Objective : The restless legs syndrome (RLS) is a common disorder affecting up to 5% to 15% of the general population, in which the incidence increases with age, and includes paresthesia in the legs. The purpose of this study is to investigate the incidence of RLS in spine center and to review clinical manifestations of this syndrome and its current treatments. Methods : Over a period of a year, retrospective medical record review and lumbar magnetic resonance images were performed on 32 patients with RLS in spine clinic who were diagnosed by National Institutes of Health criteria. Affected limbs were classified as five. Two grading systems were used in the evaluation of neural compromises. Results : The incidence of RLS was 5.00% (32/639). There were 16 males (50%) and 16 females (50%). The median age at diagnosis was 55.4 years (range, 25-93 years). There are no correlation between the affected limbs of RLS and neural compromises on the lumbar spine. Conclusion : The RLS is a clearly common neurologic disorder of the limbs, usually the legs. The awareness of this syndrome can help reduce diagnostic error; thereby, avoiding the morbidity and expense associated with unnecessary studies or inappropriate treatments in RLS patients.

Ossified lipoma or osteolipoma are rarely reported. It is defined as a histologic variant of lipoma that has undergone osseous metaplasia. Osteolipoma presents with a dominant osseous component within a lipoma. We report a case of a histologically confirmed osteolipoma on the nuchal ligament independent of bone. The patient was a 51-year-old female who presented with a 5-year history of a painless, progressively enlarging mass on the posterior neck. Computed tomography and magnetic resonance imaging showed a circumscribed mass compatible with fat between the C2 and C6 spinous processes with a large calcified irregular component. The mass with dual components was totally removed under general anesthesia and no recurrence was observed after 6 months of follow-up. We also reviewed the clinicopathologic features of previously reported osteolipomas in the literature and suggest that although osteolipoma is a rare variant of lipoma, it should be considered in the differential diagnosis when a lipoma of the posterior neck mixed with a bony component is encountered.

춘천지방의 청동기시대 유적과 유물은 주로 범람원에 분포한다. 이 지역의 범람원은 대부분 고도가 높아 홍수시에도 물에 잘 잠기지 않는 자연제방으로 이루어져 있다. 자연제방은 주변의 구릉지나 곡간충적지보다 농경에 있어 훨씬 유리한 조건을 갖추고 있다. 청동기시대 춘천지방의 주민들은 사연제방에 거주하면서 농경에 종사했을 가능성이 매우 높다. 자연제방의 지형적인 특성과 토양을 고려하면 당시 이 지역에서는 벼농사보다 밭농사 중심의 농경이 이루어졌을 것으로 생각된다.

Objective : The aim of this study is to analyze the relationship among job stress, depression, and suicidal ideation in firefighters, particularly the mediating effects of depression. Methods : The subjects were 2,136 firefighters in Gangwon-do, who completed the short form of Korean occupational stress scale (KOSS-SF), Korean version of the Beck depression inventory (K-BDI), and the revised scale for suicide ideation (SSI) online in mental health promotion service of firefighters. The data was analyzed with correlation analysis among the variables, and the multiple regression analysis method of Bar-on and Kenny (1986) was used. Results : Job stress showed positive correlations with depression (r=0.493, p <0.01) and suicidal ideation (r=0.296, p<0.01). Depression showed a positive correlation with suicidal ideation (r=0.561, p<0.01). The result of analyzing the mediating effect of depression showed that depression was a full mediator variable between job stress and suicidal ideation. Conclusion : Based on the results, it is very likely that job stress may affect suicidal ideation via depression. These results suggested that the preventive interventions emphasized on depression may be helpful for reduction of suicide in firefighters.

The prognosis of solitary plasmacytoma varies greatly, with some patients recovering after surgical removal or local fractional radiation therapy, and others progressing to multiple myeloma years later. Primary detection of progression to multiple myeloma is important in the treatment of solitary plasmacytoma. There have been several analyses of the risk factors involved in the early progression to multiple myeloma. We describe one case of solitary plasmacytoma of the lumbar vertebra that was treated with surgical decompression with stabilization and additional radiotherapy. The patient had no factors associated with rapid progression to multiple myeloma such as age, size, immunologic results, pathological findings, and serum free light chain ratio at the time of diagnosis. However, his condition progressed to multiple myeloma less than two months after the initial diagnosis of solitary plasmacytoma. We suggest that surgeons should be vigilant in watching for rapid progression to multiple myeloma even in case that the patient with solitary plasmacytoma has no risk factors for rapid progression to multiple myeloma.

Synovial cysts of the cervical spine, although they occur infrequently, may cause acute radiculopathy or myelopathy. Here, we report a case of a cervical synovial cyst presenting as acute myelopathy after manual stretching. A 68-year-old man presented with gait disturbance, decreased touch senses, and increased sensitivity to pain below T12 level. These symptoms developed after manual stretching 3 days prior. Computed tomography scanning and magnetic resonance imaging revealed a 1-cm, small multilocular cystic lesion in the spinal canal with cord compression at the C7-T1 level. We performed a left partial laminectomy of C7 and T1 using a posterior approach and completely removed the cystic mass. Histological examination of the resected mass revealed fibrous tissue fragments with amorphous materials and granulation tissue compatible with a synovial cyst. The patient's symptoms resolved after surgery. We describe a case of acute myelopathy caused by a cervical synovial cyst that was treated by surgical excision. Although cervical synovial cysts are often associated with degenerative facet joints, clinicians should be aware of the possibility that these cysts can cause acute neurologic symptoms.

Purpose - The purpose of this study is to compare and analyze the ordinances of other local governments to propose implications and improvement plans for the ordinances of Chuncheon City. To this end, cases of overseas legislation related to youth labor rights, domestic laws and major policies of the central government were reviewed. Design/methodology/approach - This study mainly utilized literature research methods. In addition, it was based on foreign laws and case analysis, domestic laws and ordinances, and preceding research and data related to government policies. Findings - Chuncheon city ordinances are superior to those of other local governments. However, the details of the establishment of the implementation plan, the actual condition survey, and the establishment of the consultation system are included in the project contents of Article 6, so it is not concrete and clear. And there were no articles related to the labor environment check. Research implications or Originality - It is proposed to make the contents of the establishment of an implementation plan, survey, and consultation system as independent provisions. It is also proposed to establish a new article related to the youth labor environment check. In addition, it is desirable to establish detailed regulations by establishing the ordinance enforcement regulations.

Purpose - This study attempted to predict short-term transportation demand using trains and getting off at Gangchon Station. Through this, we present numerical data necessary for future tourist inflow policies in the Gangchon area of Chuncheon and present related implications. Design/methodology/approach - This study collected and analyzed transportation demand data from Gangchon Station using the Gyeongchun Line and ITX-Cheongchun Train from January 2014 to August 2023. Winters exponential smoothing model and ARIMA model were used to reflect the trend and seasonality of the raw data. Findings - First, transportation demand using trains to get off at Gangchon Station in Chuncheon City is expected to show a continuous increase from 2020 until the forecast period is 2024. Second, the number of passengers getting off at Gangchon Station was found to be highest in May and October. Research implications or Originality - As transportation networks are improving nationwide and people's leisure culture is changing, the number of tourists visiting the Gangchon area in Chuncheon City is continuously decreasing. Therefore, in this study, a time series model was used to predict short-term transportation demand alighting at Gangchon Station. In order to calculate more accurate forecasts, we compared models to find an appropriate model and presented forecasts.

Objective : In Asians, kneeling and squatting are the postures that are most often induce common peroneal neuropathy. However, we could not identify a compatible compression site of the common peroneal nerve (CPN) during hyper-flexion of knees. To evaluate the course of the CPN at the popliteal area related with compressive neuropathy using magnetic resonance imaging (MRI) scans of healthy Koreans. Methods : 1.5-Tesla knee MRI scans were obtained from enrolled patients and were retrospectively reviewed. The normal populations were divided into two groups according to the anatomical course of the CPN. Type I included subjects with the CPN situated superficial to the lateral gastocnemius muscle (LGCM). Type II included subjects with the CPN between the short head of biceps femoris muscle (SHBFM) and the LGCM. We calculated the thickness of the SHBFM and posterior elongation of this muscle, and the LGCM at the level of femoral condyles. In type II, the length of popliteal tunnel where the CPN passes was measured. Results : The 93 normal subjects were included in this study. The CPN passed through the "popliteal tunnel" formed between the SHBFM and the LGCM in 36 subjects (38.7% type II). The thicknesses of SHBFM and posterior portions of this muscle were statistically significantly increased in type II subjects. The LGCM thickness was comparable in both groups. In 78.8% of the "popliteal tunnel", a length of 21 mm to <40 mm was measured. Conclusion : In Korean population, the course of the CPN through the "popliteal tunnel" was about 40%, which is higher than the Western results. This anatomical characteristic may be helpful for understanding the mechanism of the CPNe by posture.
