training has positive power to facilitate several body functions such as timing, attention and motor control of children with ADHD, through two case studies.

Database correctness is guaranteed by standard transaction scheduling schemes like two-phase locking for the context of concurrent execution environment in which short-lived ones are normally mixed with long-lived ones. Traditional syntax-oriented serializability notions are considered to be not enough to handle in particular various types of transaction in terms of duration of execution. To deal with this situation, altruistic locking has attempted to reduce delay effect associated with lock release moment by use of the idea of donation. An improved form of altruism has also been deployed in extended altruistic locking in a way that scope of data to be early released is enlarged to include even data initially not intended to be donated. In this paper, we first of all investigated limitations inherent in both altruistic schemes from the perspective of alleviating starvation occasions for transactions in particular of short-lived nature. The idea of two-way donation locking(2DL) has then been experimented to see the effect of more than single donation in distributed database systems. Simulation experiments shows that 2DL outperforms the conventional two-phase locking in terms of the degree of concurrency and average transaction waiting time under the circumstances that the size of long-transaction is in between 5 and 9.

Spermatogenesis and reproductive cycle of the razor clam, solen grandis, were investigated monthly by histological and cytological observations. Samples were collected from natural intertidal population at Oshik-do, Kunsan, Korea, for one year, beginning from January to December, 1993. solen grandis is dioecious. Morphological structures of the spermatozoon of this species ar esimilar to those of other bivalve spermatozoa having a primitive type; i.e., a small head, a cap-shaped acrosome and a short mid-piece with four mitochondria surrounding axial filament. The head of spermatozoon is approximately 2 \mu m in length and sperm tail is about 20 \mu m long. The axoneme of tail flagellum consists of nine pairs of peripheral microtubules at the periphery and a pair of central microtubules at the center. Four spherical mitochondria form the paranucleus. Spawning occures once a year between early June and July, and the main spawning was observed in July when seawater temperature reaches above 20 \circ C. The reproductive cycle of male razor clam can be divieded into fivesuccessive stages; early active (December to january), late active (January to march), mature (March to early August), partially spawned (June to July), and spent/inactive stage (August to December).
