Kajian ini membahas wacana iklan jasa boga dalam media luar ruang. Iklan merupakan sebuah sarana yang dipandang efektif dalam menyampaikan informasi. Iklan jasa boga menarik untuk dikaji karena memperlihatkan kekhasan dalam pemakaian bahasa. Kajian bertujuan mendeskripsikan slot-slot wacana jasa boga dan strategi pembentuk slot atau pengisi slot pada iklan jasa boga di media luar ruang. Kajian ini menggunakan pendekatan struktural dan bersifat deskriptif kualitatif. Penelitian ini menggunakan metode observasi. Peneliti mengamati secara langsung iklan-iklan media luar ruang di DIY. Observasi menerapkan teknik simak dan rekam visual. Metode dan teknik analisis yang digunakan untuk menjawab permasalahan ialah metode agih dengan teknik sisip dan balik. Hasil penelitian ini menunjukkan bahwa wacana iklan boga menghasilkan empat jenis slot. Slot nama dapat berbentuk (1) akronim, (2) singkatan, (2) nama diri, dan (4) nama lokasi. Slot spesifikasi dapat bersifat menyangatkan atau mengedepankan kekhasan daerah. Slot atribusi menyiratkan bentuk slogan. Slot alamat berisi keterangan alamat rumah dan nomor telepon. Aspek permainan bahasa berkenaan dengan penyimpangan ejaan, yaitu pemakaian huruf kapital dan penulisan kata.This study discusses about food service advertisement discourse on outdoor media. Advertisement is one of effective facility in delivering information. The advertisement is interesting to study for its particularity in language use. The study aims to describe discourse plots on food service and strategy to form plot or plot insert on advertisement of food service on outdoor media. This study uses structural and qualitative descriptive approach. This study uses observation mode by observing directly to outdoor advertisement media in DIY. The observation uses listening and visual recording. Method and analysis technique to answer the problem is distributional using inserting and reversing technique. The result shows that food service discourse produces four types of slots as (1) acronym, (2) abbreviation, (3) self name, and (4) location name. Specification slot emphasizes locality particularity. Atritributive slot shows slogan form. Address slot contains description of house address and telephone number. Language playing aspect is dealing with spelling split, that is alphabetical use and word writing.

Introduction. Electromagnetic safety of power grid facilities staff requires the exclusion of electromagnetic fields (EMF) harmful effects. EMF is evaluated by 50 Hz electric and magnetic fields (EF and MF) values in the framework of working conditions special assessment, and very rarely the analysis of the electromagnetic environment (EME) is carried out in depth. The aim of the study - EME hygienic assessment of power grid EHV facilities personnel workplace with adequate 50 Hz EF and MF levels evaluation as well as the analysis of EF and MF in the frequency range from 5 Hz to 500 Hz amplitude-frequency characteristics. Materials and methods. 50 Hz EF and MF values assessment was carried out on open switchgears (S) of substations and within sanitary breaks of 500 and 750 kV overhead power transmission lines (OTL). Measurements along to OTL trasses was performed using matrix-based method. Measurements and analysis of EF and MF values in 5-500 Hz frequency range amplitude-frequency characteristics were performed in the territory of 500 and 750 kV S. Results. Power frequency 50 Hz measurements results at 500 and 750 kV S ground-level personnel workplaces showed the presence of an excess of permissible limit values by EF intensity and the absence of an excess by MF. The measured EF values within 500 and 750 kV OTL sanitary gaps require limiting the working time of linemen due to the excess of the hygienic norms for full work shift, while the MP levels were almost completely within the standard values for persons not occupationally connected with electrical installations maintenance. MF and EE frequency range from 50 Hz to 500 Hz spectral characteristics analysis showed that 3rd harmonic percentage does not exceed 2.5% for EF and 6% for MF of the main level, the level of the 5th harmonic does not exceed 1% for EF and 3.5% for MF, the level of the 7th harmonic does not exceed 0.2% for EF and 0.8% for MF. These data show despite its low levels the contribution of MF different harmonics in a possible adverse impact on humane than EF corresponding harmonics. Conclusions. There was the confirmation of the previously justified use of the "matrix" scheme for of EF and MF values measurement along OTL routes. The relevance of to EF and MF all frequency components expos ure assessing possible health risk in extremely high voltage S territories and under OTL, based on international recommendations due to the lack of sanitary regulations in the Russian Federation for >50 Hz-30 kHz EF and MF, is shown.
