Follow-up process consists of two steps. First, it monitors whether project proponents comply with reviews made by KEI. The second steps is to survey environmental impacts during and after implementation of the proposed action. The follow-up requires the proper participation of stakeholders: project proponents, compliance monitors, impact monitors, and environmental agencies approving and reviewing said projects. Currently, follow-up process does not work well because each stakeholder does not play his proper role for various reasons such as mutual distrust among stakeholders and problems associated with institutional settings. This study intends to improve effectiveness of follow-up process and, ultimately, to improve quality of EIA in Korea by devising a follow-up system that delineates clear roles and build a strong network among stakeholders. In order to do so, the study identifies current problems associated with follow-up process and examines basic concepts and procedures involved in it. Secondly, it analyzes relational dynamics among stakeholders to identify what's behind the current mutual distrust. Third, it proposes a way to delineate clear roles to each stakeholder so that follow-up process runs efficient as an organic network.

This study was conducted to determine whether follow-up management is carried out continuously following CQI activity and to analyze the factors behind the success and failure of follow-up management. Past presentations from 1994-1999 of CQI coordinators and lecturers from various institutions who presented at The Korean Society of Quality Assurance in Health Care(KoSQA) on the conditions of follow-up management in each institution were analyzed. The results of this study were as follows; Since the number of subjects on CQI increased each year at symposiums, this has expanded to all medical institutions. Although medical institutions usually conduct 11-20 subjects on CQI per year, there were many such occasions where more than 31 subjects were conducted. Moreover, institutions with less than 800 beds have come up with more projects than those with more than 800 beds, thus 23.3% of these institutions had at least 1 person involved in 4 projects. This had created an overload of responsibilities for specific persons' involvement, prompting them to incline toward formalities in their work rather than substantial activities. Among the projects presented at the symposiums, 51.7% demonstrated that follow-up management could be carried out. In particular, 55.3% of the projects from provincial regions could carry out follow-up management compared to 48.8% in Seoul. Moreover, it was demonstrated that 80% of the projects from institutions with 600-799 beds carried out follow-up management most effectively. With regards to previous presentations, the older they were, it was found that follow-up management could not be effectively carried out. Some institutions that responded that follow-up management was carried out effectively in their institutions were found to have conducted follow-up management without any inspection strategies or the appropriate tools. CQI activities were executed and terminated with no consistency and team members had no real concern for it. The most important factors that contribute to an effective follow-up management are the need for concern and interest from the directors of the hospitals, from the relevant departments and team members in addition to the role of the supervising department, follow-up management through management of target goals, consistency in tasks along with communication between all team members. The biggest problems were perceived to be overload of work due to accumulation of proposed projects in addition to lack of awareness pertaining to follow-up management. CQI is beneficial for all staff for the improvement of the mind and business administration and thus it is believed to be desirable. To carry out follow-up management effectively, leadership, analysis and application of information, follow-up management and planning, as well as quality management are perceived to be essential, on the other hand, the results showed a significant difference. To prevent CQI activities from becoming just an activity, the basic system should be reconstructed and augmented based on the problems derived from the results of this study. Moreover, we hope this study will be used as reference material that would encourage the administration of follow-up management after CQI activities in most hospitals. Furthermore, various studies on follow-up management should be conducted for CQI activities in the future.

One of the main purposes of the marine gyrocompass follow-up system is to preserve the sensitive part from the wandering error due to the frictional or torsional torque around the vertical axis. This error can be diminished through the rapid follow-up action, which minimizes the relative azimuthal angular displacement between the sensitive and follow-up parts and shortens the duration of the same displacement. But an excessive rapidity of the follow-up action would result in a sustained oscillation to the system. Therefore, to design a new type of the follow-up system, the theoretical annlysis of the problems concerned should be studied systematically by introducing the control theory. This paper suggest a concrete procedure for the optimal adjustment of the gyrocompass follow-up system, utilizing the mathematic model and the stability informations formerly investiaged by the author. For theoptimal determination of the adjustable paramfter K, the performance index(P.I.), ITSE(Intergral of the Time multiplied by the Squared Error) is proposed, namely, P.I. = $\int_{0}^{\infty} t \cdot e^{2}(t)dt$ where t is time and e(t) means control error. Then, the optimal parameter minimizing the performance index is calculated by means of Parseval's theorem and numerical computation, and the validity of the obtained optimal value of the parameter Ka is examined and confirmed through the simulations and experiments. By using, the proposed method, the optimal adjustment can be performed deterministically. But, this can not be expected in the conventional frequency domain analysis. While the Mps of the original system vary to the extent of from 0.98 to 46.27, Mp of the optimal system is evaluated as 1.1 which satisfies the generally accepted frequency domain specification.

As a basic study for enhancing the sensitivity of the follow-up system of the marine gyrocompass, the geometric characteristics of the deflection sensor were investigated and the theoretical model of it was formulated. The output signal voltage of the deflection sensor was esamined by changing the attitude of gyrosphere against follow-up container. The characteristics of the output are found to be indentical with those of the distance difference versus the relative azimuthal deflection of the gyrosphere against the follow up container. On the base of the theoretical model, some useful points for the design of the deflection sensor are suggested as following : 1. When the difference between semidiamter of gyrophere and that of the follow-up container decreases, the sensitivity of deflection sensor increases. 2. If the semidiameter difference of two spheres is constant, the sensitivity of deflection sensor is proportional to the magnitude of the semidiamter of each sphere. 3. The farther the gyrosphere is deviated from the center of follow-up container, the higher the sensitivity of deflection sensor is. 4. It is recommendable that the value of the datum deflection of the electrodes on the gyrosphere should be within the range between $4^{\circ}$ and $16^{\circ}$deviated from north-south line.

International Organization for Standardization has recently published ISO 9001:2008 which is the basic requirements for a quality management system that an organization must fulfil to demonstrate its ability to consistently provide products that enhance customer satisfaction and meet applicable statutory and regulatory requirements. Not many empirical researches based on ISO 9001:2008 have been done up until now. In this article we outline transitional features for ISO 9000 quality management system (QMS) since its first publication in 1987. In order to effectively maintain ISO 9001:2008 QMS certification and continuously enhance quality management activities, we perform statistical analysis for the minor nonconformity data generated from follow-up audits for subcontractors of shipbuilding industry based on ISO 9001:2008 requirements. A Kruskal-Wallis test is used to show relationships between the minor nonconformity data and three classification criteria: the type of business, the size of business, and the number of follow-up audits.

Here we describe the neurodevelopmental outcomes of very low birth weight (VLBW) infants (birth weight ≤1,500 g) at 3 years of age in the Neonatal Research Network of Japan (NRNJ) database in the past decade and review the methodological issues identified in follow-up studies. The follow-up protocol for children at 3 years of chronological age in the NRNJ consists of physical and comprehensive neurodevelopmental assessments in each participating center. Neurodevelopmental impairment (NDI)-moderate to severe neurological disability-is defined as cerebral palsy (CP) with a Gross Motor Function Classification System score ≥2, visual impairment such as uni- or bilateral blindness, hearing impairment requiring hearing amplification, or cognitive impairment with a developmental quotient (DQ) of Kyoto Scale of Psychological Development score <70 or judgment as delayed by pediatricians. We used death or NDI as an unfavorable outcome in all study subjects and NDI in survivors using number of assessed infants as the denominator. Follow-up data were collected from 49% of survivors in the database. Infants with follow-up data had lower birth weights and were of younger gestational age than those without follow-up data. Mortality rates of 40,728 VLBW infants born between 2003 and 2012 were 8.2% before discharge and 0.7% after discharge. The impairment rates in the assessed infants were 7.1% for CP, 1.8% for blindness, 0.9% for hearing impairment, 15.9% for a DQ <70, and 19.1% for NDI. The mortality or NDI rate in all study subjects, including infants without follow-up data, was 17.4%, while that in the subjects with outcome data was 32.5%. The NRNJ follow-up study results suggested that children born with a VLBW remained at high risk of NDI in early childhood. It is important to establish a network follow-up protocol and complete assessments with fewer dropouts to enable clarification of the outcomes of registered infants.

Purpose: This is a report on the outcomes associated with a consecutive series of 1,000 cementless hip arthroplasties utilizing the $Bencox^{(R)}$ hip stem-the first Korean-developed hip prosthesis. Materials and Methods: A consecutive series of 1,000 hip arthroplasties using the $Bencox^{(R)}$ hip stem were analyzed, starting from its initial release (September 2006) until June 2014. Patients in this consecutive series underwent surgery for fractures (n=552), arthritis (n=155), avascular necrosis (n=209), and revisions (n=84). Of these 1,000 cases, patients with a minimum follow-up of at least 1 year (n=616) were retrospectively analyzed for radiographic and clinical outcomes (i.e., Harris hip score). The stability of the prosthesis was evaluated by examining subsidence. Results: During the follow-up period (mean follow-up period of 54.8 months), there were 2 cases requiring revision of the femoral stem-both were caused by periprosthetic fractures and neither involved stem loosening. The mean Harris hip score during follow-up was 95.5. Bone ongrowth occurred in 95% of patients; no cases of subsidence or aseptic loosening of the stem were detected, and no cases of postoperative complications such as ceramic breakage were observed. Conclusion: Clinical and radiographic evaluations of hip arthroplasty using the $Bencox^{(R)}$ hip stem revealed excellent outcomes with an average of 54.8 month follow-up in a consecutive series of 1,000 cases.
