A graph theoretical model called Roman domination in graphs originates from the historical background that any undefended place (with no legions) of the Roman Empire must be protected by a stronger neighbor place (having two legions). It is applicable to military and commercial decision-making problems. A Roman dominating function for a graph G = (V, E) is a function $f:V{\rightarrow}\{0,1,2\}$ such that every vertex v with f(v)=0 has at least a neighbor w in G for which f(w)=2. The Roman domination number of a graph is the minimum weight ${\sum}_{v{\in}V}\;f(v)$ of a Roman dominating function. In order to deal a problem of a Roman domination-type defensive strategy under multiple simultaneous attacks, ${\acute{A}}lvarez$-Ruiz et al. [1] initiated the study of a new parameter related to Roman dominating function, which is called strong Roman domination. ${\acute{A}}lvarez$-Ruiz et al. posed the following problem: Characterize the graphs G with equal strong Roman domination number and Roman domination number. In this paper, we construct a family of trees. We prove that for a tree, its strong Roman dominance number and Roman dominance number are equal if and only if the tree belongs to this family of trees.

Let k be a positive integer, and let G be a simple graph with vertex set V (G). A Roman k-dominating function on G is a function f : V (G) $\rightarrow$ {0, 1, 2} such that every vertex u for which f(u) = 0 is adjacent to at least k vertices $\upsilon_1,\;\upsilon_2,\;{\ldots},\;\upsilon_k$ with $f(\upsilon_i)$ = 2 for i = 1, 2, $\ldot$, k. The weight of a Roman k-dominating function is the value f(V (G)) = $\sum_{u{\in}v(G)}$ f(u). The minimum weight of a Roman k-dominating function on a graph G is called the Roman k-domination number ${\gamma}_{kR}$(G) of G. Note that the Roman 1-domination number $\gamma_{1R}$(G) is the usual Roman domination number $\gamma_R$(G). In this paper, we investigate the properties of the Roman k-domination number. Some of our results extend these one given by Cockayne, Dreyer Jr., S. M. Hedetniemi, and S. T. Hedetniemi [2] in 2004 for the Roman domination number.

A paleoparasitological study was carried out on 2 lead coffins recovered from the Roman site of Jaunay-Clan (near Poitiers, France). For the first time, this particular type of burial gave positive parasitological results, and eggs of the whipworm Trichuris trichiura were identified in 1 individual. In the present case, thanatomorphose associated with funerary practices may explain the scarcity of the recovered eggs. However, human whipworm has now been observed in 9 individuals dated to the Roman period. The very high frequency of Trichuris sp. eggs in Roman archaeological sites (up to 80%) suggests that fecal peril, hygiene, and waste management were problematic during this period. Finally, due to the fact that very few analyses have been conducted on human bodies dated to the Roman period, more analyses must be performed in the future to provide further information about diseases in the Roman world.

In the field of oriental medicine, many researchers head for the aim of standardization. To achieve this aim, oriental medical researchers have been carried out experimental research, statistical research, clinical research, philological research, etc., and, have published their results to journals. But, the declaration of Roman name of herbal formula is not united each other, on several article. So, we should prepare database to search in domestic and overseas, and should consider compatibility of internationally used search system. Also, it is need to use appropriate roman letters in oriental medical terms for people can use easily. We inquired the type of roman letters in the name of formula of article that were carried oriental medical journal, to find out appropriate roman letters and to the demands of the times. There were many cases that Korean name of formula is not correspond to the declaration of Korea roman letters. Also, the declaration of roman letters for preparation like as tang(湯), san(散), hwan(丸) etc. are not standardized. To facilitate making database and forming search system, now we suggest that we can standardize the declaration of Korea roman letters by using of Hangul(한글) word processor's toolbar which has transformation of roman letters.

The origin of the Roman public basilica is Rome's indigenous style morphologically but actually it seems that developed the Greek semi-open style stoa into the Roman practical interior space. In the early ages, the arrangement of Roman forum had been planned high symbolical temple as the center but gradually changed into the basilica centered which were used often by citizen. Through the Roman period, the important types of early Roman basilica have Fano basilica in the first century BC, Pompei basilica of mid period in the first century AD, Doclear basilica with apse as late type in the second century AD. Pompei type well characterized the feature of Roman public basilica among them. The result of the floor plan analysis shows that the long side access to the interior space is over 76 percent of examples and nearly 70 percent have no apse and the average of vertical horizontal length ratio presents as 1:2.3. The typical plan of Roman public basilica can be defined that most of access are being entered from one of the long side, and most of basilica have no apse, and normally having inner columns arranged in one or more concentric rectangles around nave as a center.

The purpose of this paper is the study on the architectural characteristics revived from the roman architecture, focused on the early renaissance architecture building. The results of study are as follow: 1. The composition system of Domus which is formed of urban house in the Roman period is presented by spatial arrangement of palace architecture centering around atrium in the Renaissance period. Thus plan type of Domus is used by atrium from which is composed of peristyle from the palace and villa in the Renaissance period. 2. The circular temple in the Roman period is composed of element such as podium, stair, peristyle centering around the basic circular plan. Bramante planed to revive above elements for the Tempietto to concept from the circular temple in the Roman period. 3. The triumphal arch in the Roman period is strong monument to the independent building in the city, but thus arch is used of church facade as the important example which is composed with building elevation in the Renaissance period. 4. The composition system and element of Roman temple which is planned to rectangular plan is composed of high podium, stair, portico, prostyle and pediment. The facade plan of church is used by the partial elements and total elements perfectly from the temple in the Roman period. 5. The linearly successive and repetitive composition which is composition system and element of aqueduct arches of same dimension shows to the palace facade, arcade for gallery space and side elevation plan of S.Fracesco church. 6. Such as background of Colloseum, Rucellai palace can be called good example which is created by the new architectural form to the creative starting point from the classical architecture from.

For a rule-based conversion of Hangout into the Roman alphabet rather than a word-for-word conversion, one must come up with a faultless model for the Korean standard pronunciation rules, which are the basis of the Romanization. It is on this foundation that the Korean-Roman alphabet conversion table can be created. For linguistic modeling using PetriNet, modeling boundary and notation of modeling can be defined. In order to describe PetriNet, which is a dynamic modeling tool, as a static one, one can model the standard Korean pronunciation rules and the Hangout-Roman alphabet notation by conversion into incident matrix Thus, this research attempts to develop a mathematical modeling tool for a natural language using PetriNet, and create a Korean-Roman alphabet conversion table.

본 논문에서는 한글-로마자 인명 변환을 다루며, 기존에 사용되고 있는 다양한 표기를 인정하고 인명 변환의 사용 빈도에 따라 결과를 제공함을 목표로 한다. 한글-로마자 인명 표기가 다양해진 이유는 크게 두 가지이다. 첫째로 국내외에서 만들어진 다양한 표기법의 무분별한 사용이며, 둘째로 현행표기법에서의 관습적인 표기를 허용하기 때문이다. 이런 이유로 한글 인명 하나에도 다양한 로마자 표기가 가능해졌다. 시스템에서는 400만 명의 인명 데이터를 통계 사전으로 구축하여 변환한다. 첫 단계에서는 성씨의 매칭과정을 통해 인명 유무를 판단하고, 두 번째 단계에서는 이름 전체를 통계사전에서 비교하여 변환한다. 마지막 단계에서는 이름의 음절을 비교 후 변환하여 결과를 사용 빈도에 따라 순위로 제공한다. 본 논문에서는 기존의 웹에서 서비스 중인 시스템과 비교하여 성능을 측정하였으며, 타 시스템에 비해서 다소 높은 성능을 보였다.

본 연구는 대 플리니우스의 『자연사』 속 정원 관련 문헌을 중심으로 고대 로마 시대의 정원관을 탐색함을 목표로 한다. 고대 로마 정원의 유형과 성격, 형태 등은 이후 서양 정원의 발달에 큰 영향을 미쳤고, 플리니우스 등이 집필한 실용적이고 전문적인 문헌이 큰 영향을 미쳤다. 『자연사』와 관련 문헌, 사료를 중심으로 진행된 본 연구에서는 로마 정원의 형태나 양식적 특징에 대한 이해를 바탕으로, 이들 문헌에 투영된 정원관을 탐색하였다. 『자연사』뿐 아니라 고대 로마 시대에 작성된 정원, 혹은 농업 이론서는 관념적인 자연이나 예술로서의 정원보다는 실용적인 생산 공간을 주로 다룬다는 특징이 있다. 『자연사』에서 정원 연구와 관련된 식물학 부분 또한 즐거움보다는 유용함을 위주로 기술되었고, 플리니우스 또한 실용적인 정원인 호르투스를 전제로 논의를 전개하였다. 고대 로마 사회에서 정원은 실용적인 생산과 휴식의 공간일 뿐 아니라, 한 시대의 이상을 재현, 혹은 실천하는 장소였다. 플리니우스를 비롯한 로마의 지배세력과 지식인들은 그들이 지배하는 전 세계에 대한 앎을 포괄하고, 이를 통해 로마 대제국의 비전을 실현하고자 하는 에피스테메를 공유했다. 플리니우스는 『자연사』를 통해 당대의 유용한 지식을 로마 제국이라는 방대한 문명 세계로 포괄하고자 했고, 정원은 그 이상을 실천하는 중요한 장소였다.
