항만의 공공서비스품질이 고객만족에 미치는 효과분석

이정호(Jeoung Ho Lee),최병대(Byung Dae Choi) 한국정부학회 2013 한국행정논집 Vol.25 No.3

항만 간 상호 경쟁이 치열해지면서 운영시설 등 하드웨어적인 측면이 경쟁우위에 중요한 영향을 주고 있지만, 이에 못지않게 항만물류와 관련된 소프트웨어 측면의 공공서비스 제공의 질적 향상도 항만의 경쟁력제고에 중요하다. 항만물류서비스의 직접적인 제공은 터미널운영사, 선사 등의 물류업체가 수행하지만, 공공기관(CIQ기관, 지방해양항만청, 해양경찰, 동·식물검역소 등 관련 정부조직과 지방자치단체)의 행정서비스가 미흡하면 항만물류 관련 공공서비스의 품질이 저하되는 결과를 초래하기 때문이다. 본 연구는 평택항을 이용하는 고객을 대상으로 항만물류를 처리함에 있어 공공서비스품질이 고객만족에 미치는 효과를 분석하였다. 분석결과 공공서비스품질이 신속하고 적극적인 서비스를 제공하거나, 공공기관의 유연한 대처, 공공기관 직원의 고객에 대한 이해나 배려가 높을 경우에 만족도가 높으며, 계속 이용할 의도가 있다고 분석되었다. 반면 공공시설이나 공간의 쾌적성, 최신시설과 장비구비가 전반적인 만족에는 영향을 주지만 계속이용에는 영향을 주지 않은 것으로 분석되었다. 따라서 항만당국은 항만의 경쟁력을 높이기 위해 하드웨어적인 측면뿐만 아니라 소프트웨어 측면인 공공서비스 품질의 향상도 함께 도모할 수 있는 종합적인 정책을 수립하여 실행하는 전략을 추진할 필요가 있다. As competition among ports continually increases, it is understood that well-maintained facilities are likely to receive more traffic, but the quality of a port’s customer service should be given equal consideration when searching for ways to increase competitiveness. Port services are supplied by various distribution companies, such as shipping companies, terminal servicing companies, and so on. However, these companies lack sufficient administrative oversight (from organizations such as the CIQ, Regional Maritime Affairs and Port Services, the Coast Guard, Animal and Plant Health Inspections, and other related entities), which results in a decrease of quality customer service at these ports. This study is an analysis of the relationship between customer satisfaction and perceived port quality, based on surveys taken by customers of Pyeong-taek Port in South Korea. Satisfaction levels were high when port services were prompt and courteous, flexible in handling various situations, and took the customer’s circumstances into consideration. As a result, the customers at these ports were far more likely to continue using the same ports, according to survey results. However, high satisfaction regarding the maintenance of the facilities, quality of amenities, and the use of the latest equipment had a minimal effect on overall satisfaction, and provided little indication as to whether the customer would continue to use the same ports in the future. As port authorities attempt to establish a strong foundation and create an effective plan to increase port competitiveness, the quality of the facilities should not be the only consideration; careful attention should be given to increasing the quality of port services and customer satisfaction, which will provide optimal results for increasing port activity.

Temporal changes in growth performances, chlorophyll contents, and tissue water relations for determining their physiological responses of five economic tree species subjected to chronic water and nutrition stresses were investigated with containerized seedlings grown in different soil moisture regimes and nutrition levels. Seedlings of Quercus acutissima, Q. variabilis, Q. mongolica, Q. serrata, and Fraxinus rhynchophylla were propagated in plastic pots(I.D. 16㎝×Depth 16㎝) for the experiments. The seedlings were subjected to two soil moisture regimes of dry and wet soils and two nutrition levels of fertilization with N+P+K and no fertilization through the growing season from May to September in a green house. For the purpose of analyzing their responses to the environmental stresses, seedling heights and root collar diameters, chlorophyll contents, and P-V curve parameters of the seedlings were measured in May, July, and September. The environmental stresses coming from moisture and nutrient deficits affected the growth performances of seedlings variously among species and among different growing periods, as well as between height and basal diameter growth of seedlings. The growth performances of Q. acutissima were influenced sensitively on the stresses, but those of Q. mongolica less influenced in comparison with other species. Chlorophyll contents were generally higher in Quercus spp. than F. rhynchophylla through the growing season. The chlorophyll contents changed by species and by treatment through the season within ranges of 0.14-1.96 ㎎/g dry wt. of chlorophyll a and within 0.16-1.79㎎/g dry wt. of chlorophyll b, respectively. But the contents seemed to be decreased gradually through the chronic environmental stresses and leaf senescence. The osmotic potential at full turgor(Ψπo) and turgor loss point(Ψπp) had temporarily declined up to 3 to bars from -7.0∼-12.4bars in May to -10.2∼-17.5bars in September and up to 5 to 6bars from -7.6∼-14.2 bars in May to -12.9∼-20.4bars in September, respectively, with some exceptions. The values of Ψπp were generally high in F. rhynchophylla in May and July, but high in Q. serrata in September. Relative water contents at turgor loss point(RWCp) were generally high in F. rhynchophylla, but the temporal changes of RWCp were quite and frequently different among species and among treatment.

Seasonal and diurnal changes of stomatal diffusive resistance(S.D.R.) and transpiration rate(T.R.) were investigated for determining the ecophysiological water relations of economic tree species subjected to chronic water stress or exogenous abscisic acid treatment. Four species of oaks including Quercus serrata, Q. mongolica. Q. acutissima, and Q. variabilis were used as the experimental materials and also Fraxinus rhynchophylla was studied together with oaks. Stomatal diffusive resistances were repeatedly measured on the containerized 1-0 year seedlings subjected to two kinds of soil moisture regime (wet and dry) in June, August, and September by LI-1600 Steady State Porometer of LI-Cor, Inc.. Exogenous abscisic acid (ABA) solutions of 0.5 mM and 0.05 mM in July and August, respectively, were absorbed into shoots cut from the containerized seedlings for determining their effects on stomatal behavior and transpiration. Most of measurements in stomatal diffusive resistance maintained about 5 s/㎝ in the morning after sunrise despite of different treatments. But the values fluctuated frequently to high level above 20 s/㎝ through the` afternoon until sunset in the seedlings subjected to dry soil moisture regime. Despite of various treatments and environmental conditions, stomatal diffusive resistances of Q. variabilis were more stable than those of Q. serrata or Q. acutissima. Their values of F. rhynchophylla changed more irregularly in comparison with those of oak species. Exogenous abscisic acid absorbed into shoots cut from seedlings increased stomatal diffusive resistance obviously in most of the species studied. The stomatal responses to abscisic acid treatment were more sensitive in July especially in Q, serrata than in Q. variabilis and Q. acutissima. But the effects of ABA treatment were presented more remarkably in Q. acutissima in August. The responses to abscisic acid were not certain in F. rhynchophylla because of their various fluctuation patterns.

The magnetization characteristics of a transformer or a nonlinear reactor is analyzed in this paper. The analytic expression for the dynamic hysteresis loop which is divided into the saturation part and the loss part is expressed using the four term polynominal approximation. The coefficients of this expression are determined from the rms saturation curve and no load loss. The energy expression associated with the dynamic hysteresis loop is modified by introducing the correction factor K. The validity of the proposed technique is verified by the experimental results.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.
