In this study, correlations between the rock mass permeability before and after grouting & injection volume and the parameters of Q system were investigated on a grouted rock mass tunnel corresponding to rock class 4 and 5 in terms of Q classification system. As a result, it appears that the lower the Q value is, the higher the before-grouting permeability becomes and the smaller the injection volume of grouting becomes. Also RQD and Jn are the most influencing factors to the permeability of rock mass and the injection volume of grouting. In addition, it turned out that it was very difficult to lower the permeability of rock mass smaller than $1.0{\times}10^{-8}$ m/sec with the ordinary portland cement grout.

현재의 영상 검색 시스템은 일반적으로 카테고리 검색 및 분류 검색으로 구성되어 있다. 일반적인 영상 데이터베이스 구축 및 현재의 검색 방법으로는 영상에 대한 재미요인을 분석하여 사용자에게 제공되지 않는다. 하지만 본 논문에서 제시하는 Q-방법론을 사용하여 영상을 분석하였다. Q-방법론에 의하여 분석된 영상은 영상 서버에 저장되며 영상 위치와 분석된 영상 디스크립션 및 재미요인은 데이터베이스에 구축하였다. 또한, 카테고리 검색 및 분류 검색에 대한 단점을 보강하기 위하여 키워드 검색시 색인 사전을 참조하여 온톨로지 검색에 대한 기능을 강화하였다.

The morphological characteristics of leaves, trichomes, and acorns in 8- to 11-year-old reciprocal hybrids of Quercus dentata and Q. serrata were investigated. The reciprocal hybrids had obovate to obovateelliptic leaves that were smaller than those of Q. dentata but similar to Q. serrata in their leaf size, obtuse leaf apex, narrow-tipped leaf base, and shape of small to intermediate-sized serrations. The ray length of stellate hairs was intermediate between those of the parents, and the hairs showed dense growth. Long single hairs are present among the stellate hairs on the abaxial side of the leaves. Therefore, the hybrids of Q. dentata and Q. serrata could be identified by the size and shape of leaves, shape of serrations, and type of leaf trichomes.

This report is to introduce an article to compare 3 kinds of methods as RMR, Q-system and RMi published in Tunnel and Tunnelling Technology 2003. As rock mass classification is applied to estimate the amount of the support as an empirical design method, an attempt has been made to evaluate the parameters for classifications and their variations by Professor Nilsen and his team in Norway. Representability and reproducibility in measuring the field parameters are discussed and sensitivity of rating values in the three methods is also analyzed in this research. Although some parameters have high variation in rating among the 5 observers, the rock mass class has been found to be quite similar.

암반 불연속면에 대한 조사는 국제 암반역학회(ISRM)에서 추천하는 조사법이 합리적으로 불연속면이 특성을 기재할 수 있는 방안이기 때문에 널리 적용되고 있다 그러나, 이 안에서는 조사결과를 공학적 의미가 있는 암반특성치로 변환하는 방안에 대한 언급이 없다. 본고에서는 지질기술자들이 불연속면조사시 주로 사용하는 ISRM 추천안인 제시한 조사항목에 토목기술자들이 주로 사용하는 RMR 혹은 Q-system 분류안의 정량적인 값을 적용할 수 있을 지를 검토하였다. 이에 대한 관련기술자들의 관심이 모여질 때 정량적인 인자에 기초한 ISRM 조사법에 부합되는 암반분류안의 구축도 가능하리라 생각된다.

In this study, we analysed the technology convergence of Internet of Things(IoT) by International Patent Classification(IPC) code analysis. 163 patent applications in Korea are the subjects of this study. We confirmed that the most representative IPC code combinations between Main and Sub categories are G06Q 50/24-G06Q 50/22(6 cases), H04L 29/02-H04L 12/28(4 cases), G06F 15/16-G06F 3/048(3 cases), G06F 15/16-G06F 9/44(3 cases), and G06Q 50/22-G06Q 50/24(3 cases). The field of Health Care business have been prepared 9 patent applications by technology convergence between 'Health Care(G06Q 50/22)' and 'Patient Record Management(G06Q 50/24)'. Finally we also concluded that the core IPC code are G06F 15/16, G06Q 50/22, G06Q 50/24, and H04L 12/28 by the technology convergence interconnections analysis of IoT patent applications.

This research was conducted to determine if the obtained serological data would reveal: (1) grouping among basic Quercus species, (2) the degree of correspondence within and among any detected grouping, and (3) the comparative value of new serological technique, "rocket immunoelectrophoresis". Overall quantitative and qualitative data indicate the genus Quercus is distantly separated from the Fagus. Within the Quercus, the subgenus Cyclobalanopsis is separable from the Lepidobalanus. But the elevation of the Cyclobalanopsis to the rank of a separate genus is not warranted. Antisera produced to the species belonging to Lepidobalanus gave strong reactions with other experimental species in the same subgenus. Particularly, Q. aliena, Q. donarium, and Q. serrata are tied up each other in terms of serological similarity. Rocket immunoelectrophoresis used in this systematic research proved to be a valuable new technique for systematic serology. To obtain the degree of protein similarity (serological correspondence) this technique was used in plant systematic research and determined by sum of total rocket heights. The rocket immunoelectrophoresis illustrated the measurement of individual immunoprecipitin systems identical or partly identical to those in the reference-reaction as quantitation of all available rocket heights.t heights.

This study used the Q-method to derive the structure of subjective opinions and perceptions of university students about the behavior of food delivery agency service provided by staff not directly employed in restaurants. For this purpose, the Q factor analysis was performed using the PC QUANL program for the Q-sort, which consists of a statement card, a P-sample, and a classification process. The results were classified into three types. The factor names were set as the first type (N = 7): efficiency seeking type, the second type (N = 19): benefit seeking type, and the third type [(N = 6): cost-effectiveness seeking type. The characteristics of each type are Type 1:Types that recognize aspects that are efficient for both consumers and restaurants, Type 2: Types of recognizing aspects of being benefited from speed, convenience and benefit, Type 3: Although it contributes to labor cost savings, it appears to recognize price and quality aspects in the initial market, which is burdened by consumers. The purpose of this study is to derive the problems of food delivery agency service business according to the three types and to provide strategic implications for the development direction and improvement plan.

본 논문에서는 국내 여러 지역에서 수행된 도로, 철도 및 기타 토목공사를 위한 설계과정에서 조사가 이루어진 현지조사와 시추코아 및 시추공을 대상으로 암반평가가 이루어진 자료들을 대상으로 암반분류방법간의 상관관계에 대해 조사하였다. 상관관계에 대한 해석은 암반분류에서 많이 사용되고 있는 RMR과 Q분류법간의 상관관계 그리고 RQD와 두 암반평가방법간의 관계에 대하여 암석성인별 분류 즉 화성암, 퇴적암 및 변성암별로 검토를 실시하였다. 전체적으로 분류방법의 상관관계는 좋게 나타나고 있다. 그리고 음파검층에 의한 탄성파 P파 속도와 RMR의 상관관계를 고찰하였는데, 이 두 요소간의 상관성은 비교적 양호하였으며 보다 신뢰성 있는 관계식을 유도하기 위한 노력이 필요하다.

The effect of conducted using Q research method, which is one of qualitative analysis methods that can approach in-depth and essential meaning of Spanish restaurant's perception of dining out consumers. The purpose of this study is to classify Spanish restaurant's perceptions of catering consumers by type, to find out the characteristics among them, and to suggest future improvement directions. An exploratory study was conducted using Q-methodology to analyze the subjective perceptions of restaurant customers in Spanish restaurants. To this end, the Q-sort, which consists of a statement card, a P-sample, and a classification process, was analyzed through Q factor analysis using the PC QUANL program. The results were classified into two types. Type 1 (N=10): Spanish restaurant preference, Type 2 (N=7): The name of the factor was set as the type of professionalism in Spanish restaurants. Each type was found to have different characteristics. Each subjective perception detected through this analysis can be used as basic data for various studies.
