Public holidays are periods set aside by nations or states to observe particular events like national days, independence anniversary or religious festivals. These days are different from the usual periods of statutory leave or vacation provided for workers in the collective agreement or rule of engagement at the point of entry. These periods of leave enjoyed by workers include annual vacation, casual leave, sick leave, maternity leave, paternity leave and others as may be recognized within an establishment. Individual worker's period of leave is personal and at the discretion of the worker or the organization as the case may be, but public holidays involve the stoppage of work by the entire workforce within the period it would last. Nigeria observes many public holidays some of which, at times, are unplanned for by the people. This has attracted arguments for and against on the basis that these holidays are too many and detrimental to productivity and the national economy. Using secondary data, this paper examines the issue and opines that there is the need to review these public holidays with a view to halting their negative effects on the nation's economy. Also, measures to manage these holidays in line with constitutional provisions are espoused.

Bayesian networks have been used in studying and simulating causal inferences by using the probability function distributed over the variables consisting of inquiry space. The focus of the debates concerning Bayesian networks is the causal Markov condition that constrains the probabilistic independence between all the variables which are not in the causal relations. Cartwright, a strong critic about the Bayesian network theory, argues that the causal Markov condition cannot hold in indeterministic systems, so it cannot be a valid principle for causal inferences. The purpose of the paper is to explore whether her argument on the causal Markov condition is valid. Mainly, I shall argue that it is possible for upholders of the causal Markov condition to respond properly the criticism of Cartwright through the continuous causal model that permits the infinite sequence of causal events.

The rise of the Robo-advisor represents one of the most profound shifts in FinTech. It also raises concerns about their financial management. As the most Robo-Advisors utilize ETFs, we seek to determine the appropriate risk management model in estimating 95% Value-at-Risk (VaR) and 99% VaR in this paper. The GARCH and the Markov regime wwitching GARCH are evaluated in terms of the accuracy of probability, the independence of extreme events occurrence and both. The result shows that the Markov regime switching GARCH can be a good ETF risk management tool since it can reflect financial market structural changes into the volatility.

As the importance of documented fact has weakened in historical dramas, the combination with other genres has become prominent. By reviewing the way romance is dealt with in historical dramas, this research examines how the properties of historical events adopted by historical dramas are related to the motif of love, and how the narrative of love and romance contributes to the historical effects, with a focus on the television drama Mr. Sunshine. Mr. Sunshine is the first historical drama written by Kim Eun-sook, combining deliberately rearranged history with the writer's unique grammar of romance. The failed resistance movement of the righteous army in the drama is matched with the love that cannot be achieved based on self-negation. The drama, which deals with the tyranny of Japanese imperialism and the independence of Joseon, fictionalizes key characters and events, transforming the desire of love into the passion of patriotism. Romance in Mr. Sunshine serves as a catalyst for emphasizing the tragedy of historical events and reconstitutes cultural memories. In historical dramas, the fictional plot of romance leads viewers to reflect on human life in history that flows from the past to the future. How does an individual's inner feelings contribute to the historical representation? This research is significant as it is the first attempt to examine the relationship between historical drama and romance in various ways.

The purpose of this study is to investigate about security service history on 1930s in Korea. This study used materials by historical facts for the regulations, books and newspapers in 1930s. In 1930s, security service was unknown details of the historical contents so far. There are four parts conclusion of this study: police department of provisional government, security service agency in the provisional government, security service agents of an independence movement, the general society of Korea. Firstly, Korean regional government in Manchuria, which Kokminbu(國民府) organized the security service agency(警護局) for protect government and public security. Most importantly, the security service agency appearanced an important place which were the independence movement and self-governing administration for Koreans in Manchuria. And the security service agency was required by the security service regulations(警護條例) as law. Secondly, diversity activities of security service in police were exposed the duty as 'car escort service(車輛警護)' for offenders, the 'township office guard' from mobsters, 'woodland protect service(林野警護團)' for fire-raisers. security service as police officer were widely application for protection and safety from danger. Thirdly, Mass society was needed to service for public security in daily events such as 'noted singer meeting', 'funeral procession to the graveyard', 'athletic meeting' as private establishment of security service agency in nowadays. people were wanted the private security service(私警護) from 1930s to present. Fourthly, Overseas security service mentioned in attack of politician, protect from poison and security service about train vessel fleet. In 1930s, security service is comprehensive protection which were not only bodyguard, but also safeguard for hazardous materials.

Many researchers have found that one of the most important characteristics of the structure of linkage disequilibrium is that the human genome can be divided into non-overlapping block partitions in which only a small number of haplotypes are observed. The location and distribution of haplotype blocks can be seen as a population property influenced by population genetic events such as selection, mutation, recombination and population structure. In this study, we investigate the effects of the density of markers relative to the full set of all polymorphisms in the region on the results of haplotype partitioning for five popular haplotype block partition methods: three methods in Haploview (confidence interval, four gamete test, and solid spine), MIG++ implemented in PLINK 1.9 and S-MIG++. We used several experimental datasets obtained by sampling subsets of single nucleotide polymorphism (SNP) markers of chromosome 22 region in the 1000 Genomes Project data and also the HapMap phase 3 data to compare the results of haplotype block partitions by five methods. With decreasing sampling ratio down to 20% of the original SNP markers, the total number of haplotype blocks decreases and the length of haplotype blocks increases for all algorithms. When we examined the marker-independence of the haplotype block locations constructed from the datasets of different density, the results using below 50% of the entire SNP markers were very different from the results using the entire SNP markers. We conclude that the haplotype block construction results should be used and interpreted carefully depending on the selection of markers and the purpose of the study.

This paper aims at comparing the metanarrative and East Timor's local narrative in Indonesia during the Suharto's regime. Although these history writings have different political goals, the patterns of writings are ironically similar. Both of the history writings show strong nationalistic history writing patterns. Yet, in the writings, these histories place different interpretations on the historical events. In the metanarrative, local dynamics are seen through the diagrams of the nation and nationhood. This narrative finds the roots of the "ethnie" from some kingdoms in Java and Sumatra. These kingdoms, which throve based on the Hindu-Buddhist culture, achieved a territorial unity to a degree, covering some parts of Java and Sumatra. The glorious past disappeared with the advent of the colonial rule. The metanarrative then emphasizes the unity of the ethnic groups in the archipelago, which fiercely resisted against the colonial exploitation and oppression. By this, these ethnic groups were defined as "the masses," the collective identity, which had a same goal to achieve the national independence. In addition, some local histories, which took positive attitudes toward the European forces, were simply left out from the metanarrative. All the separatist movements taking place in the republic were also described as the anti-unifying forces. On the other hand, the goal of the history-writing in East Timor was to enhance the sense of nationalism and create the perception of the "East Timorese." The fundamental aim was the separation from Indonesia. In the narrative, the nationalist politicians overcame the problem of the non-existence of any memories of the glorious past with the awakening of the idea of "the imagined gloriousness of the past if there was no colonial rule." In addition, the narrative overemphasizes the memory of the colonial rule for 450 years under the Portuguese rule in order to stress the fact that it was the colony of Portugal, not of the Netherlands. Finally, the narrative shows how the East Timorese collectively fell to the status of slaves. By this, the political leaders of East Timor evoked the notion that it was recolonized by Indonesia, under which the East Timorese were demoted to the status of slaves. This notion of "slave-master" relationship then became the motives for the independence struggles in East Timor.

A tendency to ignore the existence of public space in Korea under the Japanese colonial period seems to be driven from nationalist historiography in which all historical events under the colonial power have to be interpreted in terms of militant controls and resistances against them. Historical approach to mass media of that period has lasted to be saturated with the tendency and forced history students to stick to the nationalist guidelines. Struggles against Japanese imperial power by national-capital-operated newspaper have been a main menu of studies on the period's communication. The media were often hailed as fighting the colonial power for nation's independence. The present thesis aims to criticize the nationalist point of view and to reveal that nationalist interpretations may miss a variety of historical information. Even under the severe surveillance of colonial police some journalists tried either to inform officially or to smuggle into informed groups. The colonized society could experienced fields of public-ness throughout the practices of such as media fields, cultural fields, political fields. Those fields, of course, didn't come from the graceful favor of the colonial power but from the construction of the colonized. The public-ness seemed to be born for the easiness of control, but became later a constructed field of public-ness with which the colonized semiotically wrestled the power and grew a modern type of political (un)consciousness. Depicting what happened just before 815 liberation day in Korea the present paper showed that the less nationalist historiography can render help to those seeking political practices of the colonized in a micro-level.
