In the field of sCIence education, there is a tendency to introduce history of science into school lessons as a way to the effective teaching of science and a new direction of science education. This study aims at the effective way of correcting the misconceptions related to falling movement by investigating the development stages of scientific conceptions through lessons on history of science. To achieve this object, with use of "The inquiry and answer method" the misconceptions of students' on the weight and speed of falling matter, falling movement in vacuum, direction of motion and force direction, change in velocity and force in the gravity field have been investigated before the lesson has been performed. The traditional model of lesson(TL) and the model based on the science history(SHL) have been developed and applied to misconceptions mentioned above. The results of · the two models have been compared and analyzed to find out the effective way to overcome the misconceptions. Data were collected from 128 high school students in first and second grades. The results of this study are as follows, First, students have following misconceptions as follows, ① The heavier an object is, the faster it falls down. ② Gravity has nq effect on the motion in the vacuum, ③ Object moves in the same direction of force. ④ Force is in proportional to the speed of an object. ⑤ Force is transferred to the object form the applier and remains in the object. ⑥ Object needs a lasting force to maintain movement. ⑦ No force is being applied to an object at rest. Seconds, misconceptions of the students are very similar to those appeared on the development stages of concepts in the history of science. Third, SHL is much more effective than TL for the positive change In misconceptions about the falling movement. That is, in the rate of change In positive conception on each item, the former is higher than the latter by 4.5% to 45.1%. Fourth, many ~tudents responded informally . thi,l.t the{'fe,lt much . interested and excited to find out that the thoughts similar to their own also discussed on the developmental stage of science history. Fifth, lesson on science history is rather effective in correcting the misconceptions by letting students to realize how their opinions on particular concepts were criticized and revised in the history of science. In SHL students compare their concepts . with those appeared , qn the development stage of history of science. The concepts in the history of science may be similar or dissimilar with the students' own concepts. Through the comparing activities students correct their misconceptions. Therefore, SHL is more effective in correcting the misconceptions than TL without those activities. Sixth, the science education can be carried out more effectively when students take part in the lesson actively and eagerly. SHL reflects more positively the students' activities than the teacher- oriented TL does, resulting in effective change in the misconceptions of students.

Purpose: The hepatic resection is the gold-standard treatment for patients with colorectal-cancer liver metastases (CLM). This study aimed to identify prognostic factors in patients with synchronous CLM who underwent a surgical curative (R0) resection with respect to the number of metastatic nodules. Methods: Of 1,261 CLM patients treated between January 1991 and December 2010, 339 who underwent a R0 resection for synchronous CLM were included in this retrospective analysis. Patients were grouped according to the number of CLM nodules: 1–2 CLM nodules, n = 272 (group 1) and 3–8 CLM nodules, n = 67 (group 2). Results: The 5-year progression-free survival (PFS) rate in group 1was better than that in group 2 (P = 0.020). The multivariate analysis identified lymph-node metastasis (N2), lymphovascular invasion (LVI), and three or more CLM nodules as independent poor prognostic factors for PFS in all patients and lymph-node metastasis (N2) and LVI as independent poor prognostic factors for patients in group 1. No independent prognostic factors were identified for patients in group 2. CLM treatment method and neoadjuvant chemotherapy were not associated with survival. Conclusion: Three or more metastatic nodules, lymph-node metastasis (N2), and LVI were independent poor prognostic factors for PFS in patients with synchronous CLM who underwent a R0 resection. The latter 2 factors were also independent prognostic factors for PFS in patients with less than 3 CLM nodules; however, in patients with three or more CLM nodules, the prognosis for PFS may be related only to liver metastasis.

곽계환,장기웅 圓光大學校 1996 論文集 Vol.31 No.2

본 연구는 속빈 연속 슬래브교의 실제거동에 근접하는 합리적인 격자해석모델(grillage analysis model)을 구성하고 이방성(orthotropic)과 등방성(isotropic)에 대한 거동특성을 비교, 분석함과 아울러 사하중, 활하중 및 온도하중 등의 설계하중에 대해 구조해석방법을 제시하고자 한다. 이를 위해 본 연구에서는 속빈 연속 슬래브교의 구조거동을 잘 표현함과 동시에 해석하는데 시간과 노력이 비교적 적게 드는 격자망을 구성하기 위해 교축방향과 교축직각방향의 부재수가 각기 다른 세가지의 격자모델에 대해 해석을 실시하고, 각각의 모델에 대해 이방성과 등방성에 단면상수를 적용하여 그 결과 비교 분석한다. 그리고 실제교량에 대해 현장에서의 정적 및 동적재하시험을 실시한 후 그 시험결과와 해석결과를 비교함으로써 격자모델의 타당성을 입증하고 합리적인 격자망을 제시한다. The aim this paper is to present a reasonable grillage model for approximately analysis actual behavior of a voided slab bridge and to compare two geometrical properties of isotropic and orthotropic in the bridge deck. In this study, three models were prepared and analyzed to form the grillage mesh relevant to the voided slab continuous bridge. The grillage mesh was consisted of the longitudinal beams and the transverse beams equivalent to the prototype slab stiffness. By applying the different section properties of isotropic and orthotropic slab to each model, the difference of the resultant force was compared and studied. The loading tests in field were carried out to evaluate the static and dynamic behavior of a existing voided slab bridge. The results from the tests have been compared with it analyzed with the grillage model. Finally, it is concluded that the total number of logitudinal members should be less B(slab width)/1.5, spacing of transverse members should be about L(span length)/2.5.

도선의 풍수지리사상 연구

조수동,장기웅 새한철학회 2001 哲學論叢 Vol.23 No.1

풍수지리설은 우리 민중의 정신사의 한 면을 차지하고 있는 중요한 사상이며 그 중심인물은 도선이다. 고려 왕조의 도선 현창 운동은 결국 왕조 성립의 정당성을 세우려는 의도에서 나온 것이라 할 수 있다. 풍수지리는 땅과 인간과의 관계 즉 그 땅에 의지해서 살고 있는 인간의 길흉화복을 설명하는 이론인데, 그 철학적 근거는 易과 陰陽五行사상이다. 풍수지리에서는 땅의 모양새가 그 곳에 사는 사람들의 운명을 결정한다고 보고 있기 때문에 地勢가 바뀌지 않은 한 인간의 운명은 바뀌지 않는다고 한다. 풍수지리설이 민중의 마음속에 깊이 파고 들 수 있었던 것은 사회 정치적 혼란으로 인한 민중들의 삶의 불안 때문이라 보여지며, 특히 국가 사회 혼란기에 중국에서 들어온 도참설과 연관되어 더욱 발전된 것으로 보인다. 도참설의 근거는 천인감응설이다. 도선은 풍수지리설을 세상을 구제하는 가르침이라 하고, 이것을 도참설과 결부시켜 산수의 순역의 형세를 보아 역처에 비보사탑의 설립을 주장하고 있다. 고려시대에는 주로 왕도의 흥망성쇠와 관련된 양기풍수가 발전했다. 그리고 조선시대 초기에도 도읍지 건설을 위한 양기풍수사상이 성행하였지만, 이후 유교의 가족주의와 효 사상을 기반으로 한 음택풍수가 크게 성행하였다. Punsu chiri theory is capital thought that function a role in spiritual history of our people and th leading figure of it is Doson. The restoration of Doson in Koryo Dynasty has purpose to set up legitimation of organization of Dynasty. Punsu chiri theory elucidate human-relation, namely the fortune and misfortune. Human-being on which lives by philosophical foundation of Yin Yang and the five Eliments, In Punsu chiri theory, man think the destiny of human-being can't vary as long as the shape of site not vary because man think the destiny of human-being deponds on the shape of land. It seems that Punsu chiri theory can affect popular mind because of unrest popular life by socio-political disturb. Especially, Punsu chiri theory was developed with Tocham theory inflowed from China. The main concept of Docham theory grounded in the thought of response between Heaven and Man. Doson claims that Punsu chiri theory is doctrine of relief of The world, He combine it with Tocham theory and he claimed the establishment of The Bibo temple pagoda by evaluating the shape of good and bad of landscape. In Koryo, mainly Yangki Pungsu, associated with the rise and fall of dynasty, was developed. And Yangki Pungsu also widespread in the early years of Yi-dynasty to construct capital city, but thereafter Yintack Pungsu was more widespreaded on the nepotism and the thought of filial piety.
