모형이 갖는 불확실성의 정량화나 매개변수의 최적화는 계산시간의 기하급수적인 증가를 가져온다. 계산시간의 효율성을 극대화할 수 있는 기법으로 최근 대체모형이 개발되었으며, 다양한 분야에서 적용되고 있다. 그러나 대체모형은 훈련된 데이터 공간에서 크게 벗어난 극한 사상를 정확하게 모의하기는 어려운 단점이 있다. 본 연구는 이와 같은 대체모형의 단점을 개선할 수 있는 새로운 PCK(polynomial chaos-krigging) 기법을 제시한다. PCK는 PCE(polynomial chaos expansion) 기법과 OK(ordinary krigging) 기법을 결합한 것이며, PCK의 효과는 기존의 PCE 및 OK 모형의 결과와 비교하여 입증하였다. 본 연구의 분석 결과는 다음과 같다. (1) PCK는 더 적은 수의 훈련 샘플만으로도 원래 모형을 더 정확하게 대체할 수 있다. (2) 원래 훈련 샘플보다 약 3배 더 큰 극한사상을 모의했을 때, PCE와 OK는 예측이 실패하였지만, PCK의 예측은 정확하였다. (3) 민감도 분석 결과 PCK의 매개변수 특성과 거동이 PCE 및 OK보다 원래 모형의 특성과 거동에 더 일치한다. 본 연구에서는 3개의 대체모형의 결과를 원래모형의 결과와 비교하였으며 그 적용성을 극한강우에 대해 검토하였다. 일반적으로 훈련 샘플의 범위와 비슷한 강우사상에 대해서는 모든 대체모형의 결과가 우수하였으나, 훈련 샘플의 범위에서 벗어난 극한 사상의 모의는 PCK만 적용이 가능하였다. 제안된 대체모형은 극한사상의 예측에 있어 기존 대체모형보다 매우 향상된 정확도를 제공함을 확인할 수 있었다.

Objectives This study is designed to examine the relationship between healthy state (完實無病) of Sasang constitution and pulse wave (脈波). Methods The subjects were 100 patients who were diagnosed with Sasang constitution and underwent pulse analyzer test. The status of urination, defecation, perspiration, and digestion was classified as good, intermediate, and poor. The power, depth, speed, and roughness of pulse waves (脈波) were analyzed. Results Patients with poor digestion had relatively powerless pulse wave (無力脈). Soeumin patients had a higher rate of poor digestion compared to other constitutions. Soyangin patients had a higher rate of poor perspiration compared to other constitutions. Soyangin with poor defecation had relatively choppy pulse wave (澁脈), and poor perspiraton had relatively slippery (滑脈). Soeumin patients with poor digestion had relatively powerless pulse wave (無力脈). Conclusions The pulse wave of poor healthy state (完實無病) is an expression of a pathological syndromes (病證) caused by lack of or damage to healthy energy (保命之主). It was concluded that the pulse analyzer can be used to evaluate healthy state (完實無病).

The purpose of this study is to help classifying Sasang Constitution through correlation with sound characteristic. This study was done it under the suppose that Sasang Constitution has correlation with sound spectrogram. The following result were obtained about correlation between sound spectrogram and Sasang Constitution by comparison and analysis 1. Soeumin answered his voice low tone, smooth and quiet in the survey. Soyangin answered his voice high, clear, fast and speaking random. Taeumin answered his voice low, thick and muddy. 2. Taeyangin was significantly slow compared with the others in the time of reading composition. Taeyangin was significantly slow compared with the others in Formant frequency 1. Taeyangin was significantly discriminated from Soeumin in Formant frequency 5. Taeyangin was significantly low compared with the others in Bandwidth 2. Soeumln was significantly low compared with Taeyangin in Pitch Maximum and Pitch Maximum-Pitch Minimum. Taeyangin was significantly high compared with the others in Energy mean. 3. In list of specification, the discrimination rate was higher than that by lists of 13 in the results of Multi-dimensional 4-class minimum-distance. The discrimination rate of three disposition except Soyangin was higher than that of four disposition in the results of One way ANOVA and Analysis of dis crimination in SPSS/PC+. In CART, the estimate rate of Sasang Constitution discrimination was higher than any other method. It is considered that there is a correlation between sound spectrogram and Sasang constitution according to the results. And method of Sasang constitution classification through sound spectrogram analysis can be one method as assistant for the objectification of Sasang constitution classification.

1. Background and Purpose : Sasang Constitutional medicine is baon dividing individuals' constitutions into four categories. Determination of an individual's constitution, however, can be different according to who he or she consults with since it depends solely on the examiner's own perception and methods. Currently, the use of self-reporting questionnaires is accepted as a general approach in clinical settings, but the results of different questionnaires tend to be inconsistent. In this study, we investigated how different the results of the questionnaires are and what the inter-questionnaires agreement is. 2. Method : 1595 peoples who volunteered our research from 1997 to 1999 and were evaluated disease free were asked to mark out three questionnaires: Sasang Pattern Identification Questionnaire, QSCC I and QSCCII(QSCC I was completed by 348 patients only). 3. Results and Conclusions : Three questionnaires above produced different results as excepted. In Sasang Pattern Identification Questionnaire, the Soeumin accounted for 55.9%. With the modified version of Sasang Pattern Identification Questionnaire, the Taeumin was the majoriy(39.1 %) and, QSCCII also showed similar results(34.8% of Taeumin). In contrast, the QSCC I revealed the majority consisted of the Soyangin (59.1 %). In terms of analysis on inter-questionnaire agreement, Sasang Pattern Identification Questionnaire and its modified version showed the highest agreement of 66.3, followed by 55.6% of QSCCII and the modified version from Sasang Pattern Identification Questionnaire. Therefore, we concluded that the ideal choice to determine an individual's constitution, as far as questionnaires go, is to take results from both the modified version from Sasang Pattern Identification Questionnaire and QSCCII. We found the use of QSCC I can be confusing to reach a satisfactory agreement.

The two schools which eventually came to form the "Northerners party" in the middle period of the Joseon dynasty, were Nam'myeong school and Hwadam school. Nam'myeong's philosophy, which emphasized the importance and merit of acting upon respect and righteousness(敬義), encouraged many people to organize righteous militias during the war with the Japanese in the 1590s, and when Jeong In-hong established himself as the leader of the Northerners party during the reign of King Gwang'hae-gun, the philosophy of the party and the school continued to thrive. Also, Hwadam's philosophy, which tried to understand Neo-Confucianism from a flexible point of view and demonstrated a level of openness toward it, had a considerable influence upon the Northerners school as well. It seems Nam'myeong Jo Shik and Hwadam Seo Gyeong-deok were the ones who ultimately enabled the Northerners party to be more active in their operations of the government and also to approach more freely toward the ideology of Neo-Confucianism. Prime examples of the party's stance and attitude, and also of the school's philosophy and perception of the world, were figures like Jeong In-hong and Heo Gyun from the 'Majority Northerners(大北) party,' and Kim Shin-guk and Nam I-gong from the 'Minority Northerners(小北) party.'Since the time of King Injo's ascension to the throne in 1623, the philosophical society of Joseon came to be occupied by schools who were deeply committed and dedicated to the teachings of Ju Hi and his Neo-Confucianism, such as the Twe'gye and Yulgok schools, and as a result the Northerners' philosophy was pushed away from its former formidable status. Their political philosophy was also partially responsible for their fall, as they believed only them were the ideal Confucian figures(君子黨), and never appreciated the stances of other political factions. In the middle of the 17th century, passing through a war with the Manchurian Qing dynasty as well, they further became a mere undercurrent. Yet their thinking and philosophy partially survived, as it managed to affect and influence the Southerner school scholars who were living in the vicinity of the capital in the mid and late 17th century, as well as the "Shilhak" scholars such as Yi Ik/李瀷 in the 18th century, on a certain level. The Northerners faction was a party and a school which led the political and philosophical societies of Joseon, alongside the Westerners and Southerners, in the middle period of the Joseon dynasty. Recently, studies of Jo Shik and Seo Gyeong-deok, figures who were the roots of the Northerners faction, and studies of how the Northerners' political philosophy was inherited to the following generations, have been published and announced. All these efforts will enrich future studies dealing with the political history and philosophical history of the middle and latter periods of the Joseon dynasty.

This study investigated the differences between annual maximum series and annual maximum independent rainfall event series with relatively short and long rainfall durations. Annual maximum independent rainfall events were selected by applying various IETDs and thresholds to the hourly rainfall data in Seoul for the duration from 1961 to 2010. Annual maximum independent rainfall event series decided were then compared with the conventional annual maximum series. Summarizing the results is as follows. First, the effect of IETD and threshold was not beyond the expected level. For example, as the IETD increases, the frequencies of independent rainfall events decreased similarly in their rate for both with short and long durations. However, as the threshold increases, the frequency of those with rather long durations decreased much higher. Second, The mean rainfall intensity of the independent rainfall events was found to remain constant regardless of their duration. This indicates that the annual maximum rainfall intensity could be found in a rainfall event with longer durations. Lastly, the difference between the annual maximum rainfall series and the annual maximum independent rainfall event series with rather short rainfall durations was found significantly large, which decreases with longer durations. This result indicates that the conventional data analysis method, especially for small basins with short concentration time, could lead an unrealistic design rainfall with little possibility of occurrence.

연구목적 : 사상의학(四象醫學)은 인간을 태양인(太陽人), 태음인(太陰人), 소양인(少陽人), 소음인(少陰人)으로 구분하여 동일한 병증에 대해서도 치료를 달리하는 의학이다. 즉 인간을 동일한 원리로 설명하는 것이 아니라 각 체질에 따른 차등성을 통해 각 체질 취약점의 보완을 추구하는 의학이다. 그러면, 무엇이 이러한 인간 구분의 단서가 되었으며 이것이 의학으로까지 적용되는 과정 즉, 사상의학의 성립 과정을 살펴 보는 것을 연구 목적으로 한다. 연구방법 : 동무(東武) 이제마(李濟馬)의 저술로 인정되는 "격치고(格致藁)", "동무유고(東武遺藁)", "동의수세보원(東醫壽世保元)"의 문헌적 자료와 각 편의 저술시기를 통해 동무(東武) 이제마(李濟馬)의 사고의 흐름과 변화를 통해 사상의학이 성립되는 과정을 살펴 보는 문헌적 조사방법을 이용하였다. 연구 결과 및 결론 : 이상의 결과를 통해 아래의 연구 결론을 구하였다. 1. 동무(東武)는 "맹자(孟子)"의 사부지심(四夫之心)을 근거로 인간을 심욕에 따라 비인(鄙人), 박인(薄人), 탐인(貪人), 나인(懦人)으로 구분하였고 인의예지의 사단을 장부에 배속하여 심욕을 몸에 적용하였다. 그러나 "격치고(格致藁)"의 비인(鄙人), 박인(薄人), 탐인(貪人), 나인(懦人)과 "동의수세보원(東醫壽世保元)"의 태소음양인(太少陰陽人)의 직접 연결은 동무 사고의 시간적 흐름을 고려하지 않은 것이며, 동무는 "동의수세보원(東醫壽世保元)" "사단론(四端論)"과 "확충론(擴充論)"을 통해 비박탐라인(鄙薄食懦人)의 심욕(心愁慾)과 태소음양인(太少陰陽人)의 정기(情氣)를 매개로 하여 비인(鄙人)은 태양인(太陽人), 탐인(貪人)은 태음인(太陰人), 박인(薄人)은 소양인(少陽人), 나인(懦人)은 소음인(少陰人)으로 설명함을 확인할 수 있었다. 2. "격치고(格致藁)" "독행편(獨行篇)"과 저술 연도가 동일한 "동무유고(東武遺藁) 교자평생함(敎子平生箴)"을 통해 의학적 사고의 성립을 살펴보면, 동무(東武)의 차등적 장리(臟理)는 희노애락의 성정(性情) 구분이 장리(臟理)의 차이로 발전한 것이 아니라 장부(臟腑) 강약(强弱)에 대한 인식이 선행되고 이를 희노애락(喜怒哀樂)으로 설명하였으며, 또한 "동의수세보원(東醫壽世保元)"의 장부(臟腑) 대소(大小)는 강약(强弱)에 근거한 개념임을 알 수 있었다. 3. 사상의학(四象醫學)의 의학적 설명 도구는 희노애락(喜怒哀樂)이다. 희노애락은 비박탐라(鄙薄貪懦)와는 달리 선악(善惡)의 가치 판단이 들어있지 않으면서 기의 승강을 나타낼 수 있는 중용적 설명 도구로 동무가 의학을 설명하기 위한 최선의 도구였다. 사상의학(四象醫學)에서의 희노애락(喜怒哀樂)은 증치의학(證治醫學)의 음양오행(陰陽五行)의 역할과 같은 것이다. 4. 희노애락(喜怒哀樂)은 "동의수세보원(東醫壽世保元)"에서 성(性), 정(情), 기(氣)로 설명되는데 희노애락의 성(性)과 정(情)은 장부 대소를 설명하는 근거로 체질마다 다른 장국 형성을 가능하게 하고 또한 각기 표기(表氣)와 리기(裏氣)를 손상(損傷)하는 것으로 설명되었다. 희노애락(喜怒哀樂)의 기(氣)는 기(氣)의 승강(升降)을 설명하는 근거로 애기(哀氣)와 노기(怒氣)는 양(陽)으로 직승(直升)과 횡승(橫升)하고 희기(喜氣)와 락기(樂氣)는 음(陰)으로 방강(放降)과 함강(陷降)한다. 이러한 희노애락은 순동역동(順動逆動)의 특성과 상성상자(相成相資)의 특성을 지니는데 희노애락(喜怒哀樂)의 상성상자(相成相資)는 사상의학 고유 개념으로 사상인병증론(四象人病證論)에서 언급하고 있는 성정(性情)과 심욕(心慾)의 편급까지 영향을 미치는 중요한 단서이다.

This study finds aesthetic elements and examines their aesthetic sense focusing on the melody of the piri in the completed Jongmyojeryeak with various ideational backgrounds from the views different from the aesthetic sense of Jongmyojeryeak that has been conducted so far. Jongmyojeryeak is to hold a memorial service at the place where the godship of the line of kings and queens in Joseon is set. It is the crystal of Confucian memorial ritual and representative cultural heritage of ancestral ritual culture and is designated as No 1 of national chief, intangible cultural heritage in 1964. Also, on May 18th, 2001, it was registered first in Korea as 'Masterpieces of the Oral and Intangible Heritage of Humanity' designated by UNESCO and was recognized of its superiority. It is not only a representative cultural heritage of ancestral ritual culture having fate with Joseon Dynasty for a long period but also has been recognized as the essence of our music compiling the holistic beauty of artistic forms according to music, songs, and dance created by our ancestors. Also, it has as its background the traditional thoughts including the Confucian thought as well as Yeak thought, Yin-Yang School, Samjae thought (三才思想), and Palgoe thought (八卦思想). This Jongmyojeryeak internalizes landscape beauty, Yojang beauty, natural beauty, magnificent beauty, and harmonious beauty. Landscape beauty can be found in Huimun and Jeonpyehuimun. Yojang beauty is the figure that is only shown in Jeongdaeup. Natural beauty is the skilled performance technique shown in the melody of variations and is connected to natural creation. It is well shown in Huimun and Jeonpyehuimun. Magnificent beauty is well shown in the melody of Botaepyeong movement. And harmonious beauty is the harmonization of dischord in Jongmyojeryeak and is well shown in Jeongdaeup's Somu distinctively showing its aesthetic sense from the view of natural, harmonious beauty in its music.
