  • The purpose of this qualitative study was to identify high school students' conceptual differentiation patterns on human digestion system. The subjects were 124 high school students and this group was guided to independently construct concept maps. Among them, 19 were selected for an in-depth interview and a short test. The concept maps, interview transcripts and the results of short-test were analyzed to identify conceptual differentiation patterns. The results were as follows. Mainly three distinct conceptual differentiation patterns were identified. The first pattern can be named as an 'Free-flow type'. The group belongs to this pattern expressed numerous examples than meaningful concepts with unclear understanding of hierarchial relation between each concepts. Also, this group had difficulties in grasp interrelations of different concepts. The second pattern can be identified as 'Sequence type'. This group constructed concept maps by featuring conceptual sequence. The group applied meaningful learning, yet assembled concept maps primarily according to sequence of learning and exhibited less organized concept maps than hierarchial type. The third pattern can be named as 'Hierarchial type'. All students elaborated concept maps after lessons. The sequence type changed hierarchial type or sequence mixed with hierarchial type but free-flow type was hardly changed.

  • In order to cloning of PPO gene as a melanin formation related genes involved in hardening and pigmentation of insect integument or wing, we cloned cDNA and analyzed the sequence of PPO gene of H. axyridis. PPO2 primer were designed based on the sequences of PPO genes of Tribolium castaneum and Drosophila melanogaster, and then plasmid DNA were cloned from PCR products obtained from different two color patterns. When the plasmid DNA band pattern were digested by restriction enzymes, BamH1, Xba1, and EcoR1, we found same size band pattern. However, this sequence was not homologous to sequence of T. castaneum PPO gene. Using the primer designed based on the sequence of D. melanogaster, 209 bp PCR product was observed.

  • This paper proposes a new quickly convergent pattern search quasi-Newton algorithm that employs the multi-step version of the Symmetric Rank One (SRI). The new algorithm works on the factorizations of the inverse Hessian approximations to make available a sequence of convergent positive bases required by the pattern search process. The algorithm, in principle, resembles that developed in [1] with multi-step methods dominating the dervation and with numerical improvements incurred, as shown by the numerical results presented herein.

  • In this letter, we present an event stream processing system that can evaluate a pattern query for a data sequence with predicates. We propose a pattern query language and develop a pattern query processing system. In our system, we propose novel techniques for run-time aggregation and negation processing and apply our system to stream data generated from vehicles to monitor unusual driving patterns.

  • Adozelesin and carzelesin are synthetic analogues of the extremely potent antitumor antibiotic CC-1065, which alkylates N3 of adenine in a consensus sequence $5^1$-(A/T)(A/T)$A^*$ ($A^*$ is the site of alkylation). We have investigated the DNA sequence selectivity of adozelesin and carzelesin by thermally ind ced DNA strand cleavage assay using radiolabeled restriction DNA fragments. An analysis of alkylation patterns shows that the consensus sequences for carzelesin and adozelesin have been found to be $5^1$-(A/T)(A/T)$A^*$ and $5^1$-(A/F)(G/C)(A/T)$A^*$. A new consensus sequence, $5^1$-(A/T)(A/T)$CA^*$, has been observed to display an additional alkylation site for adozelesin but not for carzelesin. These results indicate that the pattern of sequence selectivity induced by carzelesin is similar but not identical to those induced by adozelosin.

  • This paper presents a method for code generation of UML sequence diagrams based on message patterns. In the sequence diagrams, it is shown that messages are some types of forms typically. This paper classifies according to type as three patterns, and construct meta-information for code generation analysing structural infomation for each patterns. The meta-message of structural information (MetaMessage) is stored in the MetaMessage datastore and the meta-method information from the MetaMessage is stored in the MetaMethod datastore. And then, the structural information of MetaClass and MetaObject is constructed in each datastore too. For each pattern, this paper presents a method for code generation based on the meta information of message patterns and the syntax of target progamming language. Also, branching and looping that has been seldom handled integratedly in the previous works are handled as same as the basic patterns by classifying the branching pattern and the looping pattern for code generation integratedly.

  • Communication log data consist of communication events such as sending and receiving e-mail or instance message and visiting web sites, etc. Many countries including USA and EU enforce the retention of these data on the communication service providers for the purpose of investigating or detecting criminals through the Internet. Because size of the retained data is very large, the efficient method for extracting valuable information from the data is needed for Law Enforcement Authorities to use the retained data. This paper defines the Interactive Communication Sequence Patterns(ICSPs) that is the important information when each communication event in communication log data consists of sender, receiver, and timestamp of this event. We also define a Mining(FDICSP) problem to discover such patterns and propose a method called Fast Discovering Interactive Communication Sequence Pattern(FDICSP) to solve this problem. FDICSP focuses on the characteristics of ICS to reduce the search space when it finds longer sequences by using shorter sequences. Thus, FDICSP can find Interactive Communication Sequence Patterns efficiently.

  • This paper analyzes the recognition of driver's behavior in lane change using context-free grammar. In contrast to conventional pattern recognition techniques, context-free grammars are capable of describing features effectively that are not easily represented by finite symbols. Instead of coordinate data processing that should handle features in multiple concurrent events respectively, effective syntactic analysis was applied for patterning of symbolic sequence. The findings proposed the effective and intuitive method for drivers and researchers in driving safety field. Probabilistic parsing for the improving this research will be the future work to achieve a robust recognition.

  • Mobile IPv6 generates the loss of packets and out of sequencing when hand off, In this paper, We propose a improved hand off techniques using the mobility pattern of mobile nodes. As making group by presetting the moving range of mobile nodes, and putting buffer server in the group, the packet loss and out of packet sequence can be reduced. The proposed method prevents the out of packet sequence in If level which can be happened in the stable state, minimizes the packet re-send in TCP level. In the simulation, the proposed hand off techniques transmits packets efficiently by using the mobility pattern of mobile nodes.

  • The purpose of this research explain the meaning of the environmental design principles and cultural landscape pattern(dualistic space organization) of the Hahoe(河回:winding river village) the Yangdong(良洞) traditional village. Village's space organizations based on Shamanism, fin-yang and Five elements principle, Feng-shui idea, social system and Confucian ideas. And it were accomplish curat landscape pattern(village:form+object=pattern) through the frame of settlement space. As a central persons of villages(the Hahoe $.$ the Yangdong) construction, Suhae(西厓) experienced tough Chunghyodang - Wonjichongsa - Ogyonchongsa - Pyongsansowon channel(忠孝堂 -遠志精舍 -玉端精含 -脣山書院) and Kyomam(謙 ) experienced tough Yangjindang - Binyeonchongsa - Kyomamchongsa - Hwachonsodang(養眞堂 - 賓淵精舍 - 謙庵f精舍 - 花川書堂) channel. Also Woojae(愚齋) experienced tough Suhbackdang - Khankachung - Dongkangsowon(書百堂 - 觀稼停 - 東江書院) and Hoejae(晦齋) experienced tough Moochumdang - Hyangdan - Oaksansowon(無添堂 - 香壇 - 玉山書院). It is space organization of themselves interact contrast and sequence principles with competition in good faith. And ecological art-space, that is, environmental spare organizations of traditional village has been reflected harmony between nature and artificiality, spatial rhythm and sequence, spatial hierarchy between upper classes and humble class, permeability space, asymmetrical balance, aesthetic space perception. The humble classes hold a ceremony Hahoe's Pyolsingut-Talnori(maskdance drama), Dangjae(堂祭:religious service) at the Dang(堂:shamanism spot) and Yangdong's Sohraesulnori, Hohminori. And the upper class hold a ceremony Hahoe's Julbulnori and Yangdong's Chungjanori connected with culture of confucianism. Specially, the cultural structure cf the village is evidence of a contrast between the upper class and the humble classes, time, method and location of ceremony(performance).
