작업일보는 일일 단위로 관리되는 작업수행, 출역, 자재 및 장비 정보 등의 축적을 통해 다양한 관점에서 활용될 수 있는 실적정보를 포함하고 있다. 이러한 중요성에도 불구하고 현장인력 슬림화와 건설정보의 증대로 작업일보 작성에 대한 업무부담이 늘어나고 있는 반면, 이렇게 어렵게 수집된 정보가 축적되지 않고 정보의 활용이 하루 단위의 체크에 국한된 형태를 보이고 있다. 이 연구는 작업일보 상에 나타나는 수행 작업 정보가 공종과 작업위치의 조합으로 표현되고 있는데, 작업위치의 설정이 개인의 선호도나 경험 등에 의해 다르게 표현되기 때문에 정보의 축적이 어렵고 활용도가 떨어진다는 점에 유의하고 있다. 이 연구의 목적은 시설물, 공간, 부위 등의 작업위치 정보를 구성하는 요소정보를 파악하고, 그 요소정보간 유연성 있는 관계 설정을 통하여 작업위치를 유연성 있게 표현함과 동시에, 축적과 재활용이 용이한 작업정보 생성 체계를 구축하는 것이다. 또한 이러한 체계를 이용하여 해당 프로젝트에서 하루 단위로 관리되는 작업정보를 미리 생성하고, 생성된 작업을 관리함으로써 작업일보 업무의 효율성을 높이고자 하는 것이다.

Purpose: The purpose of this study was to identify the influences of hospital employees' daily life posture habits and work-related factors upon musculoskeletal subjective symptoms. Methods: This study was a descriptive survey study. Data were collected using structured a self-report questionnaire between April 1 and May 31, 2015. One hundred and ninety two employees were recruited in three hospitals. The collected data were analyzed using descriptive statistics, ${\chi}^2$ test, t-test, and binomial logistic regression. Results: The habit of leaning on one side and the habit of bending the back in an improper posture are key postures based on lifestyle affecting musculoskeletal subjective symptoms in neck, shoulders, arms, waist, and legs. Labours accompanying repeated arm movements for a long time are key work-related risk factors affecting musculoskeletal subjective symptoms in arms. Conclusion: The results of this study confirmed that, to prevent musculoskeletal diseases, it is necessary to identify and mediate personal factors like daily life posture habits as well as work-related risk factors. They may be utilized as basic materials for education of musculoskeletal health promotion and development of life guidance programs.

Whilst Ecological momentary assessment (EMA) can provide important insights over time and across contexts among rotation workers whose work periods alternate with leave at home, it can also be challenging to implement in the resources and construction sectors. This review aimed to provide a summary of the methodological characteristics of EMA studies assessing health outcomes and related behaviors in rotation workers. Systematic searches in PubMed, Medline, EMBASE, CINAHL, PsycINFO, and Scopus were done to include 23 studies using EMA methods in assessing health-related outcomes and behaviors. EMA designs included daily diary: assessments once per day typically fixed at the end of day (47.8%), within day fixed interval time-based design: assessments on multiple times per day at certain times of day (17.4%) and combination of both designs (34.8%). Studies employed paper and pencil diaries (73.9%) and one or more electronic methods (60.9%): wrist-worn actigraphy device (52.2%) and online-based diaries (26.1%) for data collection. Most of the studies (91.3%) did not report prompting -EMAs by schedule alerts or compliance. Daily diary and within day fixed interval dairies designs are common, with the increasing use of electronic EMA delivery techniques. It is unclear how well participants adhere to assessment schedules, as these are inadequately reported. Researchers should report compliance-related information.

Some regions and states, such as Wyoming, have harsh weather conditions, forcing most transportation projects to be completed under tight schedules. However, construction projects are not only delayed by weather conditions, but also delayed by other factors such as contractor's competency, resource availability, coordination issues, and safety. Also, the construction method, geographical location of the projects, and inability to follow baseline schedules accurately due to the contractor's resource allocation are also reasons for the delay. This paper discusses the main reasons for the delay in the public transportation projects based on Daily Work Reports (DWRs) from five different transportation projects of the last three years in Wyoming. This paper focuses on the inconsistencies of the contractor's schedules to complete the project according to the baseline schedule. First, the authors collected DWRs and baseline schedules from the Wyoming Department of Transportation (WYDOT). Second, the DWR data are compared against the baseline schedules to determine the reasons for delaying their significance. Finally, the paper presents the recommendations to mitigate the effects of delays on public transportation projects as well as to improve the documentation process of DWR data.

본 연구는 2013년 12월 현재 요양병원에 입원생활 중인 노인들 중 환자평가표의 평가구분에서 계속입원중인 환자 평가를 받은 3개월 이상 입원중인 노인들을 대상으로 실질적으로 부양 및 요양간병 시 집중적으로 관심을 가져야 하는 일상생활활동이 무엇인지를 파악해 보고자 하였다. 연구결과, 일상생활사에 관한 의사결정을 할 수 있는 인식기술 상태와 일상생활활동수행능력들 간의 인과관계를 로지스틱 함수를 이용하여 추정한 결과, 일상생활사 의사결정 인식기술 상태가 심하게 손상된 경우에는 노인들에게 실질적으로 부양 및 요양간병 시 '식사하기' 활동과 '옮겨 앉기' 활동에 집중적으로 관심을 가져야 한다는 것을 확인하였다. 또한 '식사하기' 활동과 '옮겨 앉기' 활동 외의 활동들은 일상생활사에 관한 의사결정을 할 수 있는 인식기술 상태보다는 노화나 질병으로 인한 신체적 기능이 떨어져서 나타난 결과로 유추해 볼 필요성이 있을 것이다. 따라서 이 경우에는 부양이나 요양간병 시 도움을 받는 노인들의 인격이나 수치심 등 자존감을 고려하여 수발자들은 행동과 언어에 각별히 신경을 써야 할 것이다.

The excessive exposure to powered hand tools can cause damage to nerves, impair blood circulation, and musculoskeletal damage. The symptoms associated with hand-arm vibration syndrome (HAVS) include numbness, tingling, pain and subsequent reduced dexterity of the hands. This study was performed to report the prevalence of the HAVS and evaluate its related factors among the workers using powered hand tools. Total 282 workers in 11 plants of Kyungki and Inchon areas were examined. A standard symptom questionnaire was developed and administered to collect information on personal characteristics, work history, operating conditions, tool characteristics, and subjective symptoms of HAVS. Mean values (standard deviations) of the age, the duration of powered hand tools used, and the daily hours using powered hand tools were 38.3(8.9) years, 79.3(62.2) months and 6.0(2.6) hours, respectively. 132 workers(46.8%) showed vibration-induced white finger symptoms according to the Taylor-Pelmear classification, and 30 workers(10.6%) were interfered with the work. The results of a multiple logistic regression analysis controlling for age and daily working hours showed that smoking, work duration, weight of tools, and continuous work over 2 hours were significantly associated with the symptom of HAVS.

The main purpose of this study is to establish standard times of several manufacturing processes in a small-sized manufacturing company located in Taegu. This company produces two types of products; single parts and part assemblies of bicycles. Due to lack of the standards on daily or hourly production volumes, the production manager could not assign workers daily production volume at the start of production, and could not exercise tight supervision. The standard times established in this study were much less than the average production times found in the daily production report. Based on these standard times, we calculated the number of machines that a worker can operate properly without bringing overload on him, and established a line balanced production system in each manufacturing process to minimize work-in-process inventory.

Recently, the disaster rate of the construction industry has increased with high-rise, and complexity of the building, unlike the decrease in the disaster rate in other industries. Although risk assessment is performed to reduce the occurrence of disasters, it is difficult to estimate the risks accurately due to activity in which no disaster has occurred, and inconsistencies in the level of details of work. In this study, in order to evaluate the risk of the major activity for the apartment construction work, the activity was identified by referring to the risk assessment model of construction industry type by the KOSHA. The construction work types and activities were consistently organized in level of work into nine work types and 82 activities were through experts consultation. Analyzing the disaster types that occurred during work through KOSHA disaster cases, calculating the probability of disaster occurrence according to the type of disaster, and combining the probability of disaster with the severity of disaster to estimate the risk assessment method was presented. Using the daily report of the construction site of the apartment, the results of a case study confirmed the validity of the risk calculation method presented in this study.

Isolated sphenoid sinusitis is a rare disease in children, and its symptoms are often nonspecific and confusing. Rarely, severe headache can be the first or only symptom of isolated sphenoid sinusitis. New daily persistent headache (NDPH) is a form of chronic daily headache that may have features of both migraines and tension-type headaches. NDPH is difficult to diagnose and requires a multifaceted approach. Here, we report on a 10-year-old boy and an 11-year-old girl who both presented with typical NDPH symptoms. These patients had no nasal symptoms or signs of infection. Neither nonsteroidal anti-inflammatory drugs nor topiramate had any effect on the headaches. Their neurological and ophthalmological examinations were normal. The results of routine blood work, including thyroid function tests, inflammatory markers, complete blood count, tests for viral infection, and a metabolic panel, were normal. A brain magnetic resonance imaging scan showed isolated sphenoid sinusitis. Both patients' symptoms resolved completely after approximately 1 month of oral antibiotics for sinusitis.
