This study was carried out to obtain the basic data for selecting the applicable crops in reclaimed land during desalinization period. A pot experiment was conducted with 5 different electrical conductivities of the saturated extracts (ECe 1, 3, 9, 14, and 16 dS·m^(-1)) of soils taken from the Dae-Ho reclaimed tidal lands. Eight crops (Chinese cabbage, radish, tomato, red pepper, buckwheat, soybean, sesame, and green perilla) were grown for 37days. Plant height and number of leaves were surveyed on 2 and 4 weeks after seeding, and on harvest time (5 weeks). After harvest, dry weights of harvested crops were measured and soil chemical properties were analyzed. Emergence rates of crops were comparatively high except sesame. For sesame, there was no emergence at ECe over 3 dS·m^(-1). Growth and dry weight decreased significantly as increasing ECe. The ECe which decreased 50% of dry weight index were 14.2 dS·m^(-1) for radish, 11.4 dS·m^(-1) for Chinese cabbage, 10.2 dS·m^(-1) for tomato for red pepper, 8.9 dS·m^(-1) for buckwheat and green perilla, 8.6 dS·m^(-1) for soybean, and 8.9 dS·m^(-1) for tomato. At higher ECe that start the growth inhibition, increasing 1 dS·m^(-1) in ECe, 7.7, 6.5, 5.9, 5.6, 5.2, and 4.9% of dry weight decreased for buckwheat, green perilla, Chinese cabbage, radish, soybean, and tomato (red pepper), respectively. The critical value of ECe for crop survival except sesame was 15.4~23.1 dS·m^(-1).

Tracheobronchopathia osteoplastica is a rare disorder of unknown cause characterized by the projection of numerous bony or cartilaginous submucosal nodules into the tracheobronchial lumen with sparing of the posterior membranous portion of tracheobronchial tree. In the past, most of the cases were diagnosed as secondary finding at autopsy. Nowaday, the key component of the evaluation is flexible fiberoptic laryngoscopy and bronchoscopy, which typically demonstrates irregular spicules of subrnucosal bone and cartilage projecting into the tracheobronchial lumen and causing various degrees of airway obstruction. A 45 years old man was visited Sunchon St. Carollo hospital due to discomfort on throat. We saw several nodules just below vocal cord via laryngoscope. The computed tomography revealed multiple small calcified nqdules on trachea and both main bronchi. Pathologic finding of bronchoscopic biopsy showed abnormal proliferation of bony and cartilagious nodules in the tracheal submucosa. These fingdings were consistent with tracheobronchopathia osteoplastica. We report here on a case of tracheobronchopathia osteoplastica with review of literature.

홍승아,이미영 울산과학대학 1999 연구논문집 Vol.26 No.1

이글은 여성의 실업문제에 주목하여, 특히 실직 여성가장에 대하여 살펴보고자 한다. 이를 위해 첫째, 여성실업의 문제를 바라보는 시각들을 정리해 보고, 둘째, 통계자료를 통하여 실업실태를 개관해 보고, 세째, 울산지역의 실직 여성가장의 현황에 대하여 살펴본 후에, 마지막으로 이를 토대로 실직 여성가장에 대한 제언을 제시해 보고자 한다. 실직 여성가장에 대한 실태조사는 설문조사 및 면접조사를 통하여 살펴보았으며 조사결과는 다음과 같다. 실직 여성가장은 최근 1년 이내에 실직을 경험한 경우가 53.9%로 나타났으며, 특히 이들이 가장 필요하다고 생각하는 것은 일자리와 생계대책으로(80.8%) 나타나, 당장의 생계와 재취업에의 열망이 가장 큰 것으로 조사되었다. 따라서 실직 여성가장에게 일자리를 창출할 수 있는 적극적인 여성정책이 요구된다. This paper empirically examines the status of the unemployed female- headed family in Ulsan area. This study uses data collected from usable 182 cases among 200 collected data who responded to the questionnaires. This study showed that the unemployed female-headed family are situated in the very vulnerable position. And the very things they really wanted are "job hunting" and the urgent subsistence maintenance. And they also wanted governmental financial assistance, social support system at a moderate level. Therefore they need a "positive and inclusive" women policy which can create job place for the them.

This study was undertaken to find out factors predicting the results of the nonoperative treatment for lumbar intervertebral disc. Inclusion criteria were as follows : 1) The patient was comfirmed lumbar intervertebral disc in the computed tomography and/or magnetic resonance imaging by a radiologist's reading. 2) The patient had undergone an intensive physical rehabilitation program for at least four weeks. 3) The patient should have no other medical problems which delayed the period of treatment or aggravated the symptom. 4) The patient should have no previous lumbar surgery. All patients were assessed by the low back pain protocol which was composed of symptom, clinical sign and activities of daily living scales before and after the treatment. Changes in LBP score were evaluated by age, sex, occupation, duration of the symptom, means of the payment, marital status, education period, radiologic finding, self assessement and MMPI. In conclusion, poor result could be predicted after the nonoperative treatment in the patient groups of : 1) duration of the symptom over 6 months, 2) hospital payment by others, and 3) high score in the Hypochondriasis and Hysteria scales in MMPI.

성찰적 실천의 관점에 비추어 본 수업설계자의 전문성 개발방안 탐색 : Focused Reflection in Action and on Action

이승희,유영만 한국교육정보방송학회 2002 교육정보미디어연구 Vol.8 No.2

수업설계는 역동적이고 복잡하면서도 고도의 전문성이 요구되는 지적 활동이다. 그러나 수업설계자의 전문성을 개발하는 전통적 방식은 기술적 합리성과 도구적 관심에 바탕을 두고 수업설계에 대한 개념적 지식과 스킬을 습득하는데 많은 비중을 두어왔다. 이러한 방식으로는 수업설계자가 수업설계 능력을 향상시키는 것이 쉽지 않다. 나아가 실천적 지침을 주지 못하는 수업설계 매뉴얼과 이를 기반으로 개발된 교육 프로그램은 현장의 교육요구를 해결하거나 수행문제 개선에 크게 기여하기 어렵다. 본 연구는 수업설계자의 핵심역량 중의 하나인 수업설계자의 능력을 향상시키는 기존의 방안에 한계가 있음을 지적하고, 성찰적 실천의 관점에서 기존의 문제점을 해결하는 방안을 모색해 보고자 하였다. 이를 위해 (1)실천적 지식구성, (2)상황구속성, (3)협력적 학습이라는 수업설계 활동의 본질과 수업설계에 대한 선행연구들을 토대로, 수업설계자의 전문성 개발의 원칙(실제성, 대화, 협력 및 다의적 의미구성)을 도출하였다. 또한, 성찰적 실천의 관점에 비추어 본 수업설계자의 전문성 개발 방안으로 학습 사이클 - (비)형상화된 문제상황 탐색, 문제상황 가시화, 문제해결을 위한 활동표현, 성찰적 실행 및 순환 반복적 개선-을 적용할 것을 제안하였다. Instructional designing activities can be said as the highly complicated but dynamic profession. The traditional ways of developing competencies for instructional designers have rooted from assumption of technical rationality and technical interest in which all the related process, knowledge and skills needed for designing instructional programs have been acquired followed by prescribed and systematic methods. Those assumptions have the tendency to lead a variety of learning programs in the real fields, therefore, have come to unfruitful training for activity, not training for impact. What matters most for instructional designers lies on the reflective thinking or reflective practice with which instructional designers or field practitioners can diversely understand problem situations and explore possible solutions to meet fields learning needs. The model of instructional systems designing activities for educating instructional designers should be come to an approach in the same manner. Instructional designing activities themselves should be redefined as knowledge constructing process, situation-specific activity as well as collaborative inquiry experiences with partner groups involved in a particular project. This paper suggests an alternative professional development for instructional designers in terms of reflective practice perspectives, and drew out some implications of five major learning principles and a feasible circular instructional designing process(exploring ill-structured problematic situation, visualizing problems, expressing problem solving activities, implementing keen observation and finally recursive revising).

The explosive growth of the internet traffic has imposed tremendous stress on routers, particularly, in the core network. Today's IP services reflect the unpredictable and undifferentiated packet loss and jitter characteristics of traditional best-effort routers. For above requirements, it is required not only the high-speed transmission of the packet, but the new routing function, the guarantees of QoS and bandwidth, the supports of user-requested services MPLS is proposed by the IETF and many other research institute as the solutions for this problem. In this paper, analyze performance of QoS Model applied RSVP over DiffServ to MPLS network. this model is each RSVP applied access network and DiffServ applied core network. In Result, It is amiss that basis MPLS net uses to core network because the average packet loss rate and average delay time are increased if traffic increases. Experiment result was seldom difference in case of network that apply each RSVP, DiffServ, RSVP over DiffServ. RSVP over DiffServs case packet loss rate and delay time were low than DiffServ and the packet loss rate is high because comparing than RSVP but delay time was very low.

Fire-damaged structural behavior of high strength reinforced concrete columns mostly depends on duration of heating time, geometrical shape of a section, constituent material properties, loading conditions and moisture content. Unlike beam element, all boundaries of a column suffer from heat-induced damages and this requires real-size experiments be conducted in order for accurate assess of the fire-damaged structural behavior of columns. Ten real-sized high strength concrete columns with different parameters are exposed to fire for three different time intervals in this research. Observations are made for the effect of these parameters on the degree of spalling, axial expansion and contraction, member buckling, failure based on ISO standard in addition to data of heat propagation in a section during the heating.
