The purpose of this study was to examine the organization socialization process of engineering novice for the learning and adaptation. Qualitative case study was performed with 5 participants and the collected qualitative data were analyzed using funnel-like method. The findings showed that the organization socialization process proceed in three steps-anticipatory, encounter, and metarmorphosis. Engineering Novice look at the whole organization socialization proces of organization culture and job maladjustment, and the relationship between internal and external organizations to overcome the difficulties arising from the community through the process of becoming a full participant. Socialization of engineering novice is ultimately the organization to respond to new situations and changes in the learning process takes place in the process, talking about a major resource for human resources. This enables organizations to socialize and harmonious human relationships within the organization so that it can be more important than anything else.

The purpose of this study was to evaluate the difference in grip force and angular kinematic variables between elite (handicap${\leq}2$) and novice golfers. Three-dimensional motion analysis system with synchronized grip force measurement system was used. The participants consisted of two groups based on their playing ability: 10 elite golfers and 10 novice golfers. Each subject performed 5 putting strokes at the distance of 1, 3, and 5m with randomly selected order. During entire putting phase, elite group showed relatively constant grip force but novice group showed continuously increasing grip force pattern. There existed a clear difference in the trajectory of shoulder line between two groups. As for novice group the rotational center did not converge into one point, for elite group the rotational center converged into precise single point. And there was a clear difference pattern in anterior-posterior directional movement at shoulder between two groups. These difference might be helpful for improving consistent putting skills.

본 연구에서는 초보운전자의 교통사고 위험성을 줄이고 초보운전자 교육프로그램 개발의 기초자료를 제공하기 위하여 초보운전자에 대한 심리적 특성 및 운전행동에 관한 분석을 실시하였다. 이때 초보운전자의 심리적 부분은 위험인식정도 및 교통상황 이해도를 확인하는 설문조사를 실시하였으며 주 내용은 위험예측 및 예측불허행동에 관한 특성별 범주로 분류하여 파악하였다. 그리고 차량시뮬레이터를 활용하여 초보 및 일반운전자와의 운전행동 특성을 비교 분석하고 통계결과를 토대로 초보운전자의 실제 운전행동에 있어서의 안전진단과 교통안전교육 기초연구의 방향성을 제시 하였다. 본 연구 분석결과, 운전자의 위험예측, 과속, 위반, 정보제공생략, 갑작스러운 변화, 사고건수 모든 부분에서 초보운전자가 일반운전자에 비해 높은 평균값이 나타났다. 또한 초보운전자가 일반운전자에 비해 통계적으로 유의한 위험수준을 보여주었는데 확인된 대상은 위험예측능력, 위반, 갑작스러운 변화, 교통사고건수이었고 그 이외의 과속 수준과 정보제공생략 수준은 초보운전자와 일반운전자 모두 유사한 결과를 보여주었다. 그리고 차량시뮬레이터 실험 결과는 초보운전자가 일반운전자들에 비해 전반적으로 운전 수행능력이 저조한 것으로 나타났다. 특히 충돌횟수에서의 확연한 차이를 보여주었는데 이는 초보운전자들이 일반운전자들에 비해 복잡한 도로교통 상황에서 운전경험과 학습능력이 부족하기 때문인 것으로 판단된다. 한편 초보운전자들은 일반운전자들에 비해 속도조절 능력, 위험예측 능력, 도로교통상황에 대한 인식 및 대처능력 등 전반적인 운전기술의 부족으로 인해 주행안정성이 낮은 것으로 분석되었다. 이러한 결과는 초보운전자들이 일반운전자에 비해 안전운전교육 학습기회의 결여와 운전경험 미숙 등에 따른 것으로 판단되며 운전 상황에 대한 위험예측능력이 낮은 것으로 해석할 수 있다. 결론적으로 이러한 분석결과는 실제 운전상황에서 초보운전자 자신뿐만 아니라 타인에게도 위험 요소로서 작용할 가능성이 높으므로 적절한 안전대책이 필요한 것으로 판단된다.

The validity of the results from observational methods such as RULA, REBA, OWAS has been one of major concerns due to their subjective characteristics in determining the posture of interests. There have been many studies regarding validity of the results from each checklist. However, most studies provided only fragmentary rather than comprehensive results in nature. This study specifically tried to analyze consistency of novice user based on intra-observer consistency and sensitivity of industrial types during MSDs(Musculoskekltal Disorders) evaluation with major checklists. In this study, twenty two novice subjects were participated to conduct MSDs evaluation for the forty five jobs from three types of industries(automobile, electronics, hospital). The main results for this study were summarized as follows; 1) The action level based on RULA was always higher than that from REBA and OWAS for all three types of industries., 2) The order of consistency from novice users was OWAS(72.7%(kappa=0.57)) RULA(54.3%(kappa=0.41)), REBA(41.0%(kappa=0.34))., 3) The percentage of agreement between 2nd and 3rd trials was higher than those between 1st and 2nd trials and between 1st and 3rd trials irrespective of industrial types during using RULA and REBA., 4) The average score of automobile industry was higher than those of hospital and electronics industries., 5) The types of jobs associated with five body parts(A1(Front), A2(Interior), A3(Rear), A4(Lower), A5(Door)) in automobile industry showed statistically significant differences in terms of MSDs scores for the body parts considered in each checklists.

PURPOSES : This study deals with first traffic violations occurred by novice drivers, which may be associated with traffic accidents. The objective of this study is to identify what kinds of drivers' characteristics influence on duration till the first traffic violation. METHODS : For the study, Survival Analysis and Cox proportional hazard model, that are usually used in the medical field, were employed. Survival Analysis was conducted to investigate whether there exist differences in survival duration by each covariate, whereas Cox proportional hazard model was used to identify significant factors that affect survival duration till novice drivers violate traffic regulations for the first time after getting a driver license. RESULTS : The results of Survival Analysis indicate that female, age (less than 21), low-frequency examinee of written exam, and non-crash involved drivers have longer duration till the first violation compared to male, greater than 21 years old, high-frequency examinee of written exam, and crash involved drivers, respectively. For the Cox proportional hazard model, license class 1 acquisitor was found to increase the survival duration till the first traffic violation was made, while male, age of 21-24, age of 25-34, age of 45-54, and crash involved drivers were more likely to reduce the survival duration. CONCLUSIONS : Absolutely, traffic violation is closely related to traffic accidents and all of the drivers should keep the traffic regulations to enhance highway safety. The results of this study might provide some insights to construct safe road environments by controlling the factors that reduce the traffic violation duration of novice drivers.

In this paper, we try to explore basic factors that defines easy-to-learn programming language and easy-to-learn development environments for novice students who have not been exposed to computer programming language education. For these purpose, we investigate and analyze computer programming languages that are widely used in industrial environments, and present the summary and analyzed results. From the experimental results, most novice programmers understand computer programming languages in terms of procedural programming languages rather than in terms of functional programming languages or object oriented programming languages. Furthermore, we have found that, for effective education of basic level programming languages, factors of development environments are much more important than factors of programming paradigms that the computer programming languages are based on.

This study intends to develop a fixture planning module as a part of the planning system for cutting. The fixture module uses machine learning method to reuse previous failure results so that the system can reduce the repeated failures. Machine learning is one of efforts to incorporate human reasoning ability into a computerized system. A human expert designs better than a novice does because he has a wide experience in a specific area. This study implements the machine learning algorithm to have a wide experience in the fixture planning area as a human expert does. When the fixture planner finds a setup failure for the suggested operations by a process planner, it makes the process planner store its attributes and other information for the failed setup. Then the process planner applies the learned knowledge when it meets a similar case so that the planner can reduce possibility of setup failure. Also the system can teach a novice user by showing a failed setup with a modified setup.

Objective: The purpose of this study was to compare the joint movements and muscle activities of novices according to pedal type (flat, clip, and cleat pedal). Method: Nine novice male subjects (age: $24.4{\pm}1.9years$, height: $1.77{\pm}0.05m$, weight: $72.4{\pm}7.6kg$, shoe size: $267.20{\pm}7.50mm$) participated in 3-minute, 60-rpm cycle pedaling tests with the same load and cadence. Each of the subject's saddle height was determined by the $155^{\circ}$ knee flexion angle when the pedal crank was at the 6 o'clock position ($25^{\circ}$ knee angle method). The muscle activities of the vastus lateralis, tibialis anterior, biceps femoris, and gastrocnemius medialis were compared by using electromyography during 4 pedaling phases (phase 1: $330{\sim}30^{\circ}$, phase 2: $30{\sim}150^{\circ}$, phase 3: $150{\sim}210^{\circ}$, and phase 4: $210{\sim}330^{\circ}$). Results: The knee joint movement (range of motion) and maximum dorsiflexion angle of the ankle joint with the flat pedal were larger than those of the clip and cleat pedals. The maximum plantarflexion timing with the flat and clip pedals was faster than that of the flat pedal. Electromyography revealed that the vastus lateralis muscle activity with the flat pedal was greater than that with the clip and cleat pedals. Conclusion: With the clip and cleat pedals, the joint movements were limited but the muscle activities were more effective than that with the flat pedal. The novice cannot benefit from the clip and cleat pedals regardless of their pull-up pedaling advantage. Therefore, the novice should perform the skilled pulling-up pedaling exercise in order to benefit from the clip and cleat pedals in terms of pedaling performance.

To evaluate the suitability of UML (Unified Modelling Language) in terms of educating novice software engineers, we have conducted a survey study with 102 students who were enrolled in a mandatory course for sophomores in computer science and engineering department. The results indicate that UML 1) has high satisfaction rate among software novices as an education material, 2) improves computational thinking and problem-solving skills, and 3) increases the efficacy of learning when the education program is implemented in the order of UML, programming practice, and physical computing. This paper suggests the applicability of UML as a new education paradigm in software education.
